Birding is a popular pastime for many Americans.

Mysterious nocturnal predators, owls not always what they seem

A pair of great horned owls have occupied the wooded ridge behind my rural home. Since early October, these owls have reminded me each day toward dusk the reason that many people know this large, predatory bird as the “hoot owl.” Low hoots are produced as the two individual owls call and communicate to each other. On many days, this dependable serenade begins a half hour in advance of sunset.

I love listening to the sonorous vocalizations of the great horned owl, which ranks as one of the largest owls in the region. It’s not the largest owl in North America, but it is the most widespread of the continent’s large owls. The snowy owl — popularized in J.K. Rowling fiction as Harry Potter’s loyal companion owl — is one of the largest owls in the Northern Hemisphere, bigger than such large owls as great horned owl and barred owl. The aptly named great gray owl is larger in body size than the great horned owl, but the snowy owl is heavier and more massive than either of these two contenders.

The Eurasian eagle owl takes the grand prize for size among owls of the Northern Hemisphere. This large relative of the great horned owl has been known to prey on foxes and fawns. A female Eurasian eagle owl can weight almost nine and a half pounds. The great horned owl, in comparison, usually weighs no more than about three and a half pounds. On the other hand, a large female snowy owl may weigh as much as 6.6 pounds. As is often the case with raptors, females are larger than males.

Owls, by and large, have been transformed in our time into beloved birds, the stars of viral videos distributed by social media. We no longer think of owls as portents of doom and gloom. While owls still reign supreme once the sun sets and darkness dominates, we no longer fear them. Instead, we’re fascinated by them. As a result, long-standing misunderstandings have fallen by the wayside as we learn more about these incredible birds.

The great horned owl lives and hunts in the woodlands of northeast Tennessee, southwest Virginia and western North Carolina. They thrive in rural areas, but these adaptable owls have also learned to make their way in the suburbs and even city parks. Not by any stretch of the imagination, however, is this owl confined to the southern Appalachians. These owls also make their home in the wetlands along the southern Atlantic coast, as well as arid deserts of the American southwest.

While human culture has turned owls into beloved creatures, keep in mind these birds are fierce and ferocious predators. For young American crows in their nests, this owl is the stuff of their avian nightmares. It’s no wonder that crows, which no doubt witness their peers taken by the great horned owl as prey when young and helpless, grow up with an abiding hatred of this large nocturnal raptor. Flocks of adult crows form quickly when an owl is discovered at a roost during the daylight hours. With safety in numbers, the crows mercilessly hound and harry such unlucky owls.

Quite often, it does take a crow’s sharp eye to detect a motionless owl at its daytime roost. Great horned owls have a plumage of mottled grays and browns, as well as some white feathers on the chin and throat. This plumage helps them blend into their surroundings. Even when on the move, the great horned owl rarely attracts attention. They can fly in almost perfect silence on their wide wings.

Crows are not the only wildlife with good reason to fear the great horned owl. This predatory bird feeds on the nestlings of other raptors. The great horned owl also preys on ducks and other waterfowl, rabbits, other small rodents, as well as some reptiles, amphibians and even bats.

Here are a few other interesting facts about the great horned owl:

• This owl is one of the few predators that preys regularly on skunks. Lacking a well-defined sense of smell, owls aren’t bothered in the least by the skunk’s powerful arsenal of stink.

• A wild great horned owl’s longevity peaks at around 13 years of age. Captive owls have been reported reach ages of more than 30 years old.

The owl symbol from the 1990s drama, Twin Peaks.

• Various Native American tribes have held owls in high respect. Dwight G. Smith, author of Great Horned Owl, a book in the Wild Bird Guides series, noted that members of the Zuni tribe of the southwestern United States often hold owl feathers in their mouths to impart the owl’s ability to hunt silently onto their own hunting abilities.

• The David Lynch drama Twin Peaks, which ran originally on ABC from April of 1990 to June of 1991, spent considerable time dwelling on the mystery that “the owls are not what they seem.” Footage of great horned owls provided a sinister, mysterious mood that fascinated viewers. The series is being resurrected in 2017 on Showtime, so fans may finally learn the truth about the owls and their importance to the fictional town of Twin Peaks.

There’s nothing to send shivers traveling along your spine like listening to the haunting hoots of a great horned owl hidden from human eyes by the cloak of darkness. It’s no wonder that owls have also become popular motifs for the celebration of the Halloween holiday. Just remember there’s more to these creatures of the night than perhaps meets the eye. Owls may be our neighbors, but we’ll never truly belong to their world, which must be why they continue to intrigue us.

Winter birds bring their own winning ways to region as weather turns colder

Leave a reply

Erwin resident Don Dutton called me recently to ask about hummingbirds. He hasn’t seen many this past summer season, but as I told him, their numbers fluctuate from year to year. Most of the ruby-throated hummingbirds have now departed the region. I did encourage him to keep his sugar water feeders hanging as fall gets closer to the colder weather of winter. You never know when a rufous hummingbird or other western species might stray into Northeast Tennessee.

Photo by Bryan Stevens A young male Rufous Hummingbird at my feeder in Hampton, Tennessee, on Oct. 13.

In fact, I’ve been visited twice since the first of October by a young male rufous hummingbird. It’s easy to tell the rufous from the ruby-throated hummingbird. The rufous shows a great deal of brown/rufous coloration in its plumage. The bird at my feeders visited on Oct. 7 and again on Oct. 13. I’m very hopeful the bird will linger for a spell. I am asking anyone who sees a hummingbird in the coming weeks to let me know by sending an email to ahoodedwarbler@aol.com.

Photo by U.S. Fish and Wildlife Service/George Gentry An evening grosbeak, the largest of the winter finches that stage occasional irruptions southward in search of food, visits a feeder. Could this be the year these colorful birds return to the Southern Appalachians?

With October already halfway completed, it’s time to stop lamenting the end of summer and brace for another winter. The cold season brings an entirely new range of birds to the region for our viewing enjoyment. If nothing else, winter birds provide a tremendous morale boost to help us overcome the occasional gloom of the winter season. There’s nothing quite as entertaining as watching a large, boisterous flock of birds like evening grosbeaks or pine siskins at your feeders.

So, some of our favorite summer birds have flown south. We’ll miss them, but we will see them again next spring. In the meantime, winter offers its own bird diversity.

Here are some of the types of birds to enjoy as the weather outdoors becomes colder.
Ducks and other waterfowl. The U.S. Fish and Wildlife Service conducts yearly surveys of the breeding success of native ducks. In cooperation with the Canadian Wildlife Service, this year’s survey has some mixed news for those birders eager to observe ducks later this fall and in the winter at area lakes, rivers and ponds. Im love to check the pond at Erwin Fishery Park and the ponds along the linear trail for visiting waterfowl once the weather turns colder. The figures from the report came from surveys conducted in May and early June.
Overall duck numbers in the survey area are statistically similar to last year and remain steady. Total populations were estimated at 48.4 million breeding ducks in the traditional survey area, which is 38 percent above the 1955-2015 long-term average.

Last year’s estimate was 49.5 million birds. The projected mallard fall flight index is 13.5 million birds, similar to the 2015 estimate of 13.8 million.
American wigeon, green-winged teal and redhead are two ducks that are expected to show an increase in numbers.
Unfortunately, some other species showed declines, including Northern shoveler and canvasback.

Photo by Bryan Stevens Northern finches, such as this Pine Siskin, may come south in large numbers.

Other waterfowl that could join the annual migration of ducks include everything from loons and grebes to geese and cormorants.
Northern finches. Reports from the Northeastern United States indicate that the cone crop — a vital food source for a variety of songbirds —has been extremely poor. Reports from Canada indicate more of the same, which could result in a variety of the so-called Northern finches — pine siskin, common redpoll, purple finch, red crossbill, white-winged crossbill and evening grosbeak — heading south in massive numbers as they seek out alternative food sources.
I’d be thrilled to see flocks of common redpolls or evening grosbeaks at my feeders, although the more likely visitors are probably pine siskins and purple finches. I haven’t hosted evening grosbeaks at my feeders since the late 1990s. In fact, I haven’t seen an evening grosbeak since 2000. Perhaps this will be the year these large, colorful and energetic finches overwhelm our feeders once again.
The coming winter could be a very interesting one for birders. Keep your eyes open and your binoculars handy.
Sparrows. Although we have a few sparrows in our yards and gardens during the spring and summer, this group of birds often referred to as LBBs, or Little Brown Birds, really comes into its own during the winter season.
Some of the sparrows that may come to feeders during the colder months of the year include white-throated sparrow, white-crowned sparrow, swamp sparrow, field sparrow, and fox sparrow. Technically, even the Eastern towhee and dark-eyed junco are members of the sparrow family, although they lack names containing the word “sparrow.”
Many of the sparrows prefer yards offering dense cover, such as hedges, brush piles or evergreen trees.

Photo by Bryan Stevens Red-breasted Nuthatches are already showing up at feeders throughout the Southern Appalachians.

If you enjoy a challenge, set yourself the task of learning the subtle differences between some of our native sparrows.
Nuthatches and woodpeckers. Although the woodpeckers are present throughout the year, it’s often easier to observe these “tree-huggers” once the leaves are off the trees.
A couple of species, including the red-breasted nuthatch, red-headed woodpecker and yellow-bellied sapsucker, are migratory birds with numbers that fluctuate from year to year.
I’m learning about reports that elevated numbers of red-breasted nuthatches are already winging their way south. These tiny birds with their “yank, yank” calls are immensely entertaining at feeders. They love sunflower seeds and peanuts, so make sure you have plenty of their favorites ready and waiting for them.

Arduous migration journeys by some birds represent wondrous natural achievements

Photo by Bryan Stevens This rose-breasted grosbeak struck a window Monday, Oct. 3, during fall migration. Although this bird rested and later recovered, many birds are felled by similar perils and obstacles as they migrate south each fall.

A stunned rose-breasted grosbeak recuperating on the front porch on Oct. 3 provided a reminder that migrating birds face a variety of perils and obstacles as they wing their way back south. Now that we’re into October, many of the birds of summer — orioles, tanagers, warblers and hummingbirds — are becoming scarce in our yards and gardens. These neotropical migrants are temporary visitors, remaining in North America only long enough to nest and raise young before they take to the wing to return to more tropical regions for the winter months that will grip their summer home in snow and ice for several months.

Some of these birds migrate out of the tropics to avoid competition. Others find North America a land of abundant, albeit temporary, resources. This land of plenty offers a wealth of insects, seeds, fruit and other nourishing, nutritious food to help parent birds keep their strength while they work to ensure their young thrive. The phenomenon of migration isn’t exclusive to the neotropical migrants of the New World. Birds in other parts of the world migrate, too.

Photo by U.S. Fish & Wildlife Service The tiny ruby-throated hummingbird crosses the Gulf of Mexico twice yearly to migrate from Central America to North America in the spring and back again in the fall.

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.

The ruby-throated hummingbird, a favorite of many bird enthusiasts living in the eastern United States, makes an impressive migration each year. 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.

The broad-winged hawk, a raptor found in the region during the summer, makes a fall migration back to South America every fall that astonishes human onlookers who gather along mountain peaks to witness the spectacle. The hawks form large flocks, also called kettles, that can number thousands of birds.

Photo by U.S. Fish & Wildlife Service/Steve Maslowski The bar-tailed godwit stages migrations that can take nine days of non-stop flight spanning nearly 6,000 miles.

Shorebirds, which in North America can consist of birds ranging from plovers and godwits to dowitchers and avocets, are champion migrants. The bar-tailed godwit makes an even more impressive non-stop migratory flight. This shorebird nests in parts of Scandinavia, northern Asia and Alaska. Some of these godwits make a nine-day non-stop migratory flight that takes them from New Zealand to the Yellow Sea of China, a distance of almost 6,000 miles. Needless to say, since the godwits make no stops along the way, they must also go without food for the duration of their journey.

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.

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.

Photo by U.S. Fish & Wildlife Service/Kirk Rogers The Arctic tern’s migration, which takes it from the Arctic to the Antarctic, keeps this small seabird in the sky for about 50,000 miles each year.

Birds are not even the only animals to migrate. Many creatures, from whales and wildebeest to dragonflies and butterflies, impress humans with their endurance as they stage regular migrations.

Even as some of our summer favorites depart, we should prepare to welcome back some winter favorites, including dark-eyed juncos, yellow-rumped warblers, white-throated sparrows and yellow-bellied sapsuckers. Fall is indeed a time of departure for many birds, but it’s also a time to make new friends with the other birds that should soon start arriving in our yards and gardens.

As for the rose-breasted grosbeak on the porch, that story had a happy ending. After taking some time to recover after apparently striking a window, the bird hopped around the porch for a moment and then took wing and flew to nearby hawthorn trees. The bird’s flight — strong and straight — delighted me. The grosbeak could have been badly injured or even killed. I wished it the best for the remainder of its journey.

I’m dedicating this week’s column to the memory of J. Wallace Coffey, a great birder and wonderful individual who died Tuesday, Sept. 27. I met Wallace, a native of Bristol, Tennessee, back in the late 1990s. He introduced me to some wonderful birding destinations in the region, including such Virginia locations as Burke’s Garden, Steele Creek Park in Bristol, the wetlands of Saltville and Musick’s Campground on Holston Lake. Wallace was a tireless promoter of birds, birding and birders, and he loved to encourage young people to explore nature. He was also a great leader for the Bristol Bird Club, as well as the Elizabethton Bird Club. He will be greatly missed.

Summer’s bright American goldfinches will soon transform into their dull winter plumage

Leave a reply

Photo by Bryan Stevens An American goldfinch feeds on thistle seeds from a feeder designed to contain these tiny seeds.

I received a phone call recently from Allan Vance, who had a question about American goldfinches. Allan told me he moved back to Bristol about nine years ago after living for about 30 years in Savannah, Georgia. He now resides in the community of Middlebrook, where he feeds the various birds that flock to his yard.

Allan explained that the goldfinches had become conspicuous in their absence from his yard starting a few weeks ago. “I haven’t seen a single one in weeks,” he said.

A thistle sock with seeds favored by American goldfinches.

Allan purchases thistle socks for the flock of goldfinches at his home. These “socks” are actually long, mesh bags holding the tiny seeds of the nyjer plant. Although these seeds are also known as thistle seeds, they are not related to the thistle plants that are sometimes classified as noxious weeds. Finches are able to cling to the sides of the mesh socks as they carefully remove the seeds. The tiny seeds are quite securely held within the mesh socks. Special feeders with small ports for dispensing of these tiny seeds are also available.

After he purchased his most recent thistle sock, Allan expected the birds to visit it as is their usual custom. After several weeks, only one bird — not a goldfinch — had visited the sock. He wondered if there might be some explanation behind the goldfinches suddenly turning their backs on these favorite seeds.

I explained that there were two possible reasons, which are somewhat connected to each other, for the goldfinches suddenly shunning the sock. It’s early fall and there’s an abundance of natural food sources available to fold finches. Many roadside, fields and gardens are filled with plants that are already producing a banquet of fresh seeds for finches and other seed-loving birds. It’s possible that, faced with a smorgasbord of other foods, the goldfinches are no longer quite as reliant on the seeds in Allan’s thistle socks.

The American goldfinch is also one of the last songbirds to nest each season. Some goldfinches don’t even start to think about nesting until late July and early August. Their nesting season is timed to coincide with a time of natural abundance. Goldfinches feed their young mostly on insects, as opposed to most songbirds that work so hard to gather insects to feed their young a protein-rich diet.

It’s a satisfying irony that, although brown-headed cowbird females sometimes slip their eggs into a goldfinch nest, any young hatched in those nests rarely survive. While goldfinch hatchlings are adapted to thrive on a diet of seeds, the fostered young cowbirds fail to thrive on a diet so lacking in insects.

In addition to feeding birds, his yard serves as a place for them to nest. He noted that wrens have successfully nested at his home over the years. He said a funny memory from years ago involved a white-tailed deer at a feeder. “I saw this doe raiding my feeder,” he said, adding that the deer used its tongue to lick seeds from the feeder.

Photo by Bryan Stevens A fall American goldfinch looks quite different than it does at the height of summer.

The male American goldfinch during the breeding season is unmistakable in his bright yellow and black plumage. Female goldfinches are more subdued in coloration. Males also sing a bubbly, cheerful song when seeking to win the attention of a potential mate. Outside of the nesting season, goldfinches are quite sociable and form large flocks. Dozens of these small songbirds can descend on feeders at almost any time of the year, but they are primarily attracted to our feeders during the lean times of the winter months.

For these and other reasons, goldfinches are favorites of many bird lovers. There are actually three species of goldfinches in North America. The two related species are Lawrence’s goldfinch of California and the lesser goldfinch, which ranges through the southwestern United States as well as Central and South America.

Photo by Bryan Stevens A male American Goldfinch perches on a barbed wire fence.

The American goldfinch is also known by other common names, including wild canary, yellowbird and willow goldfinch. I’ve also heard the goldfinch referred to as “lettuce bird.” This nickname, which was one my maternal grandmother applied to the bird, relates to the bird’s fondness for seeds. Apparently the goldfinches would flock to lettuce plants in the garden once they had gone to seed.

Come winter, this vibrant bird undergoes a transformation into a dull, drab bird with grayish feather. In fact, this annual molt usually begins in September. During the fall and winter, the American goldfinch looks almost like an entirely different bird.

It’s understandable why people love to entertain flocks of these finches in their yards and gardens. Three states — Washington, Iowa and New Jersey — have made the American goldfinch their official state bird.

Hooded warbler favorite member from an exceptional family of birds

2 Replies

Photo by Bryan Stevens Hooded Warblers, like this male, prefer to remain in the shadows of shrubs and thickets.

A plushie Hooded Warbler.

I watched a male hooded warbler flitting among the branches of a forsythia shrub during a soft rainfall on Sept. 18. As I watched the small bird dash after unseen insects among the thicket formed by the forsythia branches, I marveled at the bird’s exquisite appearance. The gold and green feathers seemed to glow brightly in the dim light as a drizzle of rain wet both bird and leaves. The black hood and bib surrounding the male’s yellow face stood out by virtue of its stark contrast from the brighter feathers.

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 flick as the move about in thick vegetation and shrubbery.

I know that every migrant passing through my yard is making its way south and it may 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 Belize, Costa Rica and other Central American nations. 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.

Photo by Jean Potter A male Hooded Warbler perches in a rhododendron thicket.

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.

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. As I’ve indicated in recent columns, however, some members of the family show more subdued plumages of tan, beige and brown. 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. None of the eastern warblers show any true red in their plumage, but red and pink warblers can be found south of the border. The pink-headed warbler, red warbler and red-faced warbler all make their home in Mexico and and Central America.

Photo by Bryan Stevens A male Hooded Warbler perches in a thicket during a fall migration stopover.

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 the lives of the lucky humans fortunate enough to observe them during the summer nesting season or the seasonal migration journeys.

Photo by Bryan Stevens The male Hooded Warbler isn’t likely to be mistaken for any other warbler.

The hooded warbler has long been my favorite member of this family of interesting, energetic and engaging songbirds. Hooded warblers reside in the woodlands around my home, nesting and rearing young each year. I’ve never found a nest, but many years ago I watched a pair of hooded warblers fend off a song sparrow that ventured too close to one of their fledglings. Of course, the sparrow posed no realistic threat to the young warbler, but that didn’t make the conflict with the hooded warblers any less intense. The poor sparrow looked completely befuddled and uncertain about its offense. After the warblers drove the sparrow from the vicinity, I watched both parents deliver some food to the young bird.

Like most warblers, the hooded warbler feeds almost exclusively on small insects and arachnids. Some warblers will also feed on fruit, seeds and even nectar. The hooded warbler favors habitats featuring woodlands with an understory of smaller trees and shrubs, such as stands of willows or rhododendron thickets. Of course, a tangle of forsythia is enough to attract a visit from a migrating hooded warbler.

The warblers have become such popular songbirds that they warrant field guides devoted exclusively to their ranks. My long-time favorite guide is Warblers of the Americas by Jon Curson, David Quinn and David Beadle published in 1994. More recently, other guides have been published, including A Field Guide to Warblers of North America, a book in the Peterson Field Guide series, and the Stokes Field Guide to Warblers. If you want a book to enlighten you about the magic of this family of birds, consider Chasing Warblers, a book by Bob and Vera Thornton about an adventure to find and photograph all 52 species of warblers that nest in the United States.

John James Audubon painted this image of Hooded Warblers about two centuries ago.

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 few months they are here, the warblers belong to us. They seem like “our” birds. They’re only on loan, though. Our winter birds bring their own favorites back to our yards, but I’ll be impatiently awaiting that flash of gold in the shadows of a rhododendron thicket next April.

Ovenbird often a difficult bird to get to know

Leave a reply

Last week, I discussed the worm-eating warbler, which is one of the more drab warblers in terms of appearance. I think that must have started a trend, because so far this migration season has been dominated by some of the less colorful — but still very interesting — warblers. The opening days of September brought with them the annual fall parade of migrating warblers. As usual, this yearly opportunity to view visiting warblers began as a trickle of species but has picked up in intensity as each day passed.

Photo by Jean Potter Ovenbird sings from an elevated perch in the woodland canopy.

By Sunday, Sept. 11, I had already observed close to a dozen species of warblers, including hooded warbler, black-throated green warbler, Northern waterthrush, ovenbird, magnolia warbler, chestnut-sided warbler, black-and-white warbler, Tennessee warbler, and American redstart.

One of the first warblers to arrive at my home this spring was the enigmatic ovenbird. With its loud, ringing song — “Teacher! Teacher! Teacher!” — it’s impossible not to notice the arrival of this warbler. Why describe this warbler as enigmatic? For starters, ovenbirds do not easily permit even stealthy birders to glimpse them. I have gotten good looks at ovenbirds throughout the years, but they are still difficult to observe. They are one of the warblers more easily heard than seen. When they are observed, it’s usually no more than a fleeting look before the bird dives back into heavy cover. That’s not always the case, however.

Photo by U.S. Fish & Wildlife Service/Steve Maslowski The ovenbird is not named for its plumage or its habitat preference. Instead, its name refers to the shape of its nest. Ovenbirds and other warblers are currently migrating through the region.

I’ve actually seen three different ovenbirds this fall, with increasingly good looks at this warbler each time I have encountered it. The ovenbird is not one of the brightly colored warblers, such as black-throated blue warbler or yellow warbler. The ovenbird is a small brown bird with a white breast with dark streaking — an appearance that bears a superficial resemblance to the larger thrushes that share the same woodland habitat. The only hint of color is an orange crown bordered by dark stripes atop the bird’s head. Even this orange crown patch is not easily seen. When agitated, an ovenbird may raise its head feathers, which makes this orange mark easier to detect. The ovenbirds I’ve observed recently have all shown off that orange crown patch to great effect. The ovenbird also has a distinct white ring around its eyes, as well as pink legs and a pinkish bill.

Early naturalist John James Audubon painted a pair of Ovenbirds, which he knew as “Golden-crowned Thrushes.”

The ovenbird, unlike many warblers, is not named for its appearance. Instead, the bird’s name derives from the shape of the nest it builds. The nest is a domed structure placed on the ground, woven from vegetation and containing a side entrance. Early European settlers in North America thought the nest looked like a Dutch oven, hence the name “ovenbird” for the small warbler with the intricate nest.

Rather than hopping along the length of a branch or limb, an ovenbird walks in a deliberate fashion. This bird feeds on insects, spiders and other small prey items foraged from the woodland floor. On rare occasions, a lingering ovenbird shows up at feeders during the winter months.

Ovenbirds spend the summer nesting season in mature deciduous and mixed forests across Canada and the eastern United States. They do not make as lengthy a migration as that undertaken by some of their relatives. Ovenbirds migrate each fall to the southeastern United States, the West Indies, and from Mexico to northern South America for the winter season.

The two warblers most closely related to the ovenbird are the Louisiana waterthrush and Northern waterthrush. These atypical warblers share a preference for leading lives spent mostly near the ground adjacent to streams. The Louisiana waterthrush seeks out the rushing water of our mountain streams during early spring while the Northern waterthrush prefers quiet pools of water farther north during its nesting season. The ovenbird, however, is not as closely associated with water.

Amateur ornithologist and artist Genevieve Jones painted this depiction of the Ovenbird’s namesake nest.

While I have used the adjective “drab” to describe some of these brown warblers, it is not truly accurate. Although these warblers lack bright colors like orange, yellow and blue, they have an incredible, subtle beauty all their own. In the coming weeks, I will discuss some of the brighter warblers in this fascinating family of migratory songbirds.

Warblers are not the only birds migrating through the region. Other notable migrants I’ve observed recently have included common nighthawks, red-eyed vireos and green herons.

Worm-eating warbler less conspicuous member of family of bright, active migratory songbirds

It’s September, which for me signals the autumn migration season of warblers and other neotropical birds. The warblers are a family of small songbirds that also happens to be the main reason I enjoy bird watching. Although warblers can be a challenge to observe and a puzzler to identify, they’re bundles of multi-colored feathers brimming with high-octane energy as they forage in treetops, along woodland edges, in weedy fields and around ponds and streams.

Like all migrating birds, warblers face numerous obstacles and hazards as they fly back south every fall after spending most of the spring and the entire summer spread across the United States and Canada for the season of nesting and raising young. Storms, such as the recent Hurricane Hermine, can be a hazard. Predatory raptors, like peregrine falcons and merlins, follow the migration routes and pick off various migrants. Even something as mundane as a window pane can bring a tragic halt to migration each year for thousands of our smaller songbirds.

I recently received an email from Chris Soto, a fellow member of the Lee and Lois Herndon Chapter of the Tennessee Ornithological Society. Her sister, Dianna Lynne Tucker, resides in Elizabethton, Tennessee, near Holston Mountain. Her home has a yard that is a magnet for a variety of songbirds. One of the birds passing through her yard had an unfortunate impact with a window. Chris and Dianna already suspected the identity of the bird, but they emailed me asking for help to confirm it. I concurred that the bird was a worm-eating warbler.

“After a brief rest, the bird recovered,” Chris noted in the email. I always like a story with a happy ending.

The scientific name for this warbler is interesting. The worm-eating warbler, or Helmitheros vermivorum, is in a genus of one. It’s the only species contained within the genus. Vermi means “of or relating to worms” while vorum is related to eating. Hence, vermivorum is quite literally an “eater of worms.” The worms in this warbler’s diet, however, are not earthworms. Instead this bird feeds on caterpillars, the larval form of moths and caterpillars. The worm-eating warbler has one unusual foraging method to look for caterpillars. This warbler will often cling to a cluster of dead leaves while probing into the tangle to seek out any concealed caterpillars, as well as small insects and spiders. All in all, the worm-eating warbler doesn’t feed any more exclusively on caterpillars than other warblers.

This warbler’s non-musical song is a dry trill that compares with the songs of chipping sparrows and dark-eyed juncos. Since these other birds can be found in similar habitats, it can be a bit of a challenge for beginners to identify this warbler by sound alone. The worm-eating warbler isn’t one of the more colorful members of the family. It has a subtle beauty, however, with a plumage of brown and buff feathers. The most distinctive part of its appearance are the black stripes that run along the crown and a dark stripe through the eye. This warbler has a pinkish bill. Both males and females look alike.

According to the website All About Birds, the oldest worm-eating warbler ever documented was a male that was at least eight years, one month old when he was recaptured and rereleased during banding operations in Connecticut. I’ve seen fewer of this particular warbler over the past ten years, but the overall population figures for this species have actually trended slightly upward. The worm-eating warbler’s population is concentrated in the southeastern United States. It favors deciduous woodland habitat with shaded banks, steep gullies and ravines. The habitat around my home must have changed enough that they are no longer a frequent visitor. The worm-eating warblers will migrate to Mexico and Central America this fall, electing to spend the winter months in warmer terrain.

Warblers and their active lifestyles can be a challenge for human observers. Nevertheless, it’s worth the effort to seek out these colorful, energetic and interesting songbirds. Many people like to look for returning spring warblers, but I’ve always found the fall season the best time to look for these birds. September is the month when the majority of these warblers will migrate through our region. Warblers ignore offerings of seeds at our feeders, but a bird bath, ornamental fountain, pond or stream is like a magnet drawing these migrants to stop, enjoy a cool drink and a vigorous splash in the inviting water.

Keep a pair of binoculars at hand and your eyes open. If you’d like to share your observations of migrants passing through your yard this fall, I’d love to hear from you.

Grosbeaks in region include blue, rose-breasted representatives of family

Leave a reply

Daryl Herron, a real-life friend as well as a Facebook one, posted a photo of a bird on my page recently, seeking help with identifying the bird. His sister, Monica Cody, took the photo at her Kingsport home. The stunning bird depicted in the photo, as I happily reported back to Daryl, was a blue grosbeak. The grosbeak is an impressive bird, with males showing off an overall blue plumage save for some brown and black feathers in the wings.

Rose-breasted Grosbeaks will likely be among the colorful birds present for this year’s rally.

Blue grosbeaks are mostly southern birds with Tennessee, Kentucky and Virginia representing the northern tier of this bird’s range in the southeastern part of the country. Look for these chunky, blue birds in brushy fields or along hedgerows in fairly open country. They favor the same habitats as such birds as yellow-breasted chat, brown thrasher and loggerhead shrike.

Photo by Monica Cody This male blue grosbeak showed up near Monica Cody’s home in Kingsport, Tennessee. The blue grosbeak is an uncommon visitor in the region.

It’s a shame this bird isn’t more common in the region. Blue grosbeaks will visit feeders, but in more than 20 years of maintaining well-stocked feeders, I’ve managed to attract only one of these birds. If more common, it would surely be a favorite bird among the people offering free seed for their feathered friends.

The blue grosbeak is related to the better-known rose-breasted grosbeak. Male rose-breasted grosbeaks are absolutely stunning, especially for people getting their first-ever glimpse of this bird. It’s the adult male with his vibrant black and white feathers and the large rosy-red splash of color across the breast that gives this bird its common name. Females are brown, streaked birds that are larger than but easily confused with some of our sparrows.

Among grosbeaks, both sexes have a massive bill, which they use to hull sunflower seeds at feeders or glean insects from leaves and branches. It’s the heavy, blunt bill for which the term “grosbeak” is derived. “Gros” is a German term for large or big, so grosbeak simply means a large-beaked bird. People who band birds to further the study of them will tell you that rose-breasted grosbeaks have a wicked bite and are capable of delivering quite a nip. Bird banders in the region frequently encounter rose-breasted grosbeaks in their mist nets — and some bear the scars to prove it.

Photo by Tammie Kroll The male rose-breasted grosbeak is probably one of the least difficult songbirds to identify with his unmistakable plumage pattern.

The spring arrival of rose-breasted grosbeaks is usually a fleeting visit. Finding suitable arrangements, which can consist of well-stocked feeders and perhaps a convenient water source, the migrating birds may linger for several days. These birds nest at higher elevations, however, and are usually impatient to continue the journey to where they will spend the summer months tending to their young.

This spring, Tammie Kroll was one of the lucky people to receive visits from rose-breasted grosbeaks. Tammie emailed me to share a beautiful photo she took of the male grosbeak that visited her home in Washington County, Virginia, near Exit 13 off Interstate 81.

There’s good news for those who didn’t receive springtime visits from these pretty birds. The rose-breasted grosbeak is also a common fall migrant and can again be attracted to yards offering sources of food and water. While males usually don’t look quite as dramatic by August and September, they’re still sure to cause a stir when visiting a feeder.

Photo by Bryan Stevens A rose-breasted grosbeak sings from a tree on Roan Mountain, Tennessee.

Plenty of rose-breasted grosbeaks pass through northeast Tennessee, southwestern Virginia and western North Carolina, and a few even decide to make their summer homes in the mountains in these regions. However, these birds spread out widely across the eastern half of the North American continent, ranging from northeastern British Columbia to Quebec and Nova Scotia in Canada. They also range south from New Jersey to Georgia. The rose-breasted grosbeak also reaches Colorado, Oklahoma and Kansas.

John James Audubon painted this family of blue grosbeaks.

For the most part, however, the rose-breasted grosbeak is replaced in the western United States by the closely related black-headed grosbeak. I saw several of these birds during a trip to Salt Lake City, Utah, back in 2006. Other grosbeaks in the United States include the evening grosbeak and pine grosbeak. In the American tropics other grosbeaks are found, including the descriptively named yellow-green grosbeak, crimson-collared grosbeak, ultramarine grosbeak and yellow-shouldered grosbeak.

Moths, songbirds share top billing for programs at this year’s Roan Mountain Fall Naturalists Rally

Leave a reply

For 54 years the annual Roan Mountain Fall Naturalists Rally has brought nature enthusiasts from near and far to the slopes of Roan on the weekend after Labor Day. The tradition continues this year Friday-Sunday, Sept. 9-11, with two area naturalists presenting evening program on moths and songbird behavior.

For this year’s rally, the program spotlight will shine on local moths and songbirds. As always, a variety of walks, hikes, strolls and workshops will also be offered on Saturday and Sunday. Top naturalists volunteer their time and energy to make the event both enjoyable and educational for people of all ages.

This fall rally continues to celebrate the natural world by providing two top speakers for this year’s event. Larry McDaniel, a naturalist at Steele Creek Park in Bristol, Tennessee and a long-time member of the Friends of Roan Mountain, will deliver the program on “Moths of Roan Mountain and Northeast Tennessee.” Dr. Steven Hopp, naturalist and teacher at Emory and Henry College in Virginia, will present a program titled “Beyond Birding: A Look at the Life History of Local Songbirds.”

Steven Hopp teaches at Emory and Henry College in Virginia.

Because of the continued support of the Friends of Roan Mountain, the seasonal rallies have the resources they need to prosper and grow and the FORM provides support for research and restoration projects on the Roan, as well as support for Roan Mountain State Park. Consider joining the Friends of Roan Mountain, if you are not a member. Members get free admission to all Naturalists Rally events and the organization’s newsletter, “Friends of Roan Mountain.” Gary Barrigar, director for the fall rally, said many thanks are due to Roan Mountain State Park’s staff for long-time support of the rallies, as well as the speakers and the trip leaders who donate their time and expertise.

Clymene Moth

Evening and lunch programs will take place in Roan Mountain State Park’s Conference Center and field trips will leave from the field located on the left before the cabins in the park. A variety of morning and afternoon field trips are planned on topics ranging from butterflies and salamanders to birds and wildflowers.

McDaniel, the Friday evening speaker, grew up in College Park, Maryland, where he spent a great deal of time exploring in the woods. It was there that he developed a lifelong love for nature. He started birding while in high school and has been going at it ever since. He spent 15 years living and birding in Florida. It was during those years that he started traveling all over North America to see birds. He moved to Bristol, Tennessee, in 1993 and started attending the Roan Mountain Naturalists Rallies within weeks of having moved to the area. Legendary Bristol birder Wallace Coffey introduced him to the area and the birding community where he has met and spent time in the field with many outstanding birders and naturalists. While working as a letter carrier in Bristol he began volunteering to lead bird walks in the area.

Large Maple Spanworm Moth

He eventually became involved with the Bristol and Elizabethton bird clubs and served several years as the president of the Bristol club. Like many birders, during the 1990s he branched out and began studying butterflies, dragonflies and damselflies, reptiles and amphibians, wildflowers and a little of just about everything. Soon he began leading bird hikes for the Roan rallies and before long became a board member of the Friends of Roan Mountain. In 2006, having retired from the Postal Service, he started working as a naturalist at Steele Creek Park, where he has been for ten years. He increased his interest of insects during this time and in 2008 he started studying and photographing moths. Local naturalist Don Holt helped to get him started in that endeavor.

Hummingbird Moth

McDaniel, lives with his wife, Janet Brown, on a hobby farm near Johnson City, where they tend a menagerie of mini-farm animals. Larry and Janet met at a Roan Rally and in 2003 got married in Roan Mountain State Park.

His presentation will discuss many aspects of the natural history of moths and the growing trend of studying them. It will include many of his photographs of moths from Roan Mountain State Park and the Tri-Cities area. He has photographed about a thousand species of moths, but he promises he won’t include them all in the presentation.

Dr. Steven Hopp will be the feature Saturday evening speaker. Hopp is broadly trained in the life sciences, and received his Ph.D. in Animal Behavior from Indiana University. He moved to southwest Virginia in 1984 to teach at Emory and Henry College, and has been tied to this region ever since. He taught ornithology courses at the University of Arizona from 1994 to 2004, at which time he moved back to Virginia full time. He teaches courses in wildlife management and sustainable agriculture in the Environmental Studies program at Emory and Henry.

Blue-headed Vireo

Dr. Hopp has studied different species of vireos for over 25 years. His main interest is in their vocal behavior, but he has broadly studied their natural history including life history strategies, breeding ecology and behavior on their wintering grounds. More recently, he has become interested in Sustainable Agriculture, and is co-author of the national best-selling book, Animal Vegetable Miracle, with his wife, Barbara Kingsolver. The book is about local food systems and sustainable agriculture. He is founder and director of The Meadowview Farmers’ Guild, a community development project devoted to promoting local products, with an emphasis on agriculture. He serves on the board of Appalachian Sustainable Development. Hopp and his wife live in Meadowview, Virginia, on a mostly wooded farm with Icelandic Sheep and Dexter Cattle.

The evening programs are scheduled for 7:30 p.m. Prior to the programs, evening meals catered by City Market of Elizabethton, Tennessee, will also be served on Friday and Saturday, Sept. 9-10. Cost is $9.50 for adults and $5 for children 12 and under. A bag lunch is also available on Saturday for field trip participants for $6. Advance reservations are required for the meals and bag lunch.

Tremulous call of Eastern screech-owl baffles couple

Leave a reply

Photo by Bryan Stevens
An Eastern Screech-Owl at rest in a roosting hole in a large sycamore tree.

I received a recent email from Lewis Chapman seeking help in solving the identity of a nocturnal caller. Chapman and his wife moved to Laurel Bloomery in Johnson County, Tennessee, in late June.

“Shortly after we arrived we started hearing a strange night bird call that could best be described as an eerie winnowing,” he wrote in his email. After the couple conducted some Internet research into the mysterious after-hours vocalist, his wife suggested the caller might be a snipe.

As mentioned in previous columns, the snipe is a real bird despite its reputation as a mythical creature thanks to the rural tradition of the “snipe hunt.” While the calling bird at their home did remind them of a Wilson’s snipe, they were not convinced.

“Is this the right time of year to be hearing one in our area?” Lewis asked in his email. “Is there another bird that makes this kind of winnowing?” Both of his astute questions helped me narrow the possibilities.

In my reply, I did inform Lewis that the Wilson’s snipe, as well as the closely related American woodcock, make their home in the region. The summer season, however, isn’t the best time of year to hear either of these relatively elusive shorebirds. These birds are most vocal at the peak of their breeding season, which usually occurs much earlier in the year.

Photo by Bryan Stevens Lucy, an Eastern screech-owl, is part of an educational program at Brookgreen Gardens in South Carolina that teaches audiences some fascinating information about native wildlife. For instance, despite her small size, Lucy is an adult owl, not a baby.

It was his second question, especially the description of the “winnowing” sound, that got me thinking in an entirely different direction. It also helped that I’ve heard some of these small, nocturnal vocalists at my own home in recent weeks. I suggested that the Chapmans get online and look up the song and other vocalizations of the Eastern Screech-owl.

An adult Eastern screech-owl is usually only between six and nine inches in length. Many people upon first seeing a screech-owl assume it’s a baby owl. On a recent South Carolina trip I made several visits to Brookgreen Gardens near Pawleys Island. On several of these visits I attended the daily educational programs conducted by the zoo staff at the gardens that are designed to introduce visitors to various examples of native wildlife. The presenter usually introduced a couple of animals to the audience. On several occasions, the show featured birds of prey, including hawks and owls.

Two of the shows featured Lucy, an Eastern screech-owl, and people in the audience invariably asked if she was a baby owl. To their astonishment, they learned that Lucy was an adult screech-owl and unlikely to grow any bigger. There are larger owls in our region, including the great horned owl and barred owl. Lucy and her kin must avoid these much larger owls, which would have no hesitation at trying to make a meal of the much smaller owl.

Because of their small size, screech-owls prey on some comparatively small creatures, including insects, small rodents, amphibians and reptiles. The Eastern screech-owl is also a cavity-nesting bird and will accept bird boxes provided by humans so long as the box’s entrance hole is customized to their size.

Photo by Bryan Stevens An Eastern Screech-owl perches among some hemlock branches.

The screech-owl is probably the owl most likely to encounter human beings. It’s an adaptable little feathered predator, fully as at home in the backyard and garden as it is in parks and woodlands. In addition to nesting in cavities, this owl roosts in them during the daytime hours. Look for roosting screech-owls in knotholes of trees or in unoccupied wood duck boxes. Although they come in two color phases — red and gray — both variations are quite capable of camouflage. When perched or roosting, these small owls blend remarkably with their surroundings.

The Eastern screech owl also produces a variety of odd wails and other vocalizations including a distinctive, trembling “whinny” call that is often made when the owl feels curious or alarmed. It’s a wavering, haunting call that is made after dark, most often at the hours closer to dawn and dusk. Imitating the call of a screech-owl or playing a recording is also a trick for getting some shy songbirds to show themselves. Screech-owls are unwelcome neighbors among songbirds, which will flock to this owl’s call and band together to “mob” the predator and try to convince it to depart the immediate area.

In addition to the Eastern screech-owl, the United States is also home to several other small owls, including Western screech-owl, Northern pygmy-owl, Northern saw-whet owl, flammulated owl and elf owl.

After I pointed to the screech-owl as the identity of the unseen caller at the Chapman home, I did receive another email from Lewis. My suggestion of the screech-owl proved correct. “It’s fun having the Eastern screech-owl in our woods,” he wrote back. “It has a beautiful call and most nights it does it for quite awhile.”

Early naturalist and artist John James Audubon painted a family of Eastern Screech-owls.

Screech-owls do make good neighbors. Their prey preferences remove many nuisance insects and rodents from the habitat they share with humans as well as other wildlife. If you’re hearing an odd, winnowing call from the edge of the woods at your own home, there’s a good chance that you have one of these small owls as a neighbor.

Since moving to Laurel Bloomery, the Chapmans have already seen many great backyard birds, including indigo bunting, great crested flycatcher, ruby-throated hummingbird, house wren, black-and-white warbler, pileated woodpecker and chipping sparrow. Now they can also add Eastern screech-owl to the list. Who knows? They may some day also add a Wilson’s snipe to their yard list of birds.
