‘Science’ article warns that people need to focus on the needs of disappearing birds

Photo by Pixabay.com • Birds are disappearing. Some populations have seen a dangerous decline. Loggerhead shrikes are declining across the continent, and the reasons are complicated but can ultimately be traced to human activity.

Imagine the sky growing dark and, looking up, you notice that the cause is not approaching storm clouds but a passage of birds — millions of individual birds, their wings darkening the skies as they pass overhead.

The early American naturalist and painter John James Audubon once described the passage of enormous flocks of passenger pigeons that blotted out the light “as by an eclipse” and described the noise of the multitude of wings “like thunder.” His observation of these flocks took place in 1813. A century later, the world’s last passenger pigeon, a species that had ranked as one of the continent’s most numerous birds, died in 1914 at the Cincinnati Zoo.

The passenger pigeon was the avian equivalent of the American bison, albeit with a more tragic outcome. Bison, also commonly called buffalo, still survive. As with the bison, we’ve had avian rescue success stories — whooping cranes, Kirtland’s warblers, bald eagles — with efforts to bring some birds back from the brink of extinction. At the same time, we’ve lost others, including the ivory-billed woodpecker, the eskimo curlew and Bachman’s warbler. Now a new study indicates that our birds may be under assault as never before.

The journal Science dropped a bombshell article recently about declining bird numbers in North America. The article’s claim that nearly 3 billion — that’s billion with a “b” — fewer wild birds exist on the continent than in 1970 is a shocking figure, but the sad fact is that the article probably doesn’t come as a complete surprise to birders or even backyard bird enthusiasts. The evidence of our own eyes and ears confirms the details of the comprehensive study reported in the pages of Science. There are fewer birds, which has been becoming painfully clear over the past few decades.

I first got into birding in 1993. Now, 26 years later, I have noticed some of the declines in just the past quarter of a century. Every autumn, the variety and numbers of migrating warblers that visit my yard has gone down.

The new study in Science focuses on the drop in sheer numbers of birds. According to most experts, the bird population in the United States and Canada was probably around 10.1 billion individual birds nearly half a century ago. That number has fallen 29 percent to about 7.2 billion birds, an alarming loss of nearly 3 billion birds just in North America.

I have personally noticed signs of this dramatic loss. Let me share some personal anecdotes. These stories don’t serve as definitive proof, but they add to my unease about the state of our feathered friends.

For one thing, I no longer host large flocks of birds at my feeders during the winter. One would expect birds to mass in sizable flocks in the vicinity of feeders during a season when resources can be scarce. In the 1990s, I hosted flocks of pine siskins and evening grosbeaks that numbered in the hundreds and dozens, respectively. At times, large flocks of American goldfinches, purple finches and house finches flocked to my feeders, too. I haven’t seen an evening grosbeak since 2001. Pine siskins still visit, but I consider myself fortunate to host a flock that numbers a dozen or more.

The sights and sounds of summer have changed, too. Two of the most dependable summer songsters used to be Northern bobwhite by day and Eastern whip-poor-will after dark. I haven’t heard a whip-poor-will at home in more than 20 years. The last time I heard a Northern bobwhite was about a decade ago. I live in a rural area that used to be fairly agricultural. The disappearances of bobwhite quail and whip-poor-wills is reported throughout the ranges of these two species.

Of course, there are always exceptions. Some birds have grown even more common in recent decades. Regionally, look at birds like great blue herons, double-crested cormorants, and cliff swallows, which have also shown an increased presence.

What killed the passenger pigeon? People did. What’s caused the precipitous drop in bird numbers since the 1970s in North America? Once again, people must shoulder most of the blame. We have destroyed or altered habitats essential for birds to thrive. We’ve paid little attention to the signals from some of these kin of the proverbial “canary in the coal mine” that something’s wrong in nature.

Yet “hope is the thing with feathers,” as the poet Emily Dickinson phrased it, and the losses are a signal to pay attention, not to panic. Birds are amazingly resilient. Birds need only the same things as humans — food, shelter, water. Well, perhaps they need one more thing. Birds require a safe and welcoming space in which to unfurl their wings and fly.

The great flocks of passenger pigeons may be no more, but there’s no reason to think our remaining birds can’t continue to soar, so long as we provide them with their essential needs and offer them a degree of protection and compassion.

Birds are not the only fall migrants sharing the skies

Photo by Bryan Stevens • Experts have documented long-distance migration flights by the Wandering Glider, a species of dragonfly.

Rhonda Eller of Chilhowie, Virginia, posted a question on my Facebook page about some dragonflies that appeared in her yard on Sept. 10.

“We have had a sudden breakout of dragonflies in our yard,” Rhonda explained. “We seldom see more than one or two at a time.”

Rhonda wondered if the dragonflies might have been drawn to her yard in pursuit of some sort of favorite insect prey. She also speculated that the recent dry conditions might have attracted the dragonflies.

I responded to her query by explaining that birds are not the only migrant in the skies at this time of year. Some dragonflies, just like birds, migrate. A species known as green darner is one that migrates. These darners are rather large, for a dragonfly, and travel in swarms. A couple of years ago I observed thousands of these dragonflies swarming over a municipal swimming pool and a nearby fish pond at a park in Erwin, Tennessee.

The WSLS Channel 10 television station out of Roanoke, Virginia, reported on swarms of dragonflies so large that they got picked up by local radar. Rhonda shared a link to the station’s story on my Facebook page.

Of course, swarms of migrating insects are bound to get the attention of predatory birds. The same day that Rhonda experienced the influx of migrating dragonflies, I witnessed dozens of common nighthawks and chimney swifts swooping through the skies over my home. With a little more attention to detail, I also noticed the dragonflies sharing the skies with these birds.

I suspect that the nighthawks were feeding on the large darners while the swifts, which are much smaller birds, focused their foraging efforts on smaller winged insects. Tom McNeil, a neighbor and fellow member of the Elizabethton Bird Club, reported seeing nighthawks and swifts, too. Tom lives on the other side of a mountain ridge that separates our homes.

Tim Morris, a Facebook friend from Australia, noted in a comment on my post about the nighthawks that his country is home a bird known as the tawny frogmouth, a relative of the common nighthawk. Tim noted that frogmouths are big birds with camouflage markings that allow them to pretend to be dead tree boughs by day. “They feed not only on insects but mice and lizards, too,” he added.

Evidence of fall migration continued the next day when I detected a small wave of warblers foraging in trees at the edge of my yard. I saw five different species — American redstart, worm-eating warbler, Cape May warbler, Blackburnian warbler and Tennessee warbler — in the space of half an hour. Of the warblers in the flock, the Blackburnian and Cape May are some of the more vibrant ones.

Photo by Bryan Stevens • While the Cape May warbler doesn’t breed locally, these warblers are fairly common spring and fall migrants in the region.

The Blackburnian warbler’s common name commemorates Anna Blackburne, an English naturalist who lived from 1726 to 1793. Her brother, Ashton, had immigrated to the United States, which made it possible for him to send his sister many specimens, especially birds. Their father, a salt merchant by trade, was also a well-respected amateur naturalist. In addition to the warbler that bears her name, Anna Blackburne also had a species of beetle named in her honor.

Both the Cape May and Tennessee warblers are named for the locations from which they were first collected. Neither of these small songbirds are closely affiliated with Cape May, New Jersey, or the Volunteer State. The Cape May warbler is also known as the “tiger warbler” for the dramatic black striping across its bright yellow breast. A green back and chestnut cheek patch make the Cape May warbler quite unlike any of its close kin. Even its scientific name — Setophaga tigrina — pays homage to the striped big cat. The term “setophaga” translates to “moth eater” and is a reference to this warbler’s intense fondness for the caterpillars known as spruce budworms that occasionally produce outbreaks in the northern spruce forests that serve as the nesting range for the Cape May warbler.

According to the website, “All About Birds,” Cape May warblers have unusually shaped tongues that allow them to sip nectar from tropical flowers during the winter months spent in Central America and the Caribbean. Their unique tongues also make it possible for them to enjoy sips of sugar water from hummingbird feeders.

Whether its dragonflies, nighthawks, warblers or hummingbirds, plenty of birds and other flying creatures will be moving through the region for the next few weeks. Now’s the time to get outdoors and look for some of these migrants.

Think of the vireos as ‘Plain Janes’ of songbirds

Photo by FotoRequest/Adobe Stock • A red-eyed vireo grasps a tree branch, a common pose for this bird that spends time concealed in the woodland canopy. The red eye can be difficult to detect unless lighting conditions are optimal for observers.

The start of migration appears to be more of a crawl than a sprint this fall, but I have picked up a few signs. For instance, I’ve been hearing the scolding sounds of red-eyed vireos from woodland edges for the past few weeks. A dedicated singer at most times, this vireo seems more likely to produce a harsh, scolding cry at this time of the year. Other hints of the steady advance of fall migration include flocks of common nighthawks and chimney swifts congregating in the skies over my home and the unmistakable croaking of common ravens from nearby ridges.

So far, I’ve seen only a few warblers, including black-throated blue warbler and hooded warbler. At a glance, vireos would appear related to the wood warblers. Research into DNA, however, has led many experts to contend that vireos are more closely related to crows and shrikes. Like the flycatcher and hummingbird families, the vireo family is exclusive to the New World. With a mere 50 species, vireos and their kin are vastly outnumbered by flycatchers and hummingbirds. The majority of vireos resides in the tropics, but about a dozen species nest in the United States.

In East Tennessee Southwest Virginia and Western North Carolina, vireos resident during the summer months include red-eyed vireo, white-eyed vireo, blue-headed vireo, yellow-throated vireo and warbling vireo. Most people are likely unaware of vireos. Although not uncommon, these birds are more frequently heard than seen. They spend much of their time in the forest canopy or in dense brush. When singing, they can remain at a perch, unmoving, for long periods of time.

Photo by Jean Potter • A red-eyed vireo sits on its carefully woven nest among a canopy of leaves.

The loud scolding calls of red-eyed vireos often heard this time of year are given apparently when the vireo is alarmed or irritated. This scolding vocalization is quite unlike the usual ones produced by this bird. First and foremost, the call is louder than one would think could be produced by a bird that is only about six inches long. During the summer season, the red-eyed vireo is also one of the most persistent of singing songbirds. Another common name for the red-eyed vireo is “preacher bird,” so called because of its tendency to unceasingly deliver its song.
The red-eyed vireo is still considered one of eastern North America’s most common summer breeding birds. At one time, the red-eyed vireo was probably the most common breeding bird in eastern woodlands. That, sadly, is no longer the case. Red-eyed vireos are olive-green above and clean white below. These birds show a distinctive head pattern consisting of a gray crown and white eyebrow stripe bordered above and below by black lines. Adults also have the red eyes that give this particular vireo its common name. The term “vireo,” originating in Latin, can be translated into English as “green bird.” It’s an apt description, as many of these small birds are primarily dull green in coloration. Consider the vireos the “Plain Janes” of songbirds.

Other vireos that can be found in the United States, for at least part of the year, include Philadelphia vireo, plumbeous vireo and Cassin’s vireo. A specialty of Florida is the black-whiskered vireo, while the black-capped vireo is an endangered species found in Texas. Two others, Bell’s vireo and gray vireo, are identified as species of concern on the Audubon Watchlist.

Many species of vireo are also found in the islands of the Caribbean, including Jamaican vireo, Cuban vireo and Puerto Rican Vireo. The thick-billed vireo can be found in the Bahamas, which were recently pulverized by Hurricane Dorian. The thick-billed vireo is very similar to the white-eyed vireo, which is a summer resident in our region.

My only birding outside of the United States took place in the Bahamas 20 years ago. My highlights included two hummingbirds — Bahama woodstar and Cuban emerald — as well as bananaquits, black-faced grassquit, Western spindalis, Cuban pewee and other interesting species. I didn’t see a thick-billed vireo, but I did get my first-ever look at a Cape May warbler. I was visiting the Bahamas in January of 1999, which proved a fortunate time since many warblers migrate to these islands for the cold months. I’m hopeful that both people and birds on the islands Abaco and Grand Bahama and smaller islands most affected by the monster storm are able to recover soon.

Some of the more colorful common names for vireos include the dwarf vireo, golden vireo and yellow-winged vireo.  In Central and South America, the vireo family expands to include many birds with common names such as shrike-vireo, greenlet and peppershrike. Some of the varied species include lemon-chested greenlet, green shrike-vireo and the black-bellied peppershrike.

I still focus most of my birding efforts on warblers in the autumn, but vireos are always a pleasant diversion when the colorful warblers make themselves scarce.

Hooded warbler and its kin bring tropical splash to area woodlands

Photo by Jean Potter • A male hooded warbler flits through the foliage of a rhododendron thicket.

I came away from a recent program on bird migration given by Kenn and Kimberly Kaufman learning a few new nuggets of information about warblers, which are one of my favorite bird families. The Kaufmans, well-known birders and activists on the behalf of birds, spoke Saturday, Aug. 31, on the topic of bird migration during the evening program at the Roan Mountain Fall Naturalists Rally. They confirmed some things I have always suspected to be true about fall migration in the region. For instance, warbler migration in the Southern Appalachians is indeed often more productive in the fall than in the spring. The Kaufmans also noted that fall migration takes place at a more leisurely pace for most of the migrating warblers. They even pointed out that some of the warblers, such as magnolia warbler and Tennessee warbler, which are uncommon fall migrants at their home in Ohio, are actually quite common in East Tennessee.

Hooded warblers nest in the woodlands around my home. So, from the time my favorite warbler returns in April until the last individual departs in October, I enjoy regular glimpses of this colorful and interesting bird. Like all warblers, the hooded warbler is quite energetic, dashing after tiny insects in the branches of shrubs and trees. Hooded warblers often forage close to the ground, which makes observing them easier.

Every time I behold a hooded warbler, I marvel at the bird’s exquisite appearance. The gold and green feathers seem to glow brightly in the dim light of the shadowy thickets of rhododendron they prefer to inhabit. The black hood and bib surrounding the male’s yellow face stands out by virtue of its stark contrast from the brighter feathers. Large coal-black eyes complete the effect. The appearance of the male bird provides this species with its common name. The female has an identical yellow-green coloration as the male, although she is slightly more drab. She lacks the black hood and bib, although older females may acquire some dark plumage on the head and around the face. Both sexes also show white tail feathers that they constantly fan and flick as they move about in thick vegetation and shrubbery.

Photo by Bryan Stevens  • Only males show the well-formed black hood and bib that gives the hooded warbler its common name.

I know that every migrant passing through my yard at this time of year is making its way southward, and it will likely be another five to six months before I again see any of my favorite songbirds. The hooded warbler will make itself at home in the forests of Mexico, as well as in Belize, Costa Rica and other Central American nations, throughout the winter season. Most hooded warblers begin returning to their winter haunts as early as mid-September, but lingering individuals continue to entertain birders in the United States throughout October.

Like many of the ruby-throated hummingbirds that make their home in the United States for the summer, the hooded warbler’s fall migration takes it across the vast open waters of the Gulf of Mexico, crossing to the Yucatan and then dispersing from there to various points in Central America. That birds as small as hummingbirds and warblers make this incredible migration twice yearly is one of nature’s most phenomenal feats of endurance. In their presentation, the Kaufmans explained that these tiny birds put on incredible fat reserves to help fuel their efforts.

The warblers, also known as wood-warblers, are an exclusively New World family of birds, numbering approximately 116 species. About 50 of these species of warblers make their home in the eastern United States and Canada for the spring and summer, departing in the fall and returning to tropical wintering grounds. Some of them are extremely bright and colorful birds. The hooded warbler would have to be included among the more brightly colored warblers.

Other colorful warblers that share similar tastes in range and habitat with the hooded warbler include the American redstart, black-throated blue warbler and black-throated green warbler.

While some of the neotropical migrants that venture into North America boast even brighter kin in the tropics, we need not feel cheated with the warblers that make their home in the United States for half of the year. Some of their relatives are beautiful birds, including the white-faced whitestart, golden-bellied warbler, three-striped warbler and rose-breasted chat, but few can really hold a candle to their relatives that venture north and brighten our lives.

The warblers are, in short, an incredible family of birds. I’ve seen all but a handful of the species that reside for part of the year in the eastern United States. I still want to see a Connecticut warbler and cerulean warbler, as well as the endangered Kirtland’s warbler of Michigan and the golden-cheeked warbler of Texas. I’ll miss the warblers once fall migration has run its course. For those months they are here, the warblers belong to us. They seem like “our” birds. They’re only on loan, though. Our winter birds will offer some compensation in their absence, but I’ll be impatiently awaiting that flash of gold from the recesses of a rhododendron thicket next April.

Gray catbirds require some gentle coaxing to give up shy habits

The gray catbird is a baffling bird with a personality that runs the gamut from introverted to extroverted, sometimes depending on the season and at other times seemingly just on a whim. With some gentle persuasion, however, people can gain a catbird’s trust and develop a fun friendship with these clever songbirds.

One summer, all I needed to do to win over the catbirds was to offer some less-than-perfect strawberries and blueberries. A few blemishes on the fruit didn’t bother the resident catbirds at all, and they soon became accustomed to receiving such treats.

Your first introduction to the catbird is likely going to occur when you hear what sounds like an irritable feline hiding in a hedge, thicket or dense shrub. Upon closer examination, you may get a glimpse of a charcoal gray bird roughly the shape of a Northern mockingbird but smaller. A black cap and a patch of rusty-red feathers under the tail are the only exceptions to this bird’s overall gray plumage.

Photo by Bryan Stevens A curious Gray Catbird peeks from dense cover. Attendees at the fall rally can look for catbirds and other species at any of the offered bird hikes.

Catbirds are experts at concealing themselves from prying eyes. The gray plumage blends into the shadowy sections of the 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.

They’re 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 their 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.

Catbirds are part of the parade of returning birds each spring that includes species like rose-breasted grosbeaks, scarlet tanagers, Baltimore orioles and indigo buntings, but because they lack the brilliant plumages of these other birds their arrival would probably go unnoticed if not for the fact they are extremely noisy for the first few weeks they are back. Then they go silent again and remain quieter as they take up the serious business of raising young.

However, in a mood that appears to swing with the seasons, gray catbirds emerge again in late summer and early fall when they feast on such fruit as elderberries and wild cherries while making their whiny cacophony of calls from any tangle or thicket where they happen to be.

The catbird belongs to the genus Dumetella. The name is based upon the Latin term dūmus, which roughly translated means “thorny thicket.” Dumetella, in turn, means “dweller in the thornbushes” or “small bird of the thornbushes.” It’s a rather apt description for a bird fond of habitats often dominated by thorny vegetation. Older common names for the gray catbird included cat thrush and slate-colored mockingbird.

They are related to thrashers and mockingbirds, but 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 a totally unrelated family of catbirds that ranges through Australia, Asia and parts of Africa.

The gray catbird is not as an accomplished mimic as some of its relatives, such as the Northern mockingbird. 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.

 

Some birds stand out from the flock with their amazing migratory feats

Photo by jasonjdking/Pixabay.com • The bobolink is also known as the “rice bird” for its tendency to feed on cultivate grains such as rice. Even the bird’s scientific name, oryzivorus, means “rice eating” and refers to this bird’s appetite for many of the same grains consumed by humans. This small songbird also undertakes yearly migration flights equalling more than 12,400 miles.

The peak of fall migration is approaching. Birds of all species are winging their way southward ahead of the months of cold and scarcity. September and October are months of flux and transition. Like a bear fattening for hibernation, I gorge on sightings of warblers, hummingbirds, tanagers and other favorites, knowing that I won’t be seeing many of these birds again until next spring. Their memories will sustain me, as will my feeders, which will still bring plenty of colorful and entertaining birds into my yard even in times of snow and ice.
Bird migration at any season is a spectacle. Many of the birds that nested in mountain hollows or vegetation-choked wetlands will winter in Central and South America, the Caribbean or other distant but warmer destinations. The following snapshots of fall’s bird migration capture the phenomenon’s drama.

Bobolink
The bobolink is a small bird in the family of blackbirds, which includes grackles, orioles and cowbirds. Nesting across North America during the summer, bobolinks retreat to South America for the winter. These small birds undertake amazing migrations, making a round-trip of about 12,400 miles to regions south of the equator in Bolivia, Paraguay and Argentina each fall. Come spring, they make the trip again, but in a northerly direction.
According to the website All About Birds, migrating bobolinks orient themselves with the earth’s magnetic field. These small birds are able to accomplish this feat due to iron oxide in bristles of its nasal cavity and in tissues around the olfactory bulb and nerve. Bobolinks also use the stars scattered across the night sky to guide their migratory flights. Capable of living as long as nine years, a long-lived bobolink will rack up some serious miles simply migrating to its nesting grounds and back to its wintering habitat each year.

Bar-tailed godwit
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.

Broad-winged hawk
Many North American raptors migrate, but the broad-winged hawk dislikes the lonely aspects of solitary travel. Instead, these hawks form large flocks during migration, and 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.

Photo by Bryan Stevens • Warblers, such as this American redstart, stage impressive migratory flights. The blackpoll warbler makes an incredibly arduous journey for a bird that is less than five inches long.

Blackpoll warbler
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. Once again, during the time they spend flying over open ocean, these tiny warblers do not feed.

Wading birds topic for program
I’ll be presenting a program on herons, egrets and other wading birds at the September meeting of the Elizabethton Bird Club. The meeting will be held at 7 p.m. Tuesday, Sept. 6, at the Elizabethton campus of Northeast State Community College, 386 Highway 91. The meeting will be held on the second floor in Room 208. The free program is open to the public and will follow a brief business meeting.

Readers with questions are welcome to email me at ahoodedwarbler@aol.com or send a friend request on Facebook at facebook.com/ahoodedwarbler. I also love to receive comments and hear about bird observations.

Long-running Elizabethton Summer Bird Count finds 115 species

The Elizabethton Bird Club holds two summer bird counts to supplement other bird population monitoring efforts on the birdlife of Tennessee.

This count focuses exclusively on locations within Carter County and was held Saturday, June 9, with 16 observers in five parties plus two yard watchers. A total of 115 species was found, which is slightly above the average of 113 per count. The all-time high was 123 species in 2017. Several species restricted to the higher elevations of East Tennessee were found.

The count yielded some surprises and highlights, including the following:

A single Northern bobwhite represented a species that has been increasingly difficult to find in the area.

Photo by Bryan Stevens • Great egret, seen here among cypress trees, made the count for the first time this year.

A couple of birds made their debut appearance on this count, including great egret and fish crow, which is expanding its range rapidly in the region.

Other good finds included ruffed grouse, sharp-shinned hawk, American woodcock, Eurasian collared-dove, yellow-bellied sapsucker, alder flycatcher, least flycatcher, common raven, red-breasted nuthatch, brown creeper, winter wren, golden-crowned kinglet, hermit thrush, grasshopper sparrow, rose-breasted grosbeak, purple finch and pine siskin.

Photo by Bryan Stevens • Hermit thrush, pictured here, is an uncommon summer nesting bird at high elevations.

The count also found 20 species of warblers, including golden-winged, Swainson’s, magnolia, Blackburnian and yellow-rumped.

Of course, there are always unexpected misses. Birds usually found on summer counts but missed this year included green heron, yellow-crowned night-heron, bald eagle, great horned owl, white-eyed vireo, warbling vireo, purple martin, Kentucky warbler, prairie Warbler and vesper sparrow.

The count total follows:

Canada goose, 91; wood duck, 7; Mallard, 78; Northern bobwhite, 1; ruffed grouse, 2; wild turkey, 35; great blue heron, 42; and great egret, 1.

Black vulture, 2; turkey vulture, 58; sharp-shinned hawk, 1; Cooper’s hawk, 3; broad-winged hawk, 1; red-tailed hawk, 10; American kestrel, 1.

Killdeer, 4; American woodcock, 1; rock pigeon, 69; Eurasian collared-dove, 3; mourning dove, 171; and yellow-billed cuckoo, 3.

Eastern screech-owl, 2; barred owl, 1; chuck-will’s widow, 3; whip-poor-will, chimney swift, 46; ruby-throated hummingbird, 35; and belted kingfisher, 10.

Red-bellied woodpecker, 15; yellow-bellied sapsucker, 3; downy woodpecker, 15; hairy woodpecker, 1; Northern flicker, 9; and pileated woodpecker, 14.
