The 83rd consecutive Elizabethton Christmas Bird Count was held Saturday, Dec. 20, 2025. Twenty-four observers participated in seven parties found a total of 73 species, plus an additional species found during count week.

Compiler Rick Knight noted that the annual survey benefitted from good weather with a temperature range from 23 to 66 degrees coupled with clear and calm conditions.
The species total is right on the recent 30-year average for this CBC. The all-time high for the Elizabethton CBC was 85 species in 2017.

The list:
Canada goose, 372; mallard, 81; redhead, 3; ring-necked duck, 17; greater scaup, 2; lesser scaup, 1; bufflehead, 109; and hooded merganser, 26.

Wild turkey, 18; pied-billed grebe, 10; horned grebe, 14; rock pigeon, 208; mourning dove, 72; killdeer, 3; Wilson’s snipe, 7; ring-billed gull, 3; common loon, 1; and great blue heron, 11.

Black vulture, 26; turkey vulture, 131; sharp-shinned hawk, 1; Cooper’s hawk, 2; bald eagle, 4; red-shouldered hawk, 1; red-tailed hawk, 14; Eastern screech owl, 5; and great horned owl, 2.

Belted kingfisher, 17; red-bellied woodpecker, 28; yellow-bellied sapsucker, 19; downy woodpecker, 15; hairy woodpecker, 4; Northern flicker, 27; pileated woodpecker, 15; American kestrel, 14; and Eastern phoebe, 13.

White-eyed vireo, 1; blue jay, 130; American crow, 343; common raven, 9; Carolina chickadee, 101; tufted titmouse, 66; ruby-crowned kinglet, 11; golden-crowned Kinglet, 24; and cedar waxwing, 18.

White-breasted nuthatch, 29; brown creeper, 1; Carolina wren, 74; and winter wren, 11.

Brown thrasher, 1; Northern mockingbird, 58; Eurasian starling, 1058; Eastern bluebird, 117; hermit thrush, 8; and American robin, 236.

House sparrow, 28; house finch, 135; purple finch, 4; American goldfinch, 74; and pine siskin. The siskin was listed as a count week find. Birds seen within the same count circle but outside of the specific count day are noted as “count week” birds and still tallied with the species found on the actual count day.

Chipping sparrow, 1; field sparrow, 20; fox sparrow, 1; dark-eyed junco, 24; white-throated sparrow, 87; Savannah sparrow, 1; song sparrow, 83; Swamp Sparrow, 3; and
Eastern towhee, 14.

Eastern meadowlark, 67; common grackle, 1; pine warbler, 3; yellow-rumped warbler, 55; and Northern cardinal, 102.

Knight singled out the white-eyed vireo as a species worthy of elaboration. The vireo was seen in Hampton at the watershed trail among a stand of pines. It was the third instance for this species on this particular CBC; white-eyed vireos were also seen in 1997 and 2001.

Notable misses, according to Knight, included barred owl, red-breasted nuthatch and white-crowned sparrow.

Black-throated blue warbler graces cover of club’s 2026 calendar

Leave a reply

The front cover of this year’s Elizabethton Bird Club calendar features a gorgeous photo of a black-throated blue warbler taken by club members David and Connie Irick.

Avoid the crowded hassle of Black Friday and get a jumpstart on your shopping list with a gift all bird lovers will enjoy for 365 days.

The Lee and Lois Herndon Chapter of Tennessee Ornithological Society, also known as the Elizabethton Bird Club, has produced its annual calendar featuring bird photographs by its members and friends of the organization.

These calendars make wonderful Christmas gifts and stocking stuffers. This year’s front cover features a gorgeous photo of a black-throated blue warbler taken by club members David and Connie Irick.

The couple recently presented a program for the local bird club that focused heavily on the warblers they saw and photographed during a visit to Magee Marsh, a 2,000-acre wildlife area located in Oak Harbor, Ohio, situated on the southern shore of Lake Erie.

During the program, David Irick admitted that before he began to pursue birding as an interest, he wasn’t even aware of the existence of warblers. Now, he and his wife are hooked on this enchanting family of colorful and energetic songbirds.

The black-throated blue warbler gracing the calendar’s cover was photographed on Holston Mountain. Male black-throated blue warblers nesting in the Appalachian Mountains have black streaks on their backs, not solid blue like other populations, according to a profile on the species located at the website for Tennessee Wildlife Resources Agency.

Black-throated Blue Warblers are among the birds than can often be found at Hampton Creek Cove during a Spring Rally.

Female black-throated blue warblers are extremely different in appearance from males. Scientists call such dramatic physical appearance differences “sexual dimorphism.” Among the warblers, this species provides the most striking example of sexual dimorphism. The male and female do share one identifying mark — a white square near the outer edge of the middle of each wing. This square is usually more pronounced in the male, but it stands out enough that it helps distinguish the female black-throated blue from similar dull-plumaged birds such as vireos.

The radical differences in appearance of male and female black-throated blues even fooled some experts, according to the TWRA profile on the species.

The “Father of American Ornithology,” Alexander Wilson (1766-1813), first described the female black-throated blue warbler, he thought it was a separate species and named it the pine swamp warbler. Several years later, when artist John James Audubon painted this bird from specimens he collected in the Great Pine Swamp of Pennsylvania, he called the species by the same name.

Learn more about warblers and other birds with a purchase of the club’s 2026 calendar. More photographs by the Iricks, as well as other members and friends of the club, grace the inside pages of the calendar. The month of July features an amazing photo of a bald eagle and November is graced by wild turkeys.

The inside pages of the professionally-produced calendar feature dozens more full-color photographs and an informative and educational grid. These calendars sell for $15 plus $2.50 for shipping. All sales help the club fund birding programs, public park feeders, conservation efforts and other bird- and nature-related activities in upper Northeast Tennessee.

Dark-eyed juncos deserving of affectionate ‘snowbirds’ nickname

Leave a reply

Photo by Bryan Stevens Dark-eyed juncos are winter residents in the region.

As I mentioned in last week’s column, I published my first “Feathered Friends” on Sunday, Nov. 5, 1995.

In celebration of that milestone, here’s that first column with a few revisions that have been added over the years.

•••

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.

The cover of the classic “A Complete Guide to Bird Feeding” by John V. Dennis.

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.

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.

Photo by Bryan Stevens • Dark-eyed junco nests on high mountain slopes during the summer month. This dark-eyed junco was photographed at Carver’s Gap on Roan Mountain during the summer nesting season.

During the summer months, a visit to higher elevations mountaintops is almost guaranteed to produce sightings of dark-eyed juncos. Juncos may nest as many as three times in a season. A female junco usually lays three to six eggs for each nest, which she constructs without any assistance from her mate.

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.

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.

Photo by Ken Thomas • A dark-eyed junco perches on some bare branches on a winter’s day.

Dark-eyed juncos, widespread across North America, readily visit feeder but are often content to glean the scraps other birds knock to the ground. 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.

The juncos are a small branch of the sparrow clan. Some of the other juncos include the endangered Guadalupe junco, yellow-eyed junco, Baird’s junco and volcano junco.

The last one on the list is endemic to the Talamancan montane forests of Costa Rica and western Panama.

The endangered Guadalupe junco is confined to an island. Recent efforts to eliminate feral goats and cats from the island have shown some positive results for this species.

Baird’s junco is named for Spencer Fullerton Baird, an American ornithologist and naturalist. Baird served as secretary for the Smithsonian Institution from 1878 until his death in 1887. He greatly expanded the natural history collections of the Smithsonian from 6,000 specimens in 1850 to over two million by the time of his death.

I hope you’ve enjoyed this introduction to juncos. 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.

Of course, the real entertainment value of juncos comes from their frequent visits to our backyard feeders. When these birds flock to a feeder and begin a frenzied bout of feeding, 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!

••••

I’ve not seen the first junco of the season, but I have observed some other late-autumn migrants, including ruby-crowned kinglets and a swamp sparrow.

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.

Why do owls give a hoot? For many reasons

Leave a reply

Dave Menke/USFWS Great horned owls, such as this individual, are effective predators after dark.

As September slid into October, the evening serenades began. At first, they consisted of a pair of Eastern screech-owls calling from the surrounding woodlands. On Oct. 2, the low hoots of a great horned owl joined the wailing calls of the two screech-owls.

I’ve gotten into the habit of 10-minute walks in the evening after dinner, and I posted about the owls on my Facebook account.

Several friends responded, including Tom McNeil, a fellow birders and an fellow alumna of Hampton High School.

“We’ve been hearing a pair (of great horned owls) hooting up on the ridge between you and us,” Tom wrote. “We also had a barred owl calling a few weeks ago, which was only the second time ever.”

Tom and his wife, Cathy, reside in the Piney Grove community of Hampton. As he indicated, only a steep mountain ridge separates his property from mine.

That ridge is a magnet for birds, ranging from pileated woodpeckers and wild turkeys to warblers, vireos, tanagers, flycatchers and many other songbirds. The bird population changes with the seasons, but there’s always a diversity of birds making their home on those wooded slopes.

Linda Cauley also responded to my Facebook post, sharing that she also had recently heard a great horned owl.

Larry A. Woodward/USFWS Eastern screech-owl chicks peer from the tree cavity that served as their first home.

Kaylynn Sanford Wilster has also been hearing a great horned owl. “First great horned owl I’ve had here in forever it seems like,” she wrote. “I think there’s just one but I’m not sure.”

Joanne Campbell commented on my post.

“We had a big hoot owl right outside our door last week,” Joanne wrote. “Closest I’ve ever been to one.”

I’d been surprised to hear screech-owls, which are considerably smaller than a great horned owl, calling at the same time as their larger kin. Great horned owls are not finicky and will dine on any smaller creature they can seize in their strong talons. I’d heard that smaller owls usually go silent in the presence of this large nocturnal predator.

Of course, the screech-owls were relatively close to my home while the great horned owl’s calls were notably distant. Perhaps they felt that enough space existed between them to ease any worries.

I also got to wondering why owls are so vocal. A little research came up with some answers.

First, it’s important to note that Eastern screech-owls produce different vocalizations for various purposes. One of my favorites is the “whinny,” a descending call that is, apparently, a territorial display to inform other owls that they have claimed a territory as their own.

At this time of the year, juvenile screech-owls are also striking out on their own away from parental care. These young owls deploy the whinny to establish their own territories. They will need a well-defined territory to ensure they can find enough prey during the lean, cold winter months.

The whinny itself is of short duration, lasting only a couple of seconds. Screech-owls also produce other sounds, which have been described as hoots, barks and squeal.

Another common screech-owl vocalization is an even-pitched trill, often called a “bounce song” or tremolo. I can do a decent job imitating this sound, and I’ve often stirred up songbirds by doing so. A flock will sometimes materialize as if from thin air, as the members of the flock scold and search for the owl. It’s a good way to draw some curious birds closer for observation.

Bryan Stevens Lucy, a rehabilitated owl, helps programmers at Brookgreen Gardens provide educational programs about owls to the public.

Great horned owls, or “hoot owls” as they are widely known, also produce their low, nocturnal calls for many of the same reasons as screech-owls do. These large owls hoot to communicate, with the most common reasons being to define and defend territory, locate and attract a mate during breeding season and stay in contact with their young. Hooting also helps them establish boundaries with other owls and signals their presence, making their calls particularly energetic and frequent in the autumn and winter months when territories are being set up.

Pairs of great horned owls will hoot together as part of their courtship to strengthen their bond. A female owl’s voice is notably higher in pitch than the male’s, according to the website All About Birds. I’m hoping I will soon hear the duet that Tom and Cathy are enjoying on the other side of the ridge. So far, I’ve only detected the one great horned owl. I have heard these mesmerizing duets in the past, however. Listening can produce shivers down the spine. Of course, that is also helped by the fact they most often hoot on evenings once the weather had become more chilly.

The days are shorter, nights are longer, so now is a great time to get familiar with the owls. It can be as easy as stepping onto the front porch and listening.

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.

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

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.

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.

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.

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.

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.
