Phoebe’s return a signal other arrivals due soon

1 Reply

An Eastern phoebe has returned to the woodlands around my home.

I’m not sure when the resident phoebes departed last fall. They were still prominent in their daily activities in late October and early November. I think they probably slipped off, unnoticed, around Thanksgiving. Some winters, a few Eastern phoebes linger throughout the cold months, often near an open source of water that’s unlikely to freeze.

With the arrival of March and warmer weather, at least one Eastern phoebe, a male, is back and singing tirelessly every morning. The song is easy to memorise. The singing bird simply repeats its name — fee bee, fee bee — in scratchy, descending sets of tones.

Considering the bright finery worn by some of the more colorful spring arrivals, Eastern phoebes are comparatively drab. The gray and white plumage of this species of flycatcher pales in comparison with vibrant birds like rose-breasted grosbeak, ruby-throated hummingbird, scarlet tanager and yellow warbler.

Nevertheless, this member of the flycatcher clan has earned itself a favorite spot in the hearts of many a birdwatcher. It’s one of those birds that even beginning birders find surprisingly easy to recognize and identify. While it may not have a dramatic plumage pattern to hint at its identity, the Eastern phoebe is quite at home around human dwellings and comes into close contact with people going about their daily routines. Rather tame — or at least not too bothered by close proximity with humans — the Eastern phoebe has one behavior that sets it apart from all the other similar flycatchers. When this bird lands on a perch, it cannot resist a vigorous bobbing of its tail. Every time that a phoebe lands on a perch, it will produce this easily recognized tail wag. It’s this tell-tale action that makes this bird almost instantly recognizable among birders with the knowledge of this behavioral trait.

The Eastern phoebe, known by the scientific name of Sayornis phoebe, has two relatives in the genus Sayornis. The genus is named after Thomas Say, an American naturalist. The Eastern phoebe’s close relatives include the black phoebe and Say’s phoebe. The black phoebe ranges throughout Oregon, Washington and California and as far south as Central and South America. As its name suggests, this bird has mostly black feathers instead of the gray plumage of its relatives. The Say’s phoebe, also named for the man who gave the genus its name, is the western counterpart to the Eastern phoebe.

Since they belong to the vast family of New World flycatchers, it’s probably no surprise that these phoebes feed largely on insects. That’s why phoebes overwintering in the region are always found near water. The open water also attracts flying insects. The birds will often perch patiently until an insect’s flight brings it within easy range. A quick flight from its perch usually allows the skillful bird to return with a morsel snatched on the wing. In the winter months, however, the Eastern phoebe also eats berries and other small fruit when insect scarcity makes this exclusive diet almost impossible.

Phoebes are fond of nesting on human structures, including culverts, bridges and houses. With the latter, they were once known for their habit of placing their nests under sheltering eaves. At my home, a pair of Eastern phoebes often chooses to nest on the wooden rafters in my family’s garage. Phoebes also like to reside near a water source, such as a creek, stream or pond.

Although the species is migratory, a few hardy individuals will usually try to tough out winters in the region. The others that depart in the autumn will migrate to the southern United States and as far south as Central America. On some rare occasions, Eastern phoebes have flown far off their usual course and ended up in western Europe. I can usually count on Eastern phoebes returning to my home in early March, making them one of the first migrants to return each year.

This year, like the dependability of clockwork, I began hearing that easily recognized song on mornings during the first days of March when I walked to my car to depart for work. It’s due to their noisy nature that their arrival rarely goes unnoticed. Males tend to start singing persistently as soon as they arrive. I doubt it will take the male residing near my home long to attract a mate.

John James Audubon, an early naturalist and famed painter of North America’s birds, conducted an experiment with some young phoebes. His simple test represents the first-ever bird banding in the United States of America. His novel experiment, which he carried out in 1803, involved tying some silver thread to the legs of the phoebes he captured near his home in Pennsylvania. He wanted to answer a question he had about whether birds are faithful to home locations from year to year. The following year Audubon again captured two phoebes and found the silver thread had remained attached to their legs. Today ornithologists still conduct bird banding to gather information on birds and the mystery of their migrations.

So, that pair of phoebes that returned to your backyard this spring — they just might be the same ones that have spent past summer seasons providing you with an enlightening glimpse into their lives.

Over the past few years, I’ve had a pair of Eastern phoebes nest on the blades of a ceiling fan on my front porch. Other past nesting locations have included the rafters in my garage. If a pair happens to take up residence on your own front porch or in your garage, I hope you’ll welcome them. The pleasure of observing them raising their family will more than compensate for a slight mess and a few weeks of inconvenience.

Red-winged blackbird, other birds set to return in coming weeks

Leave a reply

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

February’s the shortest month, and it is more than halfway over. There are already signs that some birds are ready to embrace the shift in seasons as winter advances, albeit in fits and starts, toward spring.

On Feb.11, three mallards visited my fish pond. The presence of mallards at any pond is not all that surprising. The mallard is arguably the most recognized of North America’s native ducks. But these were wild birds, as indicated by their wary behavior and their ability to spring into strong flight when I surprised them quite by accident.

Spring migration begins as early as February and March. Eastern bluebirds, which for the most part are not migratory, are already checking out nesting boxes.

The months of March, April and May will bring an influx of migrants. Ruby-throated hummingbirds will soon make their annual crossing of the Gulf of Mexico. These tiny birds usually make landfall in the United States as early as February, but they don’t usually venture as far north as Northeast Tennessee, Western North Carolina and Southwest Virginia until early April.

Bryan Stevens • On Feb.11, three mallards visited my fish pond. I am hoping they are the start of more migrating birds arriving in the coming weeks.

Warblers, orioles, thrushes, flycatchers, tanagers and many other migrants also return in April and May. A variety of waterfowl, raptors and shorebirds pass through the region during these months, as well.

March brings the early birds, including species such as brown thrasher, blue-gray gnatcatcher and red-winged blackbird.

Red-winged blackbirds return with a venegeance in early March or sometimes in late February.

I’m ready to hear their loud, familiar “kon-ke-ree” sounds again from the tops of the cypress trees at the fish pond. It’s always a fun moment to welcome these birds back.

Red-winged blackbirds return yearly in early spring and begin to seek out nesting habitat in local wetland areas, such as the cattail marshes near my fish pond.

My first returning male red-winged blackbird arrived on the evening of March 3 in 2022. The first red-winged blackbird arrived on the morning of March 6 the following year. I heard his unmistakable song from inside my house.

The showy and loud red-winged blackbird males soon take up residence at my fish pond and adjacent stands of cattails after their return.

Male blackbirds arrive ahead of the females. They immediately search out prominent perches and begin singing every day in anticipation of an intended audience. Female blackbirds lag a week or so behind the males in returning to their familiar territory.

Any wet field or marsh, especially those offering a stand of cattails, is almost certain to attract red-winged blackbirds at this time of year. I’d almost wager on that certainty.

The blackbirds arriving in spring behave much differently than the quiet, furtive flocks that often make brief visits to feeders during late winter snowstorms.

“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 located at the Tennessee Watchable Wildlife website.

At this time of year, the male red-winged blackbirds seek elevated perches to display and vocalize. Their loud antics are not designed solely to attract mates. Male red-winged blackbirds also sing to warn rival males from intruding into their territories.

The male red-winged blackbird 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.

Red-winged blackbirds are fond of wetlands. Any marsh or even a 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 as females in feeding and tending their young. Males 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.

According to the website All About Birds, male red-winged blackbirds spend much of the breeding season sitting on a high perch over their territories and singing almost without ceasing from dawn to dusk.

The website also notes that female blackbirds shirk the high profile of the males. They tend to skulk in wetland vegetation as they collect food or nest material.

Bryan Stevens • Female red-winged blackbirds lack the showy plumage of males. They look more like an overgrown sparrow.

Both males and females defend nests from intruders and predators. They take this duty quite seriously, as I know personally from being dive-bombed by parent blackbirds when I have gotten a little too close to their nests.

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.

For birders, the weeks ahead are an exciting time. In spirit, I think others often join our excitement if for no other reason than to celebrate that spring is just around the corner. These “early bird” arrivals are merely the harbingers of the season.

Birds make use of various strategies to attract and keep mates

Leave a reply

Shauna Fletche/Pixabay • Some birds, like waxwings, like to present tasty treats to their potential mates.

 

With Valentine’s Day around the corner, it’s an opportune time to see how courtship is handled among our fine feathered friends. Most birds don’t bring a box of chocolates or a bouquet of roses when they take up courtship of a prospective mate, but birds have several equivalent behaviors that they employ to attract the attentions of the opposite sex. In honor of Valentine’s Day I thought a look at some of the more unusual courtship rituals of some of our feathered friends would be appropriate.

Aerial acrobatics designed to impress

In late winter and early spring, a true oddball begins courting. The American woodcock, also known by such whimsical names as “bog sucker” and “timberdoodle,” is a shorebird that has completely abandoned the shore in favor of woodlands and fields. Beginning as early as February, American woodcocks in the region conduct nightly courtship displays, starting at dusk, that combine aerial acrobatics with an assortment of unusual acoustical flourishes. Any wet field adjacent to a wooded area could offer a stage for these evening displays, but unless you know where to look and make an effort to do so, the American woodcock might as well remain a phantom of the night.

These mating rituals provide almost the only time of the year during which this bird makes itself available for observation. It’s only during this brief window that opens into their lives that we can be assured a glimpse. Even then, our peeks at woodcocks often consist of a fuzzy twilight escapade as the bird flings itself heavenward only to make a spiraling descent a few seconds later. The displays begin with a distinct vocalization, a type of “pent,” that also has the quality of sounding like some sort of mechanical buzzer.

Once the displays conclude for the season, the birds assume nesting duties, usually unobserved by humans. The rest of the year, almost nothing but blind, sheer luck would allow a birder to stumble across an American woodcock. It’s almost as if they disappear after these spring flights of fancy.

Birds bearing gifts

Many birds present small trinkets to a prospective mate. For instance, many male penguins make a present of a stone or pebble to female penguins. There could be more than a simple bribe behind this gift. Female penguins don’t build elaborate nests. In fact, a scrape on the bare ground, perhaps encircled by a collection of pebbles, marks the extent of their nest construction. So, the perfect pebble could be the way to winning a female penguin’s heart.

The way to the heart is through the stomach

Observant birders may have witnessed a male Northern cardinal slip a female a morsel of food, such as a peanut or a shelled sunflower kernel. It’s a marked change for this bird. During the winter months, a male cardinal is more likely to chase a female away from a feeder rather than share food with her. However, as spring approaches, his behavior undergoes a change and he becomes content to feed next to a female cardinal, often slipping her some choice tidbits.

Sabine van Erp/Pixabay • Bow to your partner: Grey-crowned cranes perform an elaborate dance designed to strengthen their bond.

May I have this dance?

Many species of birds perform elaborate and ritualistic dance displays. Among birds known for tripping the light fantastic are flamingoes, cranes, grouse and grebes. Cranes are one of the oldest families of birds on earth. They’re also some of the most accomplished dancers in the animal kingdom. Pairs perform very ritualistic dances that, if the performers were human, would no doubt require the services of an accomplished choreographer. Cranes mate for life and the ritual of dancing is a way to strengthen the bonds between a mated pair. The ability to dance is, apparently, not instinctive. Young cranes must practice their dance moves, a process that can take years before they master the elaborate dance.

Dave Menke/U.S. Fish & Wildlife Service • A pair of Clark’s Grebes displays in a courtship ritual known as “rushing” or “weed dance.” Birds use a variety of strategies to attract and keep mates.

Synchronized swimming

While many birds dance to impress a mate or strengthen pair bonds, grebes perform a dance that takes place completely on the surface of the water. A pair will engage in this intricate performance, perfectly mirroring the moves of the other as they literally race across the surface of the water. These dances by grebes are also known as “rushing” or “weed dance.” It’s called as a weed dance because at the culmination of the ritual, the birds usually hold some type of aquatic plants in their bills while racing swiftly over the surface of the water. Pairs that perform well together stay together, building a nest and raising young.

Good housekeeping seal of approval

The tropical family of bowerbirds are famous for complex nests built by males and then decorated with bright and colorful objects to catch the eye of a potential mate. The nests of these birds are actually referred to as a “bower.” Usually constructed on the ground, the male will line the approachs to the bower with items such as shells, leaves, flowers, feathers, stones, berries, and even discarded garbage, including plastic scraps or bits of glass. Unusually odd items pressed into these decorative displays have included coins and spent rifle shells. This habit of male bowerbirds must rank as the ultimate in trying to impress a mate with shiny bling.

These are just a few of the inventive ways that birds go about attracting and keeping mates. Perhaps you can pick up some pointers from our feathered friends to ensure you have a great Valentine’s Day this year.

Birds have developed ways of dealing with cold

Leave a reply

David Ellis/USFWS • A common redpoll feasts on stiff goldenrod seed. These small finches can endure temperatures 100 degrees below freezing.

With the arrival of January, we can probably be assured of some cold weather. I’m not fond of the cold, but I can put on gloves and a thicker coat and I am good to go.

What about our feathered friends? How do birds cope when temperature plummet below freezing?

Birds actually employ a range of strategies and behaviors that keep them cozy even during the worst that winter can hurl at them.

Some birds avoid the necessity of coping with cold by migrating. All those tropical species that brighten the warmer seasons in the mountains of Southern Appalachia withdraw to warmer areas in Central and South America during the winter.

Those birds that elect not to put distance between themselves and cold temperatures must do something to stay warm. Feathers are one of a bird’s defining traits, and they can do a neat trick with their feathers to stay warm. You’ve probably seen them do this. They will fluff their feathers, trapping air between them to provide insulation. If you’ve ever noticed that some birds look “fatter” in extreme cold it’s likely because they have fluffed up to combat the cold.

Of course, feathers require good maintenance to help with the task of staying warm, and birds are diligent about such tasks. Preening feathers on a routine basis keeps them watertight and able to hold in heat. Some birds even grow extra feathers in autumn to prepare for cold temperatures. That’s similar to dogs or cats growing a denser coat of fur in anticipation of wintry temperatures.

Birds have different comfort levels when its comes to personal space, but many of the more sociable species will huddle together. You’ve probably seen nature documentaries of penguins in the Antarctic as they huddle together for weeks on end to endure the harsh conditions of the globe’s southernmost continent.

Larger species of birds, such as geese and grouse, eat more and gain weight, which is often achieved by the storage of body fat.

Other birds have also adopted the huddling strategy in a cozy cavity or nest box. My most vivid recollection of an observation of this strategy involved Eastern bluebirds. During a severe cold snap accompanied by snow and blustery winds, I watched multiple bluebirds enter one of my nesting boxes. I’m not sure how many entered the box, but it was likely about eight to 10 birds.

Necessity makes birds adaptable. The next day the aforementioned high winds took down the post that held the nest box. At dusk the bluebirds showed up again. They looked baffled to find the box had disappeared. Then I saw them fluttering into an old tire that I had used at the base of the pole to help anchor the box. Faced with oncoming darkness, they chose to huddle together inside the old tire.

Natural cavities in trees also provide cozy roosting spaces for birds. Chickadees and titmice, nuthatches and woodpeckers seek out such cavities ahead of time so they will always be ensured of a warm space during bouts of inclement weather.

The biological mechanism of torpor is one that’s probably familiar to fans of hummingbirds, but other small birds can also take steps to lower their body temperature. Chickadees and kinglets put this ability to good use. In these small birds, the adaptation being employed is known as controlled hypothermia. Chickadees can drop their body temperature by as much as 22 degrees below normal daytime body temperature.

Snakes and reptiles can enter a physical state called brumation, where they sleep more but still wake to eat, drink and enjoy the sun on warmer days, according to information on the Facebook page of the U.S. Fish and Wildlife Service. Since snakes are cold-blooded, they’re lethargic at these colder temperatures even when they’re on the move.

Hibernation, although a strategy widely used by mammals, is rare in birds. The common poorwill (a relative of whip-poor-will and chuck-will’s-widow – is the only bird known to go into torpor for extended periods that can range from weeks to months. On the southern edge of their range in the United States, poorwills spend much of the winter hibernating, usually concealed in rock piles.

There’s warmth in numbers. Crows, starlings, robins and other species will gather in communal roosts to use body warmth to stay warm overnight. Sometimes these roosts are quite large and can lead to conflict with nearby humans who may not want the noise and mess that comes with hosting a large flock of birds.

While warm socks and gloves protect human toes and fingers, birds don’t have to worry about frostbite. Quick circulation means that blood does not linger in their feet long enough to freeze. In addition, the legs and feet of birds are covered in scales. Like feathers, the scales provide excellent insulation.

Some birds will gather together in large stands of evergreens. I’ve observed house sparrows gathering in the holly trees outside the courthouse in downtown Erwin at dusk on cold evenings.

There are things we can do to help. Plant evergreen trees or construct a brush pile that will provide shelter from the elements, as well as a measure of safety from predators, for the birds that share our lawns and gardens.

Many people already feed birds. Try supplementing seeds with some food rich in fat. Birds, unlike us, will not be adversely affected by a high-fat diet. Their metabolism allows them to burn off the extra calories in an enviable amount of time. Some high-fat foods that birds will love include peanut butter and beef suet, as well as peanuts and other assorted nuts. While it’s relatively simple to render suet into a usable for for birds, most people cannot be blamed for turning to commercially made suet cakes. Many of these are also made even more appealing with a mix of peanuts or fruit into the suet cake. The extra calories derived from these foods will let birds better regulate their body temperature and tolerate the more frigid nights.

It’s also important to provide liquid water for birds. Outdoor heaters designed to fit into a birth bath can help prevent the water from freezing during cold snaps.

Birds will also appreciate a sunny spot. By basking in sunshine, they can also boost their internal temperature.

Some birds are just built for cold. For example, snowy owls have been observed in temperatures 80 degrees below zero. Species of redpolls, a type of finch, can endure temperatures 100 degrees below freezing.

Emperor penguins live and nest in some of the most inhospitable terrain on the planet. Those who have viewed the documentary film “March of the Penguins” will be familiar with the species. Their colonies on the ice in the Antarctic must endure temperatures than can plunge to -40 degrees Farenheit. They must also survive frigid winds that can reach 90 miles per hour.

Emperor penguins have several adaptation to help them survive such cold conditions, according to the World Wildlife Fund. These penguins have two layers of feathers, a reserve of fat and beaks and flippers that are proportionally smaller than those for other penguin species.

Lee Karney/USFWS • The common raven can live in a range of habitats, but these large and intelligent birds are especially adapted to cold.

The common raven is another bird that shrugs off cold and snow. They can survive and thrive in habitats as varied as Arctic tundra and scorching deserts. If temperatures drop below -4 degrees Farenheit, ravens can generate extra body heat.

All things considered, birds are simply better at coping with cold than we are.

Kinglets are tiny birds with huge appeal

Leave a reply

Photo by Beth McPherson • A golden-crowned kinglet recovers in the photographer’s hand after striking a window.

With the recent cold weather, I’ve been seeing a few golden-crowned kinglets, as well as the closely related ruby-crowned kinglet, at my home.

Golden-crowned kinglets are fairly common winter birds. Ruby-crowned kinglets, although not always as common as their relative, also are found in the region during the winter season.

Both the golden-crowned and ruby-crowned kinglets are members of a family of tiny birds known collectively as kinglets and firecrests. They’re such tiny, energetic birds that they absolutely excel with the “cuteness” factor.

All kinglets are very tiny birds, as well as extremely active ones. They are also the only members of this family of birds found in North America. Four other species, however, are native to Europe, Asia and North Africa. The remaining species include goldcrest, common firecrest, Madeira firecrest and flamecrest, which is also known as the Taiwan firecrest.

Kinglets, as their name suggests, are tiny birds. In fact, about the only North American birds smaller than kinglets are some of the hummingbirds. The kinglets belong to the family, Regulidae, and the genus, Regulus. The family and genus names are derived from a Latin word, regulus, which means “rex,” or “king.” The name was apparently inspired by the colorful crown patches, often red, orange or gold, that resemble the royal “crowns” of kings.

Although similar in size and overall coloration, the ruby-crowned and golden-crowned kinglets are easily distinguished from each other. Side by side, the two species of North American kinglets are easy to identify. The golden-crowned kinglet has a striped facial pattern formed by bold black and white stripes. The ruby-crowned kinglet, on the other hand, has a bold white eye ring but no striping.

The golden-crowned kinglet has an orange crown patch, while the ruby-crowned kinglet has a red crown patch that is, more often than not, kept concealed. Both sexes of the golden-crowned kinglet possess an orange crown patch, but only the male ruby-crowned kinglet boasts a scarlet patch of feather atop the head.

Kinglets are active birds, foraging vigorously for small insects and spiders. When foraging, both kinglet species have a habit of flicking their wings over the backs. Even if you can’t get a good look at the birds, this behavior alone helps contrast them from other small birds, including some warblers and wrens.

Golden-crowned kinglets are widespread in the region during the winter. During the summer months, head to the slopes of some of the region’s higher mountains to look for these tiny birds that nest at the higher elevations of the Southern Appalachians.

Ruby-crowned kinglets can also be found in the region during the winter, but extreme cold weather will often force these less cold-hardy birds to eke out the winter months farther south.

Kinglets don’t typically visit feeders, but they do tend to join mixed flocks with membership consisting of such species as tufted titmouse, Carolina chickadee and white-breasted nuthatch. When traveling with such flocks, kinglets may visit the space around feeders but rarely take seeds or other fare offered at feeders.

In recent decades, perhaps assisted by the surge in the popularity of feeding birds, kinglets have been observed sampling such fare as suet cakes, peanut chips and scraps of sunflower seeds that have been shelled and dropped by other birds.

Normally, kinglets have a rather fleeting lifespan. These tiny birds can be considered old if they live three or four years. There are always exceptions. The oldest golden-crowned kinglet on record was six years and four months old. That individual, a male, was documented by a bird bander in 1976, according to the website All About Birds.

Kinglets are surprisingly tame at time and often exhibit as much curiosity about us as we display toward them. They’re very active birds, however, constantly moving from perch to perch. These bursts of hyperactivity can make them difficult to observe with any satisfaction since they so rarely remain still for long.

Vocal screech owls are pint-sized predators

Leave a reply

Photo by Bryan Stevens • An Eastern screech owl perches on a hemlock branch. These owls are much smaller than such relatives as great horned owl and barred owl.

It’s been my pleasure to enjoy almost daily serenades by an Eastern screech owl residing in the woods around my home. The small owl’s shivery wailing calls usually start around dusk and can continue at intervals throughout the night.

Back in September while I watched almost daily for migrants from a lawn chair, I heard on a couple of occasions the “early bird” owls calling occasionally from shady wooded areas. The owls tended to call more often during the daytime when conditions were overcast.

I always pause and listen when I hear the wailing and haunting vocalizations of the screech-owls that make their home in the woodlands that surround my home. I’m glad to have this small owl as a neighbor, but I fully realize that owls have suffered from a dark reputation in certain corners. The fact is, unless you are a small rodent or some sort of insect-sized prey, the Eastern screech-owl makes an excellent addition to the neighborhood.

On the verge of Halloween, a closer look at this small owl is warranted. An adult Eastern screech owl is usually only between six and nine inches in length. Many people upon first seeing a screech-owl assume it’s a baby owl. During past trips to Brookgreen Gardens in South Carolina, I have enjoyed attending the daily educational programs conducted by the zoo staff at Brookgreen. These programs are designed to introduce visitors to various examples of native wildlife. The presenter usually introduced a couple of animals to the audience. On several occasions, the show featured birds of prey, including hawks and owls.

Photo by Irene K-s/Pixabay.com • An Eastern screech owl keeps an eye on its surroundings.

Two of the shows during my visit to Brookgreen back in 2019 featured Lucy, an Eastern screech-owl, and people in the audience invariably asked if she was a baby owl. To their astonishment, they learned that Lucy was an adult screech-owl and unlikely to grow any bigger.

There are larger owls in our region, including the great horned owl and barred owl. Lucy and her kin must avoid these much larger owls, which would not scruple at making a meal of the much smaller owl.

Because of their small size, screech-owls prey on some comparatively small creatures, including insects, small rodents, amphibians, songbirds and reptiles. The Eastern screech-owl is also a cavity-nesting bird and will accept bird boxes provided by humans so long as the box’s entrance hole is customized to their size.

The screech owl is the owl most likely to encounter human beings. It’s an adaptable little feathered predator, just as much at home in the backyard and garden as it is in parks and woodlands. In addition to nesting in cavities, this owl roosts in them during the daytime hours. Look for roosting screech-owls in knotholes of trees or in unoccupied wood duck boxes. Although they come in two color phases — red and gray — both variations are quite capable of camouflage. When perched or roosting, these small owls blend remarkably with their surroundings.

The Eastern screech owl also produces a variety of odd wails and other vocalizations including a distinctive, trembling “whinny” call that is often made when the owl feels curious or alarmed. It’s a wavering, haunting call that is made after dark, most often at the hours closer to dawn and dusk. Imitating the call of a screech-owl or playing a recording is also a trick for getting some shy songbirds to show themselves. Screech owls are not-so-welcome co-habitants among my yard’s songbirds, which will flock to this owl’s call and band together to “mob” the predator and try to convince it to depart the immediate area.

As small as the Eastern screech-owl is, the United States is home to several other pint-sized owls, including Western screech-owl, Northern pygmy-owl, Northern saw-whet owl, flammulated owl and elf owl, which at six inches tall and a weight of less than an ounce qualifies as the world’s smallest owl.

Photo by U.S. Fish and Wildlife Service • The tiny Northern Saw-whet Owl nests on several of the region’s higher mountains.

Any time I finish listening to a calling owl and go back indoors for the evening, I reflect on the fact that screech-owls make good neighbors. Their prey preferences remove many nuisance insects and rodents from the habitat they share with humans as well as other wildlife. If you’re hearing an odd, winnowing call from the edge of the woods at your own home, there’s a good chance that you have one of these small owls as a neighbor.

Keep alert for these small owls and their larger kin as we observe this year’s Halloween holiday, as well as other days and nights throughout the year.

Sandpiper a surprise addition for summer bird count

Leave a reply

Photo by USFWS • A baby least sandpiper shelters beneath its dutiful mother. The aptly named least sandpiper is the smallest species of shorebird.

It’s not too often I get a chance to make a historic bird sighting, but that’s what happened on a recent Saturday while seated on a bench with Rob Armistead having a breakfast break while taking part in a seasonal bird survey in Elizabethton along the Watauga River.

I chose the location for the break because I knew that it has traditionally been a good spot to observe some unexpected species. Past good birds that I’ve observed along this section of the Watauga River have included orange-crowned warbler, yellow-throated vireo, sora, Baltimore oriole and red-headed woodpecker.

On this occasion, a tiny shorebird made an appearance, settling on some exposed rock formations. In April and May, these same rocks are great locations to find migrating spotted sandpipers and solitary sandpipers. 

The bird was smaller than these sandpipers and immediately stood out as a “peep,” a nickname that birders give to a group of small sandpipers that are all similar in appearance.

The one physical trait that help distinguish a least sandpiper from other “peeps” is leg coloration. Least sandpipers have greenish or yellowish legs in contrast to the black legs of other similar “peeps.”

In good light and at close range, Rob and I confirmed that the bird had greenish legs and were thrilled to add a least sandpiper to our own tally of observed birds.

The least sandpiper, as suggested by its name, is the smallest member of the sandpiper family. In fact, this sandpiper, which is not much bigger than a sparrow, is the world’s smallest shorebird. The least sandpiper weighs only a single ounce and is only five to six inches long. 

According to the website All About Birds, the least sandpiper migrates thousands of miles between its Arctic breeding grounds and wintering grounds as far south as Chile and Brazil.

In releasing the count compilation, official compiler Rick Knight made note of the fact that the least sandpiper represents a late migrant and the first-ever June record for the species in the five-county area. 

During the course of the day, Rob and I joined Brookie and Jean Potter for a trip to Holston Mountain, where we added some mid- to high-elevation species such as scarlet tanager, rose-breasted grosbeak, veery, Eastern wood-pewee, dark-eyed junco, ruffed course and chestnut-sided warbler.

My other personal highlight on this count was seeing three young Ruffed Grouse darting  across the road, one at a time, while riding on Panhandle Road to the top of Holston Mountain. Those three young grouse turned out to be the only grouse counted by any participants on the count.

The Unicoi County Summer Bird Count was conducted Saturday, June 18. I’ll provide the results of that count in an upcoming column. 

Tanagers are among world’s most colorful birds

A male scarlet tanager brightens shadowy woodlands with a flash of tropical colors yet remains mostly inconspicuous in the forest canopy.

The daily chorus of songbirds greeting the dawn is usually welcome unless I’m feeling particularly sleepy. Carolina wrens are one of the first birds in residence to sing each day. This time of year they get plenty of accompanists, including American robins, Eastern phoebes, Carolina chickadees, Northern cardinals, Eastern towhees, red-eyed vireos, indigo buntings, hooded warblers, ovenbirds and others.

As June arrived, however, I began to take notice of the absent voice of scarlet tanagers. It wasn’t until June 9 that I heard the first male scarlet tanager of the season singing from the wooded ridge behind my home.

In late April and throughout May, once the oaks, the maples, the poplars and other trees begin spreading out new green leaves to create a concealing woodland canopy, a familiar song can be heard from the treetops. 

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 robin stricken a bit hoarse with a sore throat.

The producer of the hoarse but melodic song is a scarlet tanager, one of the most showy birds of Eastern woodlands from April to early October. Like the warblers, vireos, flycatchers and other songbirds, the scarlet tanager is migratory. They spend the winter months in the tropical forests of Central and South America. The scarlet tanager is better attired than most birds to provide us a glimpse of what life must be like in the tropical rain forests, which are a riot of color and sound.

It takes only one sighting to sear the vision of these vibrant birds into our retinas, as well as into our memories. The scarlet tanager boasts a brilliant plumage of crimson red paired with black wings and tail. Of course, this is the male. 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 molting their feathers.

Although once nominated as a candidate for state bird by the school children of Minnesota, the scarlet tanager ultimately failed to gain the designation. Instead, as perhaps is fitting for the “Land of 10,000 Lakes,” the common loon represents Minnesota as official state bird.

The related summer tanager is less widespread in Northeast Tennessee, but males of this species are no less dramatic in appearance than the Scarlet Tanager. Male summer tanagers are a rosy-red over all their body. Females, with a dull greenish plumage, are relegated to the background. She can be distinguished from her counterpart, the scarlet tanager, because of their darker wings and larger bills.

The summer tanager holds the distinction of being the only all-red bird in North America. Birds like Northern cardinals and scarlet tanagers also have some black in their plumage.

I’ve seen summer tanagers at Steele Creek Park in Bristol and Willow Springs Park in Johnson City. Sadly, over the years my sightings of this attractive songbird have been few and far between. My most memorable observation of a male summer tanager took place many years ago during a spring visit to Fripp Island, South Carolina. Most of the summer tanagers I have observed in Northeast Tennessee have been females.

On the other hand, I usually have a few scarlet tanagers in residence around my home during the summer months. If the woodlands at my home fail to attract this bird, I can usually make a visit to higher elevations on Roan Mountain, Unaka Mountain or Holston Mountain to gain an exciting glimpse of this beautiful bird.

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.

In the western United States, the scarlet and summer tanagers are replaced by Western tanagers and hepatic tanagers. During a visit to Salt Lake City in Utah in 2006 I saw several Western tanagers.

Some of the world’s other tanagers are known by extremely descriptive names, including flame-colored tanager, green-headed tanager, golden-chevroned tanager, azure-shouldered tanager, fawn-breasted tanager, saffron-crowned tanager, metallic-green tanager, turquoise tanager, scarlet-bellied mountain tanager and diademed tanager.

Scientists have recently given fresh consideration to the relationship of many tanagers to the other birds of the world. As a result, many of the North American tanagers are now closely allied with such birds as Northern cardinal and have been pushed into a tenuous relationship with tropical tanagers.

The scarlet tanager is not typically a feeder visitor, but you can lure these birds with 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 baltimore orioles and gray catbirds.

Fond of fruit, the scarlet tanager incorporates various berries into its diet. Landscape around your home with fruit-bearing trees such as mulberry, serviceberry and wild cherry to make your yard more inviting to these elusive bird.

Yes, the scarlet tanager is more often heard than seen, but it is a bird worth seeking out. A sighting is guaranteed to impress. Seeing a scarlet tanager will almost make observers feel like they’ve been dropped into a tropical jungle instead of standing beneath a woodland canopy in the Southern Appalachians.

I’ll be participating in some summer bird counts over the next few weeks, so I am hopeful that my 2022 drought of scarlet tanager sightings will soon be at an end.

Sales of local calendar fund bird-worthy aims

The front cover of the 2022 bird calendar produced by the Elizabethton Bird Club features a photo of a chestnut-sided warbler taken by club member Charles Warden. The calendar is available for purchase for $15, plus $2 for shipping and handling. They make great Christmas gifts for nature and bird enthusiasts. For more information, email ahoodedwarbler@aol.com. 

If you didn’t find all you needed on Black Friday for those on your shopping list, here’s a suggestion. The Lee and Lois Herndon Chapter of Tennessee Ornithological Society, also known as the Elizabethton Bird Club, has produced its annual calendar featuring bird photographs by its members and friends of the organization.

These calendars make wonderful Christmas gifts and stocking stuffers. This year’s front cover features a gorgeous photo of a chestnut-sided warbler taken by club member Charles Warden. This is Warden’s first year contributing photographs to the club’s yearly calendar project. More of his photos are on display through the calendar. He is a resident of Johnson City.

“I took the photo on the Spring Bird Count with Fred Alsop and Judi Sawyer on May 1 of this year at Hampton Creek Cove,” Warden said.

He said that the bird was among the blooms of what he thinks was an apple tree.

“We heard the warbler and chased it down,” he said. “It came out in the open and posed nicely for pictures.”

He has been interested in photography since he took a beginning photography class at East Tennessee State University on a lark in 1977.

“I am lucky enough to be making a living as a photographer for ETSU marketing.”

Bird photography is certainly a challenge, he said, and requires much patience, decent equipment and a lot of luck.

“It’s been a learning curve for sure, and it’s still a tough call when to take the binoculars down and put the camera up as it’s so mesmerizing to watch the birds,” Warden said.

The chestnut-sided warbler is a summer resident in the region and can be found at middle and higher elevations on many of the area’s mountains, including Unaka and Roan. Unlike many warblers, both males and females are brightly colored, with the female being slightly less so. Males during the summer nesting season show a yellow crown, black mask, white cheeks, throat and breast and the namesake chestnut flanking on his sides.

He’s also a cheery and persistent singer when he arrives on his nesting territory. His song is usually transcribed as “Pleased, pleased, pleased to meetcha!” For birders, it’s like a welcoming reintroduction each spring when this particular song is heard from the branches of trees in local woodlands.

For the singing male, there’s a more personal reason for singing his song. The “pleased, pleased, pleased to meetcha” refrain is a way of attracting the attention of potential mates. Males sing an entirely different song once settled into nesting activities with a mate. The song used to attract mates is more heavily accented, according to the website, All About Birds. Some males sing only unaccented songs and thus have a lower success rate at attracting mates.

Chestnut-sided warblers are classified by scientists as birds that favor successional habitats for nesting purposes. These sorts of habitats are usually disturbed by human activities such as logging. However, disturbed habitats can be created by natural occurrences, including fires, flooding and storm damage. During the winter months, this warbler withdraws into Central America with many individuals finding suitable habitat on shade-coffee plantations.

Female chestnut-sided warblers will weave a nest of bark, grass and other components all bound together with gathered spider silk. She will lay three to five eggs. These warblers make the most of the summer season, often nesting a second time after raising their first brood.

Chestnut-sided warblers feed largely on insects, but the birds also incorporate seeds and fruits into their diet. Young are fed by both parents on a diet of small insects, spiders and caterpillars. The chestnut-sided warbler’s scientific name, Setophaga pensylvanica, roughly translates as “eater of moths from Pennsylvania,” which is a nod to the bird’s insect-rich diet.

Other warblers that can be found in the mountains of Northeast Tennessee — and in the pages of the calendar — include black-throated blue warbler, golden-winged warbler, worm-eating warbler, hooded warbler, prairie warbler and common yellowthroat.

Like most small songbirds, the New World warblers, to which the chestnut-sided warbler belongs, don’t have long lifespans. A few individuals, however, defy the odds. According to the website, All About Birds, the longest-lived chestnut-sided warbler documented by scientists was a nearly seven-year-old bird banded in Rhode Island in 1980. The bird had been banded in the same state six years and 11 months earlier in 1973.

Of course, with the exception of the yellow-rumped warbler, most of the warblers don’t spend the winter months in the region. With one of these calendars, however, you can enjoy beautiful photos of some of our most lovely warblers while awaiting their return this spring in mid-April and early May.

The inside pages of the professionally-produced calendar feature dozens more full-color photographs and an informative and educational grid. These calendars sell for $15 plus $2 for shipping. All sales help the club fund birding programs, public park feeders, conservation efforts and other activities in upper Northeast Tennessee.

American crow’s dark reputation more from plumage than behavior

1 Reply

There’s something rather autumnal about watching a flock of American crows glean the last scattered kernels of corn from a harvested field as one of the flock stands sentry and ready to utter the alarm with some guttural “caws” should anything potentially threatening appear on the scene. Crows are such a part of the landscape that they would almost escape our notice if they didn’t come with centuries of accumulated baggage that makes us distrust them and suspect their every action.

While seeking birds far afield, I have occasionally spotted some innovative scarecrows standing guard in gardens and agricultural fields. I’m not sure if anyone still erects these human effigies for their original purpose of warding off crows and other feathered agricultural pests. These days, scarecrows likely serve an ornamental purpose and are often part of a yard’s whimsical Halloween or autumn decorations.

The crow, largely thanks to its glossy black feathers, but perhaps also with a nod to its avian intelligence, has long been associated with Halloween. Greeting cards and decorations for the holiday often feature depictions of bats, owls and black cats, as well as the inevitable crow and the accompanying scarecrow. With a brain about as big as a man’s thumb, the crow is renowned among ornithologists and other scientists for its keen intelligence. Crows are not fooled for a second by the charade of a straw-stuffed, brainless friend of Dorothy propped in a field.

Photo by Jack Bulmer/Pixabay • An American crow perches on a log. Due to its dark coloration, crows have often been associated with evil and other dark forces. In actuality, crows are admirable, highly intelligent birds.

The intelligence of this bird has long been known. Early American naturalist William Bartram wrote about a crow named Tom in a highly entertaining essay titled “Anecdotes of an American Crow.” Bartram, who lived from 1739 to 1823, brought humorous observations and keen insight to his subject as he wrote about the joys — as well as tribulations — of living with Tom, a crow that enjoyed tormenting Bartram’s dog and purloining the writer’s spectacles and trying to hide them.

The essay demonstrates that almost as soon as Europeans arrived in North America, some of those with a bent toward the natural world recognized the intelligence and amazing adaptability of the American crow. As well as writing about the natural world, Bartram earned widespread acclaim for his drawings of botanical and ornithological subjects. Tom, the featured crow in Bartram’s brief essay, certainly exhibited intelligence of an impressive degree. Not only did the crow steal his owner’s eyeglasses, he foiled Bartram’s first attempt to reclaim them. The story makes very humorous reading. To read Bartram’s account, visit http://www.geocities.ws/jswortham/crow.

What else have crows done down through the ages to gain such a dark and much undeserved reputation? It probably doesn’t help matters that a flock of crows is known as a “murder.” Ancient Greeks considered crows as omens, which often foretold death and other disasters. The warrior goddess known as the Morrighan from Celtic mythology often appears in the form of a crow or raven. She is also often portrayed as being accompanied by a group of these black-plumaged birds. Many Native American tribes revere crows as communicators between worlds. Crows have been documented using tools and solving problems, which shows an uncanny ability to analyze and strategize. The early Celtic people also noted and admired these traits in crows.

I think the Celts and Native tribes had the right idea. Crows are admirable birds for many reasons. For instance, they are very social birds, often forming family flocks. They may also form much larger flocks for the purpose of roosting. When nesting, this social behavior comes in useful for a mated pair. Offspring from previous successful nesting efforts often serve as helpers. In addition to gaining their own life experience on successful nesting and caring for chicks, these older siblings may protect the nest site from predators or even deliver food to fill hungry beaks and bellies.

While famous for their associations to humans and our agriculture, crows forage far beyond the cornfield for their food. Many crows scavenge road-killed wildlife, such as squirrels, opossums and rabbits. While they certainly don’t turn up their beaks at the notion of eating carrion, crows do so less often than birds such as turkey vultures, black vultures and the crow’s fellow corvid, the common raven.

The kinship to the raven is evident, but even moderately experienced birders rarely confuse these similar species. The raven is a large bird with a heavy beak, a distinctive profile and a wedge-shaped tail. In a direct comparison with a raven, a crow looks downright puny. Both are members of the corvid family, which consists of 120 species including jays, rooks, magpies and jackdaws. Some of the world’s other crows include the descriptively named little crow, hooded crow, carrion crow, collared crow, long-billed crow and violet crow. While most of the world’s crows are thriving, the Hawaiian crow has been extinct in the wild since 2002, although the species still exists in captive-breeding programs in various zoos.

Thanks to its resourcefulness and intelligence, the crow is deserving of more respect and even admiration. The American crow is a uniquely American success story. Think more of Bartram’s story about Tom the crow and not the dark, misguided myths and legends about crows this Halloween. Long may the crows fly.
