Think of the vireos as ‘Plain Janes’ of songbirds

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

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

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

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

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

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

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

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

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

Hooded warbler and its kin bring tropical splash to area woodlands

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

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

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

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

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

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

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

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

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

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

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

Unicoi County summer survey finds 107 bird species

Photo by JudaM/Pixabay.com • Birds that nest at some high elevations, such as this red-breasted nuthatch, thrive at different locations in Unicoi County. A total of six red-breasted nuthatches were tallied on the recent Unicoi County Summer Bird Count.

The Elizabethton Bird Club holds two summer bird counts to supplement other population monitoring efforts on the birdlife of Tennessee. Six years ago, the club launched an annual survey of summer bird populations in Unicoi County.

The sixth annual Unicoi County Summer Count was held Saturday, June 15, with 16 observers in five parties. A total of 107 species was found, which is slightly below the average of 109 species. Unicoi County offers several high elevation species of birds not easily found in the region, according to compiler Rick Knight.

Knight noted that highlights for the count include sharp-shinned hawk, bald eagle, yellow-bellied sapsucker, least flycatcher, warbling vireo, common raven, red-breasted nuthatch, brown creeper, golden-crowned kinglet and hermit thrush. The count also found 18 species of warblers, including Swainson’s, Kentucky, magnolia and prairie.

Photo by Jean Potter • Golden-crowned kinglet is another high-elevation species found in Unicoi County during the summer.

The most common birds found in the count included American robin (241), European starling (224) indigo bunting (147) and song sparrow (146).

Some expected birds could not be found on the day of the count, including ruffed grouse, great horned owl, winter wren, Blackburnian warbler and pine warbler.

I counted with Dave and Connie Irick, Brookie and Jean Potter and Brenda Richards in the Limestone Cove community of Unicoi County. Some of our best birds included yellow-breasted chat, yellow-bellied sapsucker, rose-breasted grosbeak and Swainson’s warbler.

The total for this year’s Unicoi Bird Count follows:

Canada goose, 90; wood duck, 27; mallard, 33; wild turkey, 5; great blue heron, 2; and green heron, 3.

Reader from Utah shares story about pine siskin rescue

PineSiskin-Utah

A recent email reminded me that some of the birds that visit us during the winter range far beyond our yards and gardens here in Northeast Tennessee.

I received an email from Fred Bergold, a reader who resides in Utah.

“This little warbler flew into our window,” Fred explained in his email, which arrived with photos attached. “My wife picked it off the deck and held it for about half an hour.”

The kind treatment worked. “When it got its bearings back, it flew to the top of our Colorado green spruce,” Fred wrote.

Siskin-PairAtFeeders

Photo by Bryan Stevens • Pine siskins feast on thistle seeds at a feeder.

“We feed the local wintering birds black oil sunflower seeds, which many species seem to like,’ Fred continued. “We live in Fruit Heights, Utah, just north of Salt Lake City.”

When I looked at the photos Fred provided, I realized that the bird in question wasn’t one of the warblers but a species of small finch known as a pine siskin. I replied to Fred’s email and offered a quick lesson in distinguishing pine siskins from warblers and other small songbirds.

I informed Fred that siskins usually travel in flocks and that they love feeders with sunflower seeds.

I also shared with him that I’ve gotten to travel to his home state of Utah twice since 2003. Getting to see some western species — American dipper, lazuli bunting, western tanager, violet-winged swallow — while visiting the state produced some memorable birding moments.

Sisken-Spruce

Winters, no matter where one lives, can decrease the variety of bird species one sees on a daily basis. I often find myself hoping for the excitement produced when flocks of “irruptive” finches not often seen in the area expand their range into the region. In addition to pine siskins, birds such as evening grosbeaks, purple finches, common redpolls and red crossbills represent a few of these northern finch species that occasionally stage massive migratory movements, or irruptions, into areas far outside their typical ranges.

These finches are not the only birds to stage these periodic irruptions. The website birdsource.org identifies several non-finch species — red-breasted nuthatch, Clark’s nutcracker, bohemian waxwing, black-capped chickadee and varied thrush — that undertake periodic winter irruptions. Two of these northern finches — the pine siskin and the red crossbill — are sporadic summer residents on some of the higher mountains in our region.

Siskins-OnGround

Photo by Bryan Stevens • A flock of pine siskins carpet the ground beneath some feeders as they forage for food.

These irruptions are not usually motivated by cold or severe weather. The absence of a favored food source on a bird’s normal winter range is usually a trigger for an irruption. Birds, such as pine siskins, will fly farther than normal in a quest for reliable food sources. Not surprisingly, well-stocked feeders often attract their attention.

The pine siskin belongs to a genus of birds known as Spinus, which includes three species of goldfinches and more than a dozen species of siskins, many of them native to Central and South America. Only one species — the Eurasian siskin — is found outside of the New World. Other siskins include the black-capped siskin, hooded siskin, red siskin, black siskin, Antillean siskin and Andean siskin.

GoldfinchBABE

Photo by Bryan Stevens • The American goldfinch is a relative of the pine siskin, and the two species often associate with each other at feeding stations.

Siskins often associate with American goldfinches. In shape and size, the two birds are extremely similar. Unlike goldfinches, however, siskins display extensive streaking on their back and breast. The bill of a siskin is sharp and pointed. Overall a drab brown in coloration, siskins also show some surprisingly bright yellow coloration in their wings and tails. Although sociable, individuals can display some irritable tantrums when competing for prime space at feeders.

Some people quickly discover that a large flock of pine siskins is quite a drain on the daily allotment of feed provided for backyard birds. For such small birds, they have large appetites. Siskins are also extremely tame and can often be approached quite closely. A few years ago during a particularly frigid cold snap, I succeeded in luring a pine siskin to land on my gloved hand, which held some sunflower seeds. Needless to say, it was a very memorable, intimate moment.

In addition to this unusual tameness, siskins are extremely vocal birds. These birds have a shrill trill that sounds almost mechanical to my ears. Large flocks also produce a constant twittering noise as they perch in trees or on feeders.

Next month will offer an opportunity to participate in the annual Great Backyard Bird Count, which is a free, fun, and easy event that engages bird watchers of all ages in counting birds to create a real-time snapshot of bird populations. Recording visiting birds such as pine siskins is an important component of the GBBC. Participants are asked to count birds for as little as 15 minutes (or as long as they wish) on one or more days of the four-day event and report their sightings online at birdcount.org. Anyone can take part in the Great Backyard Bird Count, from beginning bird watchers to experts, and you can participate from your backyard, or anywhere in the world. The 21st annual GBBC will be held Friday, Feb. 16, through Monday, Feb. 19, 2018. Please visit the official website at birdcount.org for more information. I’ll also focus on the GBBC more in upcoming columns, including information about activities planned at a local park.

Bristol’s CBC records low total of species, but still makes some interesting finds

brown-headnuthatch

Photo by SOARnet/Pixabay.com • The brown-headed nuthatch favors stands of loblolly pine, which are not common in the region. A record number of these small nuthatches were found on the recent Bristol TN-VA Christmas Bird Count.

Just before the end of last year, 21 participants gathered to conduct the Bristol TN-VA Christmas Bird Count. Count compiler Richard Lewis noted that the CBC found 71 species and a total of 5,700 individual birds.

“This was the 63rd year the count has been run since 1956,” Lewis posted on Bristol-Birds. “It was the lowest total number of species recorded in 27 years.”

Lewis could not explain the low total of species other than to note that the area doesn’t seem to have the usual influx of wintering birds from up north. In addition, waterfowl numbers were low. “Some species are not coming as far south this year,” he added.

The best find of the count was the discovery of a new bald eagle nest on South Holston Lake. Other noteworthy species recorded were black-crowned night-heron, red-shouldered hawk, merlin and brown-headed nuthatch. The four individuals found represent a new high count for the brown-headed nuthatch on the Bristol CBC. The species had only been seen on the count three other times.

The brown-headed nuthatch is a specialist of pine woodlands throughout the southeastern United States, favoring loblolly-shortleaf pines and longleaf-slash pines. This nuthatch requires standing dead trees for nesting and roosting. They forage for food, however, on live pines. The birds are more abundant in older pine stands.

This small nuthatch is not at all common in the region, but there are some records, including other Bristol records. I’ve had much better luck finding the brown-headed nuthatch during visits to coastal South Carolina or suburban Atlanta in Georgia. In these southern locations, it can be a quite common bird.

Spring-Nuthatch

Photo by Bryan Stevens • In some areas, brown-headed nuthatches are feeder visitors. These small nuthatches are specialists that favor stands of loblolly pine.

These small birds will occasionally forage close to the ground, but they are often in the upper branches of pine trees. Their presence is often revealed by their call, which sounds amazingly like a squeeze toy. They produce their “squeaky toy” call persistently when agitated or curious. Brown-headed nuthatches often associate with mixed flocks in company with Carolina chickadees, tufted titmice, pine warblers and other small songbirds. White-breasted nuthatches and red-breasted nuthatches are more likely visitors to yards and gardens in the region.

Participants in the CBC included Ron Carrico, Rob Biller, Rack Cross, Angela Cross, Robert Hunter, Terry Hunter, Rick Knight, Roy Knispel, Cade Campbell, Larry McDaniel, Ruth Clark, Mary Clark, Randy Smith, Ron Harrington Sam Evans, Kevin Hamed, Rick Phillips, Adrianna Nelson, Michelle Sparks, Richard Lewis and Phillip Lewis.

Glade Spring CBC finds 63 species

A Christmas Bird Count is also conducted annually in Glade Spring, Virginia. This year’s Glade Spring CBC took place Dec. 27 and found a total of 63 species and 6,696 individual birds. The total and individual count both dropped slightly from last year’s count, which found 71 species and 6,891 individual birds. Twenty-three people participated on the 2018 Glade Spring CBC.

Count compiler Ron Harrington noted that one new species — a common loon found on a private pond just off Old Saltworks Road — made its Glade Spring CBC debut. Six common mergansers, a new count circle high, were found on the North Fork of the Holston River. A single common merganser was found in that same river last year for the first time.

Other highlights noted by Harrington included 48 red-tailed hawks (a new high count total), 10 hairy woodpeckers (tying the record high) and three palm warblers, which represented a new high count for this warbler species. The CBC also recorded a high count for wood ducks with seven individuals being found. Other notable finds include swamp sparrow, brown creeper, brown thrasher, loggerhead shrike, winter wren, hermit thrush, Eurasian collared dove and common grackle.

Christmas Bird Count makes for fun outing during the holiday season

carolinawren-snow

Photo by RetyiRetyi/Pixabay.com • Carolina wrens are small, inquisitive and hardy songbirds. The recent Elizabethton Christmas Bird Count found a record number of this wren during its annual survey of bird populations.

I participated in the 76th consecutive Elizabethton Christmas Bird Count, which was held Saturday, Dec. 15. This annual count is one of the oldest Christmas Bird Counts in the region, as well as in Tennessee.

I was one of twenty-eight observers in six parties. Together, we tallied 77 species, which is above the recent 30-year average of 72 species. The all-time high was set last year when 85 species were counted on this annual survey.

Osprey-LYNNValley

Two species — osprey and orange-crowned warbler — were found on this CBC for the first time. Longtime count compiler Rick Knight observed that one noticeable difference between last year’s count and the 2018 Elizabethton CBC was the number of ducks. Last year’s CBC yielded 13 species, but only six species of ducks were found this year.

Knight also noted that a record number — 139 — of Carolina wrens was spotted by CBC participants.

A single bald eagle was found, but it was enough to continue a recent trend. This eagle has appeared for 19 of the last 20 on the Elizabethton CBC. Counts more than 20 years ago rarely produced any bald eagles.

A single red-shouldered hawk represented a good find since this hawk has only been found on six of the previous 25 years. A single merlin represented an even more exceptional find for this CBC. Merlin has been represented only two times in the last 25 years for this particular count.

Red-shoulderHawk

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

Knight noted that two shorebirds — killdeer and Wilson’s snipe — have experienced a steady decline in making this annual count. This year’s count produced only a single killdeer and snipe.

Knight speculated that low numbers of cedar waxwings and American robins on this year’s CBC probably indicates a poor wild fruit crop. These two species depend heavily on fruit to supplement their diet during the winter months.

Chipping sparrow has now been found for 15 straight years, but had only previously been reported six times in the first 50 years of the history of the Elizabethton CBC.

Without fail, some species manage to evade counters. According to Knight, some of the conspicuous misses this year included ruffed grouse, common loon and barred owl.

Mom-Grouse

The Elizabethton Bird Club has been holding its annual Christmas count in Elizabethton, Tennessee, since 1942. The tradition of the Christmas Bird Count dates back much farther and originates from a less than bird-friendly custom. According to the National Audubon Society’s website, so-called sportsmen in the late 19th century would conduct a “Side Hunt,” a rather blood-thirsty Christmas custom that saw hunters competing to see who could score the largest amount of feathered and furred corpses.

The annual holiday bird survey may even have arisen from an earlier custom with roots in Europe that came to the United States of America with early colonists. The “Side Hunt” has some similarity to a peculiar celebration in Ireland and other European countries known as “Wren Day” or “Hunt the Wren Day.” The event was conducted the day after Christmas, the date of Dec. 26 being consigned as Saint Stephen’s Day. By the 20th century, the hunt consisted of tracking down a fake wren carried atop a decorated pole. Crowds would parade through towns in masks and colorful attire. These groups were referred to as “wren boys.”

Whether or not the “Side Hunt and “Wren Hunt” shared any connections, it was a huge step forward for conservation when preeminent ornithologist Frank M. Chapman proposed a new holiday tradition. His radical idea was to count birds during the Christmas season rather than hunting and killing them

The Christmas Bird Count is now conducted each year on dates between Dec. 14 and Jan. 5. The first CBC took place in December of 1900 with 27 observers participating at 25 locations in the United States and Canada. Fifteen of the counts were conducted in the northeastern United States from Massachusetts to Philadelphia. Results from that first count in 1900 didn’t truly reflect the diversity of North America’s birds, but they were nonetheless interesting. The Greater Boston CBC boasted only one participant and only found 17 species. However, some of those species included such good birds as American tree sparrow, brown creeper, Northern shrike and Northern bobwhite.

For me, the Christmas Bird Count is a fun holiday outing with friends. There’s also satisfaction in knowing the results gathered from these nationwide counts will also contribute to the body of citizen science that helps experts determine the status of our feathered friends.

Yellow-rumped warblers are wild about poison ivy berries

WARBLER

Photo by Edbo23/Pixabay.com • The yellow-rumped warbler is one of the few warblers that attempts to reside in the region during the winter months. Switching from a diet of insects to one of fruit and seeds helps the birds manage to find enough to eat during the lean months. This species is particularly fond of poison ivy berries.

 

November and December are bleak months for birders as we experience a bit of a letdown after the joys of fall migration. Many of the favorite birds that spend the summer months with us have departed and will not return until spring. Hummingbirds, tanagers, vireos and most warblers, despite a few lingering individuals, have left the scene.

I really feel the pinch since warblers are one of my favorite families of birds. In northeast Tennessee, southwestern Virginia and western North Carolina, there are only three warblers that bird enthusiasts are likely to see in the winter. The yellow-rumped warbler is by far the most common winter warbler, but palm warblers and pine warblers are also occasional winter residents. A few other warblers are occasional stragglers, attempting to eke out a living during the cold months. For instance, I’ve seen a few common yellowthroats during the winter over the years

Yellow-RUMP

Photo by Edbo23/Pixabay.com • During the winter months, a yellow-rumped warbler is a dull bird in mostly brown and gray plumage except for the rump patch of bright yellow feathers that provides the bird its common name.

With the exception of the yellow-rumped warbler, however, the chances of enjoying warblers during the winter are rather slim. At least the yellow-rumped warbler is common and I encounter flocks of these birds on most occasions when I walk woodland trails in the region any time from November to April.

Until 1973, the yellow-rumped warbler was divided by scientists into two distinct species: the myrtle warbler in the eastern United States and Audubon’s warbler in the western United States. During a visit to Salt Lake City, Utah, in 2003, I saw my first and only “Audubon’s” warbler. This western counterpart is more colorful than the version birders know so well in the eastern half of the country. In addition to yellow plumage on the rear and flanks, the Audubon’s warbler also boasts a yellow crown and a yellow throat patch. Otherwise, the two birds are remarkably similar in appearance.

Of course, it’s the creamy yellow rump patch — looking like a small pat of butter — that gives this species its common name. Birders have adopted another nickname for the species, often referring to them simply as “butter-butts.”

There is now some discussion in scientific circles of dividing the species into not two distinct species, but four. The other two species would be the black-fronted warbler of mountains in Northern Mexico and Goldman’s warbler, which resides in Guatemala. I wouldn’t mind seeing Audubon’s warbler resurrected as a full species, since it would place an additional species on my life list of birds seen. In addition, it seems fitting that we have at least one bird that honors the name of the famed naturalist and painter John James Audubon.

The scientific name for the yellow-rumped warbler is Setophaga coronata, which are terms derived from ancient Greek that when roughly translated mean “crowned moth-eater.” Like most warblers, the yellow-rumped warbler is fond of insects, but there’s another food source these birds turn to during times of scarcity.

So, how does a warbler make it through the winter season in the region? After all, most warblers exist on a diet heavy on insects and other small invertebrates. The yellow-rumped warbler, however, supplements its diet with different seasonal berries, including juniper berries, Virginia creeper berries and dogwood berries. They also feed on berries from one unlikely source. These birds love to gorge themselves on poison ivy berries that, fortunately, produce no ill effects. I’ve long noticed that many of the trails I enjoy walking during the winter season wind through woodlands overrun by poison ivy. Of course, by eating the berries, the warbler also help spread the noxious vines.

The yellow-rumped warbler is not the only bird known to feed on poison ivy berries. Other birds seen eating these berries include Northern flickers, bobwhites, Eastern phoebes, Cedar waxwings, tufted titmice and American robins. White-tailed deer show a preference for dining on poison ivy leaves over other types of vegetation. The berries are high in fat and calories, which makes them an ideal food source for creatures with high metabolisms like songbirds. The berries also ripen in fall and early winter when many other types of berries are scarce. While it is best for humans to avoid contact with this plant, it is a valuable fall and winter food source for wildlife.

While the yellow-rumped warbler is quite capable of dealing with some frost and snow, more than half of the world’s warblers live in more tropical climates outside the borders of the United States and Canada. Not all yellow-rumped warbler attempt to tough out winter conditions in the United States. Some do migrate to the tropics, where they utilize a variety of habitats, including mangroves, thorn scrub, pine-oak-fir forests and shade coffee plantations.

All warblers are exclusively New World bird species. The family numbers about 120 species. Some of the descriptively named species of warblers not seen within the United States or its northern neighbor include citrine warbler, white-striped warbler, black-crested warbler, pale-legged warbler, buff-rumped warbler, golden-bellied warbler and black-eared warbler.

During your next woodland stroll, keep your eyes peeled for small brown birds in the branches of nearby trees. If the last thing you see before they dive for cover is a bright yellow rump patch, you’ll know you’ve observed a yellow-rumped warbler.
