April brings flurry of spring migrants to region

Louisiana Waterthrush

The Louisiana waterthrush nests along fast-moving streams in the area while the Northern waterthrush does not breed in the region.

I’m always happy for the arrival of April because I know the month hails the arrival of some of my favorite birds. The roughly 50 species of New World warblers that occur in the Eastern United States have captivated me from the time I first picked up a pair of binoculars. The warblers offer color, energy, complex songs and much more for the bird enthusiast to enjoy.

The month started out with my first sighting of a purple finch for the year. The finch must have been a harbinger of birds to come because in quick succession I observed many early migrants, including brown thrasher, blue-headed vireo, blue-gray gnatcatcher and chipping sparrow, as well as several warblers.

The first warbler to arrive in the woods around my home this year was a singing male black-throated green warbler. Three others — black-and-white warbler, yellow-throated warbler and Louisiana waterthrush — followed quickly after my sighting of the black-throated green warbler.

The Louisiana waterthrush stood out among these early observations. This warbler is a specialist of creeks and streams, and my sighting took place near a roaring creek swollen by a rainy spring. This water-loving warbler also has a loud, ringing song that can still be hard to hear because of the fact the bird is usually near the background noise of rushing water.

While many warblers have shown signs of decline in recent years, the Louisiana waterthrush appears to have bucked that trend. According to the website, “All About Birds,” Louisiana waterthrush populations were stable between 1966 and 2015, based on statistics from the North American Breeding Bird Survey. Partners in Flight, a network of organizations engaged in all aspects of avian conservation, estimates a global breeding population of 360,000, with almost all of those individuals spending at least part of the year in the United States. About a quarter of the population retreats into Mexico during the winter season. The rest winter in Florida and some of the Gulf Coast states, as well as the islands of the Caribbean.

While most songbirds are fortunate to survive two or three years in the wild, at least one Louisiana waterthrush lived to the age of at least 11 years and 11 months. The bird, a male, was seen in New Jersey in the wild and identified by a band on one of his legs. He had been banded in the same state, according to the website, “All About Birds.”

The waterthrushes are the only two species in the genus Parkesia, so named to honor American ornithologist Kenneth C. Parkes, who was for many years curator of birds at Carnegie Museum of Natural History. The common name of the Louisiana waterthrush is not a very apt one, as this bird does not have any special affinity for the state of Louisiana. Someone collected some of the early specimens of the Louisiana waterthrush in its namesake location, and the name has stuck through the years.

The only other warbler in the genus Parkesia is the Northern waterthrush which, unlike its relative, likes to live near quiet, sedate pools, ponds and bogs, not rushing streams.

Hummingbirds getting closer to region

Tommy and Virginia Curtis of Smithville, Tennessee, reported their first ruby-throated hummingbirds of the spring on the email group, “TN-Birds.” The hummingbird arrived on April 7.

“We had two male ruby-throated hummingbirds arrive late Sunday afternoon,” they wrote in their email. “That is a little later than the April 1 arrival times in the past.”

The two visitors had apparently agreed to co-exist.

“So far they are eating peacefully, and neither is attacking or dominating the one feeder,” the couple reported. “We keep wondering when the white-throated sparrows and dark-eyed juncos plan to leave, as we have had many of them all winter.”

The couple also shared that they have been hosting a small flock of purple finches. “They normally don’t show up at our feeders unless there is snow on the ground, but we have enjoyed seeing them daily,” they wrote in their email.

Of course, the Curtises live in DeKalb County in Middle Tennessee. As of press time, I still haven’t received any reports of hummingbirds arriving in East Tennessee or Southwest Virginia. I’m confident these tiny winged gems will arrive soon. I hope to update on hummingbird arrivals in next week’s column.

Remember to share your hummingbird sighting by emailing me the date and time of the sighting to ahoodedwarbler@aol.com. I’m also on Facebook should anyone want to contact me through that social media platform.

Feeding birds can draw some unwelcome guests

Squirrel-AttackPhoto by Dianna Lynne • Leaping onto a fully stocked feeder, an Eastern gray squirrel scatters seeds in all directions. The unconquerable squirrel is one of the most unwanted guests at many bird-feeding stations.

 

The winter bird-feeding season is coming to a close, but there’s no need to pull the welcome mat completely. Some of our summer visitors appreciate some supplemental food. Of course, there’s less need for our offerings during warm weather when insects and other food sources are readily available.

People in Great Britain spend 200 million pounds per year on wild bird food. In the United States, people are spending $4 billion each year on feed for the birds. Another $800 million in spending goes to feeders, bird baths and other accessories used to attract wild birds.

People have been feeding birds in the United States of America since before it was a nation. The father of our country, George Washington, fed wild birds at his home, Mount Vernon. The great writer and thinker Henry David Thoreau fed the birds and learned to identify many of the birds around Walden Pond in Massachusetts. Poet Emily Dickinson tossed crumbs to sparrows and then turned those special moments with her feathered friends into poetry.

Since the time of Washington, Thoreau and Dickinson, if not before, Americans have been supplying food, as well as shelter and water, to persuade birds to bring themselves closer. In return, we enjoy their color, their interesting behavior, their songs, and much more.

I continue feeding during the warmer months, although I do cut back on the quantity of my offerings. One of the best bonuses for engaging in year-round bird feeding is the chance to see parent birds bring their offspring to feeders to introduce them to human-offered fare. Be aware, however, that when you put out a table offering free food, you’re bound to attract some unexpected guests. Sometimes those unanticipated visitors can wreak havoc on the smooth management of a feeding station for your birds.

Here is my version of the Top 5 candidates for a “Not Welcome” list of the wildlife most people would prefer not to entertain at their feeders.

Hawks

The raptors are, of course, birds themselves. Therein rests the irony. Flocks of birds active around feeders are like ringing a dinner bell for some raptors, which have learned that songbirds in such situations on occasion make easy pickings.

It’s not any single raptor that can be identified as the most obvious threat to songbirds. Species such as American kestrel, sharp-shinned hawk, Cooper’s hawk, red-shouldered hawk, merlin, peregrine falcon and red-tailed hawk will prey on their fellow birds if given ample opportunity.

rthawk-one

Photo by Bryan Stevens • Raptors, like this red-tailed hawk, can cause concern when they take up residence near a feeder in a yard or garden.

If a hawk does begin to show interest in your feeders, it may be necessary to curtail or even cease feeding songbirds until after the raptor loses interest and moves on to other hunting grounds.

I hesitate to even place raptors on this list because I believe that every bird is a wonderful creation. It’s best to remember that hawks view smaller birds flocking to a feeder in the same way those small songbirds view the abundance of seeds. For both hawks and songbirds, our offerings represent easy meals. It’s not easy, but the best choice is to co-exist — if not at peace, then at terms with nature’s reality.

Opossums

The Virginia opossum, also known as the North American opossum, or simply “possum,” is often overlooked because its raids on feeders take place after dark. Although the opossum has 50 teeth (that’s more than any other North American mammal has) in its jaws, it shares the night with other active omnivores, including bears and raccoons.

Regardless of its toothy grin, the possum is not adept as hulling sunflower seeds. The telltale sign that a possum is raiding your feeders involves the discovery of little piles of pulped sunflower seeds, hull and all, in your feeder or on the ground beneath it. The possum pulverizes the sunflower seed and evidently tries to extract what nutritional content it can. Of course, suet, nuts and other feeder fare are on the possum’s menu.

This particular possum is the only marsupial found north of Mexico. The continent of Australia is more famous for its marsupials, which include kangaroos, wallabies and wombats.

Raccoons

These masked, ring-tailed bandits are the bane of many a person who enjoys feeding birds. While they primarily restrict their raids to the hours between sunset and dawn, some emboldened raccoons will occasionally become brazen enough to stake a claim to feeders in broad daylight. A couple of years ago, a trio of young raccoons arrived early in the evening with plenty of daylight remaining to feed in the feeders while I watched from a nearby lawn chair with my binoculars.

Raccoons will also spirit away feeders. I’ve found hummingbird feeders, suet feeders and small plastic feeders carried a good distance into the woods before the thieving raccoon dropped them. The stolen items are usually damaged but, on occasion, I’ve recovered some of my items that were more or less no worse for the wear.

On one occasion, a crafty raccoon managed to remove a sunflower seed feeder from its branch on a tree outside one of my windows, I later found the portly critter reclining lazily on his back wedged between the trunk and a branch high on a nearby tree, holding the feeder in one arm and reaching into it with the other like a person eating popcorn.

Raccoons are highly intelligent and inquisitive, which only makes them more difficult to discourage from raiding feeders. They can be amusing and entertaining in their own right, but it’s best not to encourage their visits. If they prove too persistent, cease feeding birds until the raccoons have moved to a new location.

Bears

A visit from a black bear is hard to miss. With their brute strength, bears are capable of mangling and destroying even the most sturdily constructed of bird feeders. While there are many other unwanted feeder guests, none can match the bear for its sheer capacity for destruction. Black bears can weigh between 200 to 600 pounds, so it’s not hard to imagine their potential for wreaking havoc.

Amanda Austwick lives in Flag Pond, Tennessee. She is a dedicated feeder of our feathered friends, which has led to repeated incidents with problem bears over the years. Amanda lives within the official boundaries of the Cherokee National Forest. Black bears have been thriving in the Cherokee National Forest, as well as throughout the southeastern United States.

When I first corresponded with Amanda several years ago, she was writing to me about a bear attack on her feeders. “One feeder was completely bent over on the ground,” she wrote. I also pointed out that the bear is actually just feeding on the seed. The damage to the feeder is a by-product caused by the fact bears probably don’t know their own strength.

I’ve not gone completely unscathed when it comes to bears and my feeders. Several years ago I owned a nice feeder with a metal meshwork used for holding shelled peanuts, which are loved by birds such as chickadees, titmice, nuthatches and woodpeckers. I woke one morning to find the feeder had been mangled into the equivalent shape of a pretzel.

Compared to the stories told by Amanda, as well as other people who have shared their own bear tales over the years, I got off lucky to only lose a single feeder to a bear. Brookie and Jean Potter, friends who live near Wilbur Lake in Carter County, Tennessee, have had to innovate to stay one step ahead of the bears living in proximity to them. Brookie managed to raise their feeders beyond a bear’s reach using a complicated system of poles and pulleys.

If such proactive measures are not something one wishes to do, there’s one simple step that can be taken. People can bring in their feeders at night to ensure there’s nothing left outdoors to attract the attention of a meandering bear. Bears are omnivores, eating a varied diet ranging from insects and fish to amphibians and bird eggs. When a bear finds a bird feeder, they’re happy to include sunflower seeds or other such fare in their diet. When such food is no longer available, they’re likely to move on.

Squirrels

They may not match a black bear for sheer destructive capability, but I regard the Eastern gray squirrel as Public Enemy Number One when it comes to having peace and tranquility at a bird-feeding station. What justifies this ranking? It’s simple, really. I know of no sure-fire way to deny a hungry and determined squirrel access to any type of feeder. It’s possible to slow them down, but I think the best we can do is maintain an uneasy truce of co-existence with squirrels.

I wouldn’t begrudge the squirrels some bird seed if they didn’t show such ingratitude by gnawing on feeders. With their sharp incisors, squirrels can chew up and spit out plastic and even wood feeders. More expensive feeders made of ceramics, metal and glass are immune to the same type of squirrel vandalism.

Although I’ve not tried it, I’ve heard that sunflower seed laced with capsaicin will deter squirrels. This spicy substance is even used to deter such large mammals as elephants and grizzly bears. Capsaicin, which is derived from hot peppers, reacts entirely differently with birds. While many mammals will avoid food containing even minute amounts of capsaicin, birds will readily consume it. The difference seems to be that bird receptor cells are largely insensitive to capsaicin.

••••••

To be sure, I could have added some other wildlife species to the list. White-tailed deer can graze on flowers planted for the benefit of hummingbirds. Deer have even been documented eating the eggs of songbirds, perhaps more for the calcium shell than any other reason. Chipmunks are almost as wily as squirrels, but they’re cuter and non-destructive. Insects, such as bees and hornets, can overwhelm sugar water feeders intended for hummingbirds.

Don’t even get me started on stray cats! A few years back, a study by researchers from the Smithsonian’s Migratory Bird Center and the U.S. Fish and Wildlife Center found that between 1.4 to 3.7 billion birds lose their lives to cats each year in the United States. In addition to birds, cats kill billions of small mammals — shrews, voles, mice, rabbits — every year. Most of the carnage is committed by feral or stray cats, not house cats. My own two cats are kept indoors to avoid contributing to the problem.

Prepare to welcome returning hummingbirds as migrating birds make their way back

Rubythroat-TheSoarNet

Photo by TheSOARnet / Pixabay.com • Male ruby-throated hummingbirds usually migrate ahead of females. These tiny birds must cross the Gulf of Mexico, without stopping, to reach their nesting grounds in the eastern United States. The journey across the Gulf can take them 18 to 22 hours, dependent on weather conditions.

As it has done for many years now, the website journeynorth.org is tracking the progress of ruby-throated hummingbirds as they return to the United States.

Most of the first sightings of hummingbirds made each spring are of male hummingbirds. The males arrive first so they can find and defend a choice territory for the purpose of attracting females. Indeed, there are many more sightings this week for male ruby-throated hummingbirds from Journey North citizen scientists who live along the Gulf Coast states.

Hummingbird-Ventral

On Facebook, I have been doing my own tracking based on posts from friends living farther south. For instance, Marcie McGehee Daniels in Summerville, South Carolina, made a Facebook post on March 22 to share news of her first-of-season ruby-throated hummingbird.

“He drank for a few seconds and then rested in the shade for about 10 minutes, worn out from his trip!” Marcie posted on her Facebook page. She also posted a fantastic photo of the intrepid migrant.

As demonstrated by Marcie’s post, the migration of ruby-throated hummingbirds is drawing closer to our region. They cross the Gulf of Mexico without stopping to reach the Gulf States. Once they make that difficult flight, they will spend some time recuperating before they spread out to make their way northward. Residents in Virginia, Tennessee and North Carolina should soon be making their first sightings of ruby-throated hummingbirds since these tiny flying gems departed last October.

Ruby-throated-WILLOWS

Photo by Bryan Stevens • Numbers of ruby-throated hummingbirds in the region tend to fluctuate each year, but people should see a spike in their numbers as the hummingbirds pass through the region this month as they migrate north for another nesting season.

On a recent visit to Fripp Island, South Carolina, I didn’t see any ruby-throated hummingbirds, but I did observe other birds that reminded me that many of my favorite birds should be returning to my home within the next few weeks. I enjoyed sightings of several species of warblers, as well as various shorebirds. Many warblers return to the region in April, and shorebirds may make migration stops at area lakes and rivers as they push rapidly toward breeding grounds in regions far to the north in Canada and Alaska.

Some of the first of the resident summer birds to return to the region each year includes species such as Louisiana waterthrush, brown thrasher, chipping sparrow, tree swallow and blue-gray gnatcatcher. Not too long after these “early birds” have returned, people can expect to start seeing the vanguard of the ruby-throated hummingbird spring migration as these tiny birds, which weigh no more than a nickel, return to their summer nesting grounds across the eastern United States and Canada.

As one might imagine, such tiny birds face a range of threats. In addition to offering sugar water feeders and planting gardens with nectar-bearing plants, there are other ways to help ruby-throated hummingbirds thrive.

The American Bird Conservancy recommends paying attention to our buying habits. In the winter months when they are far from their summer homes, ruby-throated hummingbirds are known to winter on shade coffee farms. Unlike today’s typical “sun” coffee farm, which razes all trees but the coffee itself, these traditional farms grow coffee in the shade of native trees. By doing so, they produce superior coffee and provide habitat for dozens of migratory songbirds, according to the ABC.

The importance of shade coffee for migratory birds was confirmed by naturalists Kenn and Kim Kaufman, who estimated that a single shade coffee farm in Nicaragua sheltered more than 1,200 migratory bird species—including the ruby-throated hummingbird—on just 90 acres. The ABC notes that buying bird-friendly coffee is an easy way people can help hummingbirds and many other migratory birds.

rufous-oct13

While the eastern United States is home only to the ruby-throated hummingbird as a nesting hummingbird species, the western half of the United States and Canada can claim about a dozen nesting species, including rufous hummingbird, Allen’s hummingbird, Anna’s hummingbird, broad-tailed hummingbird, black-chinned hummingbird, calliope hummingbird, buff-bellied hummingbird, broad-billed hummingbird and violet-crowned hummingbird.

To track the progress of ruby-throated hummingbird migration for yourself, visit http://www.journeynorth.org to monitor their approach to our region. Ruby-throats typically arrive in our region in early April. The early date for a ruby-throated hummingbird arrival in 2018 took place on April 4. If you don’t have your feeders outdoors and waiting for them, it’s time to do so.

As always, I love to hear from readers about their first hummingbird sighting of the year. Jot down the time and date and contact me by email at ahoodedwarbler@aol.com. You can also report your sightings on Facebook at http://www.facebook.com/ahoodedwarbler. I can hardly wait for one of our favorite birds to get back. Let’s give them a hearty welcome.

American wigeon also known by name ‘baldpate’

Wigeon-TimMcCabe

Photo by Tim McCabe/U.S. Fish & Wildlife Service • This male American wigeon shows the white head patch that gives this duck its other common name of “baldpate.” In this photograph, a female wigeon rests near her mate while a male redhead, a species of diving duck, swims in the background. This duck nests in season wetlands in the American midwest.

Erwin, Tennessee, resident Pattie Rowland recently asked my help identifying some ducks she had photographed at the pond at Erwin Fishery Park. She already suspected the ducks in her photo were American wigeons, but she wanted confirmation.

The ducks were indeed wigeons, which are classified with the “dabblers” instead of the “divers,” which are two broad categories for describing the wild ducks likely to occur throughout North America. Dabblers feed mostly near the surface of the water, foraging on everything for aquatic insects to roots and tubers. The “divers,” not surprisingly, dive into the depth to pursue fish, mollusks and other aquatic prey.

“This was my first time to see them,” Pattie noted in a Facebook message. I congratulated her because I know how exciting a new observation of a bird can be.

Wigeon-RoyLowe

Photo by Roy Lowe/U.S. Fish & Wildlife Service • A male American wigeon looks quite at home swimming on a small pond. Wigeons belong to ducks that are classified as “dabblers” and “puddle ducks.”

It’s not been an exciting winter for ducks in the region. Other than some redheads and buffleheads back in November and early December at the start of the winter, the wigeons are the only wild ducks of interest that I’ve observed at the pond.

The U.S. Fish and Wildlife Service released its report this past summer on 2018 Trends in Duck Breeding Populations, based on surveys conducted in May and early June of 2018 by FWS and Canadian Wildlife Service.

Overall duck numbers in the survey area remained high, according to the report. Total populations were estimated at 41.2 million breeding ducks in the traditional survey area, 13 percent lower than last year’s estimate of 47.3 million but 17 percent above the long-term average. The projected mallard fall flight index was estimated at 11.4 million birds, down from the 2017 estimate of 12.9 million.
“The dip in the population for prairie-breeding puddle ducks is not unexpected and by no means unprecedented given that conditions on the prairies this spring were drier than last year,” said DU Chief Scientist Tom Moorman. “As a result, 2018 populations dropped accordingly. However, populations of all key species except northern pintails and scaup remain above long-term averages. This year’s breeding population decline is a reminder of the need to sustain the capacity of breeding habitats, particularly in the prairies as we go through natural variation in wetland conditions. Waterfowl populations are adapted well to short-term swings in habitat conditions, but we must continue to guard against the long-term loss of prairie breeding habitat.”

Early naturalist and artist John James Audubon painted this pair of American wigeon, a duck for which the male has earned the name “baldpate” for a distinctive white crown patch.

American wigeons, however, bucked the trend of some of the other prairie-breeding puddle ducks and showed a slight rise in overall numbers. The wigeon breeding population was estimated at 2.8 individual ducks, according to the survey. Wigeons beat their long-term average, which rests at 2.6 million.

The American wigeon can be found all over North America. Their breeding grounds stretch from Alaska across the tundras of Canada all the way to the Atlantic Ocean. American Wigeons can be found in their wintering habitats from the American Northwest to central Mexico, from the southern prairie pothole region through the Gulf Coast and from New York to the Bahamas close to the Atlantic shoreline. American wigeons are also common winter visitors to Central America, the Caribbean, northern Colombia, Trinidad and occasionally Venezuela

Wigeons are aquatic grazers and forage on grasses and sedges in wet meadows and pastures. The American wigeon’s diet has a higher proportion of plant matter than the diet of any other dabbling duck.

It’s also called the “baldpate” for the same reason our national bird is known as the “bald” eagle. A white patch on the forehead reminded early naturalists of a bald man’s head in much the same way that our national bird earned the term “bald” eagle because of its own white head. Further, the word “bald” is thought to derive from an archaic word in Middle English meaning “white patch,” from which the archaic definition “marked or steaked with white” is drawn.

The origins of the term “wigeon” are a bit murkier. According to Merriam-Webster Dictionary, the first known use of “wigeon” dates back to 1508, and other sources suggest that the term perhaps was derived from a French/Balearic term meaning “a kind of small crane.”

gadwalls-937033_1920

Photo by Coffee/Pixabay.com • Gadwalls are close relatives of American wigeon.

There are two other species of wigeons — the Eurasian wigeon of Asia and Europe and the Chiloé wigeon of South America. Wigeons belong to the Mareca genus of dabbling ducks, which also includes gadwall and falcated teal.

While female American wigeons produce a rather raspy quacking sound, wigeons more typically produce a vocalization when excited that sounds like “whew, whew, whew.”

Some ducks have become associated with certain bodies of water in the region, and the American wigeon is no exception. In addition to the pond at Erwin Fishery Park, there have been reports of American wigeons this winter from a large pond adjacent to the campus of Northeast State Community College in Elizabethton, Tennessee, as well as on the weir dam at Osceola Island Recreation Site in Bristol. Hooded mergansers have wintered in large numbers at Middlebrook Lake in Bristol. Hundreds of buffleheads have wintered at Wilbur Lake near Elizabethton, Tennessee, for decades. March and April, being periods of transition as winter changes into spring, could bring migrating ducks to the region’s ponds, lakes and rivers. Keep your eyes open and you could be surprised by what you find.

 

 

Many birds plan ahead for times of scarcity

bird-Struza

Photo by Struza/Pixabay.com • A chickadee plucks a peanut from its shell. Chickadees, like many other songbirds, often store food that they can utilize during lean times.

Ernie Marburg sent me an email last month about an article he had read on chickadees that he thought might be of interest. The article’s main focus involved the fact that chickadees are apparently capable of remembering 1,000 cache sites and retrieving food several months after having placed it in various scattered locations.

“Their memories are better than ours,” Ernie wrote. “Mine, anyway.”

Ernie also had a question for me about observations he and his wife have made at their home in Abingdon, Virginia, about birds and the practice of caching food.

“My wife and I have both observed crows taking bread (five or six pieces at a time) in their beaks and flying off and burying it in lawns among the grass,” he wrote. “We have also observed that they march through the lawn apparently looking for such food caches. Is this something that is commonly known? Are we correct in our observation of this?”

BlueJay-Dbadry

Photo by dbadry/Pixabay.com • Blue Jays often create food caches for acorns and other items. This jay is leaving a feeder with several peanuts thanks to an expandable esophagus.

Experts have indeed noticed this behavior. In fact, it’s fairly well known that crows are methodical in their approach to storing food. Crows, which belong to the corvid family that includes birds such as jays, ravens and magpies, are also highly intelligent animals. Their intelligence shows in the extra step they take after they have buried food. The crow will often take a leaf or twig and place it over the spot where the food has been buried. Experts suspect the bird takes this action to mark the spot and attract attention to the location when they return to look for the buried food.

Birds store food for convenience when they have more food than they can finish, but they also cache food in anticipation of periods such as inclement winter weather when food is likely to become scarce.

The blue jay, a relative of the American crow, is fond of acorns. The jay is so enamored of acorns — a nutrient-rich food for many birds and other animals — and so dedicated to caching acorns that the bird actually helps oak forests expand. A single jay may cache thousands of acorns each fall. Inevitably, some of the cache will be forgotten, to go uneaten and give the acorn the chance to sprout into a seedling in the spring that may grow into a mighty oak in a new stand of oaks.

The jay even has some modifications to help with the storing of food. Blue jays have a flexible esophagus that can distend and allow them to stuff multiple acorns down their throats. Caching food is hard work, so it helps reduce energy consumption if the jay can transport several acorns at a time instead of a single acorn on each trip to a cache site.

Photo by Anne773/Pixabay.com • A Carolina chickadee visits a feeder for a sunflower seed. Chickadees are a songbird that’s known for storing surplus seeds as insurance against lean times.

Now, back to chickadees for a moment. Research has shown that the brains of black-capped chickadees grow in anticipation of the need to remember where these tiny songbirds cache their sunflower seeds and other foods. The interesting finding is that only the part of the brain associated with memory grows. After all, it doesn’t do much good to store food for a rainy or snowy day if the bird promptly forgets where the food has been hidden.

natdiglib_28233_extralarge

This image illustrates an acorn woodpecker’s visit to a food cache. These woodpeckers are famous for storing acorns in dead and living trees, as well as substitutes such as telephone poles.

The acorn woodpecker might qualify as a world-class cacher of food. As the bird’s name suggests, this woodpecker loves acorns. An acorn woodpecker will devote a significant amount of its time to establishing granaries. In this case, the granaries are holes drilled in the trunks of trees (or sometimes in a telephone pole or the side of a wooden building) for the storing of acorns. Some of these trees have hundreds of holes drilled into them with each hole containing an acorn placed there by the woodpecker. The woodpeckers often use dead trees, but they also utilize living trees. Surprisingly, the holes do not seem to affect the health of the trees.

From chickadees and woodpeckers to crows and jays, birds manage to continually surprise with seemingly infinite resourcefulness.

Brief stay of Virginia’s warbler along Kingsport’s Holston River leaves birders amazed

At times, there’s nothing left to do but scratch your head and wonder. It’s a gesture many birders have been making around the Holston River in Kingsport as walks in the area along Netherland Inn Drive on the greenbelt have produced numerous warbler sightings in recent weeks.

Virginia'sWarbler-TWO

Photo by Sherrie Quillen • The Virginia’s warbler found in January in Kingsport represented the first Tennessee record for the species and one of only a few records east of the Mississippi River.

The list includes expected winter warblers such as orange-crowned, pine, and yellow-rumped, as well as such off-season puzzlers as American redstart, common yellowthroat, Northern parula, Cape May warbler and Nashville warbler; these warblers really should be wintering far to the south in locations around the Caribbean and in Central America. So far this winter, sharp-eyed birders have seen at least 12 different warbler species on the Riverfront Greenbelt. None of them have generated the level of excitement that has been produced by a small plain gray and yellow bird that is doggedly devoted to its daily routine. Birders have rushed from all parts of Tennessee, as well as from as far afield as Virginia and New Jersey, for a chance to see a visiting Virginia’s warbler, a bird that has only been observed on a handful of occasions east of the Mississippi River.

This warbler is not named for the state of Virginia. Spencer F. Baird, who first described the Virginia’s Warbler in 1860, named the species after Virginia Anderson, the wife of Dr. W. W. Anderson, who collected the first specimen in 1858 in New Mexico. Virginia’s warbler is not all that exceptional in appearance. While gray overall the bird shows a white eyering and some yellow highlights to feathers on the chest and under the tail. The bird also wags its tail, a behavior that can be helpful in identifying it.

Northeast Tennessee is outside of the expected range in the American southwest of Virginia’s warbler.

The Virginia’s warbler is a species known for showing up in some rather odd locations. Back in 2012, one of these warblers generated birding excitement around New York City when one was found in Alley Pond Park in the New York City borough of Queens. In their usual range, however, Virginia’s warblers nest in arid terrain, including open pinyon-juniper and oak woodlands in the southwestern Rocky Mountain states, which is a far cry from the banks of the Holston River in Kingsport or Queens in New York.

The Kingsport specimen pulled a vanishing act when the weather turned milder in early February. Well-known birder Rick Knight, who lives in Johnson City, Tennessee, addressed the status of the bird in a post he made to the list-serve, “TN-Bird”:

“The Virginia’s Warbler and the other unusual warblers present at Riverfront Park in Kingsport seem to wander some on warm days and then return to the water’s edge on cold days to take advantage of the milder microclimate there.” Knight went on to speculate that the bird may still be in the vicinity and will return to its usual haunts when cold temperatures return. So far, despite a mix of warm days with colder ones, the Virginia’s warbler hasn’t been seen since Feb. 2.

Virginia'sWarbler-ONE

Photo by Sherrie Quillen • The influx of birders to view the Virginia’s warbler led to other unexpected finds along the Kingsport greenbelt, including such out-of-season birds as blue-gray gnatcatchers, Nashville warbler and Northern parula. More than a few birders referred to the famous Patagonian Picnic Table Effect to describe the sightings.

Several birders who found the bird and added it to their life lists commented on the fact that so many other unexpected species were found at the same time in the same location. It wasn’t long before people began evoking the famous birding phenomenon known as the Patagonia Picnic Table Effect, which is a birding phenomenon named for a famous hotspot in southeast Arizona. The lure of a bird called the rose-throated becard at the location attracted a rush of birders to the area. More eyes resulted in more discoveries of other rare birds. In turn, the additional finds continued attracting even more birders and resulted in the discovery of even more rare bird species.

So, who first noticed the presence of the out-of-place warbler? The credit for the discovery goes to two Kingsport residents. On a post to Facebook, the two women who discovered the bird shared details of their exciting find. Bambi “Birdfinder” Fincher posted the notice of the bird’s discovery.

BGGnatcatcher

Photo by Bryan Stevens • A couple of blue-gray gnatcatchers, such as this invidiual, represented an unusual find in winter in the region. The gnatcatchers were spotted by sharp-eyed birders in their quest to observe the Virginia’s warbler in Kingsport.

“Yesterday (Saturday, Jan. 19) in the pouring rain, Sherrie Quillen and I found a Virginia’s warbler on Kingsport Birding Trail-Riverfront Greenbelt,” she wrote in a post to the Birding Kingsport Facebook page. “This is the first record of this bird in the state of Tennessee.”

Bambi explained her birding success simply. “I’m always looking! Keeps me birding!”

She also invited other birders to join her some time. “It can be pretty amazing,” she wrote. “No promises of a state record or life bird, but I can promise you that you will learn something about your surroundings and yourself.”

She earned her nickname “birdfinder” about 10 years ago when she first started birding. “I was out birding with Bill Moyle or Bill Grigsby — one of the Bill’s, anyway — and I was really ‘finding’ birds but didn’t know what they were.”

The Bills didn’t let her get discouraged. “They said, ‘That’s OK, you will learn the birds, but you are a birdfinder.’ It stuck.”

I met both Bambi and Sherrie for the first time on the day I traveled to Kingsport to try my luck at observing this warbler. Bambi quickly proved her “birdfinder” talents. Although I had to wait for about an hour for the bird to make an appearance, when it did arrive, it flew right to the spot by the river that Bambi had recommended I keep under observation. The specific spot consisted of a thin stand of privet rooted in the riverbank only a few yards from a bench located near the paved walking path. When the bird arrived, making telltale chip notes, I got my binoculars on it and enjoyed a satisfying but brief look at the bird. Birds are rarely as cooperative as this particular Virginia’s warbler turned out to be. Several other birders waiting with me also got to see the warbler at the same time. As warblers are my favorite family of birds, getting to observe this unexpected visitor has been the highlight of my birding year thus far.

In the Eastern United States, there are only a handful of warblers I haven’t yet observed. I need to see a cerulean warbler and Connecticut warbler, as well as a Kirtland’s warbler and golden-cheeked warbler. The latter two species are considered endangered and highly localized warblers occurring mostly in Michigan and Texas, respectively — two states I’ve not yet visited.

I’ll always remember my first look at a Virginia’s warbler just before noon on Jan. 28, 2019. The bird had already been present for ten days by the time I made the drive to Kingsport to try my luck. In addition, I saw many other interesting birds while waiting for my target bird to arrive. Some of the other observed birds included palm warbler, blue-gray gnatcatcher, ruby-crowned kinglets and golden-crowned kinglets.

Man saves common loon after bird makes crash landing

loon-dkbach

Photo by dkbach/Pixabay.com • The common loon is a masterful diver and swimmer, but these birds are awkward and nearly helpless on land.

An early December snowstorm had deposited a blanket of snow over the landscape, but milder temperatures quickly melted the snow on roadways when a weary — or perhaps disoriented — traveler made a crash landing.

Complete disaster was avoided thanks to the efforts of Joe McGuiness, a resident of Erwin, Tennessee, as well as an employee of the U.S. Forest Service. Joe shared the story at a recent meeting of the Elizabethton Bird Club.

Joe discovered the stranded traveler just after he finished having lunch on Dec. 6. He looked out his window and saw a “dark blob” in the driveway.loon-30901_1280

Joe recognized that the blob was actually an immature common loon. As he went to investigate, the bird tried to slide downhill on some of the recent snow.

Waterfowl like loons and grebes occasionally make landings on wet roadways. These birds mistake the dark, damp asphalt for water and don’t realize their error until it is too late.

“It probably landed on a neighborhood road by mistake,” explained Joe, who resides in the Rolling Hills residential community in Erwin. Over the years, Joe has been a magnet for some unusual birds. Several years ago, an American woodcock became a daily visitor for a spell in the community where Joe lives. Several birders got an opportunity to see that particular bird, which is usually extremely elusive and difficult to observe at close range.

loon_rescue

Photo courtesy of Joe McGuiness • When this common loon stranded itself, Erwin resident Joe McGuiness went into action, collecting the bird for transport to a nearby pond. Because of the position of their feet on their bodies, loons are almost incapable of walking on land.

Once he identified the loon, Joe still faced the challenge of rescuing it. Without human intervention, the bird would have been doomed. Loons, while so graceful and powerful in their element, are clumsy and almost helpless on land. According to loons.org, the official website for The Loon Preservation Committee, the placement of a loon’s legs at the far back of the body ensures that loons are excellent divers and swimmers. It also means that loons can not easily walk on land. This difficulty is one reason why loons nest right next to the water. At night, loons sleep over deep water, away from land, for protection from predators.

Once a loon lands on any body of water, it requires a considerably long “runway” to take off again. They sort of run along the surface of the water to gain the momentum to become airborne again. Obviously, that’s not going to happen for one of these birds if they’ve made the mistake of putting down on dry land. Fortunately, Joe realized he would need to help the loon reach water.

loon-krista-269

Photo by Krista-269/Pixabay.com • Common loons in summer breeding plumage are strikingly handsome birds that show much grace and agility in the water.

By tossing a coat over the loon, Joe managed to subdue the bird and transport it to a local pond for release. As he placed the bird at the edge of the pond, the loon surprised him and didn’t budge. Joe gave the bird a helpful nudge. In response, the bird turned and whacked him in the face with its beak. I suppose no good deed goes unpunished.

Eventually, the frightened loon moved into the water. The loon has remained on the pond recuperating for several weeks, which has allowed people to see the rescued creature.

In the northern United States and Canada, the common loon is often put forward as a symbol of the wilderness areas where it likes to reside on ponds and lakes for the summer nesting season. In Europe and Asia, the common loon is known by the more descriptive name “great northern diver.”

Common_Loon_on_Water

Photo by U.S. Fish & Wildlife Service • Common loons are quite at home in the air and on the water, but these birds are awkward if weather forces them to set down on land.

A common loon can reach a length of 3 feet. This bird’s wingspan can stretch out to almost 5 feet. They can attain a weight between 9 and 12 pounds, which is quite heavy for most birds.

All five living species of loons are members of the genus Gavia, which in addition to the common loon also includes red-throated loon, Arctic loon, Pacific loon and yellow-billed loon. All loons feed chiefly on fish.

It’s usually human behavior that puts loons at risk. For example, ingested lead fishing tackle is a leading cause of mortality for loons in New Hampshire. Joe’s encounter with a loon, and its happy ending, spotlights how people can sometimes help these beautiful birds instead of harming them.

Overwintering birds make their return to some familiar area haunts

Mergansers

Photo by Bryan Stevens • A female hooded merganser flaps her wings as another preens her feathers behind her.

Now that the warblers, hummingbirds and other birds of summer have, for the most part, departed, new arrivals have filtered into the region to take their place and prevent the winter months from seeming too bleak.

At my own home, these new arrivals have included a field sparrow — the first I’ve seen at home in several years — and a swamp sparrow. I’ve not caught sight of white-throated sparrows or dark-eyed juncos so far, but these hardy sparrows often don’t arrive until the first incidents of truly snowy weather. However, Helen Whited of Richlands, Virginia, emailed me to let me know that she saw her first dark-eyed junco of the season on Monday, Nov. 5.

Different species of waterfowl have also returned to some familiar haunts, and I’m grateful to readers who have kept me informed about some of these arrivals. Joanne Campbell of Bristol, Tennessee, posted on my Facebook page that hooded mergansers have returned to Middlebrook Lake near her home on Saturday, Nov. 3. The hooded merganser, Joanne noted, is one of her favorite birds. Brookie and Jean Potter of Elizabethton, Tennessee, reported that four male buffleheads returned to Wilbur Lake near their home on Oct. 27.

Middlebrook Lake has served as a winter home for hooded mergansers since 1987, while buffleheads have congregated on Wilbur Lake for decades. Another good location to look for buffleheads during the winter months is in the weir below South Holston Dam around the Osceola Island Recreation Area. Several hundred of these ducks have been reported in past winters at these various locations.

Although classified as sea ducks, the mergansers are more at home in river habitats. There are six closely related species in three genera: Mergus, Mergellus and Lophodytes. The latter two genera have only a single species each: the hooded merganser (Lophodytes cucullatus) and the smew (Mergellus albellus).

The typical mergansers are fish-eating waterfowl in the genus known as Mergus. The hooded merganser’s genus name of Lophodytes is derived from Greek and, roughly translated, means “crested diver.” Both male and female hooded mergansers have crests capable of being raised or lowered. Females are mostly brown, but males have a striking plumage in a pattern of brown, white and black.

Everyone has probably heard the phrase “as scarce as hen’s teeth.” It means almost exactly what you think. Birds don’t have teeth, so it’s a way to describe something exceptionally rare. It’s a characteristic that sets birds apart from other creatures, such as mammals.

There are some birds, however, that come closer to having teeth than their other beaked counterparts. Mergansers would definitely fall into that category. The mergansers are a type of duck known collectively as “sawbills,” a reference to their long, thin bills with serrated edges that help them grip prey. The “sawbills” come closer than any of our other birds in having teeth, although not in the same sense as mammals have teeth.

merganser-Bill-ALexas-fotos

Photo by Alexas-fotos/Pixabay.com • This closeup of a female common merganser shows in detail the serrated bill, which assists this duck in seizing and grasping the fish that makes up a good portion of the bird’s diet.

The other mergansers in the Mergus genus consist of four species: common merganser, Brazilian merganser, red-breasted Merganser and scaly-sided Merganser. The last of these is an endangered species with only about 5,000 birds in the worldwide population. These remaining scaly-sided mergansers are found in the border regions of China, North Korea and Russia.

While today’s birds, even mergansers, all lack teeth, that hasn’t always been the case. About 80 million years ago, a bird known as Hesperornis (“western bird”) swam the inland seas that stretched over areas from Kansas to Canada. They swam through those ancient seas because they could not fly.

The body plan of Hesperornis was similar to modern loons and mergansers. Instead of a serrated bill, however, this ancient bird had actual teeth in its long beak. Just like today’s loons and mergansers, it probably fished for its food. At almost six feet in length, however, it dwarfed our modern mergansers and loons and probably fed on larger piscine prey.

Hesperornis_Heinrich_Harder

This early 20th century illustration of Hesperornis is no longer considered scientifically accurate by scientists, but it does demonstrate one striking feature – the toothed jaws of this ancient bird.

Hooded mergansers are content to seek smaller fish. According to the website for the Ducks Unlimited organization, the hooded merganser is the smallest of the three North American mergansers. In addition to fish, hooded mergansers feed on crayfish and other crustaceans, as well as aquatic insects.

The hooded merganser prefers forested wetlands. As a cavity-nesting bird, it seeks out natural cavities in trees for nesting, although it will also accept nest boxes provided by human landlords. This duck breeds from as far north as Alaska and Canada and as far south as Louisiana and Georgia.

IMG_5909

Photo by Bryan Stevens • Hooded merganser females, or hens, have a gray-brown head and neck with a reddish-brown crest, which marks quite a contrast from the male’s appearance.

Late fall and winter are good times to see ducks in the region. Some will spend a good portion of the winter season on area lakes, rivers and ponds, while others will make only brief stops during their migration to their preferred wintering grounds. Some of the other ducks that are usually somewhat common in the region in winter include ring-necked duck and American wigeon. If you live or work near a body of water, stay alert for the comings and goings of waterfowl as winter approaches. You may be afforded an opportunity to see a hooded merganser or bufflehead for yourself.

Dark-eyed junco heralds winter’s approach and marks milestone in weekly bird musings

junco-feb9

Photo by Bryan Stevens • A dark-eyed junco, usually a harbinger of wintry weather and snowy days, shells sunflower seeds beneath a feeder.

I wrote my first column about our “feathered friends” on Sunday, Nov. 5, 1995, which means this column will soon celebrate its 23rd anniversary.

This column has appeared on a weekly basis for the last 23 years in a total of five different newspapers, and in recent years it has been syndicated to several more. The column has also been a great conduit for getting to know other people interested birds and birding. I always enjoy hearing from readers, and I hope to continue to do so in the coming years as well. Since February 2014, I’ve also been posting the column as a weekly blog on birds and birding.

I saw my first swamp sparrow of the fall on Oct. 23. Autumn’s a time when many of those so-called “little brown birds,” also known as the sparrows, return to live in the fields, gardens, yards and woodlands around our home. Two of the other anticipated arrivals are white-throated sparrows and dark-eyed juncos.

SwampSparrow-April11

Photo by Bryan Stevens • Sparrows, like this swamp sparrow, often spend the winter months in fields, woods, and wetlands, sometimes visiting feeders in our homes and gardens.

In fact, that first column I wrote back in 1995 focused on one of the region’s most prevalent winter residents— the dark-eyed junco. Experts place juncos among the varied sparrow family. All juncos are resident of the New World, ranging throughout North and Central America. Scientists are continually debating precisely how many species of junco exist, with estimates ranging from a mere three species to about a dozen species.

Some of the other juncos include the volcano junco, yellow-eyed junco, Chiapas junco, Guadalupe junco, pink-sided junco, Oregon junco and Baird’s junco, which is named in honor Spencer Fullerton Baird, a 19th century American naturalist and a former Secretary of the Smithsonian Institution.

With that introduction and with some revisions I have made through the years, here is that very first column that I ever wrote about birds.

dark-eyed-junco-Skeeze-Pixabay

…..

Of all the birds associated with winter weather, few are as symbolic as the dark-eyed junco, or “snow bird.” The junco occurs in several geographic variations.

John V. Dennis, author of “A Complete Guide to Bird Feeding,” captures the essence of the junco in the following description: “Driving winds and swirling snow do not daunt this plucky bird. The coldest winter days see the junco as lively as ever and with a joie de vivre that bolsters our sagging spirits.” The dark-eyed junco’s scientific name, hyemalis, is New Latin for “wintry,” an apt description of this bird.

dennisjl 2

Most people look forward to the spring return of some of our brilliant birds — warblers, tanagers and orioles — and I must admit that I also enjoy the arrival of these birds. The junco, in comparison to some of these species, is not in the same league. Nevertheless, the junco is handsome in its slate gray and white plumage, giving rise to the old saying “dark skies above, snow below.”

Just as neotropical migrants make long distance journeys twice a year, the junco is also a migrating species. But in Appalachia, the junco is a special type of migrant. Most people think of birds as “going south for the winter.” In a basic sense this is true. But some juncos do not undertake a long horizontal (the scientific term) migration from north to south. Instead, these birds merely move from high elevations, such as the spruce fir peaks, to the lower elevations. This type of migration is known as vertical migration. Other juncos, such as those that spend their breeding season in northern locales, do make a southern migration and, at times, even mix with the vertical migrants.

Juncos are usually in residence around my home by early November. Once they make themselves at home I can expect to play host to them until at least late April or early May of the following year. So, for at least six months, the snow bird is one of the most common and delightful feeder visitors a bird enthusiast could want.

Juncos flock to feeders where they are rather mild-mannered — except among themselves. There are definite pecking orders in a junco flock, and females are usually on the lower tiers of the hierarchy. Females can sometimes be distinguished from males because of their paler gray or even brown upper plumage.

Junco

Since juncos are primarily ground feeders, they tend to shun hanging feeders. But one winter I observed a junco that had mastered perching on a hanging “pine cone” feeder to enjoy a suet and peanut butter mixture.

Dark-eyed juncos often are content to glean the scraps other birds knock to the ground. Juncos are widespread. They visit feeders across North America. The junco is the most common species of bird to visit feeding stations. They will sample a variety of fare, but prefer such seeds as millet, cracked corn or black oil sunflower.

There’s something about winter that makes a junco’s dark and light garb an appropriate and even striking choice, particularly against a backdrop of newly fallen snow.

Junco-Carver

Of course, the real entertainment from juncos come from their frequent visits to our backyard feeders. When these birds flock to a feeder and begin a furious period of eating, I don’t even have to glance skyward or tune in the television weather forecast. I know what they know. Bad weather is on the way!

•••••

Back when I wrote that original column, juncos often returned each fall in the final days of October or first days of November. In the last few years, however, their arrival times have grown consistently later in November. At times, it takes a serious snowfall to drive these hardy birds to seek out easy fare at my feeders. I’m hoping they’ll return soon. In the meantime, if you want to share your first dark-eyed junco sighting of the fall, I’d love to hear from you. If you want to share a sighting, have a question or wish to make a comment, email ahoodedwarbler@aol.com.

Some birds expert at conjuring Halloween-style thrills and chills

nature bird cute wildlife

The  greater tit, a European relative of the Carolina chickadee, has learned to hunt and kill a species of small bat in the Hungarian mountains. • Photo by Pixabay on Pexels.com

Here’s a repost from November of 2018. The timing seems appropriate. 

My ruby-throated hummingbirds set a new record this year, lingering until Oct. 17. Although present on the morning of that date, I didn’t see any that evening. The next morning, their absence — quite notable and somewhat saddening — continued. In all likelihood, I won’t see any more ruby-throated hummingbirds until next April. I hope they arrive early.

Carolyn Baker Martin commented on the post I made on Facebook about the departure of the hummers. Carolyn noted that 2018 has been an interesting year for birds and flowers. Carolyn, who lives in Elizabethton, Tennessee, also shared a recent observation she made of a hummingbird behavior that I’ve never personally witnessed.

“I had a hummer recently in torpor,” Carolyn wrote in her post. “It sat on the feeder a long time without moving or feeding. Finally, a tail feather began to move. It fed constantly for one more day and was gone.”

Despite their small size, most hummingbirds, including the ruby-throated hummingbirds, are less frail than they appear. Torpor is a biological adaptation possessed by hummingbirds and some other creatures that lets them survive a serious cold spell. It’s not quite the same thing, but think of these tiny birds as voluntarily going into a coma when they enter torpor. Comatose or catatonic creatures are a staple of some horror and suspense films, so perhaps a look at how some birds can induce shivers along the spine is in order in view of the celebration of Halloween this week.

Image by Josep Monter Martinez from Pixabay • Bats, like birds, have the power of flight. Scientists have also learned that some unlikely birds have also developed a liking for feasting on bat brains.

The ultimate coma victim is the fabled zombie, but that’s not likely to afflict any of our feathered friends, right? Well, consider the great tits of Hungary, which are relatives of our tufted titmouse and Carolina chickadee. These birds — at least the Hungarian ones — have apparently acquired a taste for brains.

Not human brains, thankfully. The victims of these brain-hungry great tits are a species of bat — a flying creature often associated with the modern celebration of Halloween, as well as legends about vampires — that shared the habitat of these birds in the Bükk Mountains of Hungary. As it turns out, the tits only hunted bats, in this case a tiny species known as common pippistrelle, out of dire necessity.

Bat ecologists Péter Estók and Björn M. Siemers, after observing the odd behavior of the great tits during some winter seasons, conducted a study to see if great tits are consistent devourers of bats’ brains. They discovered that the birds did hunt the bats and had even learned to detect a special call the bats make as they emerge from hibernation. The ecologists conducted their study over two years and learned that the great tits teach others of their kind the special art of hunting bats. They also learned that the birds made efficient killers, dragging the bats from their roosts and cracking their skulls to get at their brains.

However, when provided with plenty of alternative food, including such favorite items as bacon and sunflower seeds, the great tits chose to eat these items rather than actively hunt bats. The researchers concluded that great tits only resort to harvesting the brains of small bats during times of scarcity during harsh winters. The bizarre story is even featured in the title of a fascinating book by Becky Crew titled “Zombie Birds, Astronaut Fish, and Other Weird Animals.”

Cassowary

Photo by lailajuliana / Pixabay.com • The southern cassowary reaches a height of more than five feet and weighs 120 pounds. The bird has a fearsome but perhaps undeserved reputation for attacks on humans.

So, if humans have nothing to fear from brain-hungry birds, are there any birds that we should fear? Some experts suggest that precautions might be in order if one expects to come into close proximity with a southern cassowary, which is the third-tallest and second-heaviest living bird, smaller only than the ostrich and emu.

The cassowary, a native of New Guinea and northeastern Australia, has developed a reputation as a fearsome bird capable of injuring or killing humans. According to ornithologist Ernest Thomas Gilliard, cassowaries deserve their reputation. In his 1958 book, “Living Birds of the World,” he explained that the second of the three toes of a cassowary is fitted with a long, straight, dagger-like claw which can sever an arm or eviscerate an abdomen with ease. According to Gilliard, there have been many records of natives being killed by this bird.

A thorough study, however, has partly exonerated the cassowary from these misdeeds. In a total of 150 documented attacks against humans, cassowaries often acted in self-defense or in defense of a nest or chicks. The only documented death of a human took place in 1926 when two teenaged brothers attacked a cassowary with clubs. The 13-year-old brother received a serious kick from the bird, but he survived. His 16-year old brother tripped and fell during the attack, which allowed the cassowary to kick him in the neck and sever the boy’s jugular vein.

So we can rest easier knowing that murderous birds that reach a height of almost six feet tall are unlikely to terrorize us should we travel to the lands down under. A more ancient relative of the cassowary, however, might have been a different story had humans lived during the same time period. Phorusrhacids, also known as “terror birds,” were a group of large carnivorous flightless birds that once had some members reign as an apex predator in South America before they went extinct around two million years ago. The tallest of the terror birds reached a height of almost 10 feet. Titanis walleri, one of the larger species, even ranged into what is now the United States in Texas and Florida.

web-terror

Terror birds were equipped with large, sharp beaks, powerful necks and sharp talons. Their beaks, which would have been used to kill prey, were attached to exceptionally large skulls. Despite their fearsome appearance, these birds probably fed on prey about the size of rabbits. Perhaps not knowing this, Hollywood has cast these birds as monsters in such films as 2016’s “Terror Birds” and 2008’s “10,000 BC.”

Besides, casting birds as the villains had already been done back in 1963 when Alfred Hitchcock released his film, “The Birds,” based loosely on a short story by Daphne du Maurier. The film, which starred some big Hollywood names such as Rod Taylor, Tippi Hedren, Jessica Tandy, Suzanne Pleshette and Veronica Cartwright, cast a whole new light on a “murder” of crows. Today, the film has achieved the status of a Hollywood classic. I guess it just goes to show that werewolves, zombies, and other Halloween monsters have nothing on our fine feathered friends.
