Restless robin flocks signal spring’s approach

When I posted Jan. 29 on Facebook about seeing my first flock of American robins in 2021, I didn’t anticipate the avalanche from other observant bird enthusiasts.

Priscilla Gutierrez commented on seeing about 30 robins in a field along Limestone Cove Road in Unicoi.

“They don’t come to the feeders,” Priscilla noted. “It was wonderful to see them.”

Alice Torbett in Knoxville shared that she saw her first flock of robins about two weeks ago when they swooped in to harvest berries from the holly tees at her Knoxville home. “They were very considerate to wait until after Christmas,” Alice wrote.

Erwin resident Brenda Marie Crowder commented that “tons of Robins are eating my holly berries right now. With snow dropping and all.”

Jonesborough resident Nan Hidalgo reported that she had five robins in her yard on a recent Friday afternoon.

Christine M. Schwarz in Alexandria, Virginia, shared her own sightings.

“Three weeks ago there was a large flock at Mount Vernon,” Christine wrote in a comment to my post. “I have seen a smaller group over here by Fort Belvoir, too. I can’t believe they’re migrating now — more like wintering over.”

Byron Tucker, who lives in Atlanta, commented, “The other day, I saw a flock of robins and blackbirds mixed together.”

Dee Obrien, formerly of Elizabethton, Tennessee, but now living in Florida, lamented the timing of the robins. “They always seem to come back to soon, poor little things,” she wrote. “It is too cold.”

Becky Boyd shared her own experience with robins. “I’ve had dozens here in Knoxville,” she said. “They all recently left, except one loner who is terrorizing the bluebirds and attacks them at the feeders.”

Erwin resident Donna Rea, and a former co-worker at The Erwin Record, posted a question to my Facebook robin discussion.

“What do robins eat this time of year?” Donna asked. “Will they eat out of our feeders if the ground is frozen and they can’t find a hibernating worm?”

I suggested in my reply that robins might eat suet at feeders, as well as fruit. More likely, the restless robins in the region are probably scouring the countryside for holly trees with berries. Of course, robins are omnivorous in their appetite and would gladly take an earthworm if they could coax one out of the chilly ground.

South Carolina resident Catherine Romaine Henderson simply posted an optimistic comment on my robin post. “Please tell me spring is coming!”

The American robin is indeed widely held to be a harbinger of spring. Furthermore, the robin is a popular American bird. In fact, this bird has been designated the official state bird by Wisconsin and Michigan.

In truth, many robins forego migration to endure a few months of cold weather. Their ability to shift their diet from earthworms and insects to fruit and feeder fare helps robins eke out a living. Robins remain an abundant bird but their fondness for co-existing with humans can leave them vulnerable to pesticides applied to lawns and gardens.

According to the website, “All About Birds,” the American robin nests three times a year. On average, however, only 40 percent of robin nests succeed at fledging young. Even once out of the nest, young robins are vulnerable. The website estimates that only 25 percent of each year’s fledged robins will reach November. So, the young robins that join some of the large flocks people are seeing in the region are birds that have beaten the odds.

Photo by Bryan Stevens • Returning American robins, prominent in lawns and gardens during their annual spring migration, will soon turn their attention to nesting duties.

Even the robins that do depart the region each fall don’t migrate far. Many robins that spend the summer in Canada or the United States only migrate as far as the Gulf States, southern Florida, southern California, Baja California and Mexico.

The American robin is a large bird in the thrush family, which in North America also includes such birds as Eastern bluebird, wood thrush, and Townsend’s solitaire.

In the British Isles, the European robin is simply known as “robin” or “robin redbreast.” When the first English colonists arrived in New England and other parts of colonial-era North America, they took pleasure in finding that some of the birdlife in the New World resembled familiar birds from their homeland. The red-breasted American robin looked like the bird they knew in the Old World as “robin,” which motivated them to name the New World bird “robin,” as well.

Other than the red breast, however, the two robins are not all that similar. The American robin is the larger of the two birds. Further separating these two birds is the fact that the European robin is not a thrush but rather a member of the family of Old World flycatchers.

Photo by Bryan Stevens • While American robins like fruit when its available, they also spend a lot of time feeding on earthworms and insects.

In some ways, the two robins are similar. Both are fond of earthworms, spending a great deal of their time on the ground foraging for worms. They will also follow human gardeners at their work, waiting patiently for the followed person to disturb the soil with a spade or hoe and expose earthworms for the waiting bird. They are also rather tolerant of humans and have learned to make their own homes close to human dwellings.

Some of the British transplants to North America must have felt homesick for familiar things because several unsuccessful attempts were made to introduce the European robin to the United States and Canada. European robins introduced in New York and Oregon failed to gain a foothold, unlike the introduction of such alien birds as the house sparrow and European starling.

On a few occasions, our American robins have overflown their destinations and ended up in the United Kingdom. For instance, an American robin became a first for London birdwatchers when one was found in that nation’s capital city in March of 2006. Whether of the European or American persuasion, robins have long been a favorite of birdwatchers and nature enthusiasts.

They have even adapted to take food at feeders. If you’d like to try your luck at attracting robins to feeders, know that they like their sunflower seeds hulled. They will also eat mealworms, fruit, peanut hearts and suet. Robins prefer to feed on the ground or on an open platform feeder.

Robins are such friendly and engaging birds. If we can have them near us for 12 months of the year, who’s going to complain?

 

Watch for wintering kestrels in open habitats

 

Photo by reitz27/Pixabay.com • While one of the smaller falcons, the American kestrel is also one of the this family of raptors more colorful members.

I enjoyed a drive through Limestone Cove in Unicoi, Tennessee, on the afternoon of the next-to-the-last day of 2020. In addition to finding a total of 13 Eastern bluebirds, I saw an American kestrel perched on utility lines near Bell Cemetery. The sighting was the first I’ve had of a kestrel so far during the 2020-21 winter season. Over the years, the cemetery and adjacent fields have been a reliable location for finding this small falcon during the winter.

The American kestrel, although present throughout the year in the region, is somewhat more prominent during the winter months when kestrels from farther north migrate into the region. However, this falcon also nests in the region and can be found at any time of the year in suitable habitat, which is usually open countryside.

The American kestrel is a small member of the falcon family, which includes such relatives as merlin, peregrine falcon and gyrfalcon. All falcons, regardless of size, share a similar aerodynamic design that includes sleek, streamlined bodies and long, slim wings which taper to pointed tips. They fly with rapid wingbeats and are capable of swift flight.

Photo by PBarlowArt/Pixabay.com • An American kestrel uses a rock outcrop as a convenient perch.

The male American kestrel is a colorful bird. He shows a rusty back with some black barring, a rusty tail and steel blue-gray wings. The female kestrel is brownish with black barring on her back and tail. She also shows a buff-colored wash streaked with brown on her under- parts. Both sexes show a strong facial pattern marked by two black “sideburns” on the side of the face.

The American kestrel has long been one of my favorite raptors. They’re seldom as skittish as many other raptors and will permit close observation. Formerly known by the name “Sparrow Hawk,” the American kestrel does not feed entirely on other birds. In fact, a large part of this small falcon’s diet includes rodents and insects.

In its nesting preference, the American kestrel is unusual among other native falcons and hawks. Kestrels nest in cavities, including abandoned woodpecker holes and nest boxes provided by humans.

Photo by Bryan Stevens • An American Kestrel uses a fence post for a perch.

Like many raptors, the American kestrel likes to hunt from a perch, swooping down on unsuspecting prey. The kestrel, however, is also capable of hovering, a type of flight that only a relatively few birds, including the belted kingfisher and the ruby-throated hummingbird, are capable of performing.

The falcons comprise a family of birds with a long history with humans. The sport of falconry, although not as widely practiced today, long ago became associated with royalty and nobility. In fact, falconry has been called “the sport of kings.” The sport basically involved hunting prey, usually other birds, with birds of prey such as falcons. As a pastime, falconry never became as popular in the United States as in other parts of the world.

There are more than 60 species of falcons found worldwide. While the peregrine falcon’s endangered status became well-known in the United States, other falcons have been threatened with extinction. The Mauritius Kestrel once dwindled to a population of only six individuals. Today, the population, due to intensive human effort, has greatly recovered.

Other members of the falcon family can be found in the region, including the peregrine falcon and the merlin. Other falcons in North America include the prairie falcon and the Aplomado falcon. Worldwide, some of the more descriptively named falcons include spotted kestrel, rock kestrel, greater kestrel, lesser kestrel, red-footed falcon, red-necked falcon, sooty falcon and brown falcon.

Twenty-five years ago this week, dark-eyed junco provided inspiration for first column

I wrote my first bird column on Sunday, Nov. 5, 1995, which means this weekly column is marking its 25th anniversary this week. This column has appeared over the last three decades in a total of six different newspapers, which I regard as a personal achievement, as well as an accomplishment for our feathered friends. It’s on their behalf that I pen these weekly efforts to promote conservation and good will toward all birds. I have also posted the column as a weekly blog posting since February of 2014 at ourfinefeatheredfriends.wordpress.com.

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

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

Even as I write my silver anniversary column for “Feathered Friends,” local weather forecasters are predicting the winter’s first hard freeze. This prognostication of approaching winter weather is a perfect time to dust off this week’s column, which is a revision of the first bird column I ever wrote. This column focused on a common visitor to yards and feeders during the winter months. In fact, dark-eyed juncos should be returning to the region any day. Here, with some revisions I have made through the years, is that first column.

•••••

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

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

Most people look forward to the spring return of some of our brilliant birds — warblers, tanagers and orioles — and I must admit that I also enjoy the arrival of these birds. The junco, in comparison to some of these species, is not in the same league. Nevertheless, the junco is handsome in its slate gray and white plumage, giving rise to the old saying “dark skies above, snow below.”

Photo by Bryan Stevens / A Dark-eyed Junco visits a hanging feeder.

Just as neotropical migrants make long distance journeys twice a year, the junco is also a migrating species. But in Appalachia, the junco is a special type of migrant. Most people think of birds as “going south for the winter.” In a basic sense this is true. But some juncos do not undertake a long horizontal (the scientific term) migration from north to south. Instead, these birds merely move from high elevations, such as the spruce fir peaks, to the lower elevations. This type of migration is known as vertical migration. Other juncos, such as those that spend their breeding season in northern locales, do make a southern migration and, at times, even mix with the vertical migrants.

During the summer months, a visit to higher elevations mountaintops is almost guaranteed to produce sightings of dark-eyed juncos. Juncos may nest as many three times in a season. A female junco usually lays three to six eggs for each nest, which she constructs without any assistance from her mate.

Photo by Bryan Stevens • Dark-eyed junco nests on high mountain slopes during the summer month. This dark-eyed junco was photographed at Carver’s Gap on Roan Mountain during the summer nesting season.

Juncos are usually in residence around my home by early November. Once they make themselves at home I can expect to play host to them until at least late April or early May of the following year. So, for at least six months, the snow bird is one of the most common and delightful feeder visitors a bird enthusiast could want.

 Juncos flock to feeders where they are rather mild-mannered — except among themselves. There are definite pecking orders in a junco flock, and females are usually on the lower tiers of the hierarchy. Females can sometimes be distinguished from males because of their paler gray or even brown upper plumage.

Since juncos are primarily ground feeders they tend to shun hanging feeders. But one winter I observed a junco that had mastered perching on a hanging “pine cone” feeder to enjoy a suet and peanut butter mixture.

Photo by Ken Thomas • A dark-eyed junco perches on some bare branches on a winter’s day.

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

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

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

Flocks of red-winged blackbirds, other sightings, could signal winter’s end

Photo by JudaM/Pixabay.com • Feeders are a good way to tempt red-winged blackbirds closer for great views. Males are exceptional in their glossy black plumage with red wing patches accented by a hint of yellow. Females are brown and striped, giving them a similar appearance to large sparrows.

 

H. Lea Jones, Jr. of Bristol, Virginia, wrote to me after seeing my post about pileated woodpeckers a few weeks ago.

“I read with interested your story about this woodpecker,” Lea wrote in an email. “I have been keeping up feeding the birds, which both of my now deceased parents loved to watch, outside the large kitchen windows of their home which I inherited. One day, a couple of years back, while manning the chair and watching the birds, I was startled to see two of these woodpeckers hanging from my extra large suet cage. There was one on each side. Maybe a male and a female?”

Photo by Mike Dobe/Pixabay.com • A pileated woodpecker visits a suet feeder.

Lea noted that the two woodpeckers stayed at the suet for maybe 30 seconds. “I was shocked to see these huge birds and only could assume, at the time, they were woodpeckers. Just very beautiful birds!”

After a little research, Lea discovered the identity of the visitors. “And now I know the ‘sound’ in the wooded area behind the house,” Lea wrote. I had also described the sound in my post.

“Nothing like it I’d ever heard before,” Lea wrote. “Since reading your article, I now realize what a rare sight I have been blessed with. It was truly an amazing sight indeed.”

Dr. John Brenner sent me an email recently about an unexpected sighting at his home in Abingdon, Virginia, on Thursday, Feb. 13, around 5 p.m.

“I saw a Baltimore oriole in my back yard,” he reported. “It was sitting on a fence then flew over to my feeders where it walked around under them.”

He explained that he lives in the heart of Abingdon and has been living at his current address for about three and a half years. “This is the first time I have seen this bird,” he said. “I thought it was unusual.”

Photo by USFWS • Baltimore orioles, like this male, are members of the blackbird family, making them relatives of species such as Eastern meadowlarks, brown-headed cowbirds, common grackles and red-winged blackbirds.

Winter sightings of orioles are rather unusual, but they are not unheard of. The North Carolina Birds website details the emerging phenomenon of wintering orioles.

“Until the 1960s, it (Baltimore oriole) essentially did not winter in the United States, but with milder winters and people putting out oranges and peanut butter on their feeders, and not just various seeds and suet, a number of orioles started wintering from North Carolina to Florida,” according to a profile of the species. Straying into Virginia would certainly not be out of the question, although Baltimore orioles are usually expected in southwest Virginia and Northeast Tennessee from April to October.

In the last couple of weeks, large flocks of red-winged blackbirds have been making stops at my home. The largest flock numbered about 50 individual birds. Red-winged blackbirds are often considered harbingers of spring, but these birds arrived with some of the recent wintry weather that arrived in February.

Photo by Bryan Stevens • A male red-winged blackbird sings to attract mates and ward off rivals.

I’ve long associated red-winged blackbirds with early spring. I also had a single red-winged blackbird make a one-day visit earlier in February during a snowstorm. Those February visitors are the vanguard of large numbers of red-winged blackbirds that return in impressive numbers every March. The blackbirds arriving now behave much differently than the quiet, shy ones that often make brief visits to feeders during late winter snowstorms.

The showy and loud red-winged blackbirds made themselves at home at my fish pond and adjacent stands of cattails, producing quite a commotion. “The kon-ke-ree song of the male red-winged blackbird is a sure indication that spring is on the way,” according to a profile of the species located at the Tennessee Watchable Wildlife website. At this time of year, the male red-winged blackbirds seek elevated perches to display and vocalize.

The male red-winged blackbirds is a very aptly named bird. Glossy black males sport red wing patches that are often trimmed with a narrow band of yellow feathers. By contrast, female red-winged blackbirds are mostly brown birds that could easily be mistaken for large sparrows. Both sexes have sharply pointed bills.

Photo by Bryan Stevens • Red-winged blackbirds arrive as a noisy flock on a wintry February evening.

After I posted on Facebook about the sightings of the red-winged blackbird flocks, Rita Schuettler, a fan of these birds and a resident of Elizabethton, Tennessee, asked whether these flocks were unseasonably early.

Photo by Lintow/Pixabay.com • Female red-winged blackbirds could easily be mistaken for a large sparrow.

I told Rita in a subsequent post that a friend in Atlanta has informed me that he began seeing the blackbird flocks in his neighborhood a couple of weeks ago. So they are right on time for make their appearance in Northeast Tennessee. Laura Evans Barden also posted on my Facebook page that she has been seeing red-winged blackbirds in recent weeks, as well as more common grackles and European starlings.

Red-winged blackbirds are fond of wetlands. Any marsh, damp field or flooded pasture is likely to attract a few resident red-winged blackbirds. Females choose nesting locations in cattails or other marsh vegetation. She usually lays three or four eggs. Although she does receive some help from the male, most of the responsibility for raising the young is left to her.

There is a reason that male red-winged blackbirds are not always quite as engaged in feeding and tending their young. Male red-winged blackbirds are often polygynous, which means that males will often court multiple mates. His time is often occupied defending females and their respective nests from the advances of other male red-winged blackbirds.

Other relatives of the red-winged blackbird in the United States include the tricolored blackbird found along the Pacific Coast and the yellow-headed blackbird resident in wetlands west of the Great Lakes. Rusty blackbird, common grackle and brown-headed cowbird are other species of blackbirds found in Tennessee, Virginia and North Carolina.

American wigeon also known by name ‘baldpate’

Wigeon-TimMcCabe

Photo by Tim McCabe/U.S. Fish & Wildlife Service • This male American wigeon shows the white head patch that gives this duck its other common name of “baldpate.” In this photograph, a female wigeon rests near her mate while a male redhead, a species of diving duck, swims in the background. This duck nests in season wetlands in the American midwest.

Erwin, Tennessee, resident Pattie Rowland recently asked my help identifying some ducks she had photographed at the pond at Erwin Fishery Park. She already suspected the ducks in her photo were American wigeons, but she wanted confirmation.

The ducks were indeed wigeons, which are classified with the “dabblers” instead of the “divers,” which are two broad categories for describing the wild ducks likely to occur throughout North America. Dabblers feed mostly near the surface of the water, foraging on everything for aquatic insects to roots and tubers. The “divers,” not surprisingly, dive into the depth to pursue fish, mollusks and other aquatic prey.

“This was my first time to see them,” Pattie noted in a Facebook message. I congratulated her because I know how exciting a new observation of a bird can be.

Wigeon-RoyLowe

Photo by Roy Lowe/U.S. Fish & Wildlife Service • A male American wigeon looks quite at home swimming on a small pond. Wigeons belong to ducks that are classified as “dabblers” and “puddle ducks.”

It’s not been an exciting winter for ducks in the region. Other than some redheads and buffleheads back in November and early December at the start of the winter, the wigeons are the only wild ducks of interest that I’ve observed at the pond.

The U.S. Fish and Wildlife Service released its report this past summer on 2018 Trends in Duck Breeding Populations, based on surveys conducted in May and early June of 2018 by FWS and Canadian Wildlife Service.

Overall duck numbers in the survey area remained high, according to the report. Total populations were estimated at 41.2 million breeding ducks in the traditional survey area, 13 percent lower than last year’s estimate of 47.3 million but 17 percent above the long-term average. The projected mallard fall flight index was estimated at 11.4 million birds, down from the 2017 estimate of 12.9 million.
“The dip in the population for prairie-breeding puddle ducks is not unexpected and by no means unprecedented given that conditions on the prairies this spring were drier than last year,” said DU Chief Scientist Tom Moorman. “As a result, 2018 populations dropped accordingly. However, populations of all key species except northern pintails and scaup remain above long-term averages. This year’s breeding population decline is a reminder of the need to sustain the capacity of breeding habitats, particularly in the prairies as we go through natural variation in wetland conditions. Waterfowl populations are adapted well to short-term swings in habitat conditions, but we must continue to guard against the long-term loss of prairie breeding habitat.”

Early naturalist and artist John James Audubon painted this pair of American wigeon, a duck for which the male has earned the name “baldpate” for a distinctive white crown patch.

American wigeons, however, bucked the trend of some of the other prairie-breeding puddle ducks and showed a slight rise in overall numbers. The wigeon breeding population was estimated at 2.8 individual ducks, according to the survey. Wigeons beat their long-term average, which rests at 2.6 million.

The American wigeon can be found all over North America. Their breeding grounds stretch from Alaska across the tundras of Canada all the way to the Atlantic Ocean. American Wigeons can be found in their wintering habitats from the American Northwest to central Mexico, from the southern prairie pothole region through the Gulf Coast and from New York to the Bahamas close to the Atlantic shoreline. American wigeons are also common winter visitors to Central America, the Caribbean, northern Colombia, Trinidad and occasionally Venezuela

Wigeons are aquatic grazers and forage on grasses and sedges in wet meadows and pastures. The American wigeon’s diet has a higher proportion of plant matter than the diet of any other dabbling duck.

It’s also called the “baldpate” for the same reason our national bird is known as the “bald” eagle. A white patch on the forehead reminded early naturalists of a bald man’s head in much the same way that our national bird earned the term “bald” eagle because of its own white head. Further, the word “bald” is thought to derive from an archaic word in Middle English meaning “white patch,” from which the archaic definition “marked or steaked with white” is drawn.

The origins of the term “wigeon” are a bit murkier. According to Merriam-Webster Dictionary, the first known use of “wigeon” dates back to 1508, and other sources suggest that the term perhaps was derived from a French/Balearic term meaning “a kind of small crane.”

gadwalls-937033_1920

Photo by Coffee/Pixabay.com • Gadwalls are close relatives of American wigeon.

There are two other species of wigeons — the Eurasian wigeon of Asia and Europe and the Chiloé wigeon of South America. Wigeons belong to the Mareca genus of dabbling ducks, which also includes gadwall and falcated teal.

While female American wigeons produce a rather raspy quacking sound, wigeons more typically produce a vocalization when excited that sounds like “whew, whew, whew.”

Some ducks have become associated with certain bodies of water in the region, and the American wigeon is no exception. In addition to the pond at Erwin Fishery Park, there have been reports of American wigeons this winter from a large pond adjacent to the campus of Northeast State Community College in Elizabethton, Tennessee, as well as on the weir dam at Osceola Island Recreation Site in Bristol. Hooded mergansers have wintered in large numbers at Middlebrook Lake in Bristol. Hundreds of buffleheads have wintered at Wilbur Lake near Elizabethton, Tennessee, for decades. March and April, being periods of transition as winter changes into spring, could bring migrating ducks to the region’s ponds, lakes and rivers. Keep your eyes open and you could be surprised by what you find.

 

 

Virginia woman hosting wintering ruby-throated hummingbird

female-Hummer

Photo by Mariedy/Pixabay.com • The ruby-throated hummingbird is the expected hummingbird in the eastern United States spring through fall. These birds are rare winter visitors, however, which makes the one living in a yard in Fall Church, Virginia.

I have been corresponding by email with Ellen Haberlein since around Thanksgiving of last year about a hummingbird that is wintering at her home in Fall Church, Virginia, which is located only a few miles from Washington, D.C.

The hummingbird’s presence has brightened the winter season for the Haberlein family since it showed up in late October of 2018.

Through the years, I have seen several of these seemingly out-of-place hummingbirds. Some of them remain at their host’s feeders for a brief stay of a few days or a couple of weeks, but some of these hummingbirds have extended their stay for several months, lingering throughout the winter months before eventually departing in February or March.

The big question is: are these hummingbirds truly lost and out of place? The answer, based on everything I have managed to learn, is that these hummingbirds are precisely where they want to be. For still unknown reasons, some of these western hummingbirds make a migration swing through the eastern United States.

Many of the visiting winter hummingbirds turn out to be rufous hummingbirds, which is a species native to the western United States. The bird visiting Ellen’s feeder, however, is a ruby-throated hummingbird. In the summer months, the ruby-throated is the expected species of hummingbird in the eastern United States. In the winter months — not so much. However, in some regions in Virginia, as well as along the Gulf Coast, a few ruby-throated hummingbirds are attempting to overwinter.

The rufous hummingbird has basically become an expected winter visitor with a few reports being received each winter. I have observed Rufous Hummingbirds in many different locations, including Bristol, Blountville, Flag Pond, Elizabethton and Hampton. I have also observed Allen’s hummingbirds in Mountain City and Johnson City. I know of records of these small birds from Erwin, Roan Mountain, Johnson City and many other locations throughout the region. Winter hummingbirds are a delightful surprise for their hosts, but their presence no longer shock long-time birders.

Photo by Bryan Stevens • Rufous hummingbirds have been extensively documented as wintering throughout the southeastern United States. This male rufous hummingbird was documented in Hampton, Tennessee, a couple of years ago.

“Hosting a hummingbird in winter is a first for us, so we enjoy having him here,” Ellen wrote. “I feel that I am responsible to keep the little guy alive through the cold months.”

Doing so has meant staying atop some challenges.

“I monitor the feeder to make sure it doesn’t freeze,” Ellen wrote. “I have read the nectar doesn’t need to be replaced as often in winter, but I still change it every 2-3 days.”

She’s taking no chance with the health of her tiny visitor. “I think he needs to have fresh to stay in good health,” Ellen wrote. “I have two feeders, so when I remove one, I immediately replace it with another. That way his food source is not disrupted.”

Ellen noted that the hummingbird seems to be able to stand the cold nights. “I take in the feeder at night, and he looks for it just at dawn in the morning,” she wrote.

She contacted Bruce Peterjohn at the Patuxent Wildlife Research Center. Her visiting ruby-throated hummingbird is the first he has heard of in Virginia for the winter season this year, although Peterjohn informed Ellen that some ruby-throated hummingbirds usually overwinter close to the Chesapeake Bay in Virginia.

Peterjohn, the chief of the US Bird Banding Laboratory for USGS, is the person responsible for administering the national bird banding program and the data management system for bird banding and band encounter datasets. His personal banding activities are focused on banding hummingbirds in the mid-Atlantic region, especially hummingbirds that appear during late autumn and winter.

With the dawning of the new year, Ellen’s visiting hummingbird remained present. “I am happy to help this little bird get through the winter,” Ellen said.

I checked back with Ellen on Jan. 29 to see if the hummingbird remains in residence.

“He made it through the last storm with wind chills at zero or below,” she replied to my email. “Now we have more cold coming and I am hoping for the best.”

I imagine Ellen is a good host for many birds, not just the unseasonable hummingbird, that visit her yard and gardens.

In our correspondence, she shared some sightings of warblers, which is my favorite family of birds.

“By the way, I have not seen a hooded warbler,” Ellen wrote. “I see warblers pass through during spring, like Tennessee warblers and black-and-white warblers.”

I’m hopeful that she will spy a migrating hooded warbler, perhaps this spring. In the meantime, she’s hosting a wintering hummingbird. “I am happy to help this little bird get through the winter,” Ellen wrote.

HMSP plans Great Backyard Bird Count events

Hungry Mother State Park in Marion, Virginia, plans some bird walks on Saturday, Feb. 16, to coincide with the Great Backyard Bird Count.

The GBBC 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. 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.

Photo by Ted Schroeder/Great Backyard Bird Count • Evening grosbeaks may be more common on this year’s GBBC, according to early reports on the movements of these large, colorful finches.

Each checklist submitted during the GBBC helps researchers at the Cornell Lab of Ornithology and the National Audubon Society learn more about how birds are doing, and how to protect them and the environment we share. Last year, more than 160,000 participants submitted their bird observations online, creating the largest instantaneous snapshot of global bird populations ever recorded.

To help participants become better citizen scientists, some field guides and binoculars will be provided during the activities at Hungry Mother State Park. Supplies of these items, however, are limited.

The walk will commence at 8 a.m. Either Master Naturalist Randy Smith or Hungry Mother volunteer Mike Evans will conduct the walk. Participants are also welcome to bird solo or with a few friends to cover more territory.

At 9 a.m., participants will return to parking lot five for “Breakfast in a Bag” with the Holston Rivers Master Naturalists. While enjoying breakfast, attendees will be invited to wander over to the park’s restaurant to check out various hands-on birding activities.

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

Photo by Bryan Stevens • Although found during counts held in other seasons, no ruffed grouse was found on the 2018 Elizabethton Christmas Bird Count.

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.

Yellow-rumpWarbler (1)

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.
