Bird of mystery, black rail famed for eluding birders

Photo by AGAMA/Adobe Stock • Adult male black rail (Laterallus jamaicensis) standing in a swamp during the night in Brazoria County, Texas. The black rail is a  secretive, rarely seen bird of wetlands and marshes. Much smaller than other members of the rail family, the bird doesn’t offer even determined birders any easy observations.

On Wednesday morning, Oct. 13, I fetched my mom’s newspaper before heading to work. Scanning the front page headlines while walking back from the mailbox, I missed a tiny bird.

The bird flushed into a panicked flight at the last possible second from right under my feet. At a glance, I knew at once that I’d seen something incredibly different. I can only describe the bird as a black, somewhat pear-shaped bird, perhaps a little larger than a typical sparrow, with a less than elegant flight that took it a couple of feet into a stand of cattails and other wet-loving vegetation.

Then, just like that, the bird was gone. After that brief encounter, which may have lasted at best a second or two, the bird vanished. With sparrows or warblers, an observer can squeak some notes to persuade a curious bird to come back into sight. I tried and got no response.

Of course, I didn’t think I’d seen a warbler or a sparrow. In an instant, perhaps one of the most significant bird sightings I’ve ever had at my home was concluded but hardly resolved.

I remained standing, staring, trying to determine what I’d just seen. I had an idea, but it was almost too unexpected and too unsupported to entertain. I won’t be adding it to my life list of birds seen, but I am fairly confident that I saw a black rail, one of the tiniest representatives in a family of birds that also include sora rail, Virginia rail, clapper rail and king rail.

When I describe the bird as tiny, it’s not an exaggeration. Adults are bigger than most sparrows but smaller than an American robin. They are gray-black birds speckled with white on the back. They have a black crown and chestnut patch evident on the back of the neck. The bill is black.The legs range from pink to wine-colored. The most striking feature of this bird, if observed under favorable conditions, is its bright red eyes.

Many birders have probably enjoyed a flight of fancy while imagining a beady pair of red eyes staring back at them from dense marsh vegetation. The black rail is so difficult to observe that it has become a sort of feathered “holy grail” for birders. I was certainly not expecting the possibility of my path crossing with this tiny wanderer.

The black rail has not been extensively studied by scientists, which means much about this elusive bird of marshes and wetland is poorly understood. There are different reasons behind the mysteries surrounding the bird.

For instance, although it does vocalize, black rails call mostly after dark. Not many people go wandering through marshes at night, so black rails largely go unheard.

In addition, when these small birds perceive a threat, they prefer running through dense vegetation instead of taking flight. Some black rails in northern areas are migratory, so these birds are capable of sustained flight. They simply don’t like to fly unless circumstances dictate flight upon them. They’d prefer to scurry through wetland, much like a small rodent. They are even known to take advantage of trails blazoned through marshes by mice and other small rodents.

A few aspects of my observation work in favor of the bird being a black rail. I’ve seen other rails — sora, Virginia rail and clapper rail — on multiple occasions. Virginia rail and clapper rail can be ruled out. They’re too large and too different in appearance to be mistaken for a black rail. The sora bears a certain similarity to a black rail, but it is mostly brown and gray with a yellow bill. It’s also larger than a black rail.

Once the black rail’s close kin are eliminated, there aren’t any other likely suspects that might be confused with it. It’s frustrating. I will likely always refer to this sighing as “the bird that looked a lot like a black rail.” My hesitation stems partly from the simple fact that so many birders are unable to ever get a look at this bird. Why should I have had better luck, even if only for a split second?

Incidentally, two of my best rail sighings have taken place in Erwin.

Back in 2000, I observed a Virginia rail stepping delicately and deliberately though some cattails and other vegetation on the fringes of the wetland area adjacent to the large pond at Erwin Fishery Park. I watched the bird move carefully and deliberately through the vegetation. It was only for a moment or two, but it was of longer duration than my recent “blink-and-you-missed-it” observation of the black rail in my driveway.

My best observation of a sora took place in the spring a few years ago during a visit to the boardwalk over the wetlands near the industrial park in Erwin. The boardwalk is part of the extended linear trail in town. I was birding that day with Margaret Roy, the former manager of Mountain Inn & Suites of Erwin.

Margaret wanted to learn more about birds, and we really got lucky when we found such an uncommon bird only minutes after we stepped onto the boardwalk. It was as simple as looking down on the mudflats and noticing an odd, plump bird walking without concern beneath us. From our elevated viewing platform, we got excellent looks through binoculars and I took some photos.

Early naturalists, even without benefit of binoculars, were aware of the black rail. John James Audubon, the famous painter and naturalist, painted a black rail and its chick. Audubon referred to the elusive denizen of wetlands depicted in his painting as the “least water-rail.” Others have called the bird by such names as “least water-hen,” “little black rail” and “black crake.” In some parts of the world, rails are referred to as crakes, but they are basically all the same type of bird.

According to the website, All About Birds, black rails have been eliminated from many saltwater tidal habitats. The website even encourages people to listen for black rails in spring in freshwater wetlands. Although they favor tidal habitats on the coast, black rails will nest in a variety of wet meadows, marshy edges, and even along creeks and rivers. Some event attempt to nest around farm ponds or fields of hay with standing water.

Black rails are scarce, but they do range throughout the United States and Canada. The two states with the most black rails are Florida and California. Unfortunately, those two states feature habitats under siege from human encroachment.

Because of their small size, black rails are limited water that is more shallow than used by most rails. They feed on seeds, insects, crustaceans and mollusks. In 2015, the black rail was confirmed as a nesting species in South Carolina after long being classified as a non-breeding migrant to the state.

High tides that force these birds from their dense cover make them vulnerable to predators ranging from herons and hawks to foxes and cats.

Rails belong to the family of birds known as Rallidae, which includes not only crakes and rails, but coots and gallinules, too. The entire family consists of about 150 species, including bird with such descriptive names as grey-throated rail, ash-throated crake, snoring rail, invisible rail, chestnut rail and striped crake. Many species of rails, particularly those that evolved on isolated islands, have become flightless.

There’s a saying that lightning never strikes twice. I’m hoping the saying is wrong. I’ve learned a lot about this fascinating bird while researching the topic of black rails after my all-too-brief sighting. I’d very much like to get a more satisfying look at a black rail some day.

Fingers crossed.

 

Christmas Bird Count makes for fun outing during the holiday season

carolinawren-snow

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

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

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

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

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

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

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

Red-shoulderHawk

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

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

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

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

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

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

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

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

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

Hawk spoils start of winter bird feeding season

According to a recent Census Report, Americans are feeding birds in epic numbers — 63 million people in this country make life less of a struggle for birds by filling bird feeders with sunflower seeds, peanuts and other goodies. In fact, watching and feeding birds ranks second only to gardening as one of America’s popular pastimes.

Unfortunately, bringing wild birds into our lives means we are occasional witnesses to the darker side of nature that dictates there’s a survival of the fittest competition taking place in our own backyards and gardens.

sharp-shinned-hawk-dbadry

Photo by Dbadry/Pixabay.com • A sharp-shinned hawk visits a bird bath during the Christmas season. These small hawks, designed to prey on songbirds, sometimes learn to stalk feeders, which creates distress for the human landlords.

Welcoming birds into our yards and lives means inviting all birds, include predatory raptors such as sharp-shinned hawk, merlin, Cooper’s hawk and American kestrel. It’s a problem Elizabeth Laing has had to cope with in recent weeks. We’ve commiserated over Facebook about her conflicted feelings about the predatory nature of the hawk that’s been stalking birds at her feeders.

Elizabeth sent me a message via Facebook on Nov. 21 about a situation unfolding at her home in Abingdon, Virginia.

“Please help me to know what to do,” she wrote as the start of her message. “Right now I an absolutely devastated and in tears. I have about eight feeders up year round. I feed a lot of small birds in my backyard and even crows in my front yard. I have at least 15 American goldfinches right now at several sunflower chip feeders.”

Elizabeth noted that for the past few days she had seen a small hawk in her backyard for the first time ever.

“I was worried and tried to scare it off,” she wrote. “I realize they have to eat, too, and are beautiful birds, but I don’t want them killing birds on my feeders.”

1-sharp-shinned-hawk-john-james-audubon

John James Audubon painted this pair of sharp-shinned hawk and shows the size difference between males and females. Many people are surprised to learn that female hawks are typically much larger than males, which is also true of the Cooper’s hawk.

Unfortunately, that’s what happened right as she watched through a window as a goldfinch feeding at her feeder.

“The hawk swooped in and grabbed him off the feeder,” she reported.In the wake of the hawk’s action, Elizabeth took some sensible steps, including immediately taking down her feeders.

Some of her birds, such as the tufted titmice, came back quickly and perched on the empty feeder poles. “I felt so bad,” she said. “I want to feed them, but I can’t stand the thought of them being snatched off my feeders.”

She concluded her message by asking my advice. I responded and told her that when hawks do make a habit of raiding feeders, it can be necessary to curtail feeding for a couple of weeks or longer. Most authorities on birding insist that the hawks will lose interest and move to more productive feeding grounds. Unfortunately, the raptor visiting Elizabeth’s yard proved persistent.

Photo by NatureLady/Pixabay.com Immature sharp-shinned hawk look different than adults, but once they learn to hunt, they are very efficient predators.

 

“I wanted to update you on my hawk problem,” Elizabeth wrote back in another message on Nov. 26. “I took all my feeders down, but not long enough. After five days, I put them back.

She had also invested in brand new, expensive caged feeders. She purchased the caged feeders thinking the goldfinches would be safe inside.

For flocking birds, like American goldfinches, the caged feeders offered security only to birds inside the caging. Those birds waiting outside of the caging for their own turns at the feeder remained vulnerable.

“I found feathers on the side of one cage this morning,” she wrote. “Then, as I was watching a bunch eat, that hawk swooped in and took another one off the side.”

The entire situation has made her discouraged and sad. “I hope this doesn’t mean I will have to stop feeding birds entirely. I actually have bags of seeds and peanuts (for the titmice) coming in the mail later this week,” she wrote.

In the wake of the latest attacks, she has taken down the feeders again. “I will leave them down for two weeks this time,” she wrote. “I know the hawk has to eat, too, and it’s a beautiful bird, but I can’t do this to my little goldfinches.”

I agreed that it would be senseless, as well as rather cruel, to provide food for songbirds while knowing a hawk is lurking in the vicinity.

FirstHawk

Elizabeth also asked if I have had birds killed at my feeders. Although it has been a thankfully rare occurrence, hawks have snatched birds visiting my feeders. I’ve not often witnessed the actual predation, often finding only a pile of feathers on the ground as evidence of the hawk’s success.

A few years ago, however, I witnessed a rather dramatic attack on New Year’s Day. As I watched a female Northern cardinal feeding on sunflower seeds spilled onto the ground by the birds visiting a hanging feeder, a sharp-shinned hawk suddenly slammed into the cardinal. In an instant, I saw my first and second bird species of the New Year. The cardinal, however, didn’t get to live and enjoy the unfolding year.

The website allaboutbirds.org described the sharp-shinned hawk as “a tiny hawk that appears in a blur of motion — and often disappears in a flurry of feathers.” It’s an apt description of this pint-sized predatory bird.

The website also notes that studies indicate that feeders don’t make it more likely that our favorite songbirds will be preyed upon by a sharp-shinned hawk or other raptor. Although feeders might temporarily attract a raptor, these birds will catch the majority of their prey elsewhere.

The sharp-shinned hawk belongs to a genus of raptors known as accipiters, which are slender raptors with rounded wings and long tails. They are highly maneuverable in flight. A characteristic of accipiters is long legs and sharp talons. In fact, the genus is named from the Latin word for hawk, “accipere,” which can be translated as, “to grasp.”

Photo by Sarangib/Pixabay.com • A shikra (Accipiter badius) is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk.

Other members of the accipiters in North America include the Cooper’s hawk and Northern goshawk. Other accipiters around the world include such raptors as chestnut goshawk, red-chested goshawk, crested goshawk, little sparrowhawk, spot-tailed sparrowhawk, black sparrowhawk and red-thighed sparrowhawk.

Elizabeth sent me one other message, informing me that she had also advised her neighbor to take down his feeder, which he did. Shortly after he did so, Elizabeth saw the hawk attack a squirrel, which, thanks to Elizabeth rapping on a windowpane, apparently survived the attack.

coopers-hawk-570341_1920

Photo by Skeeze/Pixabay.com The Cooper’s hawk, like this individual, is a larger relative of the sharp-shinned hawk. It’s larger size allows this raptor to prey on larger birds, such as mourning doves.

In addition, if the hawk in her yard is attacking squirrels, her visitor is probably a Cooper’s hawk, a bird almost identical to a sharp-shinned hawk except for its larger size. I’m hopeful that an extended hiatus will convince the hawk to leave Elizabeth and her goldfinches in peace.

It’s still good to remember that hawks view smaller birds flocking to a feeder in the same way those small songbirds view the abundance of seeds. For both hawks and songbirds, our offerings represent easy meals. It’s not easy, but the best choice is to co-exist — if not at peace, then at terms with nature’s reality.

Family of pigeons, doves features one famous member

Vivian Tester of Bristol, Tennessee, sent me an email seeking help with a pigeon problem.

“I need your advice on trying to keep the pigeons off my bird feeders,” Vivian wrote. “They are chasing off the birds I want to feed and devouring all the seed. My neighbor says they are doves but whatever they are, they are annoying. I don’t know if the squirrel-proof feeder would work or not. I would appreciate any help.”

I recommended that Vivian offer only black oil sunflower seeds to see if that might can discourage the unwanted guests. While pigeons will eat sunflower seeds, they much prefer smaller seeds like milo and millet often found in mixed seed packages. If their preferred food source dries up, they may be convinced to move elsewhere.

Stopping feeding for a trial period is another possibility. Remove food for a week and then slowly start offering seeds again. If the pigeons have moved to other feeding grounds, perhaps they will be slow to return.

It’s a tough problem to solve. Although some feeders can be designed to prevent a large bird like a pigeon or dove from perching, the birds are going to still make the attempt. In doing so, they knock seed to the ground below and will happily feed on the spillage. The best option for avoiding pigeons would be to use tube feeders designed for minimal spillage if jostled. Doves and pigeons prefer to feed on the ground, so scattering seeds there, intentionally or inadvertently, is an invitation for flocks to gather.

PIGEON-PIC

Photo by Jean Potter • The widespread rock pigeon is one of the most successful members of the bird family Columbidae, which is comprised of some 310 species of doves and pigeons. One of the most famous representatives of the family is the dodo, an extinct relative of such common birds as the mourning dove and rock pigeon.

Nature, too, offers a solution. Several species of raptors prey readily on doves and pigeons. Peregrine falcons and Cooper’s hawks are two effective controls on such birds, but it is not easy to issue an invitation for one of these birds to take up residence in your yard.

The two mostly likely offenders in the region are the mourning dove and the rock pigeon. Mourning doves are an abundant native species at home in both rural areas and suburbs. The rock pigeon is not a native species but has thrived in the United States since it first arrived with early colonists from Europe. Rock pigeons are mostly a problem for people attempting to feed birds in urban and suburban areas.

Pigeons and doves constitute the animal family Columbidae, which is comprised of some 310 species. One of the most famous members of this family is the extinct bird known as the dodo. The well-known story of the dodo doesn’t often make reference to the relations this bird had to living doves and pigeons.

Roelant_Savery_-_Landscape_with_Birds_-_WGA20885 2

In the lower right corner of this illustration, a dodo is visible along with such birds                        as macaws, cranes, and even a wild turkey. Titled “Landscape with Birds,” this painting            was done by artist Roelant Savery in 1628.

Early scientists did not know what to make of the dodo and theorized that the unusual flightless bird was everything from a small ostrich to flightless versions of an albatross or a vulture. Johannes Theodor Reinhardt, a zoologist from Denmark, hinted at the dodo’s relationship to the world’s pigeons and doves as early as 1842. At first his theory was ridiculed, but other biologists and zoologists eventually came to accept the fact that the dodo was indeed a large, flightless pigeon.

The dodo stood a few inches over three feet tall and could weigh close to 40 pounds. Most of what is known about the dodo comes from paintings and drawings of the bird made by early explorers in the 17th century. Some of the humans who observed the bird also left behind valuable written accounts. First discovered by Dutch sailors who visited the Indian Ocean island of Mauritius in 1598, the dodo became extinct only 64 years later. So about the same time the rock pigeon was establishing itself as an introduced species of bird in North America, around the world one of its cousins slid quietly into extinction.800px-Van_den_Venne_dodo 2

The dodo has acquired a reputation in popular culture as slow-witted, lethargic, fat, clumsy and stupid, dooming the bird as a creature too ill-suited to exist. Today, most scientists believe that the dodo was adapted perfectly to its island habitat. Having evolved as a flightless bird, the arrival of humans in its paradise meant its doom. The reputation for stupidity is unfair. Having never encountered humans, dodos did not have an instinctive fear of them. This lack of fear made it easy for the early explorers of their island home to quickly render them extinct.

Modern science has even pinpointed the dodo’s closest living relative. Thanks to DNA analysis, the Nicobar pigeon of southeast Asia has been identified as the closest relation of the dodo. The Nicobar pigeon is much smaller (only 16 inches long) and, unlike its famous relative, is capable of flight. This pigeon feeds mostly on fruit and seed. When grain of any kind is available, it will also make use of such a food source.

Most contemporary sources reveal that the dodo enjoyed a diet rich in fruit, but modern biologists speculate the dodo probably also foraged for nuts, seeds and tubers. It’s ironic that the dodos were slaughtered to extinction to provide food for early explorers of their island. An English explorer by the name of Sir Thomas Herbert recognized the dodo’s exploitation as a food source, but disparaged the bird’s taste. “To the delicate they are offensive and of no nourishment,” Herbert wrote in his published work, “A Relation of Some Years Travel into Africa and the Greater Asia.”

Lophopsittacus.mauritianus

This sketch, completed in 1634 by Sir Thomas Herbert, shows a broad-billed parrot, a red rail and possibly one of the last dodos to exist on the planet. Herbert described the dodo as a rather poor food source for early explorers to its island home. 

Like the pigeons that have become a scourge on Vivian’s feeders, it’s very likely that, had they survived, dodos might visit feeders today on the island of Mauritius. For the most part, the world’s doves and pigeons are considered successful birds.

In the United States, some other native doves include the widespread mourning dove, as well as white-winged dove, common ground dove and Inca dove. The Eurasian collared-dove, introduced into the Bahamas and Florida, has now spread extensively into the United States and is known to have established populations through northeast Tennessee and southwest Virginia.

Dove-Wing

Some descriptive names for some of the world’s doves include purple-winged ground dove, lemon dove, zebra dove, ochre-bellied dove, tambourine dove, white-faced cuckoo-dove, ring-necked dove, little cuckoo-dove and sapphire quail-dove. Pigeons have also been bestowed with such colorful names as snow pigeon, speckled pigeon, yellow-eyed pigeon, pale-capped pigeon, metallic pigeon, crested pigeon, pink pigeon and squatter pigeon.

We all like to attract as many birds as possible to our yards and gardens. A variety of food will help achieve that objective. Be aware, though, that such free buffets will also encourage messy birds like pigeons that make feathered pigs of themselves and almost always overstay their welcome. There’s also the option to admire pigeons and doves as survivors with a lineage worthy of some admiration. Hang some tube feeders accessible to smaller songbirds but toss some seeds into a corner of the yard for the ground-feeding pigeons and doves. They’re birds, too, after all.

Sora observation spring surprise as pace of migration increases

The hummingbirds, as I reported last week, are back. I’m hearing from readers across the region about the arrival of these tiny flying gems.

• Nata Jackson, who lives in Greene County, sent me an email to let me know that she saw her first Ruby-throated Hummingbird of spring on April 14. She had put up her feeders at about 2 p.m. Five hours later, she walked by the window and saw a male hummingbird at one of the feeders.

• April Kerns Fain of Erwin reported on Facebook that her hummingbirds returned on April 16, which was a very chilly day. “My hummingbirds are back and I had to thaw their sugar water for them,” she wrote. “Yuk!”

• Patricia Faye Wagers, who lives in Kingsport, saw her first hummingbird — a male — of spring on April 16, as well.

However, after I saw my first hummingbird of spring on Friday, April 11, I haven’t seen one since. Maybe the cold snap persuaded them to keep journeying north, or maybe they turned back south for a few days. I’m hopeful a few hummingbirds, as they usually do, will take up residence in the yard for the rest of the summer.

I spent the morning of Friday, April 11, birding with Margaret Roy along the linear walking trail in Erwin. She wanted to get an introduction to a guided birding experience in advance of a planned fall birding tour that we plan to offer through Mountain Inn & Suites of Erwin, where Margaret is the general manager.

We had a fantastic morning, highlighted by a lengthy observation of a Sora from the wetland boardwalk near the industrial park. The Sora is a member of the rail family, which includes such species as Clapper Rail, Virginia Rail, King Rail, Yellow Rail and Black Rail.

We also saw a Greater Yellowlegs, Solitary Sandpiper, Yellow Warbler, Yellow-rumped Warbler, American Coots, Pied-billed Grebes, Brown Thrasher, Song Sparrows, Mallards, Canada Geese, Blue-gray Gnatcatchers, Northern Rough-winged Swallows, American Robins, Downy Woodpeckers and a pair of Red-bellied Woodpeckers excavating a nesting cavity in a sycamore tree.

Several of the birds – Greater Yellowlegs, Solitary Sandpiper and Yellow Warbler represented my first spring sightings.

Our observation of the Sora, however, provided the most excitement of the morning. This is a bird that is only infrequently encountered, especially in this region. Rails, the Sora included, are shy, elusive and designed with the primary purpose of avoiding notice.

Worldwide, there are more than 130 species of rails. Many members of the family are called rails or crakes, but the family Rallidae also includes coots, moorhens, swamp-hens and gallinules.

Many species of rails have evolved into flightless species of birds. All the species encountered in North America, however, are capable of flight and long-distance migrations. Many of the world’s flightless rails have gone extinct in the past few centuries. Many are considered endangered, including Lord Howe Woodhen, the Takahē and the Guam Rail.

The Sora is a small bird that’s not much bigger than an American Robin. While many rails are plain-looking birds, the Sora is fairly distinctive in its appearance with a slaty gray body, a short, yellow bill, long legs and a short tail, often held upright showing white underneath. Soras also have a black face and throat.

As we watched the Sora foraging among cattails and other vegetation beneath the boardwalk spanning the wetland along the linear trail, the bird moved deliberately and alertly. As we watched, the Sora flipped over leaves and other debris with its bill, often snatching small prey organisms. This bird enjoys a varied diet that can include seeds, insects, crustaceans and snails.

At the end of our observation, the Sora turned and simply walked into the cattails, fading from view almost instantly. The sudden disappearance of a bird so capable of navigating effortlessly between reeds and cattails reminded me of the phrase, “as thin as a rail,” which seems particularly apt for the Sora.

This normally secretive bird makes its home in freshwater marshes throughout Canada and the central United States. The Sora is the most common and widely distributed rail in North America. The Sora also ranges into Central and South America. Like many rails, it is quite vocal with a distinctive descending whinny call can be easily heard from marsh vegetation, but actually seeing a Sora is often a fluke of being in the right place at the right time.

The sighting recently in Erwin is the best I’ve ever had of a Sora in Northeast Tennessee. Another memorable observation of a Sora took place years ago on Fripp Island, S.C., when my mother and I watched a bird wading at the edge of a waterway on one of the island’s many golf courses.

In addition, during a field trip many years ago with members of the Lee and Lois Herndon Chapter of Tennessee Ornithological Society, I saw a Sora wading in a flooded ditch in a pasture at Austin Springs on Boone Lake.

Many of my encounters with this species have been represented only by hearing them call from wetlands in Bowmantown and Shady Valley.

The book, “The Birds of Northeast Tennessee” by Rick Knight, classifies the Sora as a transient bird in the region that is occasional to uncommon in spring and fall.

Two days after Margaret and I saw the Sora in Erwin, Elizabethton residents Cathy Myers and Tom McNeil found a Sora and a Common Yellowthroat at Henderson Marsh, which is located in on Crestview Road in Bowmantown in Washington County.

Of course, Soras are only one of many species migrating through the region. Vireos, warblers, shorebirds and flycatchers are among those arriving with every passing day.

Many birds are already nesting. A female Northern Cardinal is sitting on a nest in a yew tree at my home on Simerly Creek Road in Hampton.

I also visited the Great Blue Heron nesting colony along Blevins Road on the Watauga River in Elizabethton. I found several more nests have been added since my last visit a couple of weeks ago.
