Hummingbird numbers spike as summer season advances toward autumn

 

From the shade of my front porch, I watched about a half dozen ruby-throated hummingbirds cavort among the blooms of a large mimosa tree on a recent evening. The tree apparently holds an extraordinary attraction for the hummingbirds, as well as the pipevine swallowtail butterflies and other pollinating insects. I enjoyed watching the greenish hummingbirds zip among the profusion of pink mimosa blossoms, which have always reminded me of the thin fiber-optic filaments popular on some artificial Christmas trees and other decorations during the holidays. To draw so many different insects, as well as hummingbirds, the mimosa blooms must provide a rich source of nectar.

While I have almost wilted from the recent extended heat wave, the ruby-throated hummingbirds at my home appear to have downright thrived during these sunny, hot days of mid-summer. Once again, these tiny birds must have enjoyed a successful nesting season, based on the numbers of young hummers visiting both my feeders and flowers. The uptick in the presence of hummingbirds took place without much fanfare, but after a couple of months of “hummer doldrums,” it was impossible for any observer to miss the way these tiny birds have become much more prevalent in recent weeks.

Coinciding with this resurgence of the hummingbirds at my home, I received a post on Facebook from Philip Laws, a resident of Limestone Cove. Apparently, Philip, too, has noticed that hummingbird numbers are on the rise.

“Seemed like a slow hummingbird summer,” he wrote. “But two days ago the babies started hitting the feeders and everything looks much brighter!”

I also enjoyed a recent phone conversation with Erwin resident Don Dutton, who wanted to know why hummingbirds have been scarce around his home this summer. I’ve noticed fewer hummers at my own home this summer, but it’s natural for numbers to fluctuate from year to year. I anticipate that numbers will rise as hummingbirds begin migrating south again in the coming weeks. At that time, the adult hummers will be joined by the young birds from this season’s successful nesting attempts.
Don shared that when he lived out west, he often visited Mount Charleston near Las Vegas, Nevada, where he saw swarms of hummingbirds comprised of various different species. In the eastern United States, the only nesting species is the Ruby-throated Hummingbird.

For readers who have felt slighted by hummers so far this season, perhaps it’s time to try your luck again at attracting them. The surest method is to keep a sugar water feeder available to attract them on their way south later this summer and into the fall. A visit to a plant nursery can also provide an abundance of blooms to use to lure hummers to your gardens. Some late-blooming summer flowers attractive to hummingbirds include canna, cardinal flower, gladiola and crocosmia. While the widely held belief is that hummingbirds prefer red blooms, they will gladly visit any flower that rewards them with a sip of nectar.501-7006-blk

Late summer and early fall, even more so than spring, are usually the best times to enjoy hummingbirds, when they are usually at their most common. There are a couple of reasons for this annual increase. First, nesting female hummingbirds have reared their young, which then begin visiting feeders and gardens to compete with their elders at flower blossoms and sugar water feeders. Second, adult males and females that migrated farther north usually begin swinging southward again in late July and early August.

According to the website hummingbirds.net, mature male hummingbirds usually follow an earlier departure date than adult females and immature birds. The organizers of the website theorize that by leaving early in the fall, the adult male hummingbirds free up resources for their developing offspring. After all, it’s the least they can do since adult male hummingbirds play absolutely no role in helping females with the process of nesting and rearing young. All young hummingbirds are, in effect, raised by single mothers.

Despite their tiny size, hummingbirds are tough birds. One species, the rufous hummingbird, ranges as far north as Alaska. Several tropical species have adapted to the frigid conditions that occur at the higher elevations of the Andes Mountains.

As I have done in years past, I advise a patient but proactive approach for attracting hummingbirds. Keep feeders readily available. If possible, offer flowers, too. Don’t keep your landscape too tidy. A perfectly manicured lawn is like a desert for hummingbirds. Provide some shrubs and trees to provide cover and perching branches. Water features, particularly waterfalls and fountains, are also a reliable means of attracting hummingbirds, as well as other birds.

If you have felt slighted by hummers so far this year, keep a sugar water feeder available to attract them on their way south later this summer and into the fall. To share a sighting, make a comment, or ask a question, send email to ahoodedwarbler@aol.com.

Keep a look out for wandering waders during late summer season

Summer heat and humidity make the summer season my least favorite one for birding, but every season brings birding surprises. I was reminded of this fact when Larry and Amelia Tipton sent me a recent email asking for help with the identification of some birds near their home.

Attaching a photo with their email, the Tiptons wrote, “These birds showed up a few days ago and we cannot identify them. We would like to know what they are.”

When I opened the photo, I realized that the birds captured in the image would not be considered out of place if the Tiptons lived near the coast of the Carolinas, Georgia or Florida. The birds in the photo, however, were somewhat unexpected in the foothills of western North Carolina near their home in the town of Old Fort.

WhiteIbises

“We live on a farm near the Catawba River but have mostly woodland and fields,” the couple added. “We do not have a pond on our property but have a branch and a larger creek nearby.”

I wrote back and told the Tiptons that the birds they photographed were young white ibises. I informed the Tiptons that the two young ibises are likely testing their wings, so to speak, after leaving the care of their parents. If they like the area, and it sounds like they do, they may decide that the branch and creek are just what they need.

I received a followup email. “We sort of knew these were water birds but were surprised to find them so far away from marsh or wetlands or the ocean,” the Tiptons wrote. “We thought maybe a storm blew them off course during flight.”

While a diverting storm can’t be ruled out, it’s normal behavior for young wading birds to disperse far and wide after leaving the nest. North American waders, or wading birds, include such long-legged species as herons, egrets, bitterns, ibises, storks and spoonbills. Most species are associated with wetlands or coastal areas.

Late summer birding is usually a period of doldrums as heat and humidity can discourage birders as well as diminish bird activity. However, it’s also the time of year when birders can make some unexpected surprises as wandering waders, such as the ibises discovered by the Tiptons, explore uncharted territory.

Other waders this season showing up in unexpected location have included a wood stork found by Linda Walker in Polk County, Tennessee. Likes the ibises in North Carolina, the stork was confining its activities to a small branch bordered by heavy vegetation. These branches are a far cry from the usual wetland haunts of these two species.

Overall, the white ibis and wood stork have some superficial similarities. They are both long-legged white birds with black wing tips and unusual down-turned bills that they use to probe for food, which largely consists of fish and other aquatic prey.

The latter is North America’s only native stork. According to the National Audubon Society, Florida once provided a stronghold for the wood stork in the United States. Unfortunately, the population crashed in the 1990s, decreasing from around 150,000 birds to fewer than 10,000. In recent years, numbers have increased and wood storks have expanded their breeding range into South Carolina. Wood storks are nearly four feet tall, making them one of the tallest of the waders. Wood storks have a dark, featherless heads, giving them a resemblance to vultures. For the most part, they’re rather grotesque birds when observed at close quarters. Soaring overhead on thermal updrafts, wood storks look quite graceful and even majestic thanks to their white plumage and black accents. A wingspan of 65 inches gives them the means to soar easily.

Storks-Two

Worldwide there are 19 species of storks, but the wood stork (pictured) is the only native stork   found in the United States.

The Audubon Society identifies the white ibis as one of the most numerous wading birds in Florida, but the bird is common also in other parts of the southeast with appropriate wetland habitat. Like the wood stork, the ibis has declined in Florida in recent decades largely as a result of human encroachment. The white ibis looks like a bird that could have been invented by Dr. Seuss. The all-white plumage is contrasted by pinkish-orange legs, a reddish-pink bill and bright blue eyes. In flight, the white ibis shows black feathers on the edges of its wings.

The affinity for water and wetlands relates to the diet of most waders, which consists of fish and other aquatic prey such as amphibians, crustaceans and even insects. For the remainder of July and into August and September, birders should monitor ponds, small lakes, rivers and even branches and creeks for any wandering waders. For instance, I once made a trip to a park in Greeneville, Tennessee, to observe a pink-hued roseate spoonbill that had made a rare stopover in the region. While that observation took place nearly 20 years ago, I remember vividly finding the pale pink bird playing odd man out among a flock of several dozen Canada geese as a soft rain drizzled from an overcast sky. Although many of the waders cling to coastal habitats, they have wings like other birds and know how to use them. Other waders have been known to show up in unlikely locations, including birds such as tri-colored heron, limpkin and snowy egret.

Of course, I hope to hear from any readers lucky enough to glimpse one of these unanticipated finds. Enjoy your birding.

Skittish nature means getting to know towhees takes some effort

Mary Beierle, who lives in Elizabethton, Tennessee, sent me an email to share information about recent nesting activity by a pair of Eastern towhees at her home in the Stoney Creek community.

“Just wanted to tell you that we have a nesting pair of Eastern towhees here in Stoney Creek,” Mary wrote in her email. “This is the first year they have stayed after a brief visit in early spring.”

While not as many people may be familiar with Eastern towhees as, say, northern cardinals or ruby-throated hummingbirds, those who have made an acquaintance with these unusual songbirds are, like Mary, captivated instantly.

“I am very fond of these birds,” she noted in her email. “The male is really beautiful and the female is also lovely, although not as colorful as the male.”9780307370020-us 2

Eastern towhees spend much of their time on the ground and hidden in thickets and hedges. As a result, other common names for this bird includes “ground robin” and “swamp robin,” which refer to some of this bird’s habitat preferences. They’re not thrushes, however, and are unrelated to thrush family members such as American robin, Eastern bluebird and wood thrush. Instead, towhees are one of the larger members of the sparrow family.

Mary noted some of this bird’s typical behavior from her observations. “I love the way they hop around,” she wrote. “They are very skittish, and I can’t get them to stand still for a photo.”

At my own home, I have a pair of Eastern towhees currently occupied with nesting. When I get too close, both parents claim an elevated perch and call in agitation as long as I am in the vicinity. The towhees are just one of many nesting birds so far this spring. Other nesting birds in my yard or the surrounding woodlands this spring have included tree swallow, Eastern bluebird, brown thrasher, song sparrow, American robin and Eastern phoebe.

The Eastern towhee represents a bit of a milestone in my personal birding history. I saw and identified my first Eastern towhee in early spring in 1993. At that time, I was struggling to identify some of the common visitors at my feeders. I was acquainted with white-breasted nuthatches, blue jays, downy woodpeckers, Carolina wrens, dark-eyed juncos and a handful of other birds. When I looked out a window and saw this bird feeding on the ground, the morning sun illuminating his dramatic plumage of black, white and rufous red, I was immediately aware this visitor represented something new and unexpected.

Consulting a field guide — I was using the Golden Nature Guide to the Most Familiar American Birds at the time — I soon found a painted illustration of a rufous-sided towhee that matched in every detail the bird I had just observed on the ground beneath a blue spruce in my yard.

Many of the older field guides still list the Eastern towhee as “rufous-sided towhee” which is actually more descriptive of the bird’s appearance than the word “eastern.” In 1995, ornithologists renamed the rufous-sided towhee to Eastern towhee and also separated the Eastern species from its western counterpart, the spotted towhee. Until that point, these two towhees had been considered different races of the same species. In 2003, I saw a spotted towhee during a visit to Salt Lake City, Utah. The bird looks almost identical to an Eastern towhee except for considerable white spotting — hence its common name — on the bird’s back.

Male Eastern Towhee sings from a perch.

Male and female Eastern towhees each possess a stately if subtle beauty. Males have a black hood. The black coloration extends into the back and tail. The belly is white and the sides are flanked with a rusty-red color. In flight, their black tails are bordered with white feathers, which produces a dramatic flash of contrasting colors. The female Eastern towhee is an attractive bird in her own right. She shares the rufous sides and white coloration that are present in the male’s plumage. However, the male’s black feathers are replaced by a warm, chocolate brown plumage in the female. In addition, their bright red eyes help set these birds apart from other songbirds.

The Eastern towhee is one of my favorite yard birds, but not just because of its dramatic appearance. These birds also have some instantly recognizable vocalizations. With the arrival of spring, the males will seek elevated perches for extensive singing bouts to attract mates and establish territories. Their song has been interpreted, quite accurately, as an emphatically delivered “Drink your tea!” They also have some alarm notes, such as “Chew-ink” and “Toe-Hee,” which provides the basis for this bird’s common name.

Eastern_Towhee

Female Eastern Towhees are usually more retiring than males.

They are often found in the same sort of tangled habitat favored by Northern cardinals, gray catbirds and brown thrashers. To attract these birds, simply refrain from doing too much to alter your landscape. For instance, don’t manicure every square inch of your yard. Leave some wild corners that will run rampant and provide a luxurious tangle for birds that thrive under cover. In the southern United States, towhees prosper in scrub palmetto habitats. In our region, any hedge or bramble thicket will provide adequate cover to make these birds feel welcome.

While they may never completely lose their wariness, towhees will become gradually more accepting of sharing a yard with people. It helps that they will readily visit feeders for sunflower seeds. If you succeed in attracting a family of Eastern towhees to your yard and garden, I am confident you’ll not be disappointed.

Fruit increases chances of visit from scarlet tanagers

 

Last summer, Annette Bryant emailed me some beautiful photos she had taken of birds at her home in Marion, North Carolina.

“Photographing birds has been a passion of mine for many years,” Annette wrote to me. “I look forward to our blueberries getting ripe because I see certain birds only at that time.”

ScarletTanager-Bryant

One of those birds, she noted, is the scarlet tanager. Anyone who has beheld a scarlet tanager is hardly likely to forget the observation. Thanks to a recent observation I made of one of these birds, I have been reminded of some of the breathtaking birds — including the scarlet tanager — that make the mountains of northeast Tennessee, western North Carolina and southwest Virginia their summer home. The extraordinary appearance of the male scarlet tanager is certainly one that sets it apart from most other songbirds.

This tanager is not typically a feeder visitor, but bird enthusiasts can lure these birds with fruit, such as orange slices placed in special feeders or simply spiked onto the branches of backyard trees. As an added bonus, orange slices can also attract birds such as brown thrashers, Baltimore orioles and gray catbirds. The scarlet tanager indulges its fondness for fruit by incorporating various berries into its diet. In addition to the blueberries mentioned by Annette, other fruit-bearing trees and shrubs — mulberry, elderberry, serviceberry and wild cherry — will make your yard or garden more inviting to this somewhat elusive bird.

I usually have a few scarlet tanagers in residence around my home during the summer months, but I haven’t seen one so far this spring. However, my luck changed while taking part in the Summer Bird Count for Carter County, Tennessee. The count, conducted by members and friends of the Elizabethton Bird Club, has been a long-running survey of summer birds in the region. Along with fellow birders Jean and Brookie Potter, Chris Soto and Mary-Anna Wheat, I got a timely reminder of the beauty of the scarlet tanager while we searched for birds on Holston Mountain near Elizabethton, Tennessee. A stunning male tanager showed up and entertained us with fantastic looks for several moments.

The male scarlet tanager boasts a brilliant plumage of crimson red paired with black wings and tail. Of course, like many other birds, the female scarlet tanager makes no real claim to the common name with her comparatively drab greenish plumage. However, the scientific name, Piranga olivacea, gives a nod to the olive-green plumage of females, young males and even adult males when they’re molting their feathers.

So, why is it so difficult to lay eyes on such a brightly colored bird? The answer rests with this bird’s daily routine, which is usually conducted among the upper woodland canopy in such tall trees as oaks and poplars.

Scarlet-Tanager

Fortunately, male tanagers produce a distinctive song. Upon first hearing it, listeners might mistake the hidden singer for an American robin. Listen a little closer, however, and the song sounds as if it is being delivered by a hoarse robin with a sore throat. The male tanager also makes a vocalization described as “chip-burr” that is easily heard.

If we were to see a scarlet tanager in a rain forest in South America, we might not be so surprised by its vibrant plumage, usually associated with many tropical birds. The scarlet tanager is certainly better attired than most birds to provide observers a glimpse of a creature that would indeed look more at home in the jungle.

Worldwide, there have traditionally been about 240 species of tanagers. Experts have changed some of the ways they classify tanagers, so that figure is no longer set in stone. Tanagers are a New World family of birds, concentrated mainly in the tropics of Central and South America. Some of the world’s other tanagers are known by extremely descriptive names, including yellow-backed tanager, blue-and-yellow tanager, seven-coloured tanager, gilt-edged tanager, green-capped tanager, beryl-spangled tanager, opal-rumped tanager and blue-gray tanager.

Osprey’s fishy diet sets it apart from most other raptors

Jim and Tammie Kroll emailed me about a very interesting bird observation on the Virginia Creeper Trail last month.

They saw a bald eagle along the Virginia Creeper Trail on May 14. “It was between Alvarado and Damascus,” Jim wrote in the email. We got to see it at two different locations and watched it around 15 minutes at each location.”

DSCN3266

Photo by Jim and Tammie Kroll • This adult bald eagle was seen along the Virginia Creeper Trail.

He added that they talked to a woman who informed them that she also sees an eagle in the same area on the Creeper Trail.

The Krolls also shared a photo of the eagle. I’m always glad that to hear that observing the nation’s official bird is no longer a rare occurrence in the region. While I haven’t seen any bald eagles this year, I have observed a raptor that share many characteristics with them.

Ospreys, also known by the common name of “fish hawk,” occur worldwide. Ospreys migrate through the region in spring and fall, making sightings more likely along some lakes and larger rivers. I see them even more often when I travel to South Carolina, where these medium-sized raptors are common along the coast and in wetlands.

Some recently published books provide insight into the lives of bald eagles and ospreys. Teena Ruark Gorrow and Craig A. Koppie are the authors of the recent book, The DC Eagle Cam Project: Mr President and First Lady. This book profiles a celebrity pair of eagles that have nested for the past few years in U.S. National Arboretum in Washington, D.C.

osprey-book-Cover

Front cover of a book by Teena Ruark Gorrow and Craig A. Koppie featuring photos of a nesting season in the life of a family of ospreys.

Gorrow and Koppie have also written other books together, including one offering a pictorial journey through an osprey nesting season. Titled “Inside an Osprey’s Nest,” this book provides an account of two fostered osprey chicks that receive new parents in a heartwarming, real-life account of a family of ospreys associated with the Chesapeake Conservancy Osprey Nest Cam.

During a recent interview, Gorrow shared that bald eagles and ospreys share more than a few things in common.

“The bald eagle, Haliaeetus leucocephalus, is America’s national bird and symbol,” Gorrow said. “It is a large raptor, or bird of prey, found only in North America. Also a raptor, the osprey, Pandion Haliaetus, is a large hawk found on every continent across the globe except Antarctica.”

Like the American bald eagle, Gorrow noted that ospreys experienced devastating health effects and reproductive failures from widespread human use of dangerous pesticides like DDT.

“By the 1970s, population numbers had plummeted to catastrophic levels for both eagles and ospreys,” she said. “Federal actions were put into place which imposed migratory bird protection and banned DDT. These measures, along with the work of dedicated scientists, conservationists and citizens, have helped these magnificent raptors recover.”

Gorrow said that when selecting a nest site, bald eagles and ospreys identify an area near water with a plentiful food supply and nearby trees. “With diets consisting mostly of fish, both require foraging areas rich in fishery resources,” she said.
During nesting season, ospreys and eagles are seen as competitors, even though food is abundant in the Chesapeake Bay region. “Bald eagles are opportunists and will usually pirate fish prey from osprey when given the chance,” Gorrow said.

Nesting season for eagles begins earlier than ospreys, so they have the upper hand in defending territories. “Eagle pairs in the Chesapeake Bay area usually lay eggs in mid-February, while the ospreys return from their southern wintering destinations around mid-March,” Gorrow said. “Ospreys generally build nests in March or April and lay eggs soon after.”

Early naturalist and artist John James Audubon painted this work of art featuring an osprey with a fish held in its talons.

The two large raptors also demonstrate other distinct preferences.

“Bald eagles utilize living and dead (known as snags) trees as nest sites,” she said. “Eagles rarely tolerate humans near their nests.

“On the other hand, ospreys are relatively tolerant of humans and sometimes build nests on private pavilions or docks beside waterfront properties,” Gorrow continued. “They seem to favor artificial structures and often construct over-water nests on the steel supports of bridges, channel markers, navigational buoys, fishing piers, jetties, and manmade nesting platforms. Ospreys sometimes choose snags with an open treetop or claim tall, artificial structures resembling dead trees, such as towers, utility poles, television antennas, road signs and stadium lights. They also sometimes nest on chimneys and rooftops on uninhabited buildings.”

A more in-depth glance into the lives of ospreys is available in the book “Inside an Osprey’s Nest,” which retails for $24.99. When purchased through the Chesapeake Conservancy at http://www.chesapeakeconservancy.org, $10 from every purchase supports conservation programs along the Chesapeake Bay Watershed. The book is also available at http://www.schifferbooks.com, Amazon.com and other booksellers.

Readers report on robin, purple martin that stand out from other members of their flocks

 

Albino-Swallow

Birds of a feather, as the old saying goes, tend to flock together, but what happens when a member of the flock stands out from the rest? Although conventional wisdom mandates that being conspicuous is not helpful for most wild creatures, some of them can’t help but get attention. Different readers have brought to my attention some birds at their homes that instantly stood out.

Sara and Ed Gschwind, residents of Bristol, Tennessee, have been keeping tabs on an American robin in their yard that is showing an extensive amount of white feathers in its plumage. For the most part, this particular robin has a white head, largely white wings and extensive white in the typically red breast. “My 88-year-old mother, Nora Rockett, suggested I send a photo to you,” Sara wrote in an email.

Robin-PartialAlbino

Photo by Ed Gschwind • A leucistic American robin enjoy time in a bird bath. Albino and leucistic birds are rather rare in nature.

Sara said that her mother, who has lived in Bristol all her life, has never seen anything like it. I replied to Sara’s email, asking for a few more details.

While the robin interacts with others of its kind, the Gschwinds haven’t seen any evidence this particular robin is attempting to nest. Ed took a photograph of the robin enjoying the water in a bird bath in the Gschwind yard.

“The robin bathes every day, and loves the water like all robins do,” Sara wrote. “The robin has been here since the robins returned three months ago. I’m trying to keep it happy.” Since the robin is a regular visitor, I agree that they’re doing a good job keeping the bird happy, since it’s not shown any inclination to leave their yard.

Tom Brake, who lives in Abingdon, Virginia, contacted me through Facebook about a male purple martin with extensive white feathers residing at the purple martin colony he has established at his home.

Purple martins are the largest member of the swallow family in the United States. Like many other swallow species, they nest in colonies. Martins are cavity-nesting birds that readily accept hollow gourds or special purple martin condominiums for nesting.

“Currently I have nests in 43 compartments with 20 being active (eggs having been laid),” Tom wrote. “Last year I had 51 pairs, and I hope to get close to being back to 60 or 70 active pairs this year. The next two weeks will be the busy time for completion of nests and laying.”

PurpleMartin-Albino-TomBrake

Photo by Tom Brake • A leucistic male purple martin perches with its mate, a typical female purple martin, near a hollow gourd they may use for nesting purposes.

As for the bird showing the white feathers, Tom has named him “Leuie” because the bird is an example of leucism, a condition related to albinism.

Albinism is a genetic, or inherited, condition resulting in a complete lack of production of pigmentation. Albino birds are, for the most part, extremely uncommon. I’ve heard of a variety of birds, ranging from hummingbirds and American robins to various ducks and swallows, that have a tendency to produce albino individuals.

Leucism is another genetic mutation that causes affected birds to grow feathers that are pale or whitish overall. A faint pattern may be visible. Leucism is also uncommon, but is more common that albinism. Both the robin in the Gschwind yard and the purple martin at Tom’s home are examples of leucistic birds.

Tom noted that “Leuie” is doing well so far. “He has a mate, but their first clutch of four eggs was either thrown out by a second year male martin or discarded by themselves because they sensed non-viability,” Tom wrote in a Facebook message. “Maybe the cold, wet weather had something to do with the loss.” He noted that the same thing happened recently to two other nests.

“Leuie and mate are still using their gourd, so I expect they will re-clutch,” Tom wrote. The term “re-clutch” means that Leuie’s mate will lay a new batch of eggs and Leuie will be ready to carry out his own paternal duties to help raise any resulting young.

Albinism and leucism are not the only conditions that can affect pigment in a bird’s feathers. Some birds have the opposite problem in that they produce too much pigment, resulting in a much darker bird than what would be typical. The plumage of such affected birds is described as melanistic, which is in stark contrast to an albino bird. With a melanistic bird, the feathers are much darker than usual because of an abundance of pigment. In rare albino birds, the opposite occurs and the lack of pigment in the feathers leave them looking white. Completely albino birds also tend to have red eyes. It’s probably better for a bird to be melanistic. Albino birds tend to stick out like sore thumbs, attracting the attention of predators.

Robins-AlbinoAndRegular

Photo by Ed Gschwind • Compare the leucistic American robin in the bird bath with the typical robin perched in a nearby chair. Albino birds are rather rare in nature.

I’ve only seen a few albino or partial albino birds in person, although I have observed videos and photographs of such birds. During a trip to Salt Lake City, Utah, in 2006, I observed an albino Brewer’s blackbird. An albino blackbird is almost an oxymoron. This particular blackbird had a white upper body and head and a black lower body. At first, I thought it might be a small tern, but closer observation — and identification of the birds with which it was associating — eventually confirmed that it was a Brewer’s blackbird, a common species in Salt Lake City.

Those observations remain my best looks at albino birds in the wild. I’ve also seen partial albinos, including an American Crow with white feathers in its wings that inhabited the woodlands and fields at my home for several years. I’ve also observed a couple of American goldfinches over the years that would probably qualify as leucistic birds.

A few years ago, I saw an albino Red-tailed hawk while driving between Erwin, Tennessee, and Asheville, North Carolina, on Interstate 26. The hawk was often present near the North Carolina Visitors Center. I’ve also heard from readers over the years about birds such as American goldfinches and downy woodpeckers exhibiting albino tendencies.

Albino-Hawk

These issues involving the absence or abundance of pigment can complicate bird identification. After all, all-white birds, from snowy owls and tundra swans to great egrets and snow geese, do exist in nature. Even in these birds, however, there’s usually some other color present to break up the uniformity of the bird’s plumage. Keep in mind that such rarities as albino individuals of such common species as house finches and American robins can show up at your feeders or in your yard. It’s just another way birds constantly surprise us.

Spring Bird Count participants deal with unseasonal cold snap

The 74th annual Elizabethton Spring Bird Count was held on Saturday, May 6. A total of 43 observers in nine parties took part in the annual survey, which consists Carter County and parts of adjacent Johnson, Sullivan, Unicoi and Washington counties. In addition to Elizabethton, the count includes territory in such cities as Elizabethton, Erwin, Kingsport, Bristol and Johnson City.

Count-Gobbler

Photo by Bryan Stevens • A male gobbler seeks the attention of hens, as all these Wild Turkeys add to the number of this species found during the count.

The most unusual aspect of this year’s count involved rather cold conditions, according to long-time count compiler Rick Knight. Although held nearly a week into May, this was one of the coldest days ever experienced on a spring count. The temperature range was 36 to 54 degrees. Light rain fell before sunrise; the morning was partly cloudy to cloudy, then the afternoon saw light rain, with light snow showers at the higher elevations and a half-inch accumulation of snow on Roan Mountain.

Knight noted that previous cold spring counts included: 32 to 55 degrees in 1979, 44 to 52 degrees in 1987, and 27 to 54 degrees in 1992. Despite the weather, participants managed to find 148 species, which is exactly the average over the last 30 years, but below the average over the last decade, which stands at 154 species.

The most common species on this year’s Spring Bird Count was the Cliff Swallow with 1,046 individuals — a new record for this species — found this year. Other common species include European Starling (704), American Robin (693) and Tree Swallow (526).

A Stilt Sandpiper found in Washington County represented only the third time this species has been observed during the Elizabethton Spring Bird Count. As always, Knight said there were a few notable misses, such as Northern Bobwhite, Ruffed Grouse, Pied-billed Grebe, Brown Creeper, Winter Wren, Swamp Sparrow and Pine Siskin. In addition, no gulls were found on any of the area lakes.

Count-MaleMartin
