Hollywood, not nature, casts feathered friends in villainous light

NOTE: This is a revised version of a column that originally ran in November of 2018.

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.

Pixabay Great tits have been documented hunting, killing and then eating the brains of small bats.

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.”

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 a person comes into close proximity with a southern cassowary, which is the third-tallest and second-heaviest living bird, smaller only than the ostrich and emu.

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.

The cassowary, a native of New Guinea and northeastern Australia, has developed a reputation as a fearsome bird capable of injuring or killing humans. Cassowaries deserve their reputation, according to ornithologist Ernest Thomas Gilliard. 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.

An illustration of Gastornis (Terror Bird) on a river’s edge. Gastornis are an extinct genus of large flightless birds that lived during the late Paleocene and Eocene epochs of the Cenozoic era. They grew to a height of 6.6 feet.

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.

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.”

Regardless, the casting of birds as film 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.

There’s also the tale of the ancient Greek playwright Aeschylus, who died around 456 BC in Sicily, possibly the only known victim of a bird dropping a heavy weight on a human being. According to ancient accounts mentioned by Pliny the Elder in his “Natural History,” Aeschylus was said to have been killed by a tortoise dropped by an eagle after the bird mistook the playwright’s bald head for a stone it could use to crack open the tortoise’s shell. However, this intriguing tale is, alas, likely only a myth. Most scholars have dismissed the account as an embellished, apocryphal story.

I guess we will have to look to Hollywood’s werewolves, zombies and other supernatural monsters for our Halloween chills and thrills instead of our fine feathered friends.

Scarlet tanager, 9; Northern cardinal, 165; Rose-breasted grosbeak, 13; and indigo bunting, 9.

Some species were noteworthy in their absence. Notable misses included white-eyed vireo, blue-gray gnatcatcher, winter wren, hermit thrush and blue grosbeak.

The count was held a week later than usual due to the fall meeting of the Tennessee Ornithological Society in

Johnson City. This may have accounted for some of the misses or low numbers for some species , such as the single hummingbird. On the other hand, the later date may have contributed to finding some of the later migrants, including orange-crowned warbler and white-throated sparrow.

The count has been held on the first Saturday in October a few times previously.

Local couple comes to aid of injured hummingbird

1 Reply

Rex and Linda Mathes • Linda and Rex Mathes came to the aid of this injured hummingbird. Most ruby-throated hummingbirds, like other migratory birds, face many perils and obstacles during their migrations.

Erwin resident Linda Mathes emailed me recently to inquire about wildlife rehabilitators who might be able to help an injured ruby-throated hummingbird.

“We found a hummingbird in the backyard yesterday, alive, so brought into house and put in box,” Linda wrote. “We think its wing is damaged.”

Linda noted that she and her husband, Rex, also brought the hummingbird feeder inside.

“My husband picks it up and holds it up to feeder and it drinks,” Linda explained. “He does this several times a day.”

She added that the hummingbird regained enough strength to also sit on Rex’s finger.

“We were worried the bird would not have any nectar during the night,” she added.

The next morning, the bird still seemed fine other than for the injured wing.

“He is very perky,” Linda note. “He/she is a real fighter.”

I provided Linda with some suggestions on wildlife rehabilitaters, but she found one on her own with the help of a friend. Rex and Linda made a trip on Monday, Sept. 29, to deliver the hummingbird into the care of a licensed wildlife rehabilitation professional.

Bryan Stevens • Ruby-throated hummingbirds have usually departed from the region by early October.

“They gave me a patient number so I could call about the bird.”

When she called on the morning of Tuesday, Sept 30, she got a detailed report.

The vet had prescribed muscle relaxers for the hummingbird,” Linda said. “Her condition was listed as guarded but at least she might have a chance.”

As they were leaving the facility, someone brought in an injured chipmunk.

Linda added that there was no charge for caring for the bird but she planned to send a small donation.

I’m hopeful for the hummingbird’s recovery. Over the years, I’ve encountered several injured birds. Several of the birds stunned themselves after impacts with windows, an all-too-common hazard. Rose-breasted grosbeak and Swainson’s thrush have been among some of these. Most of the birds have recovered after a brief rest period in a shoe box covered with a towel. It’s always a relief when they can fly off under their own power.

Migration can be hazardous and arduous for our feathered friends. Birds face various hazards, including collisions with human-made structures like buildings and power lines, habitat loss and degradation, storms, disorienting light pollution and predation from other animals.

They also need to refuel to keep up their strength, and the lack of food along a migration route can deal the chances of their success a serious blow.

Even birds that cannot fly undertake migrations. For instance, flightless penguins swim hundreds or thousands of miles to reach preferred ranges for feeding or nesting. The Australian emu, a smaller relative of the ostrich, makes seasonal migrations on foot to ensure access to abundant food supplies at all seasons.

Ruby-throated hummingbirds make an awe-inspiring and non-stop crossing of the Gulf of Mexico every fall to reach their wintering grounds. Their flight across the waters of the Gulf can take these tiny birds 18 to 22 hours. Even more incredible, they make the trip in reverse in the spring when they return to their nesting grounds across the Eastern United States.

Ruby-throated hummingbirds lead relatively brief lives, which is understandable considering the perils they face and the incredible migrations they stage twice each year. The oldest known ruby-throated hummingbird was a female, according to the website All About Birds. She was at least 9 years, 2 months old when she was recaptured and rereleased in 2014 during banding operations in West Virginia.

The New World is home to about 360 species of hummingbirds. We’ve expended a lot of energy finding adjectives to provide names for all these hummingbirds. Sometimes, words fail. Mere adjectives are somewhat inadequate in providing common names for many of the world’s more hummingbirds, but that doesn’t keep us from trying to give descriptive names to each hummingbird species. For instance, we have the beautiful hummingbird of Mexico; the charming hummingbird of Costa Rica and Panama; the festive coquette of northwestern South America; and the magnificent hummingbird of the southwestern United States.

Broad-winged hawk is region’s migratory raptor

1 Reply

COURTNEY CELLEY/USFWS • A broad-winged hawk perches with a snake in its talons.

I’ve been seeing a few birds that qualify as fall migrants, but there have been some other birds in the mix, such as red-shouldered hawk.

In the last five years or so, red-shouldered hawk has become a year-round resident. But I hadn’t seen or heard one of these hawk since early summer, so I’m not sure if this individual was a resident or simply one passing through during this time of flux for our feathered friends.

Migration by its nature stirs up birds, which may pop into some unexpected places for a pit-stop on their travel route.

Other birds I’ve seen or heard recently include broad-winged hawk, Eastern wood-pewee, Northern waterthrush, hooded warbler, gray catbird, blue jay, American goldfinch, American crow, common raven, great blue heron and Eastern phoebe, as well as ruby-throated hummingbird and three woodpecker species: Downy, pileated and red-bellied.

The hawks, however, got my attention. The broad-winged hawk, known scientifically as Buteo platypterus, thrills onlookers every September by staging phenomenal migratory flights that can include hundreds or thousands of individual birds. The term “platypterus” translates from Greek as “wide winged.”

Outside of birding circles, however, the broad-winged hawk is not nearly as widely known for its migratory feats as, for example, the monarch butterfly or Eastern North America’s ruby-throated hummingbird. When time to migrate, these hawks form large flocks, which also include other raptor species. “Hawk watches” are held at some famous peaks. A Mendota Hawk Watch is conducted ever fall on Clinch Mountain near an abandoned fire tower close to Mendota, Virginia.

Larry McDaniel with the Bristol Bird Club reported that the watch this season has been productive.

“The Mendota Hawk Watch is going strong with good coverage and lots of raptors,” he wrote in a Facebook post on Sept. 19. “There have already been over 3.600 broad-wings reported and we are just now getting into the statistical peak. The show will be over by late September, so get up there while the birds are still flying.”

Other famous “hawk watch” locations in the eastern United States include Whitefish Point in Michigan and Hawk Ridge, Minnesota. Closer to home, I’ve seen sizeable flocks, or kettles, of broad-winged hawks, on occasion in the company of other raptors, on Holston Mountain and Roan Mountain.

The genus Buteo includes the broad-winged hawk’s larger kin, including red-tailed hawk, rough-legged hawk, red-shouldered hawk and ferruginous hawk. Outside the United States, raptors in the buteo genus are often known as “buzzards.” When the first European colonists came to the New World, they applied the term buzzard to both types of native vultures as well as the large raptors like Swainson’s hawk that reminded them of the ones back in Europe such as the common buzzard.

Some of the buteo species have adapted to life on islands, including the Galapagos hawk and the Hawaiian hawk. There’s an endangered sub-species of broad-winged hawk known as the Puerto Rican broad-winged hawk that resides in forests on the island of Puerto Rico.

Some of these hawks have quite descriptive names, including the white-throated hawk, gray-lined hawk, zone-tailed hawk and short-tailed hawk, as well as long-legged buzzard, jackal buzzard and red-necked buzzard.

The broad-winged hawk, like all of its kin, is a predatory bird. These medium-sized hawks prey primarily on rodents, amphibians and insects, but they will also capture and eat snakes. They take some time to prepare prey after making a capture. In the case of snakes and frogs, these hawks “skin” their victims.

Many of our hawks are resident throughout the year, but the broad-winged hawk only spends the spring and summer. Look for them now. They won’t return until late April and early May in 2026.

Use autumn to get ready for bird-feeding season

Leave a reply

Bryan Stevens • A female Northern cardinal visits a hanging platform feeder for a winter meal of sunflower seeds.

I’ve enjoyed a decent amount of activity in my yard this fall, enjoying visits from ruby-throated hummingbirds and American goldfinches as well as brown thrashers and gray catbirds. I’ve also glimpsed a few warblers. As much as I enjoy fall, crowding into my awareness is the fact that cold weather will soon be with us again.

Even that fact, however, is not totally unwelcome. Winter’s a fine season for peering through the windows at the birds that flock to feeders. So, with the winter season looming just around the corner, now might be a good time to take some steps to make your yard and feeders more attractive and welcoming to our feathered friends.

Seeing all the activity in my yard during fall migration made me want to ensure that it remains attractive for those birds that choose to eke out a living during the colder months of the year in our region.

Here are a few suggestions of things to do this fall to make your winter bird feeding more productive. It’s better to do these outdoor chores now before winter truly put a nip in the air.

• Plant native trees that bear fruit. Autumn’s a recommended planting time for many trees, so consider checking with a local nursery about the selection of such native trees as American holly, serviceberry and red mulberry. It’s always good to select trees that provide fruit at different seasons to maximize the appeal of your plantings to birds. A flock of American robins or cedar waxwings, or even a pair of Northern mockingbirds, can quickly strip berries from a holly tree when conditions turn snowy and icy.

• Build or refurbish a brush pile. Fall’s a season for pruning, so take those discarded limbs and twigs to construct a protective shelter for songbirds. Shy birds that naturally avoid open spaces can be coaxed closer to feeders by having access to a tangle of sticks and brush. A brush pile offers a degree of protection should songbirds at your feeder need to find a quick hiding place when a hawk or other predator makes an unexpected appearance.

• Evaluate feeders. The winter season brings snow, ice and a flurry of renewed interest in bird feeders, so now is the time to clean and replace feeders. The elements are not always kind on feeders, so when it becomes apparent that a feeder is in poor condition, consider replacing it with a new one. It’s also important to give feeders a thorough cleaning. Using a mild bleach solution will help disinfect them and make feeding from them safe for our feathered friends. Just be sure to rinse throughly and then dry the feeder before hanging it back out.

Photo by Bryan Stevens • Field guides are an essential tool for bird identification.

• Take some steps to increase your enjoyment of the birds coming to your feeders. Invest in a good bird identification guide or app. I am a fan of a good field guide that I can hold in my hands while thumbing through the pages, but I know that many people prefer the convenience of an app that’s accessible through their smartphone. Some popular apps would include the Audubon Bird Guide, eBird and Merlin Bird ID. Some of my recommended field guides include Peterson Field Guide to Birds of North America and The Sibley Field Guide to Birds of Eastern North America. Identifying birds congregated in the winter at a feeder is often easier than trying to track them through the green canopy during the other seasons. Of course, you’ll want to be aware that some birds wear different plumages during the winter months. The guides and apps can help with these identification challenges.

• Upgrade your optics. Place a pair of binoculars on your Christmas list. Bring the birds closer to you with a reliable pair of binoculars. It will make all the difference.

• Don’t take down the sugar water feeders just yet. Although ruby-throated hummingbirds almost all depart in early October, other species of hummingbirds normally found in the western United States have reliably made appearances in the region in October, November and other winter months. Through the years, I have seen several of these seemingly out-of-place hummingbirds. Some of them remain at their host’s feeders for a brief stay of a few days or a couple of weeks, but some of these hummingbirds have extended their stay for several months, lingering throughout the winter months before eventually departing in February or March. The big question concerns whether these hummingbirds are truly lost and out of place. The answer, based on everything I have managed to learn, is that these hummingbirds are precisely where they want to be. For still unknown reasons, some of these western hummingbirds make a migration swing through the eastern United States. One thing is certain: You won’t see one of these “strays” unless you keep out a feeder with fresh sugar water. It’s not that difficult. After all, the ants and wasps that made a nuisance of themselves during warmer temperatures are no longer active. If it gets too cold, you can always move your feeders inside at night and put back outdoors at daylight. If you do happen to attract a winter hummingbird, please let me know. I love helping to document these rare visitors.

Birds with different spring and fall looks challenge birders

Leave a reply

Photo by Bryan Stevens • A young male Rose-breasted Grosbeak visits a feeder in September of 2013. Young males resemble females but show a splash of orange on the breast that will be replaced the following spring by the familiar rosy-red patch.

My favorite season is fall. I’m always excited when birds return in the spring, but I have better luck observing fall migrants.

There’s a trade-off, however. Many birds don’t look their best by the time autumn migration rolls around. Take the male indigo bunting, for instance. This species is the only solid blue bird in the eastern United States, but it’s all an illusion — literally a trick of the light.

The indigo bunting’s feathers are not really blue; the male’s brilliant azure plumage is caused by the process of diffraction of light around the structure of the bird’s feathers. This process scatters all but the blue light, and the resulting color shifts from black to blue to turquoise as the angle of reflected light changes. In bright light, it can even look unnaturally vivid blue. In poor light, however, an indigo bunting male can appear black. Fortunately, indigo buntings have both a characteristic body shape and song, so even if the birds are not seen in their best light, they can still be recognized.

Photo by Bryan Stevens • Male indigo buntings look their best when they arrive each spring. They most over the summer, giving fall males a blotchy plumage of brown with some hints of blue remaining..

For such a bright blue bird, indigo buntings are not easy to detect. When that plumage gets mottled with brown patches in fall, these birds blend even better with their backgrounds.

The indigo bunting belongs to a genus of birds known as Passerina, which is included the family Cardinalidae, which includes birds like Northern cardinal and rose-breasted grosbeak. They are often lumped into a group known as North American buntings, although they are not closely related to such birds as snow bunting and lark bunting. The latter is even recognized as the official state bird for Colorado, a unique honor for this group of birds. The other members of the Passerina genus include lazuli bunting, varied bunting, painted bunting, rose-bellied bunting, orange-breasted bunting and blue grosbeak.

Indigo buntings linger into early October, but they also molt feathers and take on a less showy look in late summer and fall. Even the males can end up looking rather shabby compared to a spring counterpart in electric blue plumage.

The rose-breasted grosbeak, or at least adult males of the species, are birds that can take one’s breath away when observed in spring when the birds first return from their tropical wintering grounds. By fall, however, even adult males have lost some of the crisp black-and-white plumage and the rosy coloration on the breast often fades to dull orange.

In fall, the rose-breasted grosbeak migrates south to a winter range that spans central Mexico, Central America and northern South America. As they depart, many will make stops in yards with feeders to partake of offerings of sunflower seeds. So, if you didn’t get to see these showy birds in the spring, local bird enthusiasts get another chance to see them in this month and into October.

Photo by Bryan Stevens • Some of the Rose-breasted Grosbeaks migrating through this fall still retain some of their rosy color.

The male rose-breasted grosbeak gives this species it name. Males are the epitome of the birds that make their home for part of the year in the American tropics. The contrasting black and white plumage is emphasized by a triangular slash of rosy-red color on the breast. Put all those elements together and the male rose-breasted grosbeak is not a bird that would be mistaken for any other.

The female grosbeak, however, doesn’t stand out in the same way. She is much less colorful than the male. With her brown and white plumage, she is often mistaken for a large sparrow or finch. At this time of year, however, all rose-breasted grosbeaks: Adult males, adult females and young birds born this past summer can look dull. The best way to identify them is by focusing on the beak. That large, sturdy beak gives this species the other part of its name. “Gros” is a German word for big, so the name basically means “big beak.”

A fall appearance at odds with how a bird looks in the spring is also true of the scarlet tanager. The vibrant red and black spring males may look yellow or greenish-yellow once the acquire their fall and winter plumage. It’s not all that surprising. The males no longer have to impress females with their splendid coloration once the nesting season’s concluded.

The warblers, my absolute favorite family of birds, are famous for looking different in the fall. Long ago, someone coined the phrase “confusing fall warblers” since many young birds and even adult birds in fall plumage can look different than spring birds.

Photo by Bryan Stevens • The appearance of yellow-throated warblers does not change much from spring to autumn.

To identify confusing fall warblers, focus on features that remain consistent in their drabber autumn plumage, such as bill shape, leg color, tail patterns, wing bars and subtle facial markings. Learning the foraging behaviors of the various species can also be helpful.

Some of the warblers that look much different in fall includes species like magnolia warbler, Tennessee warbler, chestnut-sided warbler and Cape May warbler. Other species, such as hooded warbler, ovenbird and Northern waterthrush don’t change all that much with the seasons.

Gray catbird’s personality veers from shyness to curiosity

Leave a reply

Photo by Bryan Stevens • A gray catbird perches in a mimosa tree. These birds alternate between extreme shyness and determined curiosity.

Catbirds are experts at concealing themselves from prying eyes. This birds charcoal gray plumage blends into the shadowy sections of tangles and thickets where the bird likes to hide itself.

However, even when gray catbirds are reluctant to be seen, they’re almost eager to be heard. The catbird is extremely vocal with several calls and songs in its repertoire, including the rather faithful rendering of a fussy cat’s meow that provides this bird its common name.

This is also a bird with strong curiosity. Despite its retiring nature, curiosity often wins out, as demonstrated when I had a front porch “conversation” with a catbird on a recent morning.

The named catbird came from the fact that this mimic, related to mockingbirds and thrashers, has an uncanny vocalisation that sounds just like a cat’s meow.

Photo by Bryan Stevens • A gray catbird emerged from cover long enough to have its photo taken.

I’m not particularly good at bird imitations. I can do a decent imitation of Eastern screech owls. I’ve even succeeded at getting these small owls to call back, and I’ve incited a mob of small songbirds, convinced that a “real” owl has gotten far too close for comfort.

And I can also do a passable imitation of the catbirds “meow” vocalization, which I proceeded to spontaneously do as I stood on my front porch on a cool early September morning listening to a gray catbird hidden in the dense foliage of a blooming althea, also known as a “rose of Sharon.”

Every time the catbird meowed, I meowed back. The intervals sped up. Within a short time, the bird popped into view, the better to get a look at me. That’s when something remarkable happened. Clearly still in the bird’s view, I called back. The bird called and continued to stare at me, albeit nervously, from its perch. We continued to converse, although I’m not really sure what we were discussing. I claim to be able to imitate the bird’s language, not understand it. Despite what must have been a strong urge to dive back into cover, the bird continued to remain in the open and meow back every time I returned its meow with one of my own.

Only when I moved to go back inside did the bird plunge back into dense cover. Even as I stepped back inside the house, the catbird continued to meow.

This species is part of a family related to thrushes that are known as “mimic thrushes.” Besides its surprisingly accurate rendition of a feline, the catbird has several other common vocalizations. Despite a shy nature, they’re extremely curious. Imitating their calls or simply producing a squeaky sound will usually persuade the bird to move out of cover and search for the source of the noise.

Photo by Bryan Stevens • The gray catbird resides in Northeast Tennessee April through October, although there are a few winter records for the species. Most depart in fall, choosing to spend the winter months in more hospitable locations.

Catbirds are part of the parade of the departing birds like rose-breasted grosbeaks, scarlet tanagers, Baltimore orioles and indigo buntings that will soon wing their way south for the winter.

Because they lack the brilliant plumages of some of these other summer visitors, catbirds could often go unnoticed if not for the fact they are extremely noisy.

Although the catbird is related to thrashers and mockingbirds, scientists find them just different enough to warrant placing the gray catbird in its own genus. A relative known as the black catbird, which ranges throughout the Yucatan Peninsula of Mexico as well as northern Guatemala and northern Belize, also belongs to a genus of its own. Both catbirds are classified as “mimic thrushes,” or Mimidae, of which there are about 30 species in the New World. There is also a totally unrelated family of catbirds that ranges through Australia, Asia and parts of Africa. Some of these birds include the ochre-breasted catbird, tooth-billed catbird and spotted catbird.

The gray catbird is not as an accomplished mimic as some of its relatives, such as the Northern mockingbird. Nevertheless, experts have documented that the gray catbird can produce more than 100 different sounds. Males have motivation to constantly expand their repertoire, however, as doing so increases the likelihood of attracting a mate. They imitate other birds, but some have been recorded imitating frogs and other non-avian singers.

While not generally considered a bird to visit feeders, people have succeeded in attracting catbirds to feeders designed to offer grape jelly or orange slices. Planting fruit-bearing shrubs and trees is the best means of attracting these fascinating birds to your yard and garden. It’s also best not to clear away brush and tangles from your yard if you wish to attract catbirds. These are shy birds and will avoid areas that are too open and brightly lit.

An occasional catbird lingers in the region into the winter season, but most head out for more comfortable climates by the end of October. Enjoy this entertaining bird while you can but know they’ll return without fail next spring in April and May.

Hummingbirds, other summer birds get ready to depart

1 Reply

I always feel some reluctance and regret when I turn the calendar page from August to September.

I don’t have anything against fall – it’s my favorite season. But I know that our ruby-throated hummingbirds, which returned only five months ago in early April, will soon be departing.

It won’t be only the hummingbirds. Warblers, orioles, tanagers and other migrants will also fly south to spend the winter season somewhere more hospitable.

Most of the hummingbirds that visited our gardens over the summer are getting ready to migrate back to their winter homes in Central America.

I’m seeing only a few adult male hummingbirds with the namesake red throat. They are outnumbered by females and young hummingbirds that hatched in late spring and throughout the summer. It’s fun to watch young hummingbirds. They often have something to prove. In many ways, they’re even more feisty than adult birds.

In any given year, the numbers of hummingbirds passing thorough is going to fluctuate. Some years, these tiny flying gems will be present in good numbers on an almost daily basis. Other years, hummingbirds can become quite scarce.

I usually enjoy my best hummingbird numbers in the fall as these little birds begin their leisurely journey back south. Late August and the month of September is usually a great time to watch hummingbirds.

During August, the feeders at my home and my mother’s home saw a great deal of activity. Blooms of wildflowers and cultivated flowers also attracted them. Earlier in the summer the hummingbirds went gaga for the crocosmia blooms and the flowering bee balm. For the past month, the tube-shaped flowers of orange jewelweed has kept them coming back for more.

The New World is home to about 360 species of hummingbirds. We’ve expended many adjectives in finding names of them all. Sometimes, words fail. Mere adjectives are somewhat inadequate in providing common names for many of the world’s more hummingbirds, but that doesn’t keep us from trying to give descriptive names to each hummingbird species. For instance, we have the beautiful hummingbird of Mexico; the charming hummingbird of Costa Rica and Panama; the festive coquette of northwestern South America; and the magnificent hummingbird of the southwestern United States.

Other names are even more elaborate and occasionally outlandish, such as the white-tufted sunbeam of Peru; the violet-throated metaltail of Ecuador; the violet-throated starfrontlet of Peru and Bolivia; the hyacinth visorbearer of Brazil; and the rainbow-bearded thornbill of Colombia and Ecuador.

As for our own ruby-throated hummingbirds, wish them well as they begin that long trek back to their wintering grounds. For the young birds, this will be their first epic crossing of the Gulf of Mexico, something the species must do twice a year to get to and from their summer home in eastern North America.

Diminutive green heron flies beneath the radar but is not uncommon

Leave a reply

Photo by Bryan Stevens • A green heron captures a tadpole at a pond’s edge.

Retrieving the mail from my mailbox requires a slight trek, but there’s always something to see in the few minutes it takes to complete this task six out of seven days every week.

On a recent stroll to fetch the mail I startled a green heron from the vegetation surrounding the fish pond. The heron made a startled cry and flew to a horizontal branch in a tree adjacent to the pond.

It’s been so long since I’ve seen this small wading bird up close that I’d forgotten its diminutive nature. Although the official name is green heron, I’ve almost always referred to this species as “little green heron” or simply “little green.” It’s not completely uncalled for. After all, there’s a little blue heron. As far as my research tells me, however, there is no great green heron.

Photo by Bryan Stevens • Upcoming programs in the region will focus on topics such as songbirds, raptors and the basics of beginning birdwatching. Plan to attend one or more of the programs to learn more about birds, such as this green heron.

Green herons are not restricted to coastal areas, but it was still somewhat unexpected. I’m hoping I didn’t frighten the bird too badly and it will continue to haunt the edges of the fish pond. The vegetation around the pond makes it easy for this heron to conceal itself. The pond is also a great place for the heron to forage. There’s an abundance of some of its favorite prey, including tadpoles and dragonflies.

Green herons and other wading birds are usually quite abundant in wetlands across the country in late summer. The scientific name — Butorides virescens – of this bird comes from a mix of Middle English and Ancient Greek and roughly translates as “greenish bittern.”

There are only two other species in the genus Butorides — the lava heron, which occurs on some of the Galapagos Islands of Ecuador, and the striated heron, which is found in wetlands throughout the Old World tropics from West Africa to Japan and Australia. This heron, which is also known as the mangrove heron, also occurs in South America.

The green in the bird’s plumage appears as a dark green cap, as well as a greenish back and wings. Adult birds also have chestnut-colored neck feathers and a line of white feathers along the throat and belly. These herons often assume a hunched position, making them look smaller than they actually are.

It’s been a good summer for wading birds. In addition to the green heron, a great blue heron has been lurking in the creekand at the fish pond. Much larger than the green heron, it’s not as easy for the great blue heron to escape notice.

Other locations to look for both these herons are at the pond at Erwin Fishery Park. You’ll also want to keep alert when walking along the linear trail in Erwin. This is the time of year when interesting herons or egrets are not all that scarce.

Farm ponds in the countryside around Jonesborough, as well as wetland habitat around the town’s Persimmon Ridge Park, are also good places to look for green herons. The wetlands at Sugar Hollow Park in Bristol, Virginia, is another dependable location for seeing this small heron. Most green herons will depart in late September and early October. This small heron retreats from the United States during the winter season but returns each spring in April and May.

The green heron’s range during the nesting season includes Canada and much of the United States. Green herons will sometimes form loose nesting colonies, but at other times a pair will choose a secluded location as a nest site. The female will usually lay from three to five eggs. Snakes, raccoons and other birds such as crows and grackles are potential threats to eggs.

For the most part, the population migrates to Central and South America for the winter months. A few herons — great blue heron and black-crowned night heron — remain in the region throughout the year, even enduring the cold winter months in Northeast Tennessee, Southwest Virginia and Western North Carolina.

Green herons are probably more common than we realize. They are skilled at blending with their surroundings, but sharp eyes can find these herons around almost any body of water, whether it is pond, marsh, river, creek or lake.

Keep looking for green herons and their larger kin for the next few months. To share a sighting, ask a question or make a comment, send me an email at ahoodedwarbler@aol.com.

Birds boast phenomenal knack for long-distance travel

Leave a reply

Hans Toom/Pixabay • The blackpoll warbler has one of the more difficult and lengthy migrations of the family of warblers.

The phenomenon of migration isn’t exclusive to the neotropical migrants of the New World. Birds in other parts of the world migrate, too. Waterfowl, shorebirds and raptors are among some of the families of birds that stage impressive migrations.

Of course, I spent most of my birding within Tennessee, particularly in the Northeast Tennessee region. Since the Volunteer State has no access to the sea, it is sometimes amazing how many birds affiliated with coastal areas can be found if you know when and where to look. Fall’s a good time to scan lakeshores, river banks and the edges of farm ponds for migrating shorebirds and wading birds.

I discussed last week some of the species I hope to see this fall. Every time I see some of these migrants I am impressed by what a phenomenal feat each and every single one of these birds represents. As my mother is fond of asking: “How do they do it?”

For such relatively small creatures, many if our birds are world-class travelers. Here are a few profiles of some of these incredible migrants.

One good tern deserves another

The Arctic tern, for example, truly takes migration to extremes. This small seabird travels each year from its Arctic nesting grounds to the Antarctic region, where it spends the winter months. Put into terms of mileage, the Arctic tern can travel about 50,000 miles in a single year. For a bird with a body length of about 15 inches and a wingspan of about 28 inches, this incredible migration is an astonishing feat. These statistics permit the Arctic tern to easily lay claim to the title of champion migrant among our feathered friends. According to the website for National Geographic, Arctic terns face a serious threat from climate change. In a profile on the tern at its website, National Geographic warns that Arctic terns are projected to lose 20 to 50 percent of their habitat due to the temperature changes linked to climate change. They also face loss of habitat due to encroachment by human activities such as oil drilling.

Size matters less than we think

The ruby-throated hummingbird makes an impressive migration each year. It’s even more awesome when one considers the diminutive size of these small travelers. Just to reach the United States, these tiny birds undertake a strenuous journey. They leave their wintering grounds in Central America to return to the United States and Canada for the nesting season. Most of these tiny birds, which are barely four inches long, make a non-stop flight of more than 500 miles across the Gulf of Mexico. The journey can take almost an entire day. With the end of summer, the entire population of ruby-throated hummingbirds, increased by a new generation of young birds, makes the Gulf crossing for a second time in a year to return to the American tropics for the winter months.

Godwits, by Jove!

Shorebirds, which in North America can consist of birds ranging from turnstones and sandpipers to willets and avocets, are champion migrants. For instance, the bar-tailed godwit makes an impressive non-stop migratory flight. This shorebird nests in the United States only in parts of remote Alaska, but this godwit also ranges into Scandinavia and northern Asia. Some of these godwits make a nine-day, non-stop migratory flight that takes them from New Zealand to the Yellow Sea of China and beyond, a distance of almost 6,000 miles each way. Needless to say, since the godwits make no stops along the way, they must also go without food for the duration of their journey. The female godwit is larger than the male, but she still weighs only 12 ounces. The long-billed, long-legged bird is about 17 inches in length from the tip of the bill to its tail. That a creature so small can make such a distant, arduous trip and be the none the worse for wear is truly inspiring.

A fine kettle of hawks

Many North American raptors migrate, but the broad-winged hawk dislikes the lonely aspects of solitary travel. Instead, these hawks form large flocks, known as kettles, during migration. In autumn the majority of these raptors travel past human-staffed hawk migration observation points, which are dubbed “hawk watches,” during a brief and concentrated period of only a few weeks. Observing the phenomenon locally is possible at the Mendota Fire Tower Hawk Watch site atop Clinch Mountain at an abandoned fire tower near Mendota, Virginia. Broad-winged hawks are part of the family Accipitridae, which includes 224 species of hawks, eagles, vultures and other birds of prey. Broad-winged hawks are truly long-distance migrants. Many hawks passing over Mendota may end their migration as far south as Brazil. These hawks travel in flocks that can consist of hundreds or thousands of individuals. The birds conserve energy by soaring on thermals and mountain updrafts.

Jean Potter • Warblers, such as this male black-throated blue warbler, migrate into North America each spring to nest and retreat each fall for conditions farther south during the winter.

Traveling in stages

Most of the warblers that nest in North America retreat to Central and South America during the winter months. Few warblers, however, make as great a journey as the blackpoll warbler. Instead of migrating over land, this five-inch-long warbler undertakes a two-stage migration. The first half of the migration is a non-stop flight of about 1,500 miles. Every fall, these tiny birds fly over the ocean during this part of their migration, departing from Canada or the northern United States and not stopping until they reach various locations in the Caribbean. There they will spend some time recovering from the exhausting first half of their journey before they continue their way to such South American countries as Colombia and Venezuela.
