Several different species of hawks make their home in region

1 Reply

Photo by Bryan Stevens • This captive red-shouldered hawk was rehabilitated after suffering an injury and now works in an educational program at Brookgreen Gardens in South Carolina to teach the public about raptors, other birds, and various types of wildlife.

In recent weeks, I’ve enjoyed some observations of the region’s larger raptors, including red-tailed hawks and red-shouldered hawks.

Anyone who travels along the region’s Interstate Highway System has probably noticed hawks perched in trees or on utility lines adjacent to the roadway. The section of Interstate 26 that runs between Unicoi and Johnson City is often a productive area for keeping alert for raptors. The raptor I have most often observed along this stretch of road is the Red-tailed Hawk, although I have also observed Cooper’s Hawk, Sharp-shinned Hawk, and American Kestrel. In the time of spring and fall migration, it’s also possible to observe Broad-winged Hawks.

The Red-tailed Hawk is named for its prominent red tail. However, only adults show the characteristic red tail. The affinity for Red-tailed Hawks for roadsides is a double-edged sword. Viewing a large hawk from your car is an easy way to watch birds. For inexperienced or careless raptors, however, roadside living is often rife with the chance for a collision with a car or truck. The Red-tailed Hawk, which prefers open countryside, is attracted to the margins of roads and highways because these locations also attract their favorite prey, which includes rodents like rats, squirrels and mice and other small mammals such as rabbits.

Human behavior contributes to some of the problems that hawks encounter in the zone that brings them too close for comfort to motorized vehicles. When people toss trash from a car, the scent of the litter will lure curious and hungry rodents. In turn, hunting hawks are brought to the edges of roads in search of their preferred prey, increasing the likelihood of colliding with automobiles.

In recent days, I have also noticed a Red-shouldered Hawk lurking among the branches of the large weeping willow next to the fish pond. The Red-shoulder Hawk typically prefers wetland habitats and is less likely to haunt roadsides. According to a factsheet published by the New York State Department of Environmental Conservation, this raptor breeds in moist woodlands, riverine forests, the borders of swamps, open pine woods and similar habitats. Nesting almost always occurs near water, such as a swamp, river or pond.

The Red-shouldered Hawk produces a distinctive, piercing whistle that reminds me of the shrill call of a Killdeer. The visiting Red-shouldered Hawk has been silent so far, perhaps not wishing to draw attention. The few times the local crows have noticed the presence of any sort of raptor, they’ve flocked together to mob the unfortunate hawk. It’s also not the right time of year; during courtship and the subsequent nesting period, these hawks are vocal, but at other times of the year, they are rarely heard. It’s also possible to mistakenly think you have heard one of these large hawks. Blue Jays have apparently learned to imitate the “kee-yar” call of this hawk, often working a flawless rendition of the whistled notes of this large raptor.

In contrast to the related Red-tailed Hawk, the Red-shouldered Hawk soars less and prefers to perch hidden in the cover of trees. This hawk’s name comes from the reddish-brown shoulder patches in the bird’s wings. Adults show a tail marked with vivid bands of black and white that is quite distinctive. The Red-shouldered Hawk belongs to the same genus of raptors as its larger relative, the Red-tailed Hawk. The genus, buteo, includes about two dozen large raptors that are often the dominant avian predators in their respective habitats.

Early naturalist and artist John James Audubon painted this pair of red-shouldered hawk.

Some of the buteo species have adapted to life on islands, including the Galapagos Hawk and the Hawaiian Hawk. Some of these hawks have quite descriptive names, including the White-throated Hawk, Gray-lined Hawk, Zone-tailed Hawk and Short-tailed 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 and Broad-winged Hawk that reminded them of the ones back in Europe.

All too often, our large hawks don’t receive the love they deserve from the public. They may even run afoul of misinformed individuals who may regard all predatory birds as “bad.” The reality is that all hawks are valuable components of a healthy, working ecosystem, with each species filling a certain niche.

Yearly survey encourages participation of citizen-scientists

Birds can bring so much excitement and entertainment into our lives, whether they are flocking to our feeders or we are seeking them out at favorite birding spots. Next month, we can do something to repay birds for all the joy their simple existence provides many of us. All that’s required is looking out your window to peek at a feeder or perhaps driving to a local park to look for birds.

Launched in 1998 by the Cornell Lab of Ornithology and National Audubon Society, the Great Backyard Bird Count (GBBC) was the first online citizen-science project to collect data on wild birds and to display results in near real-time. Bird watchers of all ages count birds to create a real-time snapshot of where birds are during the worldwide effort of the GBBC scheduled this year from Friday-Sunday, Feb. 14-17.

The Great Backyard Bird Count is a truly global undertaking.

As it has nearly every year, the 2019 Great Backyard Bird Count broke more records and attracted more participants than ever before. The GBBC is global in its scale, which provides a greater reach for dedicated citizen-scientists hoping to contribute to the well-being of the planet’s birds.

Last year’s GBBC tallied 6,699 species of birds on 204,921 checklists submitted by an estimated 224,781 participants.

U.S. participants led the way with an estimated 136,903 checklists submitted by birders in the United States. The nation of India took second place with a total of 21,524 checklists, followed by Canada (16,611), Australia (2,811) and Spain (2,391).

A total of 669 bird species were found in the United States, but that was only an eighth place finish. The country boasting the most birds was Colombia with 1,095 species. Other countries with a diversity of bird species reported included Ecuador (948), Brazil (844), India (843) and Mexico (755).

In the United States, Californians led the way in submitting checklists with a total of 10,059 surveys reported, followed by Texas (9,121), New York (8,453), Florida (7,696) and Pennsylvania (7,640). Virginia, with 6,332 checklists, just barely got edged out of the Top 5.

In my own past efforts on behalf of the GBBC, I’ve enjoyed observation of such rare East Tennessee visitors as Ross’s Goose and Canvasbacks, as well as expected birds such as Carolina Chickadees, Red-tailed Hawks and Buffleheads.

If you look no farther than your own yard and garden, please consider taking part in the 2020 GBBC. It’s free, it’s simple to do, and the results can be valuable for scientific knowledge about our fine feathered friends. To learn more about the GBBC, visit gbbc.birdcount.org.

Dreaming of winter finches flocking south

1 Reply

Photo by Bryan Stevens • Red crossbills use unique beaks to pry seeds from a conifer cone. These birds are among the so-called “northern finches” that occasionally stage massive winter migrations fueled by food shortages in their usual range. They are also nomadic residents throughout the year in northeast Tennessee and western North Carolina.

I recently got a shoutout on Facebook from Tom McNeil, a longtime birding friend and a neighbor here in the mountains of Northeast Tennessee. Tom asked if I’d been seeing any red crossbills on my side “of the ridge” and informed me he had been seeing these odd-beaked birds for the past couple of weeks.

I hadn’t noticed any crossbills and told him so, but I am definitely keeping alert for them after Tom’s notification. Every winter I hope my feeders will be visited by representatives of a group of birds known collectively as “northern finches.” This loose grouping consists of a half dozen species — purple finch, pine siskin, evening grosbeak, pine grosbeak, white-winged crossbill, red crossbill and common redpoll — that periodically stage irruptions from their traditional northern ranges to push south in large numbers during the colder months.

Photo by Bryan Stevens • A red crossbill uses its unique beak to pry seeds from a conifer cone. These birds are among the so-called “northern finches” that occasionally stage massive winter migrations fueled by food shortages in their usual range.

I’ve been feeding birds since the winter of 1993, and over the years, the first three species I listed have graced my feeders. Although I haven’t seen any this winter, pine siskins and purple finches have continued to be occasional winter visitors. Sadly, however, I haven’t been visited by showy evening grosbeaks since the late 1990s. The last time I saw an evening grosbeak in the region was back in 2000.

I’ve never laid eyes on a common redpoll, although I spent several hours 20 years ago staking out a yard in Shady Valley, Tennessee, in an unsuccessful bid to observe a redpoll that had been a reliable visitor at a feeder in that small community.

I have seen red crossbills, but my observations of these birds have always taken place during the summer months. Pine grosbeaks and white crossbills are almost unheard of in the region, and I haven’t had opportunity to visit the nesting summer ranges of these birds.

So, as the weather turns cold each year, hope springs eternal that perhaps this will be the winter that will bring some of these northern finches to my feeders, or at least to a feeder in the general area.

The factor that drives these irruptive northern finches to come south is food — or the lack thereof — in their usual ranges. When seed crops are poor in the north, these seed-eating birds may wander as far south as the Gulf States in search of supplemental food sources such as feeders stocked with sunflower seed.

Photo by Public Domain Photos/Pixabay.com • Crossbills and other finches often migrate in source of food.

The red crossbill is a specialist when it comes to foraging for its food. The bird uses its unique bill to open the cones of various conifers. The upper and lower mandibles of the bill are twisted in a way to make them cross when the beak is closed, hence the name “crossbill.”

Worldwide, there are only five species of crossbills — the red crossbill of North America, Asia and Europe; the parrot crossbill of northwest Europe and western Russia; the Scottish crossbill of Scotland; and the white-winged crossbill of Canada, the northern United States, including Alaska, as well as Asia and northeastern Europe. There’s also the endangered Hispaniolan crossbill of the island of Hispaniola in the Caribbean.

W. Herbert Wilson Jr. wrote an article about the northern finches for the Oct-Dec. 1999 edition of “North American Bird Bander.” Wilson noted that supplemental food, such as feeder fare, can influence the migratory habits of many birds, including these finches. He cited the example of black-capped chickadees, which have been shown to demonstrate an increased chance of survival during lean winter times when they have access to feeders. He also noted that the provision of food at feeders has helped birds like the tufted titmouse, house finch and Northern cardinal extend their range northward. In part, Wilson theorized that more people are feeding birds closer to the northern climes where these birds live. As a result, the long-distance irruptions are no longer necessary to find supplemental food.

Other theories have also been advanced by other experts, including changing migratory routes, diminishing overall finch numbers and climate change. Theories aside, I will continue to hope some of these birds wing their way toward my feeders this winter. If I’m lucky, this could even be the year the evening grosbeaks return! If anyone is seeing any of these “northern finches,” I’d

Winter’s dark-eyed junco provided inspiration for first column

1 Reply

Photo by Skeeze/Pixabay.com • The dark-eyed junco is a fairly common winter resident in the region. Rather widespread, different races of the dark-eyed junco are found throughout the North American continent.

I wrote my first bird column on Sunday, Nov. 5, 1995, which means this weekly column will mark its 24th anniversary this week. This column has appeared over the last 20 years in a total of six different newspapers, which I regard as a personal achievement as well as an accomplishment for our feathered friends. It’s on their behalf that I pen these weekly efforts to promote conservation and good will toward all birds. “For the Birds” has appeared in the Bristol Herald Courier since June of 2014.

Photo by Bryan Stevens •  Dark-eyed Juncos often delay their winter arrivals to the first snows of the season.

I’ve played detective, helping people identify everything from “rain crows,” or cuckoos, to Muscovy ducks and double-crested cormorants. I’ve observed unusual birds, including white pelican, brant and roseate spoonbill, in Northeast Tennessee and Southwest Virginia and spotlighted them in these columns. I still take delight in the kaleidoscopic parade of colorful warblers that pass through the region each spring and fall as well as the fast-paced duel of ruby-throated hummingbirds. I also offers to sunflower seed and other supplemental food for the resident birds like Carolina chickadees and white-breasted nuthatches.

Photo by Bryan Stevens • Known as “snowbirds,” Dark-eyed Juncos are hardy birds even in the winter season.

My first column focused on a common visitor to yards and feeders during the winter months. In fact, dark-eyed juncos should be returning to the region any day. Here, with some revisions I have made through the years, is that first column.

•••••

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

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

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.

During the summer months, a visit to higher elevations in southwest Virginia such as Whitetop Mountain or Mount Rogers is almost sure to produce sightings of dark-eyed juncos. Juncos may nest as many 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.

Photo by Ken Thomas •  Dark-eyed Juncos are also known as “snow birds” because of their tendency to flock to feeders ahead of a bout of snowy weather.

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.

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

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

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

Palm warbler’s name an unfortunate misnomer that has stuck

1 Reply

Photo by Jean Potter The palm warbler’s name is a mistaken assumption that this warbler held special affinity for palm trees. It doesn’t.

The warbler parade that begins each autumn with such brightly colored migrants as Blackburnian warbler, black-throated blue warbler and magnolia warbler usually ends with some of the less vibrant members of this family of New World birds.

On a recent bird walk at Sycamore Shoals State Historic Park in Elizabethton, Tennessee, I helped locate a flock of 13 palm warblers and a single yellow-rumped warbler. These two warblers, which look rather brownish and nondescript in the fall, pass through the region later than most other migrating warblers. In fact, the yellow-rumped warbler is one of the few warblers that routinely spends the winter months in the region.

The yellow-rumped warbler has a most suitable name thanks to the yellow patch of feathers on the bird’s rump. The resemblance of the patch to a pat of butter is uncanny enough to have encouraged birders to nickname this often abundant winter warbler the “butter butt.”

The palm warbler’s name is, at best, a misnomer. Throughout most of its life, the palm warbler doesn’t even encounter palm trees. Johann Friedrich Gmelin, a German naturalist who lived from 1748 to 1804, saddled the palm warbler with its inappropriate name. Gmelin based his naming of the bird based on the fact that a specimen had been collected on Hispaniola, an island in the Caribbean with an abundance of palm trees.

Gmelin published several textbooks in the fields of chemistry, pharmaceutical science, mineralogy, and botany. He also had a hand in publishing a catalog of scientific names for various species, including some birds that had until that point never been given a species classification. Thanks to his efforts, a warbler has forever been linked with a type of tree that is, at best, entirely incidental to the bird’s life cycle.

Early naturalist and painter John James Audubon painted these palm warblers.

Palm warblers do seek out warmer domains during the winter months, including the islands of the Caribbean. Some of them do not even migrate that far, choosing to remain along the Gulf and Atlantic coastlines of the southern United States. On occasion, individual palm warblers choose to remain in northeast Tennessee, southwest Virginia or western North Carolina during the winter months.

Every spring, however, palm warblers make a long migration flight north. This warbler is one of the northernmost breeding warblers, spending the summer months in the boreal forests of Canada. They build their nests in the thickets surrounding the many bogs along the edges of the great coniferous forests of this region of Canada.

The female palm warbler lays four to five eggs, but both parents will stay busy collecting insects once the young hatch. On an insect-rich diet, the young birds develop quickly and are able to leave the nest in 12 days. They will remain with their parents as their wings strengthen and they learn to fend for themselves.

While not able to flaunt vibrant plumage like such relatives as the Cape May warbler or the American redstart, the palm warbler is not truly as unattractive as a first glance might suggest. In fact, one subspecies, known as the “yellow palm warbler,” is quite dramatic in appearance with a profusion of yellow feathers accented with a bold russet cap and dramatic rufous striping across the yellow underparts. Even in autumn, the other palm warblers are not devoid of color. Most palm warbler show a splash of bright yellow on the throat and beneath the tail.

Photo by Bryan Stevens • A black-and-white warbler creeps over the bark of a pine in search of insect prey. The reason for this warbler’s common name is self-evident in its appearance.

In fall migration and during the winter season, palm warblers often inhabit weedy fields, grasping the dried stalks of tall weeds as they forage for berries, seeds and insects and their larvae. Look for the spot of yellow beneath the warbler’s tail, which is constantly bobbed up and down as the bird goes about its routine. The tail-bobbing behavior is a good way to distinguish this warbler from the sparrows of similar size and brown coloration that often share the fields and woodland edges.

The last of the October Saturday bird walks will be held at Sycamore Shoals State Historic Park on Oct. 26. Participants should meet in the parking lot at the park’s visitors center at 8 a.m. for a 90-minute stroll along the gravel walking trails. The walks are conducted by the Elizabethton Bird Club and are free and open to the public. Bring binoculars to increase viewing enjoyment. There’s a chance that palm warblers will be seen on the walk, but with our fine feathered friends, nothing is ever guaranteed.

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

1 Reply

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.

Photo by Bryan Stevens • Legislation like the Endangered Species Act can and does save birds like the Bald Eagle from possible extinction.

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.

Photo by Bryan Stevens • A pine siskin in a spruce at Carver’s Gap on Roan Mountain.

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

Leave a reply

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.

Photo by Jean Potter • A common nighthawk rests on a metal railing.

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.

Pigeons belong to a remarkable and diverse family of birds

Photo by Karen McSharry • This rock pigeon made a recent visit to a home in Bristol, Virginia. Not native to North America, the pigeon has been here almost since the first Europeans arrived on the continent.

Karen McSharry, a resident of Bristol, Tennessee, emailed me recently with some photos asking for help in determining an identification of the bird depicted in her photos.

“This fellow made a sharp descent and landed on my deck with a thud,” Karen wrote. “He just stood there, seemed stunned and didn’t move or make a sound.”

After an hour or so, her husband picked the bird up and set him in the wooded area behind their house.

“He doesn’t seem to be there now, over a week later,” she added.

Karen said that at first glance pigeon came to mind as she tried to identify her visiting feathered friend. “But his head is bigger and black,” she wrote. “There didn’t seem to be any iridescence.”

I wrote back and told Karen to trust her instincts. The bird she photographed was indeed a pigeon, known more formally as rock pigeon.

Once also known as rock doves, this pigeon is not native to North America, but the species has been here almost from the time the first Europeans began to sail to the shores of what eventually became the United States and Canada. The rock pigeon is native to Europe, Africa and parts of Asia, but the species has long been domesticated. Pigeons display a lot of variety in their appearance. Through artificial selection, the rock pigeon has been bred into all sorts of other patterns and colors beyond the wild bird’s standard appearance.

I don’t usually get pigeons at my home, although I did once have a domesticated bird visit my feeders for a few days. This particular bird had a band on one leg. I found out later it was a “homing” pigeon, which are pigeons trained to carry messages. After they deliver their message, they return “home,” hence the term “homing pigeon.” But they are still basically just a domesticated variety of rock pigeon.

Gordon Randall Smith, a resident of Saltville, Virginia, might be one of the region’s foremost authorities on pigeons. Eighty-one years old, he has bred pigeons for the past 76 years. He’s also raised game chickens and described his place as once being “like a zoo.”

Gordon has understandable difficulty naming a favorite domestic pigeon strain. “With hundreds of breeds available, choice becomes overwhelming,” Gordon wrote. “Throughout years of close relationships and interested involvement, preferences creep in.”

After consideration, he identified the Bohemian fairy swallow as his favorite variety of pigeon, followed by Chinese owls, crested helmets and Budapest muffed stork tumblers, as well as Lahore and Indian ribbon tailed fantails.

An uncle, Landon Smith, introduced him to the love for the propagation of a variety of domestic pigeons. “I’ve been a fancier, breeder and vivid admirer of birds throughout my amazing and very fruitful life on this planet earth,” Gordon wrote in a letter.

“I was introduced to a covey of ringneck mourning doves and pigeons at uncle Landon Smith’s passing,” Gordon noted. He described his uncle as a very dedicated person who kept various birds, animals and even exotic creatures of nature.

I looked up some of these whimsical names online. Although the basic pigeon stock is apparent in their makeup, these fanciful breeds truly show how enthusiastically the rock pigeon has embraced domestication.

In the wild, rock pigeons display an affinity for nesting and roosting on cliffs and rock ledges, hence the bird’s common name. Feral pigeons in large cities like New York have merely substituted high rises and skysrcapers for craggy cliffs.

Pigeons and doves constitute the avian family Columbidae and the order Columbiformes, which includes about 42 genera and 310 species. North America is home to several native doves, including the mourning dove, Inca dove, common ground dove, ruddy ground dove and white-winged dove. The latter was made famous in a refrain in the song “Edge of Seventeen” by Stevie Nicks.

Other doves and pigeons found around the globe include such fancifully named birds as pink-necked green pigeon, lemon dove, silvery pigeon, black cuckoo-dove, pheasant pigeon, purple-tailed imperial pigeon, topknot pigeon, common emerald dove, blue-headed wood dove, ruddy quail-dove, red-billed pigeon and Victoria crown pigeon. The diversity of form and function among wild doves and pigeons rivals anything that has been produced in their domesticated kin.

The now-extinct dodo was arguably the most famous member of the diverse family that includes pigeons and doves.

Cardinals don’t always look their best during late summer

Gina Fannin wrote about an unusual observation of a follicly challenged Northern cardinal at her home in Cincinnati, Ohio. The bird in question, a female cardinal, had lost most of the feathers on her head. Gina took a photo of the bird, which she sent with her email, in which she asked if I have ever encountered a cardinal with such a problem.

Gina said that she has seen male cardinals suffering from baldness, but never a female. “I’ve lived here 24 years, and this is the first time I’ve seen a bald female,” she wrote in her email.

I replied to Gina by informing her that I’ve heard of these strange instances for many years. Bald-headed cardinals seem to be a summer occurrence. I usually get some emails or calls this time of year about people surprised by visits from “weird bald-headed” cardinals. I first began to get calls and email from readers in the late 1990s about this unusual phenomenon that seems to usually afflict cardinals, although I have also seen blue jays suffering from this same ailment.

I have studied the opinions of various bird experts, but there doesn’t seem to be consensus about the cause. Some believe the “baldness” is caused by an infestation of mites, which are small relatives of spiders and other arachnids. Others believe that the loss of feathers around the head is a part of a normal molting process. This theory is supported by the fact that cardinals do undergo molting in late summer, usually after the conclusion of the nesting season.

The process of molting removes old feathers, which simply drop from the body as new feathers emerge to take their place. For some reason, some cardinals and jays lose all their head feathers at one time before new feathers are ready to take their place. That’s why the condition is typically observed in the summer months. Both male and female cardinals can be afflicted with “bald” heads. It’s strange that the condition primarily affects these two birds, cardinals and jays, both of which have feather crests. On the other hand, cedar waxwings are also crested birds, but I have never observed or received a report on a “bald-headed” cedar waxwing.

Whatever the cause, a “bald-headed” cardinal is an ugly bird. Without feathers, a cardinal is transformed from a showy favorite among bird enthusiasts to a rather grotesque oddity that could aptly be described as resembling a scavenging vulture. Birds like vultures, however, have heads devoid of feathers for a very important reason: As scavengers, a feathered head would become quickly fouled as the bird reaches into the carcasses of dead animals to feed.

The cardinals I have seen with “bald” heads have been visiting feeders stocked with sunflower seeds or perhaps a holder offering a suet cake. So, the absence of feathers is not a hygienic adaptation on the part of cardinals and jays similar to the hygienic necessity of bald heads among vultures. The good news is that the condition is temporary. The normal molt for a Northern cardinal takes two or three months. The feathers on the head do emerge eventually, which is probably very fortunate for the afflicted birds. Feathers serve as insulation during cold weather. A “bald-headed” cardinal would probably have difficulty surviving winter cold spells.

We’re all accustomed to seeing cardinals at our feeders, but people who feed birds would probably be surprised by how much food cardinals and other feeder visitors obtain away from our well-stocked offerings. During the summer months, cardinals eat a variety of wild seeds, fruit and insects. Some of the fruit consumed by cardinals include elderberry, dogwood, blackberry and wild grapes. Young cardinals still in the nest (and fledglings for some time after leaving the nest) are fed mostly insects, including crickets, spiders, moths and flies.

To make cardinals comfortable in every season, offer plenty of thick vegetation, such as a hedge or row of shrubs, and consider planting some of the fruit trees and shrubs that will help these beautiful birds supplement their diet.

Long-running Elizabethton Summer Bird Count finds 115 species

Leave a reply

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.
