Hummingbirds, other summer birds get ready to depart

Photo by Bryan Stevens • A ruby-throated hummingbird visits a feeder for a sip of sugar water.

I always feel some reluctance and regret when I turn the calendar page from August to September.

I don’t have anything against fall – it’s my favorite season. But I know that our ruby-throated hummingbirds, which returned only five months ago in early April, will soon be departing.

It won’t be only the hummingbirds. Warblers, orioles, tanagers and other migrants will also fly south to spend the winter season somewhere more hospitable.

Most of the hummingbirds that visited our gardens over the summer are getting ready to migrate back to their winter homes in Central America.

I’m seeing only a few adult male hummingbirds with the namesake red throat. They are outnumbered by females and young hummingbirds that hatched in late spring and throughout the summer. It’s fun to watch young hummingbirds. They often have something to prove. In many ways, they’re even more feisty than adult birds.

In any given year, the numbers of hummingbirds passing thorough is going to fluctuate. Some years, these tiny flying gems will be present in good numbers on an almost daily basis. Other years, hummingbirds can become quite scarce.

I usually enjoy my best hummingbird numbers in the fall as these little birds begin their leisurely journey back south. Late August and the month of September is usually a great time to watch hummingbirds.

During August, the feeders at my home and my mother’s home saw a great deal of activity. Blooms of wildflowers and cultivated flowers also attracted them. Earlier in the summer the hummingbirds went gaga for the crocosmia blooms and the flowering bee balm. For the past month, the tube-shaped flowers of orange jewelweed has kept them coming back for more.

The New World is home to about 360 species of hummingbirds. We’ve expended many adjectives in finding names of them all. Sometimes, words fail. Mere adjectives are somewhat inadequate in providing common names for many of the world’s more hummingbirds, but that doesn’t keep us from trying to give descriptive names to each hummingbird species. For instance, we have the beautiful hummingbird of Mexico; the charming hummingbird of Costa Rica and Panama; the festive coquette of northwestern South America; and the magnificent hummingbird of the southwestern United States.

Other names are even more elaborate and occasionally outlandish, such as the white-tufted sunbeam of Peru; the violet-throated metaltail of Ecuador; the violet-throated starfrontlet of Peru and Bolivia; the hyacinth visorbearer of Brazil; and the rainbow-bearded thornbill of Colombia and Ecuador.

As for our own ruby-throated hummingbirds, wish them well as they begin that long trek back to their wintering grounds. For the young birds, this will be their first epic crossing of the Gulf of Mexico, something the species must do twice a year to get to and from their summer home in eastern North America.

Diminutive green heron flies beneath the radar but is not uncommon

Photo by Bryan Stevens • A green heron captures a tadpole at a pond’s edge.

Retrieving the mail from my mailbox requires a slight trek, but there’s always something to see in the few minutes it takes to complete this task six out of seven days every week.

On a recent stroll to fetch the mail I startled a green heron from the vegetation surrounding the fish pond. The heron made a startled cry and flew to a horizontal branch in a tree adjacent to the pond.

It’s been so long since I’ve seen this small wading bird up close that I’d forgotten its diminutive nature. Although the official name is green heron, I’ve almost always referred to this species as “little green heron” or simply “little green.” It’s not completely uncalled for. After all, there’s a little blue heron. As far as my research tells me, however, there is no great green heron.

Photo by Bryan Stevens • Upcoming programs in the region will focus on topics such as songbirds, raptors and the basics of beginning birdwatching. Plan to attend one or more of the programs to learn more about birds, such as this green heron.

Green herons are not restricted to coastal areas, but it was still somewhat unexpected. I’m hoping I didn’t frighten the bird too badly and it will continue to haunt the edges of the fish pond. The vegetation around the pond makes it easy for this heron to conceal itself. The pond is also a great place for the heron to forage. There’s an abundance of some of its favorite prey, including tadpoles and dragonflies.

Green herons and other wading birds are usually quite abundant in wetlands across the country in late summer. The scientific name — Butorides virescens – of this bird comes from a mix of Middle English and Ancient Greek and roughly translates as “greenish bittern.”

There are only two other species in the genus Butorides — the lava heron, which occurs on some of the Galapagos Islands of Ecuador, and the striated heron, which is found in wetlands throughout the Old World tropics from West Africa to Japan and Australia. This heron, which is also known as the mangrove heron, also occurs in South America.

The green in the bird’s plumage appears as a dark green cap, as well as a greenish back and wings. Adult birds also have chestnut-colored neck feathers and a line of white feathers along the throat and belly. These herons often assume a hunched position, making them look smaller than they actually are.

It’s been a good summer for wading birds. In addition to the green heron, a great blue heron has been lurking in the creekand at the fish pond. Much larger than the green heron, it’s not as easy for the great blue heron to escape notice.

Other locations to look for both these herons are at the pond at Erwin Fishery Park. You’ll also want to keep alert when walking along the linear trail in Erwin. This is the time of year when interesting herons or egrets are not all that scarce.

Farm ponds in the countryside around Jonesborough, as well as wetland habitat around the town’s Persimmon Ridge Park, are also good places to look for green herons. The wetlands at Sugar Hollow Park in Bristol, Virginia, is another dependable location for seeing this small heron. Most green herons will depart in late September and early October. This small heron retreats from the United States during the winter season but returns each spring in April and May.

Photo by Bryan Stevens • A green heron finesses a captured tadpole in its bill.

The green heron’s range during the nesting season includes Canada and much of the United States. Green herons will sometimes form loose nesting colonies, but at other times a pair will choose a secluded location as a nest site. The female will usually lay from three to five eggs. Snakes, raccoons and other birds such as crows and grackles are potential threats to eggs.

For the most part, the population migrates to Central and South America for the winter months. A few herons — great blue heron and black-crowned night heron — remain in the region throughout the year, even enduring the cold winter months in Northeast Tennessee, Southwest Virginia and Western North Carolina.

Green herons are probably more common than we realize. They are skilled at blending with their surroundings, but sharp eyes can find these herons around almost any body of water, whether it is pond, marsh, river, creek or lake.

Keep looking for green herons and their larger kin for the next few months. To share a sighting, ask a question or make a comment, send me an email at ahoodedwarbler@aol.com.

Birds boast phenomenal knack for long-distance travel

Hans Toom/Pixabay • The blackpoll warbler has one of the more difficult and lengthy migrations of the family of warblers.

The phenomenon of migration isn’t exclusive to the neotropical migrants of the New World. Birds in other parts of the world migrate, too. Waterfowl, shorebirds and raptors are among some of the families of birds that stage impressive migrations.

Of course, I spent most of my birding within Tennessee, particularly in the Northeast Tennessee region. Since the Volunteer State has no access to the sea, it is sometimes amazing how many birds affiliated with coastal areas can be found if you know when and where to look. Fall’s a good time to scan lakeshores, river banks and the edges of farm ponds for migrating shorebirds and wading birds.

I discussed last week some of the species I hope to see this fall. Every time I see some of these migrants I am impressed by what a phenomenal feat each and every single one of these birds represents. As my mother is fond of asking: “How do they do it?”

For such relatively small creatures, many if our birds are world-class travelers. Here are a few profiles of some of these incredible migrants.

One good tern deserves another

The Arctic tern, for example, truly takes migration to extremes. This small seabird travels each year from its Arctic nesting grounds to the Antarctic region, where it spends the winter months. Put into terms of mileage, the Arctic tern can travel about 50,000 miles in a single year. For a bird with a body length of about 15 inches and a wingspan of about 28 inches, this incredible migration is an astonishing feat. These statistics permit the Arctic tern to easily lay claim to the title of champion migrant among our feathered friends. According to the website for National Geographic, Arctic terns face a serious threat from climate change. In a profile on the tern at its website, National Geographic warns that Arctic terns are projected to lose 20 to 50 percent of their habitat due to the temperature changes linked to climate change. They also face loss of habitat due to encroachment by human activities such as oil drilling.

Photo by Bryan Stevens • Despite a perceived disadvantage of size, ruby-throated hummingbirds are quite capable of thriving in a giant world.

Size matters less than we think

The ruby-throated hummingbird makes an impressive migration each year. It’s even more awesome when one considers the diminutive size of these small travelers. Just to reach the United States, these tiny birds undertake a strenuous journey. They leave their wintering grounds in Central America to return to the United States and Canada for the nesting season. Most of these tiny birds, which are barely four inches long, make a non-stop flight of more than 500 miles across the Gulf of Mexico. The journey can take almost an entire day. With the end of summer, the entire population of ruby-throated hummingbirds, increased by a new generation of young birds, makes the Gulf crossing for a second time in a year to return to the American tropics for the winter months.

Photo by U.S. Fish & Wildlife Service/Steve Maslowski The bar-tailed godwit stages migrations that can take nine days of non-stop flight spanning nearly 6,000 miles.

 

Godwits, by Jove!

Shorebirds, which in North America can consist of birds ranging from turnstones and sandpipers to willets and avocets, are champion migrants. For instance, the bar-tailed godwit makes an impressive non-stop migratory flight. This shorebird nests in the United States only in parts of remote Alaska, but this godwit also ranges into Scandinavia and northern Asia. Some of these godwits make a nine-day, non-stop migratory flight that takes them from New Zealand to the Yellow Sea of China and beyond, a distance of almost 6,000 miles each way. Needless to say, since the godwits make no stops along the way, they must also go without food for the duration of their journey. The female godwit is larger than the male, but she still weighs only 12 ounces. The long-billed, long-legged bird is about 17 inches in length from the tip of the bill to its tail. That a creature so small can make such a distant, arduous trip and be the none the worse for wear is truly inspiring.

A fine kettle of hawks

Many North American raptors migrate, but the broad-winged hawk dislikes the lonely aspects of solitary travel. Instead, these hawks form large flocks, known as kettles, during migration. In autumn the majority of these raptors travel past human-staffed hawk migration observation points, which are dubbed “hawk watches,” during a brief and concentrated period of only a few weeks. Observing the phenomenon locally is possible at the Mendota Fire Tower Hawk Watch site atop Clinch Mountain at an abandoned fire tower near Mendota, Virginia. Broad-winged hawks are part of the family Accipitridae, which includes 224 species of hawks, eagles, vultures and other birds of prey. Broad-winged hawks are truly long-distance migrants. Many hawks passing over Mendota may end their migration as far south as Brazil. These hawks travel in flocks that can consist of hundreds or thousands of individuals. The birds conserve energy by soaring on thermals and mountain updrafts.

Jean Potter • Warblers, such as this male black-throated blue warbler, migrate into North America each spring to nest and retreat each fall for conditions farther south during the winter.

Traveling in stages

Most of the warblers that nest in North America retreat to Central and South America during the winter months. Few warblers, however, make as great a journey as the blackpoll warbler. Instead of migrating over land, this five-inch-long warbler undertakes a two-stage migration. The first half of the migration is a non-stop flight of about 1,500 miles. Every fall, these tiny birds fly over the ocean during this part of their migration, departing from Canada or the northern United States and not stopping until they reach various locations in the Caribbean. There they will spend some time recovering from the exhausting first half of their journey before they continue their way to such South American countries as Colombia and Venezuela.

Looking for fall migrating birds already underway

A male Wilson’s warbler perches in some branches. Many species of warbler migrate through the region each fall.

Summer’s waning. Just look at the calendar. We’re already approaching the midway point in August.

Birders track the transitions as one season merges into another, knowing that these are some of the best times to seek out birds. Fall migration doesn’t wait for a page to turn on a calendar. In fact, some birds are already on the move. I thought I’d devote this week’s column to some of the birds I hope to observe this fall as a mass migration draws many of our summer residents south toward warmer wintering grounds. In no particular order, here are some of the birds I’m hoping to see this autumn.

COMMON NIGHTHAWKS

The name common nighthawk is a misnomer. The species is not strictly nocturnal and it is certainly not a hawk. It’s actually a member of the nightjar family, which includes such birds as chuck-will’s-widow and whip-poor-will. The nighthawk doesn’t offer a serenade like these relatives, but it does produce a “pent” call that sounds much like an electric buzzer. It’s often the first indication of one of these birds swooping overhead. Nighthawks form impressive flocks, often numbering in the dozens or even hundreds. They are often active in evening hours, but I’ve seen large flocks of these migrating birds in mid-afternoon. August and September are the best time to look skyward to enjoy the spectacle of a large flock of swooping nighthawks as they pass overhead.

I didn’t host any of these colorful birds this spring, so I hope to get another opportunity this fall. The males in their vibrant black-and-white plumage and namesake breast patch of rosy-red feathers are slightly less colorful in the fall. I’ve actually had better luck in autumn hosting these birds at feeders. They love sunflower seeds, so keep your feeders stocked with their favorite foods to increase your chances. Females and young birds look different than adult males, but the heavy beak (the word “gros” is German for large) is a good indicator of their identity. Bird banders netting this species to document information for science can testify that these birds are also capable of a nasty nip at careless fingers with that stout bill.

WARBLERS

These birds are undeniably at their most gorgeous during spring migration, but many species of warbler retain colorful plumage into the fall season. Young birds, often in a plumage entirely different than adult birds, are responsible for the term “confusing fall warblers.” I’ll be looking for the species that are harder to locate in the spring, including bay-breasted warbler, Cape May warbler, Blackburnian warbler and Tennessee warbler. I’ll also be hoping for a rarity such as cerulean warbler or mourning warbler. I will be sad when the parade of warblers produces a palm warbler or a yellow-romped warbler. These last two species are a sure sign that fall migration’s coming to a close for another season.

WADING BIRDS

Late summer and early fall can also be a fantastic time for scanning rivers, lakes and farm ponds for wading birds. Hurricanes in recent years have even forcibly relocated American flamingos to Tennessee and other unlikely locations. It’s slightly more reasonable to hope for something unexpected like a wood stork or roseate spoonbill. The more likely candidates for observing in the region are great egrets, tri-colored herons and snowy egrets. It’s also a last chance to view green herons before this small species retreats to warmer locations for the coming winter.

Bryan Stevens • A hermit thrush perches on a fence.

THRUSHES

These medium-sized songbirds are typically brown in plumage, often with spotted white breasts. They’re beautiful singers in spring and summer, but they’ve often cut back on their singing by fall. Nevertheless, they form large migrating flocks that will roam autumn woodlands to rest and refuel during short breaks from migrating. Swainson’s thrush is not difficult to find in the fall. This species is named in honor of 19th century artist and ornithologist William Swainson. Like most birders, I will be hoping for the more difficult species like Bicknell’s thrush and gray-cheeked thrush. Knowing their call notes can help alert you to their presence.

There will be a dazzling diversity of our feathered friends on the move this month. The seasonal phenomenon of migration extends into September and October. Pay attention to the visitors in your yards and gardens.

Late summer offers interesting birding opportunities for birders

Photo by Steven Arnold/Pixabay • A great blue heron attempts to get a handle on a snake in preparation for swallowing its serpentine prey.

A pair of Carolina wrens has taken advantage of what was meant to be the temporary storage of some boxes on the front porch to claim the interior of one of the cardboard containers as a nesting location.

In the latter days of summer, usually a lackluster period for birdwatching, there are still some interesting behaviors or actions on the part of our feathered friends to provide some points of interest.

Wrens already have a reputation for nesting in some unusual locations. My introduction to the Carolina wren took place in my childhood when a pair of these wrens nested in an old apron my grandmother used as a bag for her clothespins. Other unusual locations for wren nests that I have found over the years included the interior of a plastic shopping bag hanging from a nail in my garage and an attempt to nest in the exhaust vent for my clothes dryer. I’ve also seen them nest in hanging flower baskets.

Photo by Jean Potter • A Carolina wren creeps along a fence.

The world’s 88 species of wrens are, for the most part, the quintessential “little brown birds,” but that hasn’t kept them from acquiring some interesting and descriptive common names. Some examples include the tooth-billed wren, flutist wren, riverside wren, whiskered wren, happy wren, musician wren, timberline wren, speckle-breasted wren, white-breasted wood wren and giant wren. The last species on the list resides in Mexico and is indeed a “giant” among a family of tiny birds, reaching a length of almost nine inches and weighing all of 1.8 ounces.

I’ve also been monitoring a great blue heron lurking along the creek that flows past my home. A collapsed foot bridge (thanks to Helene) still spans the creek and provided, at least from the heron’s perspective, a means of concealment from my prying eyes when I stepped onto the front porch. The heron ducked under the bridge and slowly stepped downstream, out of sight and presumably what the bird thought would be out of mind. But I tricked the heron, stepping back inside the house and waiting for It to reappear. I stepped into view again and the heron, instead of taking flight, repeated its earlier actions, skirting beneath the bridge and wading downstream. I could probably have continued this game of peek-a-boo, but I felt that I had imposed on the heron long enough. The bird evidently desired to try its luck fishing upstream beneath a shady overhang of branches from trees growing along the creek banks. I stepped back inside, peeked out a window and watched the heron move in a slow, stately manner, but this time the bird headed up the creek.

All herons are skillful anglers, so I am confident that the bird probably managed to catch an unwary frog or fish. As the tallest heron in North America, the great blue heron boasts a diverse diet. These birds, armed with a dagger-shaped bill, excellent vision and quick reflexed, prey on rodents, amphibians, snakes, fish and even small alligators. Basically, a great blue heron will eat anything it can swallow.

Photo by Bryan Stevens • A great blue heron’s quick reflexed and dagger-like bill make it a formidable predator.

Other herons around the world with descriptive names include purple heron, white-bellied heron, black-headed heron, great-billed heron, whistling heron, pied heron and Goliath heron. The latter, as its name suggests, is a giant among herons.

There’s more to report on the birding front. Hummingbird numbers are on the rise again. After the usual summer lull, the resident ruby-throated hummingbirds have raised their profile, visiting daily at feeders as well as blooming flowers. Female hummingbirds have had time to raise their young. In fact, many of the hummingbirds visiting your yards and gardens at this time of year are probably birds born earlier in the season. In a couple of months these young birds will make their inaugural migration across the Gulf of Mexico to reach winter grounds in Central America. Until that time, hang a sugar water feeder, grab a lawn chain and enjoy the hours of no-cost entertainment provided by these feisty, flying gems.

So, although the summer doldrums do make birds scarce at times, just know that they’re still out there. In the meantime, nature offers plenty of other engaing wildlife. During the day, it’s fun to look for butterflies and dragonflies. After dark, there’s always moths and lightning bugs.

Keep in mind, it’s not always the visuals. For instance, the past couple of nights I’ve enjoyed listening to an Eastern screech-owl’s nocturnal serenade with its trembling wailing call that gives this small owl its name.

Regional spring bird count finds 148 species

Photo by Bryan Stevens • Ruby-throated hummingbirds have settled into a comfortable summer routine throughout the Northeast Tennessee region.

The 82nd consecutive spring bird count was held Saturday, May 3, with 44 observers in 15 parties. The survey tallied 148 species, which is slightly below the recent 30 year average of 150 species. The count is conducted by the Elizabehton Bird Club, which will also conduct two summer counts this month. One of these counts is held in Carter County and the other in Unicoi County.

The spring count is a regional survey that includes all Northeast Tennessee counties: Carter, Johnson, Sullivan, Unicoi and Washington.

Compiler Rick Knight shared some observations. Noteworthy sightings included common merganser, black-billed cuckoo, willow flycatcher, vesper sparrow and bobolink, as well as prothonotary and cerulean warblers. A total of 31 species of warblers made this year’s count. A record number (24) for Swainson’s warbler provided an indication that this species is locally abundant during the nesting season.

The 17 fish crows reported by six parties provided a good example of the local expansion of this species. The 17 common ravens, once not so common in the region, were reported by eight of the count parties.

“I’ve had my hummingbird feeders up for a few weeks, but finally this afternoon (April 14) at 4 p.m. a female hummer had one all to herself,” Michelle Sparks, a resident of Bluff City, wrote to me by email.

“Yesterday (April 14) I saw a hummingbird check out our feeder,” Donald Beck emailed me.

“It did not drink and I have not seen it any time since,” Donald, a resident of Bray Road in Stanley Valley in Rogersville, reported.

“Was it just on its way north?” Donald also asked.

It’s true, I noted in my response to his question, that many of these first hummingbird sightings are not the birds that will spend the summer months with us. Many of these “early” hummingbirds will continue migrating farther north, but others will arrive, like what they see and decide to stick around.

Diane Hensley Silvers posted on April 16 in a Facebook comment that hummingbird numbers have only increased since the first one arrived.

“I have several now,” Diane wrote. “They arrived at my house in Washington County about 10 days ago.”

Tennessee’s Watchable Wildlife offers an online profile for the ruby-throated hummingbird, including interesting information about how such a tiny bird makes its phenomenal crossing of the Gulf of Mexico each spring to return to the eastern United States.

To accomplish this tremendous migratory crossing, a hummingbird will double its body mass by fattening on nectar and insects in the weeks prior to departure.

No hummingbird species other than ruby-throated hummingbird breeds in Tennessee, but several Western species have been found in the state during the non-breeding season. They arrive anytime after late August and usually depart in April. At least seven western species of hummingbird has been recorded in the Volunteer State, including rufous, black-chinned, Allen’s, Anna’s, calliope and broad-tailed hummingbirds.

There’s also a couple of reports of a green violet-ear, a species that is usually found in forested regions of Mexico and Nicaragua. The species has ventured into Tennessee twice, being documented in Memphis in September of 2007 and in Montgomery County in July of 2020.

I’ve seen several of these western “visitors” throughout the years, but my greatest affection is still attached to the ruby-throated hummingbird.

Most hummingbirds impress with their size, or rather the lack of it. It’s that tiny size that has prompted people to describe them as “miracles” from the time the first European explorers sailed to the New World in the late 1400s. When Spanish explorers first encountered them, they had no equivalent birds in Europe to use as a reference. They referred to hummingbirds as “joyas voladoras,” or flying jewels.

If your yard offers some trees and shrubs, necessary for perching, you can attract ruby-throated hummingbirds. It pays to have a feeder available with a fresh mixture of one part sugar to four parts water. This is the formula that closely matches the sweetness of nectar available from flowers. In warm conditions, you’ll need to change out the mixture every few days. Give the feeders a scrubbing and rinse while changing out the sugar water. Then sit back and enjoy the antics of these pint-sized delights.

Birds make use of various strategies to attract and keep mates

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.

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.

Winter’s ducks begin arriving in region

Photo by USFWS • A pair of green-winged teal swim together through a wetland.

Some interesting waterfowl have spent at least part of the winter at the pond at Erwin Fishery Park and a nearby fenced lagoon at the back of the park.

Some of the visitors since the start of the new year have included green-winged teal, American black duck, lesser scaup and Northern pintail. The scaup is a species of diving duck while the others are what are referred to as “dabbling” ducks. Diver and dabbler refers basically to the manner in which these ducks forage for their food.

The familiar mallard is probably the best known dabbling duck, but other dabblers include American wigeon, gadwall and Northern shoveler. Dabbling ducks generally feed in shallow water.

The green-winged teal is the smallest of North America’s dabbling ducks. There are two other close relatives of the green-winged teal in North America – the blue-winged teal and cinnamon teal. I’ve seen the green-winged and blue-winged at many locations in the region. I saw my only cinnamon teal during a trip to Utah and Idaho in 2003.

The Northern pintail that spent some time at Erwin Fishery Park was a hen with a more subtle appearance than adult male pintails.

This can be a species difficult to find in Northeast Tennessee. The website All About Birds notes that Northern Pintails are common, but their populations declined by about 2.6% per year resulting in a cumulative decline of about 75% between 1966 and 2019, according to the North American Breeding Bird Survey. The Partners in Flight organization estimates the global breeding population at 5.1 million.

Photo by Bryan Stevens • The Northern pintail is a dabbling duck, so classified due to its way of foraging for food in shallow water.

 

Elegant is a useful word for describing pintails. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-brown head down its neck to its mostly white undercarriage. The drake also has attractive gray, brown and black patterning on its back and sides. The hen’s plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. She has the same slender shaper as the male. Her tail feathers are long but don’t match the male’s namesake tapered tail feathers.

The Northern pintail is a cosmopolitan duck that also ranges into Europe, the Middle East, India and Asia. Other pintails include white-cheeked pintail, yellow-billed pintail and Eaton’s pintail. The latter species is restricted to the island groups of Kerguelen and Crozet in the southern Indian Ocean. The species was named after the English explorer, naturalist and entomologist Alfred Edwin Eaton. He served as the vicar of Shepton Montague in Somerset in England. Born in 1944, he died in 1929 at age 84.

Our region offers some dependable locations for looking for winter ducks, as well as other wintering waterfowl such as geese, grebes and loons. Accessible locations for looking for ducks during the winter season include Wilbur Lake near Elizabethton and Osceola Island Recreation Area below the tailwaters of Holston Dam in Bristol. Of course, any farm pond not frozen over is a potential location attractive to wandering waterfowl.

 

A duck known as the common merganser has expanded its summer nesting range to include the Nolichucky River and Watauga River. Twenty years ago this species, despite its name, was far from common in the region. It’s too early to tell whether changes wrought by last fall’s flooding from Hurricane Helene will affect this duck’s nesting attempts along these two rivers.

One difficulty in finding ducks in recent weeks has been the deep freeze gripping the region and turning almost all open water into ice. The widespread cold could help convince waterfowl from farther north to head south in the hope of less frigid conditions. My hope is that at least a few of those ducks will stop off at places like the pond at Erwin Fishery Park.

Ducks that aren’t too difficult to locate during winter in the region include bufflehead, ring-necked duck and hooded merganser. Other possible visitors include redhead and canvasback. If the Northern pintail is the most elegant of the dabbling ducks, the canvasback ranks as the most majestic of the diving ducks.

Ducks are interesting to observe. Binoculars and spotting scopes can make the process easier. Most ducks are social birds. Flocks, or rafts, of ducks display interesting interactions. In addition to the familiar “quack” of the mallard, different ducks produce a variety of hoots, whistles, hisses and other vocalizations.

Seeing Yellow: Visit from an odd cardinal surprises local couple

Photo by Bryan Stevens • A male Northern cardinal leads a young cardinal to food sources.

Unicoi resident Bobby Davis called me last week to share news about a sighting of a yellow cardinal. Bobby said that he and his wife, Tressa, have two bird baths and a hummingbird feeder in their yard and are in the habit of watching the comings and goings of their feathered friends. At 1 p.m. on Tuesday, Aug. 8, they noticed a yellow cardinal in the yard near some rhododendrons.

A “yellow” cardinal is simply a Northern cardinal that has inherited a rare genetic condition that causes the bird’s feathers to turn yellow instead of red.

A news item posted to a website for The Wood Thrush Shop in Nashville relates the story of a backyard feeding station in Harriman, Tennessee, in Roane County that was visited by a yellow Northern cardinal on a regular basis.

Yellow Northern cardinals have been seen in at least four different states the last 10 years but remain a rarity.

The article explained that the yellow coloration in affected cardinals is caused by a rare genetic mutation. The colors red, orange and yellow in a bird’s feathers are created with carotenoid pigments derived from the foods they eat. In the male Northern cardinal, yellow pigments from the diet apparently are converted to red by a specific enzyme. In a very rare genetic mutation, probably affecting fewer than one in a million cardinals, that enzyme is lacking, so the conversion to red doesn’t occur and the feathers are bright yellow instead.

Back in May of this year, a yellow cardinal given the name Maize was spotted in Alabama. That sighting took place less than 15 miles from a location that hosted another yellow cardinal in 2018. Was Maize a descendant of that yellow cardinal spotted six years ago?

Perhaps the yellow cardinal will stick around at Bobby and Tressa’s home. Bobby informed me that they have an ordinary pair of red cardinals that resides in their yard, but he noted that the three birds have not interacted.

•••

Interestingly enough, there is a bird with the actual name yellow cardinal, but it is not closely related to the Northern cardinal. This South American bird has the scientific name of Gubernatrix cristata and is a member of the tanager family.

The yellow cardinal was formally described in 1817 by the French ornithologist Louis Pierre Vieillot under the binomial name Coccothraustes cristata. The word “cristata” means crested or plumed.

This yellow cardinal ranges in Argentina, Brazil, Paraguay and Uruguay. Its natural habitats are dry savanna, temperate shrubland, subtropical or tropical moist shrubland and temperate grasslands. The yellow cardinal is threatened by habitat loss and from pet trade trappers for sale as exotic pets. Males are trapped at a higher rate than females, and the yellow cardinal is considered endangered due to the constant entrapment. If recent counts are accurate, only about 1,000 t0 2,000 of these birds still exist.

Pyrrhuloxia, also known as desert cardinal, is related to the Northern cardinal. 

The Northern Cardinal, on the other hand, is an abundant, beloved songbird. There’s additional evidence to put forward as testimony to the popularity of the Northern cardinal. It’s the official state bird of seven states: Virginia, North Carolina, West Virginia, Ohio, Illinois, Indiana and Kentucky. Only the Northern mockingbird, which represents five states as official state bird, even comes close to the Northern cardinal in this respect.

Cardinals are a widespread species, ranging westward to the Dakotas and south to the Gulf Coast and Texas. The southeastern United States was once the stronghold of the cardinal population. In the past century, however, cardinals have expanded their range into New England and Canada. These birds have even been introduced to Hawaii.

The Northern cardinal has only two close relative in the genus Cardinalis. The pyrrhuloxia, also known as the desert cardinal, ranges throughout Arizona, New Mexico and Texas, as well as in Mexico. The third relative is known as vermilion cardinal and is found in Colombia and Venezuela. This bird suffers some losses to the exotic pet trade, but its numbers have managed to remain fairly stable.
