The 56th annual Elizabethton Fall Bird Count was held Saturday, Oct. 4. A total of 25 observers participated in about 13 parties. The weather was good, with clear skies, no wind and temperatures ranging from 42 to 82 degrees.

This year’s count tallied 120 species, plus two gull species and one Empidonax species of flycatcher. This total is slightly below the recent 30 year average of 124 species, according to compiler Rick Knight The all-time high on this count was 137 species in 1993.

The count is conducted in the Northeast Tennessee counties of Carter, Johnson, Sullivan, Unicoi and Washington.

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

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

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

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

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

Why do owls give a hoot? For many reasons

Leave a reply

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

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

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

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

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

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

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

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

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

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

Joanne Campbell commented on my post.

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

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

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

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

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

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

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

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

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

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

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

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

Local couple comes to aid of injured hummingbird

1 Reply

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Birds boast phenomenal knack for long-distance travel

Leave a reply

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

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

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

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

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

Photo by U.S. Fish & Wildlife Service/Kirk Rogers • The Arctic tern is a world champion among migrating birds.

 

One good tern deserves another

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

Photo by Bryan Stevens • Despite a perceived disadvantage of size, ruby-throated hummingbirds are quite capable of thriving in a giant world.

Size matters less than we think

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

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.

 

Godwits, by Jove!

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

Bryan Stevens • A broad-winged hawk perches in a woodland in the Southern Appalachians.

A fine kettle of hawks

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

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

Traveling in stages

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

Looking for fall migrating birds already underway

1 Reply

A male Wilson’s warbler perches in some branches. Many species of warbler migrate through the region each fall.

Summer’s waning. Just look at the calendar. We’re already approaching the midway point in August.

Birders track the transitions as one season merges into another, knowing that these are some of the best times to seek out birds. Fall migration doesn’t wait for a page to turn on a calendar. In fact, some birds are already on the move. I thought I’d devote this week’s column to some of the birds I hope to observe this fall as a mass migration draws many of our summer residents south toward warmer wintering grounds. In no particular order, here are some of the birds I’m hoping to see this autumn.

COMMON NIGHTHAWKS

The name common nighthawk is a misnomer. The species is not strictly nocturnal and it is certainly not a hawk. It’s actually a member of the nightjar family, which includes such birds as chuck-will’s-widow and whip-poor-will. The nighthawk doesn’t offer a serenade like these relatives, but it does produce a “pent” call that sounds much like an electric buzzer. It’s often the first indication of one of these birds swooping overhead. Nighthawks form impressive flocks, often numbering in the dozens or even hundreds. They are often active in evening hours, but I’ve seen large flocks of these migrating birds in mid-afternoon. August and September are the best time to look skyward to enjoy the spectacle of a large flock of swooping nighthawks as they pass overhead.

I didn’t host any of these colorful birds this spring, so I hope to get another opportunity this fall. The males in their vibrant black-and-white plumage and namesake breast patch of rosy-red feathers are slightly less colorful in the fall. I’ve actually had better luck in autumn hosting these birds at feeders. They love sunflower seeds, so keep your feeders stocked with their favorite foods to increase your chances. Females and young birds look different than adult males, but the heavy beak (the word “gros” is German for large) is a good indicator of their identity. Bird banders netting this species to document information for science can testify that these birds are also capable of a nasty nip at careless fingers with that stout bill.

Bryan Stevens • A pine warbler visits a suet feeder.

WARBLERS

These birds are undeniably at their most gorgeous during spring migration, but many species of warbler retain colorful plumage into the fall season. Young birds, often in a plumage entirely different than adult birds, are responsible for the term “confusing fall warblers.” I’ll be looking for the species that are harder to locate in the spring, including bay-breasted warbler, Cape May warbler, Blackburnian warbler and Tennessee warbler. I’ll also be hoping for a rarity such as cerulean warbler or mourning warbler. I will be sad when the parade of warblers produces a palm warbler or a yellow-romped warbler. These last two species are a sure sign that fall migration’s coming to a close for another season.

WADING BIRDS

Late summer and early fall can also be a fantastic time for scanning rivers, lakes and farm ponds for wading birds. Hurricanes in recent years have even forcibly relocated American flamingos to Tennessee and other unlikely locations. It’s slightly more reasonable to hope for something unexpected like a wood stork or roseate spoonbill. The more likely candidates for observing in the region are great egrets, tri-colored herons and snowy egrets. It’s also a last chance to view green herons before this small species retreats to warmer locations for the coming winter.

Bryan Stevens • A hermit thrush perches on a fence.

THRUSHES

These medium-sized songbirds are typically brown in plumage, often with spotted white breasts. They’re beautiful singers in spring and summer, but they’ve often cut back on their singing by fall. Nevertheless, they form large migrating flocks that will roam autumn woodlands to rest and refuel during short breaks from migrating. Swainson’s thrush is not difficult to find in the fall. This species is named in honor of 19th century artist and ornithologist William Swainson. Like most birders, I will be hoping for the more difficult species like Bicknell’s thrush and gray-cheeked thrush. Knowing their call notes can help alert you to their presence.

There will be a dazzling diversity of our feathered friends on the move this month. The seasonal phenomenon of migration extends into September and October. Pay attention to the visitors in your yards and gardens.

Late summer offers interesting birding opportunities for birders

A pair of Carolina wrens has taken advantage of what was meant to be the temporary storage of some boxes on the front porch to claim the interior of one of the cardboard containers as a nesting location.

In the latter days of summer, usually a lackluster period for birdwatching, there are still some interesting behaviors or actions on the part of our feathered friends to provide some points of interest.

Wrens already have a reputation for nesting in some unusual locations. My introduction to the Carolina wren took place in my childhood when a pair of these wrens nested in an old apron my grandmother used as a bag for her clothespins. Other unusual locations for wren nests that I have found over the years included the interior of a plastic shopping bag hanging from a nail in my garage and an attempt to nest in the exhaust vent for my clothes dryer. I’ve also seen them nest in hanging flower baskets.

Photo by Jean Potter • A Carolina wren creeps along a fence.

The world’s 88 species of wrens are, for the most part, the quintessential “little brown birds,” but that hasn’t kept them from acquiring some interesting and descriptive common names. Some examples include the tooth-billed wren, flutist wren, riverside wren, whiskered wren, happy wren, musician wren, timberline wren, speckle-breasted wren, white-breasted wood wren and giant wren. The last species on the list resides in Mexico and is indeed a “giant” among a family of tiny birds, reaching a length of almost nine inches and weighing all of 1.8 ounces.

I’ve also been monitoring a great blue heron lurking along the creek that flows past my home. A collapsed foot bridge (thanks to Helene) still spans the creek and provided, at least from the heron’s perspective, a means of concealment from my prying eyes when I stepped onto the front porch. The heron ducked under the bridge and slowly stepped downstream, out of sight and presumably what the bird thought would be out of mind. But I tricked the heron, stepping back inside the house and waiting for It to reappear. I stepped into view again and the heron, instead of taking flight, repeated its earlier actions, skirting beneath the bridge and wading downstream. I could probably have continued this game of peek-a-boo, but I felt that I had imposed on the heron long enough. The bird evidently desired to try its luck fishing upstream beneath a shady overhang of branches from trees growing along the creek banks. I stepped back inside, peeked out a window and watched the heron move in a slow, stately manner, but this time the bird headed up the creek.

All herons are skillful anglers, so I am confident that the bird probably managed to catch an unwary frog or fish. As the tallest heron in North America, the great blue heron boasts a diverse diet. These birds, armed with a dagger-shaped bill, excellent vision and quick reflexed, prey on rodents, amphibians, snakes, fish and even small alligators. Basically, a great blue heron will eat anything it can swallow.

Photo by Bryan Stevens • A great blue heron’s quick reflexed and dagger-like bill make it a formidable predator.

Other herons around the world with descriptive names include purple heron, white-bellied heron, black-headed heron, great-billed heron, whistling heron, pied heron and Goliath heron. The latter, as its name suggests, is a giant among herons.

There’s more to report on the birding front. Hummingbird numbers are on the rise again. After the usual summer lull, the resident ruby-throated hummingbirds have raised their profile, visiting daily at feeders as well as blooming flowers. Female hummingbirds have had time to raise their young. In fact, many of the hummingbirds visiting your yards and gardens at this time of year are probably birds born earlier in the season. In a couple of months these young birds will make their inaugural migration across the Gulf of Mexico to reach winter grounds in Central America. Until that time, hang a sugar water feeder, grab a lawn chain and enjoy the hours of no-cost entertainment provided by these feisty, flying gems.

So, although the summer doldrums do make birds scarce at times, just know that they’re still out there. In the meantime, nature offers plenty of other engaing wildlife. During the day, it’s fun to look for butterflies and dragonflies. After dark, there’s always moths and lightning bugs.

Keep in mind, it’s not always the visuals. For instance, the past couple of nights I’ve enjoyed listening to an Eastern screech-owl’s nocturnal serenade with its trembling wailing call that gives this small owl its name.

Carter County Summer Bird Count tallies 117 species

1 Reply

Hans Toom/Pixabay • A couple of Canada warbler got tallied with this year’s Carter County Summer Bird Count.

The Lee and Lois Herndon Chapter of Tennessee Ornithological Society, also known as the Elizabethton Bird Club, held its 32nd annual Carter County Summer Bird Count on Saturday, June 7 with 20 observers in nine parties.

Participants tallied 117 species, which is slightly above the average of 114 species.

Most unusual was a Mississippi kite seen for the first time on one of the chapter’s summer bird count. The kite was seen in the Toll Branch vicinity, according to the count’s longtime compiler Rick Knight. He also indicated that other notable finds included common merganser and red crossbill. In addition, counter found 18 species of warblers.

The list:

Canada goose, 90; wood duck, 8; mallard, 56; and common merganser, 2.

Wild turkey, 13; rock Pigeon, 36; Eurasian collared-dove, 3; mourning dove, 142; yellow-billed cuckoo, 5; chuck-will’s-widow, 4; Eastern whip-poor-will, 8; chimney swift, 55; and ruby-throated hummingbird, 20.

Killdeer, 8; double-crested cormorant, 5; green heron, 2; great blue heron, 10; black vulture, 14; and turkey vulture, 46.

Cedar waxwings provide entertainment as they feast on mulberries

Photo by Jack Bulmer/Pixabay • A cedar waxwings strikes a stately pose on a branch.

Spring turned out to be a rainy season in Northeast Tennessee. As we move into the official summer season as of Friday, June 20, summer’s also looking like it might be wetter than usual.

Rainfall hasn’t stopped the rhythms of the seasons. For instance, two mulberry trees at home have produced a bonanza of ripening berries for our fruit-loving feathered friends.

So far, the main beneficiaries of all this bounty has been the local cedar waxwings. These sleek and distinctive birds have a brown and gray silky plumage, a black mask and a perky crest. Some of the wing feathers show red tips. The similarity of these wing tips to melted drops of wax gives these birds the common name of waxwing.

There’s no absolute explanation of the purpose for these waxy tips. Experts have theorized that the colorful wingtips might help attract mates.

Other birds have competed for access to the berries, including American robins, gray catbirds and at least one scarlet tanager.

Cedar waxwings love their fruit. They’re not quite a frugivore, which is a scientific term for animals that depend mostly on raw fruits for sustenance. The website All About Bird recommends planting native trees and shrubs that bear small fruits, including such species as mulberry, dogwood, serviceberry, cedar, juniper, hawthorn and winterberry, to attract cedar waxwings.

The cedar waxwing has few relatives. Worldwide, there are only two other species: the Bohemian waxwing, of the northern forests of Eurasia and North America; and the Japanese waxwing, found in such northeast Asian countries as Japan, Korea and China.

Although it’s classified as a songbird, the cedar waxwing does’t truly produce a vocalization that anyone would contend qualifies as a song. They are, however, very vocal birds, producing shrill, high-pitched notes as they pass through the upper branches of tall trees.

Early American naturalist and artist John James Audubon painted this pair of cedar waxwings.

As much as the waxwing has a fondness for fruit, it’s also a bird that would have made an excellent flycatcher. Flocks of these birds will often congregate in trees near the edge of a pond, garden or yard — anywhere winged insects might be found in good numbers — in order to hawk insects on the wing. A waxwing will sally forth from a branch, snatch its prey in mid-air, and return to its perch for a quick snack. Dragonflies often feed on mayflies and dragonflies but they will also forage on a wide array of other winged insects.

Waxwings are rather nomadic, coming and going with a maddening unpredictability. They often follow the available sources of food, whether that’s the multitude of flying insects attracted by pond and rivers or a particularly bountiful crop of fruit.

They can form large flocks. I once observed a flock that probably consisted of 100 individuals as they stripped berries in early winter from a holly tree. Adding some comic relief to the scene were two Northern mockingbirds making a futile attempt to disperse the waxwings and thus claim all the berries for themselves. The mockingbirds would chase off a dozen or so birds only for twice that number to descend on the vacated spot in the tree’s branches. It was a losing battle, but I am confident that once they settled down, the mockingbirds managed to enjoy the supply of berries alongside the overwhelming numbers of waxwings.

I’ve enjoyed the friendly flock of waxwings as they’ve feasted on mulberries. The only drawback has been that I am usually observing their antics in late evening when the sun is behind these birds. Fortunately, even a waxwing’s sleek silhouette is still a sight to behold and enjoy.

Black-and-white warbler won’t be confused with other birds

1 Reply

Photo by Hans Toom/Pxabay A black-and-white warbler would be almost impossible to confuse with any other bird.

I’m thinking that most people have probably heard of a “gaggle” of geese or a “murder” of crows as a way to describe a flock of these particular birds. Warblers also have their collective names. A flock of warblers is often referred to as a bouquet, a confusion, a fall, a cord or a wrench of warblers, according to the Birdorable Blog.

I personally like “wrench” of warblers. It has alliteration and describes how these amazing little songbirds can definitely “wrench” one’s attention from other matters. That’s been happening a lot at home. Since arriving in early April, the resident warblers have added their songs to the soundscape that makes the woodlands surrounding my home come alive every morning.

I wrote last week about the sad incident of a male Northern parula killed after an impact with a window. I wondered if I’d have to go the spring and summer season without hearing the excitable little trill of syllables that comprises this warbler’s song. I’m happy to report that less than a week passed before another male Northern parula showed up and began adding his song to the daily chorus. The circle of life continues.

On Saturday, May 3, I got to branch out from the handful of warbler species in residence around my home to warblers in other locations. I birded with Chris Soto, a Johnson City resident and fellow member of the Elizabethton Bird Club, on Holston Mountain and Sycamore Shoals State Historic Park as part of the annual Spring Bird Count conducted by the EBC. Despite some rain while conducting our survey of Holston Mountain, we encountered a variety of warbler species.

We didn’t observe any large warbler flocks, or wrenches, but we did find numerous species, including ovenbird, worm-eating warbler, Louisiana waterthrush, black-and-white warbler, Swainson’s warbler, hooded warbler, American redstart, Cape May warbler, Northern parula, yellow warbler, chestnut-sided warbler, black-throated blue warbler, yellow-throated warbler, black-throated green warbler and Canada warbler.

We added most of these species to the list by hearing them singing their springtime songs, including the “squeaky wheel” of the black-and-white warbler and the loud, ringing notes of the Louisiana waterthrush. If the latter wants to be heard, it is essential that it produce a loud song. The waterthrush resides near rushing mountain streams, which could easily overpower songs projected at a lower volume.

The black-and-white warbler is arguably the most aptly named of all the warblers. Both males and females have glossy black and white plumage. That’s it – there are no other colors present in the bird’s feathers.

The black-and-white warbler breeds in northern and eastern North America. It ranges from the Northwest Territories to the northwest and Newfoundland and Labrador to the northeast, to North Carolina to the southeast and Texas to the southwest. This species is migratory, wintering in Florida, Central America, the West Indies and northern South America down to Peru.

Once arriving for the spring, these warbler go about the business of nesting. The female black-and-white warbler selects a well-hidden nesting location at the base of a tree, rock, stump or fallen log, or under a bush or shrub, according to the website All About Birds. I discovered a black-and-white warbler nest, quite by accident, several years ago. The nest was wedged in a crevice beneath a large fallen pine resting on a steep ridge. Besides being rather inaccessible, I had no wish to disturb the nest so I enjoyed watching the birds through binoculars from a distance.

Photo by Hans Toom/Pxabay • A male black-and-white warbler sings its squeaky wheel song.

In its tendency to hug the trunk of trees as it seeks out insect prey, the black-and-white warbler is similar to unreleased species such as brown creeper and white-breasted nuthatch. In fact, an old common name for this bird was black-and-white creeper. It does venture farther out into a tree than the trunk, however, and will flit among branches as good as any other warbler.

For beginners just getting into the hang of birding, the black-and-white warbler is a dream when it comes to identification. It’s unlikely to be mistaken for any other bird. One good look through binoculars is usually all it takes to recognise the species. There’s no poring over the pages of a field guide for subtle field marks to help when trying to identify the black-and-white warbler. The same is true for the bird’s song, which is very similar in pattern to a squeaky wheel spinning round and round.

Enjoy the springtime and get outdoors and see what feathered friends are winging their way into your neighborhood.

Tiny songbird’s collision with window leaves gap in spring soundscape

Hans Toom/Pixabay • Male Northern paroles are a member of the warbler family. They are amazing vocalists producing an easily recognised trill of a song.

The male Northern parula is a persistent songster once arriving on its nesting territory each spring.

Since arriving in early April, a male Northern parula had been a tireless singer. I often heard the bird as I departed for work each weekday morning and was welcomed home in early evening by the bird’s song.

On April 29, I returned home. I followed my usual routine and dropped off my mother’s newspaper and mail at her home. Unfortunately, on her porch was the lifeless form of the Northern parula. I know it was “my” parula because the bird had been so faithful in its singing. I have not heard the song of a Northern parula in the days following the sad discovery.

Northern parulas sing two different types of songs, according to the website All About Birds. The most common is a rising buzzy trill with a final sharp note. This song rises up and pinches off sharply at the end. The second song has distinct pauses in between bouts of the rising buzzy trill. My parula had mostly sang the song best described as a rising buzzy trill, but it had also practiced at the second version, as well.

The tragic end for this little songster has really put a damper on my enjoyment of the spring season. Unlike many of our birds, this species of warbler has been thriving. Northern parulas are common, and their populations have actually increased by over 1% per year from 1966 to 2019 for a cumulative increase of about 47% according to the North American Breeding Bird Survey.

Bryan Stevens • This Northern parula died after a collision with a glass window.

But the incident is a reminder of the perils that our feathered friends face daily. An article titled “Getting Clear on Birds and Glass,” first published January 14, 2023, by Christine Sheppard and Bryan Lenz brings the detrimental impact glass has had on birds into focus.

The article noted that Smithsonian researches in 2014 attempted to determined how many birds are killed annually due to hitting windows. The study estimated, conservatively, that collisions with glass likely kill between 365 million and 1 billion birds annually in the United States. The authors of the article emphasized that they believe the number is closer to a billion birds, if not more, that die each year from hitting windows and other glass surfaces.

That’s a scary number, but also a testament to the resilience of birds. Of course, all living things have their limits, and we should try to do something to bring down this gruesome toll.

The little parula had struck a large picture window. We have placed decals in the window in an effort to break up the reflection, but the sun has bleached these over the years, and now it is evident they should be replaced. Clouds, sky or vegetation reflected in a window are perceived by birds as the real deal. A screen over a window or hanging strips or other items to break up the reflection will help birds avoid collision.

To examine a database with various possible solutions, please visit https://abcbirds.org/glass-collisions/products-database/

I am hopeful that another Northern parula will visit and find my yard to its liking. I’ve had Northern parulas residing consistently around my home from April to September for many years. The absence of this bird’s song from the daily soundscape has been distressing.

Mack Hayes sent me a message on Facebook to report his first hummingbird arrived on Friday, April 25. “Saw first hummingbird this morning,” he wrote. He noted that he lives on the corner of Oakland Road and Bowmantown Road in Washington County.

•••

Hummingbirds are now back throughout the region. In the past couple of weeks the numbers have increased at my home. I have now seen as many as four hummingbirds at one time, and they duel all day long with each other, chasing each other from one corner of the yard to another. It’s good to have them back.
