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

Photo by Bryan Stevens • A ruby-throated hummingbird perches at a feeder for a sip of sugar water.

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.

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.

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.

Reader from Utah shares story about pine siskin rescue

PineSiskin-Utah

A recent email reminded me that some of the birds that visit us during the winter range far beyond our yards and gardens here in Northeast Tennessee.

I received an email from Fred Bergold, a reader who resides in Utah.

“This little warbler flew into our window,” Fred explained in his email, which arrived with photos attached. “My wife picked it off the deck and held it for about half an hour.”

The kind treatment worked. “When it got its bearings back, it flew to the top of our Colorado green spruce,” Fred wrote.

Siskin-PairAtFeeders

“We feed the local wintering birds black oil sunflower seeds, which many species seem to like,’ Fred continued. “We live in Fruit Heights, Utah, just north of Salt Lake City.”

When I looked at the photos Fred provided, I realized that the bird in question wasn’t one of the warblers but a species of small finch known as a pine siskin. I replied to Fred’s email and offered a quick lesson in distinguishing pine siskins from warblers and other small songbirds.

I informed Fred that siskins usually travel in flocks and that they love feeders with sunflower seeds.

I also shared with him that I’ve gotten to travel to his home state of Utah twice since 2003. Getting to see some western species — American dipper, lazuli bunting, western tanager, violet-winged swallow — while visiting the state produced some memorable birding moments.

Sisken-Spruce

Winters, no matter where one lives, can decrease the variety of bird species one sees on a daily basis. I often find myself hoping for the excitement produced when flocks of “irruptive” finches not often seen in the area expand their range into the region. In addition to pine siskins, birds such as evening grosbeaks, purple finches, common redpolls and red crossbills represent a few of these northern finch species that occasionally stage massive migratory movements, or irruptions, into areas far outside their typical ranges.

These finches are not the only birds to stage these periodic irruptions. The website birdsource.org identifies several non-finch species — red-breasted nuthatch, Clark’s nutcracker, bohemian waxwing, black-capped chickadee and varied thrush — that undertake periodic winter irruptions. Two of these northern finches — the pine siskin and the red crossbill — are sporadic summer residents on some of the higher mountains in our region.

Siskins-OnGround

Photo by Bryan Stevens • A flock of pine siskins carpet the ground beneath some feeders as they forage for food.

These irruptions are not usually motivated by cold or severe weather. The absence of a favored food source on a bird’s normal winter range is usually a trigger for an irruption. Birds, such as pine siskins, will fly farther than normal in a quest for reliable food sources. Not surprisingly, well-stocked feeders often attract their attention.

The pine siskin belongs to a genus of birds known as Spinus, which includes three species of goldfinches and more than a dozen species of siskins, many of them native to Central and South America. Only one species — the Eurasian siskin — is found outside of the New World. Other siskins include the black-capped siskin, hooded siskin, red siskin, black siskin, Antillean siskin and Andean siskin.

GoldfinchBABE

Photo by Bryan Stevens • The American goldfinch is a relative of the pine siskin, and the two species often associate with each other at feeding stations.

Siskins often associate with American goldfinches. In shape and size, the two birds are extremely similar. Unlike goldfinches, however, siskins display extensive streaking on their back and breast. The bill of a siskin is sharp and pointed. Overall a drab brown in coloration, siskins also show some surprisingly bright yellow coloration in their wings and tails. Although sociable, individuals can display some irritable tantrums when competing for prime space at feeders.

Some people quickly discover that a large flock of pine siskins is quite a drain on the daily allotment of feed provided for backyard birds. For such small birds, they have large appetites. Siskins are also extremely tame and can often be approached quite closely. A few years ago during a particularly frigid cold snap, I succeeded in luring a pine siskin to land on my gloved hand, which held some sunflower seeds. Needless to say, it was a very memorable, intimate moment.

In addition to this unusual tameness, siskins are extremely vocal birds. These birds have a shrill trill that sounds almost mechanical to my ears. Large flocks also produce a constant twittering noise as they perch in trees or on feeders.

Next month will offer an opportunity to participate in the annual Great Backyard Bird Count, which is a free, fun, and easy event that engages bird watchers of all ages in counting birds to create a real-time snapshot of bird populations. Recording visiting birds such as pine siskins is an important component of the GBBC. Participants are asked to count birds for as little as 15 minutes (or as long as they wish) on one or more days of the four-day event and report their sightings online at birdcount.org. Anyone can take part in the Great Backyard Bird Count, from beginning bird watchers to experts, and you can participate from your backyard, or anywhere in the world. The 21st annual GBBC will be held Friday, Feb. 16, through Monday, Feb. 19, 2018. Please visit the official website at birdcount.org for more information. I’ll also focus on the GBBC more in upcoming columns, including information about activities planned at a local park.

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.

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.

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.”

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.

Bristol’s CBC records low total of species, but still makes some interesting finds

brown-headnuthatch

Just before the end of last year, 21 participants gathered to conduct the Bristol TN-VA Christmas Bird Count. Count compiler Richard Lewis noted that the CBC found 71 species and a total of 5,700 individual birds.

“This was the 63rd year the count has been run since 1956,” Lewis posted on Bristol-Birds. “It was the lowest total number of species recorded in 27 years.”

Lewis could not explain the low total of species other than to note that the area doesn’t seem to have the usual influx of wintering birds from up north. In addition, waterfowl numbers were low. “Some species are not coming as far south this year,” he added.

The best find of the count was the discovery of a new bald eagle nest on South Holston Lake. Other noteworthy species recorded were black-crowned night-heron, red-shouldered hawk, merlin and brown-headed nuthatch. The four individuals found represent a new high count for the brown-headed nuthatch on the Bristol CBC. The species had only been seen on the count three other times.

The brown-headed nuthatch is a specialist of pine woodlands throughout the southeastern United States, favoring loblolly-shortleaf pines and longleaf-slash pines. This nuthatch requires standing dead trees for nesting and roosting. They forage for food, however, on live pines. The birds are more abundant in older pine stands.

This small nuthatch is not at all common in the region, but there are some records, including other Bristol records. I’ve had much better luck finding the brown-headed nuthatch during visits to coastal South Carolina or suburban Atlanta in Georgia. In these southern locations, it can be a quite common bird.

These small birds will occasionally forage close to the ground, but they are often in the upper branches of pine trees. Their presence is often revealed by their call, which sounds amazingly like a squeeze toy. They produce their “squeaky toy” call persistently when agitated or curious. Brown-headed nuthatches often associate with mixed flocks in company with Carolina chickadees, tufted titmice, pine warblers and other small songbirds. White-breasted nuthatches and red-breasted nuthatches are more likely visitors to yards and gardens in the region.

Participants in the CBC included Ron Carrico, Rob Biller, Rack Cross, Angela Cross, Robert Hunter, Terry Hunter, Rick Knight, Roy Knispel, Cade Campbell, Larry McDaniel, Ruth Clark, Mary Clark, Randy Smith, Ron Harrington Sam Evans, Kevin Hamed, Rick Phillips, Adrianna Nelson, Michelle Sparks, Richard Lewis and Phillip Lewis.

Glade Spring CBC finds 63 species

A Christmas Bird Count is also conducted annually in Glade Spring, Virginia. This year’s Glade Spring CBC took place Dec. 27 and found a total of 63 species and 6,696 individual birds. The total and individual count both dropped slightly from last year’s count, which found 71 species and 6,891 individual birds. Twenty-three people participated on the 2018 Glade Spring CBC.

Count compiler Ron Harrington noted that one new species — a common loon found on a private pond just off Old Saltworks Road — made its Glade Spring CBC debut. Six common mergansers, a new count circle high, were found on the North Fork of the Holston River. A single common merganser was found in that same river last year for the first time.

Other highlights noted by Harrington included 48 red-tailed hawks (a new high count total), 10 hairy woodpeckers (tying the record high) and three palm warblers, which represented a new high count for this warbler species. The CBC also recorded a high count for wood ducks with seven individuals being found. Other notable finds include swamp sparrow, brown creeper, brown thrasher, loggerhead shrike, winter wren, hermit thrush, Eurasian collared dove and common grackle.
