Birding is a popular pastime for many Americans.

Reader’s mystery bird turns out to be Louisiana waterthrush

On occasion, readers seek out my help with identifying birds they encounter. I am always glad to assist. Photographs, a recording of the bird’s song, or even a well-written description are often all that’s necessary to pinpoint the identities of mystery birds.

Lewis and Jeana Chapman, residents of Laurel Bloomery, Tennessee, notified me in an email that they have been enjoying some good birdwatching trips. They also wanted some help with the identity of a bird they observed last summer.

“My wife and I love to go to the Creeper Trail in Virginia and enjoy the creek,” Lewis wrote in an email. “On these trips in the summer months, we have watched this bird run along the rocks of the shore feeding.”

He also mentioned that he had attached in his email some photos, which proved extremely helpful. “Our closest guess at what type of bird it is was a spotted sandpiper, but its beak/bill seems too short. Any help you can give us would be greatly appreciated.”

A quick scan of the photos the Chapmans sent with their email helped me narrow the options down to two related birds — a Louisiana waterthrush and a Northern waterthrush. I used three criteria — location, season and plumage — to identify the bird in their photos as a Louisiana waterthrush.

Louisiana Waterthrush

Photo by Adobe Stock • Subtle plumage differences, as well as habitat, behavior and seasonal presence, are factors in distinguishing the Louisiana waterthrush, pictured, from the closely related Northern waterthrush. The Louisiana waterthrush nests along fast-moving streams in the area while the Northern waterthrush does not breed in the region.

 

The Chapmans had good reason to suspect the bird might have been a spotted sandpiper, but for the true identity of the bird in question, it’s necessary to delve into the family of warblers, which includes species such as American redstart, ovenbird, common yellowthroat, Northern parula and black-throated blue warbler.

The two waterthrushes are very similar in appearance. Louisiana Waterthrushes has a heavier bill and a white eye line, while the Northern Waterthrush’s eye line is usually somewhat yellowish-beige. A Louisiana waterthrush typically also has a whiter belly and underparts.

Appearance wasn’t even the most important element of the criteria. Location and season more readily helped confirm the identity. The Louisiana waterthrush has a range concentrated on the southern part of the eastern half of the United States, mostly south of the states of New York, Michigan and Wisconsin. In this region, only the Louisiana waterthrush is known to nest. The Northern waterthrush is strictly a spring and fall migrant, electing to nest near bogs and slow streams in Canada and the northern tier of states in the United States.

The Louisiana waterthrush also attracts attention with its characteristic “teetering” gait. Much like the spotted sandpiper, this waterthrush bobs the rear half of its body up and down as it walks and forages by the sides of streams. In their behavior, this shorebird and this warbler are very much alike. The waterthrush will often turn over wet leaves or other stream debris to search for prey items, such as aquatic insect larvae, crustaceans, snails and even small fish. The Louisiana waterthrush was once known as the water wagtail, which makes reference to the aforementioned teetering gait.

Many warblers have shown signs of decline in recent years. The Louisiana waterthrush, however, appears to have bucked that trend. According to the website All About Birds, Louisiana waterthrush populations were stable between 1966 and 2015, based on statistics from the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 360,000, with almost all of those individuals spending at least part of the year in the United States. About a quarter of the population retreats into Mexico during the winter season. The rest winter in Florida and some of the Gulf Coast states, as well as the islands of the Caribbean.

While most songbirds are fortunate to survive two or three years in the wild, at least one Louisiana waterthrush lived to the age of at least 11 years and 11 months. The bird, a male, was seen in New Jersey in the wild and identified by a band on one of his legs. He had been banded in the same state, according to All About Birds.

The two waterthrushes are the only species in the genus Parkesia, so named to honor American ornithologist Kenneth C. Parkes, who was for many years Curator of Birds at Carnegie Museum of Natural History. The common name of the Louisiana waterthrush is not a very apt one, as this bird does not have any special affinity for the state of Louisiana. Someone collected some of the early specimens of the Louisiana waterthrush in its namesake location, and the name has stuck through the years.

Not every bird mystery that comes my way via Facebook or in an email is so easily resolved. This identification, which happened to involve the New World warblers, my favorite family of birds, once again showed me the amazing diversity of this group of birds. From the terrestrial Louisiana waterthrush to the treetop-dwelling cerulean warbler, it’s an amazing group of songbirds I’m always happy to introduce to bird enthusiasts.

No cowbird ever knows its biological parents

While many birds are excellent parents, others lack any maternal or paternal instincts altogether. The common cuckoo, a nesting bird in Europe and Asia, is a well-known brood parasite that would rather slip its eggs into the nest of other bird than raise its own young. In scientific terms, “brood parasite” refers to creatures that rely on others to raise their young. In addition to some birds, this tactic is also employed by some species of insects and fish.

COWBIRD-Female

Photo by Bryan Stevens • Female brown-headed cowbirds stay alert to observe bird leaving or coming to a nest. Once they have located a nest, these birds slip their own eggs into the nests of other birds.

The strategy is effective, if, in the human way of thinking, rather heartless. In biological terms, however, this “foster parenting” allows brood parasites to ensure a new generation without expending much energy on the part of the actual parents. Some recent contacts with readers have reminded me that not all of our feathered friends would qualify for “parent of the year.”

Mike Dickenson of Bristol, Tennessee, contacted me on Facebook about a discovery he made in a nest built under the steps of his house.

Cowbird-Female

“I noticed two blue eggs,” he said. “I checked a few days later and noticed two gray eggs also. Did another bird sneak her eggs into the nest?” Mike also informed me that some of the eggs hatched shortly after he discovered them.

James Rowland of Erwin, Tennessee, sent me a message on Facebook asking me to identify a bird in a photograph he had taken. “What is this bird?” James asked. “It’s larger than a sparrow.”

He added that he observed and photographed the bird near the Covered Bridge in Elizabethton, Tennessee. A study of the bird in the photo revealed a very nondescript bird in largely gray plumage. Few of our birds are this plain and gray with almost no standout characteristics.

Photo by James Rowland • A brown-headed cowbird, probably a young bird or a female, near the Covered Bridge in Elizabethton, Tennessee.

In both cases, one of North America’s most successful brood parasites was involved. I responded to Mike and told him that is was entirely possible that a female brown-headed cowbird slipped some eggs into the nest beneath his steps. I likewise informed James that the bird in his photo looked like a brown-headed cowbird. I added that the bird was either a female or a young bird, since a male would have the brown head that gives the species its common name.

In North America, one of the best-known feathered brood parasites is the brown-headed cowbird. While many brood parasites are specialists, with females slipping their eggs into the nest of a specific species of host bird, the brown-headed cowbird approaches brood parasitism in a less discriminating manner. Female cowbirds have been known to lay their eggs in the nests of at least 221 different species of birds. No baby brown-headed cowbird ever knows its biological parents.

How did the brown-headed cowbird turn to a life of foisting eggs onto unsuspecting foster parents? The answer is connected with the American bison, also known as buffalo. When the bison roamed the Great Plains of the United States by the millions, flocks of brown-headed cowbirds followed the great herds, feeding on the insects flushed by the hooves of millions of bison. As the herds stayed on the move constantly, the cowbirds also developed a nomadic lifestyle. After the bison herd diminished, the cowbirds survived a potential crisis by simply transferring their bovine affinity from bison to domesticated cattle.

At times, this random and undiscriminating approach to reproduction fails. Some finches feed their young a diet that consists of a great deal of vegetable matter. Young cowbirds fed this protein deficient diet fail to thrive and ultimately perish.

Other birds blissfully bring a rich assortment of protein snacks — insects, spiders and other small invertebrates — that permits the young foster bird to thrive, at times at the expense of the host bird’s own young. About 20 years ago I observed a willow flycatcher bringing food to a young brown-headed cowbird at least twice the size of the “parent” trying to feed it. I’ve also seen song sparrows, dwarfed by a cowbird changeling, trying to keep their enormous baby bird well fed.

Cowbirds are members of the blackbird family, which includes such relations as orioles, meadowlarks and grackles. All cowbirds are confined to the New World and include species such as the screaming cowbird of Argentina, Bolivia and Brazil, as well as the bronzed cowbird of Central America and the southern United States, especially the states of California, Arizona, New Mexico, Texas, and Louisiana. Other cowbird family members include giant cowbird and the shiny cowbird.

Majesty of bald eagle suitable for America’s official bird

american bald eagle

Here’s an early “Happy Fourth of July” to all my American readers. I thought this week’s post should focus some attention on our national bird, the American bald eagle, which officially became the national emblem in 1782 when the great seal of the United States was adopted.

Despite elevating this native bird to such lofty status, we have not always been kind to the bald eagle. We allowed habitat destruction and toxic pesticides to bring this eagle to the brink of extinction. With some protection, however, the bald eagle rebounded. In fact, the Department of Interior took the eagle off the endangered species list on June 28, 2007.

The bald eagle has been more frequently observed by birders in Northeast Tennessee in recent years. Some of the area lakes in the region are good places to look for Bald Eagles, particularly in the fall and winter. A few lakes even host nesting bald eagles. For instance, this eagle has been documented nesting at Holston Lake in recent years.

I’ve observed bald eagles in Tennessee, South Carolina, Florida and Virginia. My most unusual observation of a wild bald eagle took place on Labor Day many years ago when an adult eagle flew over my grandparents’ home in Limestone Cove in Unicoi County. North America’s other eagle, the golden eagle, is a very rare visitor to northeast Tennessee. The golden eagle is primarily a bird of the western United States while the bald eagle ranges widely across the United States as well as into Canada and Mexico.
The eagles are incredibly majestic birds and important symbols of the value of natural places and creatures.

The bald eagle (Haliaeetus leucocephalus) is a member of a genus known as Haliaeetus, or sea eagles. There are seven other living species in the genus: the white-bellied sea eagle, Sanford’s sea eagle, African fish eagle, Madagascar fish eagle, Pallas’s fish eagle, white-tailed eagle and Steller’s sea eagle.

The bald eagle, however, is not considered closely related to eagles in the genus Aquila, or “true eagles,” in which the golden eagle is included.

Both male and female adult bald eagles have a blackish-brown back and breast; a white head, neck and tail; and yellow feet and bill. Juvenile bald eagles are a mixture of brown and white and reach full maturity in four to five years.

The female bald eagle is 35 to 37 inches in length, slightly larger than the male, with a wingspan that ranges from 72 to 90 inches. Bald eagles weigh from 10 to 14 pounds.

Despite these impressive characteristics, the bald eagle is dwarfed in comparison to one of its now-extinct relatives. The largest eagle ever to evolve was Haast’s eagle, which once thrived in New Zealand. This eagle was named for the German geologist Julius von Haast, who founded Canterbury Museum at Christchurch in New Zealand. Haast, who died in 1887, was one of the first scientists to study large flightless birds such as the moa family that once roamed New Zealand.

Julius_von_Haast 2

Julius von Haast

In fact, Haast’s eagle was considered a major predator on the population of New Zealand moas, some of which reached a height of 12 feet tall and a weight of more than 500 pounds. By contrast, female Haast eagles probably reached a weight of 22 to 33 pounds. Males, as is the case with most living eagles, are smaller than females and probably weighed between 20 to 26 pounds. This mega-sized eagle possessed a relatively short wingspan of roughly 8 to 10 feet wide. This wingspan compares to that recorded for large specimens of golden eagle and Steller’s sea eagle. Even the largest of today’s eagles, however, are about 40 percent smaller in body size than the size of Haast’s eagles. Despite their superior size, moas simply lacked any defense against the huge razor-like talons and sharp bill of the Haast’s Eagle.

Here are a few other eagle facts:

— Eagle bones are light because they are hollow. The beak, talons and feathers are made of keratin.
— The Madagascar fish eagle is the most rare eagle on earth, and one of the most rare birds. The current population is estimated at less than 400 individual birds, with perhaps around 120 breeding pairs.
— Bald eagles have 7,000 feathers.
— Wild bald eagles are long-lived birds and may live as long as 30 years. In captivity, however, the oldest documented Bald Eagle lived to be 47 years old.
— Bald eagles can lift as much as four pounds. They feed mainly on fish, but they will take advantage of carrion and scavenge for their meals. They will occasionally also take waterfowl as prey.
— The hunting area of bald eagles varies from 1,700 to 10,000 acres. Home ranges are smaller where food is present in great quantity.
— Bald eagles can fly to an altitude of 10,000 feet. During level flight, they can achieve speeds of about 30 to 35 miles per hour.
— All eagles are renowned for their excellent eyesight.
— Once paired, bald eagles remain together until one dies. Bald eagles lay from one to three eggs. The 35 days of incubation duties are shared by both male and female.
— Today, there are about 10,000 breeding pairs of bald eagles.

Brown pelicans now thrive along nation’s coasts

Pelican=Reflected

Photo by Bryan Stevens • A young brown pelican fishes along the causeway at Huntington Beach State Park in South Carolina. These pelicans usually dive into the water, capturing prey in a large pouch that is connected to their bill. Pelicans also snatch fish while floating on the surface.

Back in early March I enjoyed a trip to coastal South Carolina, visiting locations near Pawleys Island such as Huntington Beach State Park, Myrtle Beach State Park and Brookgreen Gardens.

During my six-day stay in the South Carolina Low Country, I observed 95 species of birds, including several that should be making their spring return to our region any day now. I saw blue-gray gnatcatchers, yellow-throated warblers and a few shorebirds, including a greater yellowlegs. All of these birds usually migrate through Northeast Tennessee and Southwest Virginia in April and early May.

I also saw some coastal specialties that don’t usually come close to my landlocked home state of Tennessee, including anhinga, tricolored heron and brown pelican.

The brown pelican is the smallest of the world’s eight species of pelicans, which are grouped in the family Pelecanidae. Saying that a brown pelican is small, however, is a relative term. The brown pelican is about half the size of the related white pelican.

The brown pelican lives on both coasts, from around Seattle, Washington, and Cape Cod, Massachusetts, southward to the tropics. This pelican also lives along the Gulf Coast, as well as ranging south as far as the mouth of the Amazon River in South America.

According to the U.S. Fish & Wildlife Service’s website, there are two geographically and genetically distinct regional populations, or subspecies, of brown pelican that occur in North America. They are the California brown pelican, ranging from California to Chile, and the eastern brown pelican, which occurs along the Atlantic and Gulf coasts, as well as the Caribbean and the Central and South American coasts.

Pelicans have been documented living about 30 years in the wild, but the average age may be much less due to factors such as predation, disease and starvation. Many young pelicans, unskilled at catching fish, sadly do not reach adulthood.

DDT, which negatively affected breeding for birds such as bald eagle, osprey and peregrine falcon, also had a detrimental impact on the brown pelican. According to their website, in 1970, the U.S. Fish and Wildlife Service listed the brown pelican as endangered. The listing was possible through a law that had been passed before 1973’s Endangered Species Act. A recovery plan was published in 1983. In November 2009, the pelican was removed from the Endangered Species List, becoming another success story akin to that of the bald eagle.

Summer-Pelicans

Photo by Bryan Stevens • Brown pelicans fly in a line over the Atlantic Ocean on the South Carolina coast, conjuring forth fantasies of ancient flying creatures.

Visitors to beaches along the Atlantic Coast have probably seen the impressive flight of brown pelicans in a single file formation of birds gliding only a few feet above the surf. The span of the wings can reach seven feet six inches. Seen near dusk, an observer could be forgiven a flight of fancy that allows these pelicans and their graceful flying formations to be compared to the long-extinct flying reptiles, the pterosaurs.

At a distance, the birds can readily be described as majestic and even graceful. On closer inspection, some different adjectives come into play to describe the brown pelican. At close quarters, a brown pelican is an ungainly, almost ugly bird. Pelicans have long necks and bills, and on land, they shuffle awkwardly. Young bird are drab brown and gray, often looking much more disheveled than adult birds.

IMG_4340

Photo by Bryan Stevens • A large pouch that is connected to its bill is one physical trait that makes pelicans distinct from other birds. Although these birds often appear ungainly, they are quite skilled at using their pouch-equipped bill to capture fish.

According to the website All About Birds, the brown pelican feeds mostly on small fish such as menhaden, mullet, anchovies, herring, and sailfin mollies. These large birds may plunge from 65 feet above the surface of the water to capture fish in their famous throat pouch. In addition to fish, a pelican can take up to 2.6 gallons of water into its pouch with every dive. The water gets expelled, leaving behind the fish.

When not feeding, pelicans will rest on sandbars, pilings and rock jetties. These “loafing” spots are important places for pelicans to rest and recuperate after the rigors of diving and fishing for their fish meals.

IMG_4342

Photo by Bryan Stevens • A young brown pelican fishes along the causeway at Huntington Beach State Park. These birds capture fish in an elastic pouch that is attached to their bills.

The closest avian relatives of the pelicans are a couple of oddball birds known as the shoebill and hamerkop. The world’s other species of pelicans include Peruvian pelican, great white pelican, Australian pelican, American white pelican, pink-backed pelican, Dalmatian pelican and spot-billed pelican.

One state — Louisiana — has even made the brown pelican its official state bird. Most state birds are songbirds. The brown pelican is one of the exceptions, along with such birds as Minnesota’s common loon and the wild turkey, which has been adopted by Massachusetts.

IMG_4339

On a handful of occasions, brown pelicans have made brief appearances in the region, usually generating a great deal of excitement among birders. White pelicans are also rare visitors, but they make slightly more stops in the region than their smaller relative. For instance, a white pelican spent a few days at Middlebrook Lake in Bristol around Thanksgiving in 2015. To increase your odds of observing a brown pelican in the wild, it will be much more productive to simply spend a few days along the coasts of Virginia, North Carolina, South Carolina, Georgia or Florida.

North America’s bluebirds never fail to impress with their winning ways

A famous song declares that “somewhere over the rainbow, bluebirds fly,” so you’ll have to excuse me if I have been looking for those elusive rainbows during the unseasonably warm weather the region’s enjoyed in recent weeks.

Also, like the song promises, “dreams really do come true,” which was fulfilled by the arrival of this year’s first pair of Eastern bluebirds at my home on Friday, Feb. 23. The presence of a pair of these beautiful and trusting birds is always sure to put people in a good mood. People have known for generations that bluebirds make good neighbors. A pair of bluebirds in your yard or garden provides hour upon hour of free entertainment as one watches these birds go about their daily routine. At this time of the year, much of that routine is focused on finding and claiming the best possible nesting location for the upcoming spring season.

Bluebird-Comic

The Eastern bluebird is one of the most beloved American songbirds.

The Eastern bluebird is one of North America’s best-known cavity-nesting birds. About 85 species of North American birds use cavities in trees for nesting purposes. Cavity-nesters include ducks, such as buffleheads and wood ducks, as well as birds of prey such as Eastern screech-owls and American kestrels.

Woodpeckers and nuthatches can excavate their own cavity in a dead or decaying tree. Others, such as the bluebirds, must find a cavity already in existence. Such cavities are scarce real estate and can be subject to some intense competition. The Eastern bluebird is at a disadvantage when forced to compete with non-native introduced birds such as aggressive European starlings and house sparrows. Even native competitors such as house wrens and tree swallows are serious rivals when it comes down to staking a claim to prime nesting real estate.

Over the years, I have found bluebirds nesting in cavities inside wooden fence posts, but there are fewer wooden fence posts every year. This reinforces the idea of how changing landscapes have affected these birds. Instead of wooden fence posts, many farmers now use metal ones, and dead or dying trees — a much sought-after resource for cavity-nesting birds — are often removed from woodlands.

Bluebird-withPineNeedles

Photo by Bryan Stevens • A female Eastern Bluebird gathers pine needles to use as nesting material.

Fortunately for bluebirds, this species will also accept lodging in a nest box, or birdhouse, provided for them by human landlords. One of the simplest ways to bring bluebirds close is to offer wooden boxes, constructed to their specific requirements, for their use as nesting locations. Because of their trusting nature when it comes to their human neighbors, the Eastern bluebird is one of our most beloved birds. In fact, bluebirds are such popular birds that interest in them and their well-being has inspired the foundation of organizations such as the North American Bluebird Society. The Eastern bluebird has also been designated the official state bird for New York and Missouri, which provides more testimony to the immense popularity of this bird.

Bluebirds-One

Photo by Bryan Stevens • A flock of Eastern bluebirds perches on fenceposts.

There are two other species of bluebirds found in North America. The Western bluebird is found throughout the year in California, the southern Rocky Mountains, Arizona and New Mexico, as well as in part of Mexico. The species ranges in the summer as far north as the Pacific Northwest, British Columbia and Montana. The Mountain bluebird nests in open country in the western United States as far north as Alaska. They are short-distance migrants, retreating as far south as Mexico during the winter season.

Other than these three species, North America offers few others birds with mostly “blue” plumages. Some examples include indigo bunting, blue grosbeak, and blue jay, as well as birds like great blue heron and belted kingfisher.

In addition to housing, food and water can be used to lure Eastern bluebirds closer. This bird doesn’t eat seeds, but it can be attracted with an offering of mealworms — live or freeze-dried – or commercially prepared peanut butter nuggets. A water feature in a yard is also a magnet for bluebirds and a host of other bird species.

Bluebird-Pool

Photo by Bryan Stevens • A handsome male Eastern bluebird perches on a chain-link fence.

If your home doesn’t provide suitable open, spacious bluebird habitat, it’s still easy to enjoy these beautiful birds. An afternoon or evening drive into open country, such as agricultural farmland, is likely to yield sightings of this bird on fences and utility lines. Golf courses, some of which go the extra mile to accommodate bluebirds, also provide habitat for these lovely birds.

The Eastern bluebird is present in the region in all seasons and is one of our more common birds. If you’re already an experienced landlord and host for these birds, you probably already know they joys they can bring. If not, why not try to attract them closer to you? Most bluebirds in the region have already started looking for a nesting site. Many of these birds may nest two or even three times in a single season. March has only just arrived, so there’s still time to place a nest box or two on your property to get their attention.

Unlikely orange-crowned warbler becomes daily visitor this winter at woman’s feeders

After you have fed the birds long enough, you’re going to get visits from “mystery” birds. No matter how thoroughly you thumb through the pages of your field guides or how many online Google searches you conduct, it can be hard to pin down the identity of certain birds, especially when you encounter them for the first time.

Orange-crowned-Two-BOYD

Photo by Rebecca Boyd • This orange-crowned warbler has found a favorable winter residence at the home of Rebecca Boyd in Knoxville, Tennessee, making frequent visits to suet feeders to supplement its usual diet of insects and berries.

In the summer and fall, young birds recently out of the nest can cause some confusion when they show up in the company of their parents at feeders. In the winter, often a season characterized by subdued plumages and nomadic wanderers, the surprise visitors can be one of the many “little brown birds” in the sparrow clan or a summer bird like an oriole or thrush that has decided to take a shot at overwintering.

Or, with greater frequency each winter, it might be one of the warblers. That was the case when Rebecca Boyd, a resident of Knoxville, Tennessee, contacted me recently via Facebook asking for assistance with a bird identification.

Photo by Rebecca Boyd • This orange-crowned warbler is one of the more nondescript members of the warbler family.

Although most of the warblers beat a hasty retreat from North America every fall, a handful of species have increasingly begun to spend the winter months far north of their usual tropical haunts. Some of these species include yellow-rumped warbler, pine warbler and palm warbler, but the low-profile orange-crowned warbler is also becoming more common between November and March, especially in yards and gardens offering supplemental food such as suet cakes.

The small greenish-yellow bird that showed up at Rebecca’s home was easily identified, thanks to some great photographs that she took of her visitor. I communicated to her that I believed her bird to be an orange-crowned warbler. She had also conducted her own research, which had also led her to that conclusion.

Orange-crowned-Four-BOYD

Photo by Rebecca Boyd • This orange-crowned warbler has found a home at the residence of Rebecca Boyd in Knoxville, Tennessee, this winter.

Rebecca said she also shared some photos with birding groups on Facebook, which brought some helpful feedback. “I’ve gotten numerous responses that orange-crowned warblers are becoming a lot more common on the east side of the Mississippi, with quite a few people saying they are seeing them in their yards, too,” Rebecca wrote.

The orange-crowned warbler is one of the more undistinguished members of this New World family of birds that numbers about 115 species. The bird gains its common name from a physical feature that is rarely seen — an orange patch of feathers that, unless the bird is extremely excited or agitated, is usually concealed beneath its dull greenish-yellow feathers. It’s not a field mark that’s considered reliable for identifying the bird.

Rebecca got a lucky break and managed to photograph this elusive feature on her visiting bird. She said the feathers on the bird’s head appeared wet, which may have explained the appearance of the orange crown.

Photo by Rebecca Boyd • Wet feathers made the rarely seen orange crown visible on this orange-crowned warbler that has taken up residence at the home of Rebecca Boyd in Knoxville, Tennessee, this winter.

So, what does signify an orange-crowned warbler? The lack of wing bars, as well as the absence of a strong facial pattern is a strong indicator. The bird in Rebecca’s photo is not nearly as drab as this warbler can appear. Some appear very gray with only a hint of yellow or green in their plumage. There is often faint gray streaking evident in their yellow-green breast feathers. This warbler always shows yellow beneath its tail, a feature that is often only glimpsed as an observed bird is diving into cover. These birds also have sharp, thin bills. It’s usually a process of eliminating other suspects that brings birders to identify one of these warblers.

Unlike some warblers restricted to either the eastern or western United States, the orange-crowned warbler migrates and winters throughout the nation, east and west, although it primarily only nests within the western United States, as well as Alaska and Canada.

Although Rebecca said she has only been bird-watching and taking pictures for a little over a year, she has been a general point-and-shoot photography hobbyist for years. “My backyard is a bird paradise that attracts numerous and varied species,” Rebecca noted. “My favorites are bluebirds and hummingbirds, but the little warblers are also very special.”

Orange-crowned-One-BOYD

Photo by Rebecca Boyd • Besides orange-crowned warbler, like this individual, other warblers on occasion winter in the United States. Species most often attempting to spend the winter months in the United States include palm warbler, pine warbler, and yellow-rumped warbler.

Most of the warblers are currently residing on the island of the the Caribbean, or far south in Central and South America. A few others spend the winter in Florida or other southern states. The 50 or so species that nest in the United States and Canada will begin arriving as early as next month, although the majority of these summer residents will arrive or pass through the region in late April and May.

So, while it has a colorful name, the orange-crowned warbler is one of the more drab and nondescript members of its family. Other warblers living throughout the Americas include flame-throated warbler, crescent-chested warbler, citrine warbler and arrowhead warbler.

I’ll just keep daydreaming on the occasional snowy day of the approach of spring, which signals that the kin of the orange-crowned warbler will be winging their way north again in only a couple more months. I, for one, can’t wait.

Duck…duck…goose? Winter season good time for finding rare geese in the region

Of the geese found in the region, the well-known Canada goose is nearly ubiquitous. That’s not always been the case. For instance, in his book The Birds of Northeast Tennessee, Rick Knight points out that the geese now present throughout the year resulted from stocking programs conducted in the 1970s and 1980s. In earlier decades, the Canada goose was considered a rare winter visitor to the region.

Seeing the Canada goose in every sort of habitat from golf courses to grassy margins along city walking trails, it’s hard to imagine a time when this goose wasn’t one of the region’s most common waterfowl.

Early American naturalist and artist John James Audubon captured this pair of Canada geese in a most realistic painting.

The world’s geese are not as numerous as ducks, but there are still about 20 species of geese worldwide, compared to about 120 species of ducks. While both ducks and geese are lumped together as waterfowl, most geese are more terrestrial than ducks. Birders are just as likely to spot geese in a pasture or on the greens of a golf course as they are on a lake or pond.

There have been several species of geese usually considered rare to uncommon in the region that have been spotted by birders thus far this winter season. I personally observed greater white-fronted geese at several different locations in November and December.

The greater white-fronted goose is considerably smaller than a Canada goose. The bird is named for the distinctive white band found at the base of bill. This white band also helps distinguish this goose from similar domestic geese. The sexes are similar in appearance, but females are usually smaller than males. The head, neck and upper back of white-fronted geese are grayish-brown. The lower back and rump are dark brown, and the tail is dark brown and edged with white. The chest and breast are grayish with dark brown to black blotches and bars on the breast, giving this goose the nickname “specklebelly.” The bill is pinkish and the legs and feet are orange.

Canada-Greater

The greater white-fronted goose breeds in North America as well as in Europe and Asia, and they spend the winter throughout the United States and even in Japan. Most nesting in North America takes place on the North Slope of Alaska and across the western and central Canadian Arctic. Wintering habitats include coastal marshes, wet fields and and freshwater wetlands.

Only a couple of weeks ago, I spotted a snow goose at the fish pond located at Erwin Fishery Park. The snow goose is a North American goose known for its white plumage that gives the bird its common name; however, the snow goose actually comes in two versions: the white phase and a blue phase, which is often referred to as a “blue goose.”

The snow goose breeds in regions in the far north, including Alaska, Canada, Greenland and even the northeastern tip of Siberia. They may spend the winter as far south as Texas and Mexico, although some will migrate no farther than southwestern British Columbia in Canada.

The snow goose bucks the trends that show many species of waterfowl declining. Recent surveys show that the population of the snow goose exceeds five million birds, which is an increase of more than 300 percent since the mid-1970s. In fact, this goose is thriving to such a degree that the large population has begun to inflict damage on its breeding habitat in some tundra regions.

A smaller relative to the snow goose is the Ross’s goose, which for all practical purposes looks like a snow goose in miniature. The common name of this goose honors Bernard R. Ross, who was associated with the Hudson’s Bay Company in Canada’s Northwest Territories.

Here’s a quick history lesson. Hudson’s Bay Company is the oldest commercial corporation in North America. The company has been in continuous operation for more than 340 years, which ranks it as one of the oldest in the world. The company began as a fur-trading enterprise, thanks to an English royal charter in back in 1670 during the reign of King Charles II. These days, Hudson’s Bay Company owns and operates retail stores throughout Canada and the United States.

In addition to his trade in furs, Ross collected specimens for the Smithsonian Institution in Washington, D.C. Ross is responsible for giving the goose that now bears his name one of its early common names – the Horned Wavy Goose of Hearne. I wonder why that never caught on?

Ross repeatedly insisted that this small goose was a species distinct from the related and larger lesser snow goose and greater snow goose. His vouching for this small white goose eventually convinced other experts that this bird was indeed its own species.

Ross was born in Ireland in 1827. He died in Toronto, Ontario, in 1874. He was described by other prominent early naturalists as “enthusiastic” and “a careful observer” in the employ of Hudson’s Bay Company. When John Cassin gave the Ross’s Goose its first scientific name of Anser rossii in 1861, he paid tribute to the Hudson’s Bay Company’s Ross.

Photo by Bryan Stevens • In some areas, Canada geese have become so prevalent that they are considered pests. Human handouts to waterfowl are not always compatible with good health for the birds that receive them.

The Ross’s goose has a “cuteness” factor working in its favor. For a goose, it is rather small. It could best be described as a snow goose in miniature. In fact, it isn’t much larger than such ducks as mallards and is considered the smallest of North America’s geese.

The Ross’s goose has also acquired some other common names, including “galoot” and “scabby-nosed wavey.” This latter name was inspired by the bird’s bill, which is covered with rough bumps around the base. I have to admit that “scabby-nosed wavey” is a name likely to stick in the memory. Today, the Ross’s goose’s scientific name is Chen rossii.

Other geese found worldwide include the pink-footed goose, bar-headed goose, emperor goose, red-breasted goose and barnacle goose.

So, does this inspire you to try a wild goose chase of your own? If it does, best of luck in your efforts.
