Chasing Zunzun: Bahamas cruise resulted in sightings of flying gems

2 Replies

Continuing to bring you some vintage columns, I dug deep into my archives. I’ve traveled outside the United States on only one occasion from Jan. 22-24, 1999, during a family vacation. Sightseeing and shopping took a backseat to birding during a three-day cruise in the Bahamas. I fully documented my sightings in a “Feathered Friends” column published Feb. 14, 1999.

Two scheduled shore excursions during the cruise gave me opportunities to search for birds.

Two hummingbird species can be found in the Bahamas. The Cuban emerald, as its name suggests, is found in Cuba. It’s also found on several islands in the Bahamas. These dazzling birds are found in thickets and woodlands, as well as parks and gardens.

Another hummingbird species, the Bahama woodstar, is found nowhere else in the world.

Without much difficulty, I observed both species during my visit to the Bahamas. My observation of Cuban emeralds took place on Castaway Cay, a small island owned by Disney and reserved for use by those traveling aboard its cruise ships. Much of the island had been kept in a natural state with walking trails perfect for looking for birds. While others enjoyed the beach, I set off with my binoculars on the trails.

My mother and I observed a pair of Cuban emeralds that appeared to be a mother and her male offspring. On two occasions, we watched the female approach the young male for a feeding session. The young bird opened his bill in a wide gape and the female plunged her own long bill into his throat. The spectacle looked rather fearsome, but that’s how hummingbirds feed their young. I’ve observed one of our native ruby-throated hummingbird feeding her young in the same manner. Experts who have researched hummers insist there’s no danger that a mother hummingbird will skewer her offspring.

The young male being fed put on quite a show. He appeared almost completely lacking in fear and allowed me to approach within inches of his perch. At times, he also exhibited his own curiosity and buzzed around my head and face for a better look of his own.

His mother, not quite as confiding, kept her distance. She perched on branches about 15 feet off the ground. She observed us, but she never descended to feed the young male unless we withdrew to a comfortable distance.

I learned later that my brother and sister-in-law saw some Cuban emeralds at another location on the island, leading me to suspect that the Cuban emerald may be quite common on Castaway Cay in the Bahamas.

Male Cuban emeralds sport an iridescent green throat and breast with a long forked tail, white undertail feathers, and a long thin bill that is black on top and reddish-pink on the underside. Females look similar to males except with green upperparts along with a grayish throat and breast, and a slightly shorter and less forked tail.

The term “emerald” describes many different species of hummingbirds. In the Caribbean, this family includes Hispaniolan emerald and Puerto Rican emerald. These hummingbirds belong to the genus Chlorostilbon, which is Greek for “green glitter,” a perfect description of the metallic green appearance of their feathers. Since my writing of the original column, experts have reconsidered the classification of the Cuban emerald. Based on a molecular phylogenetic study published in 2014 and a 2017 publication, the North American Classification Committee of the American Ornithological Society moved the species to the resurrected genus Riccordia. The Cuban emerald’s scientific name is now Riccordia ricordii.

Prior to seeing the Cuban emeralds I got a brief but close look at a male Bahama woodstar visiting hibiscus and other flowers in a garden surrounding a swimming pool at a resort in Nassau, the capital of the Bahamas located on New Providence Island.

The Bahama woodstar bears a resemblance to our own ruby-throated hummingbird. Male Bahama wood stars boast a reddish-purple throat, green upperparts and a white breast bordered by a tinge of rufous. The bird’s forked tail feathers are also trimmed with rufous color. Males and females have a white spot behind each eye. They also have black bills that curved downward slightly at the tip.

The Bahama woodstar, which is roughly the same size as a ruby-throated hummingbird, is a member of the genus Calliphlox, which is Greek for “beautiful flame.” Since my original writing of this column, the classification of the Bahama woodstar changed after a 2014 study.

A former subspecies of the Bahama woodstar has been made its own species. The Bahama woodstar itself was moved into a new genus and given the scientific name Nesophlox evelynae. That former subspecies was upgraded to full species status and is known as the Inagua woodstar (Nesophlox lyrura), also called the lyre-tailed hummingbird. The species is endemic to the two islands of the Inagua district of the Bahamas.

It’s the Bahama woodstar that occurs in Nassau, so the species I saw in 1999 was truly the Bahama woodstar. The good news is that if I ever travel to the Great or Little Inagua islands in the Bahama archipelago I will have a chance to add a third species of Bahama hummingbird to my life list.

There are many other species of woodstars, including the little woodstar of South America, the purple-throated woodstar restricted to the west slope of the Andes in Colombia and Ecuador, and the endangered Chilean woodstar.

There are about 360 species of hummingbirds, all found in the New World and reaching their greatest diversity in Central and South America.

Both Cuban emeralds and Bahama Woodstars have strayed into nearby Florida, so it is possible to observe these two species outside of the Bahamas. Experts have speculated that the Inagua woodstar had very likely also strayed into Florida.

I’ll always remember my trip to the Bahamas and the opportunity to chase after zunzún, which is a Spanish word, particularly used in the Caribbean, for hummingbird. I greatly enjoyed my observations of the two hummingbird species I observed in the Bahamas. These sightings remain among my most memorable in my nearly four decades of birding.

Use autumn to get ready for bird-feeding season

Leave a reply

Bryan Stevens • A female Northern cardinal visits a hanging platform feeder for a winter meal of sunflower seeds.

I’ve enjoyed a decent amount of activity in my yard this fall, enjoying visits from ruby-throated hummingbirds and American goldfinches as well as brown thrashers and gray catbirds. I’ve also glimpsed a few warblers. As much as I enjoy fall, crowding into my awareness is the fact that cold weather will soon be with us again.

Even that fact, however, is not totally unwelcome. Winter’s a fine season for peering through the windows at the birds that flock to feeders. So, with the winter season looming just around the corner, now might be a good time to take some steps to make your yard and feeders more attractive and welcoming to our feathered friends.

Seeing all the activity in my yard during fall migration made me want to ensure that it remains attractive for those birds that choose to eke out a living during the colder months of the year in our region.

Here are a few suggestions of things to do this fall to make your winter bird feeding more productive. It’s better to do these outdoor chores now before winter truly put a nip in the air.

• Plant native trees that bear fruit. Autumn’s a recommended planting time for many trees, so consider checking with a local nursery about the selection of such native trees as American holly, serviceberry and red mulberry. It’s always good to select trees that provide fruit at different seasons to maximize the appeal of your plantings to birds. A flock of American robins or cedar waxwings, or even a pair of Northern mockingbirds, can quickly strip berries from a holly tree when conditions turn snowy and icy.

• Build or refurbish a brush pile. Fall’s a season for pruning, so take those discarded limbs and twigs to construct a protective shelter for songbirds. Shy birds that naturally avoid open spaces can be coaxed closer to feeders by having access to a tangle of sticks and brush. A brush pile offers a degree of protection should songbirds at your feeder need to find a quick hiding place when a hawk or other predator makes an unexpected appearance.

• Evaluate feeders. The winter season brings snow, ice and a flurry of renewed interest in bird feeders, so now is the time to clean and replace feeders. The elements are not always kind on feeders, so when it becomes apparent that a feeder is in poor condition, consider replacing it with a new one. It’s also important to give feeders a thorough cleaning. Using a mild bleach solution will help disinfect them and make feeding from them safe for our feathered friends. Just be sure to rinse throughly and then dry the feeder before hanging it back out.

Photo by Bryan Stevens • Field guides are an essential tool for bird identification.

• Take some steps to increase your enjoyment of the birds coming to your feeders. Invest in a good bird identification guide or app. I am a fan of a good field guide that I can hold in my hands while thumbing through the pages, but I know that many people prefer the convenience of an app that’s accessible through their smartphone. Some popular apps would include the Audubon Bird Guide, eBird and Merlin Bird ID. Some of my recommended field guides include Peterson Field Guide to Birds of North America and The Sibley Field Guide to Birds of Eastern North America. Identifying birds congregated in the winter at a feeder is often easier than trying to track them through the green canopy during the other seasons. Of course, you’ll want to be aware that some birds wear different plumages during the winter months. The guides and apps can help with these identification challenges.

• Upgrade your optics. Place a pair of binoculars on your Christmas list. Bring the birds closer to you with a reliable pair of binoculars. It will make all the difference.

• Don’t take down the sugar water feeders just yet. Although ruby-throated hummingbirds almost all depart in early October, other species of hummingbirds normally found in the western United States have reliably made appearances in the region in October, November and other winter months. Through the years, I have seen several of these seemingly out-of-place hummingbirds. Some of them remain at their host’s feeders for a brief stay of a few days or a couple of weeks, but some of these hummingbirds have extended their stay for several months, lingering throughout the winter months before eventually departing in February or March. The big question concerns whether these hummingbirds are truly lost and out of place. The answer, based on everything I have managed to learn, is that these hummingbirds are precisely where they want to be. For still unknown reasons, some of these western hummingbirds make a migration swing through the eastern United States. One thing is certain: You won’t see one of these “strays” unless you keep out a feeder with fresh sugar water. It’s not that difficult. After all, the ants and wasps that made a nuisance of themselves during warmer temperatures are no longer active. If it gets too cold, you can always move your feeders inside at night and put back outdoors at daylight. If you do happen to attract a winter hummingbird, please let me know. I love helping to document these rare visitors.

Late summer offers interesting birding opportunities for birders

5 Replies

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.

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

Leave a reply

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.

Ruby-throated hummingbirds stage their spring return to region

Bryan Stevens • A male ruby-throated hummingbird perches on a sugar water feeder.

In an article posted on March 27, Journey North, an organization and website that tracks migrating hummingbirds, announced that so far this spring, bird-watchers in 12 states had reported ruby-throated hummingbirds, but it’s still early in the season.

“So far, we have one sighting each in Kentucky and Tennessee and two in Arkansas, but we’re expecting more in the coming weeks,” noted the blog post by Journey North.

One week later, hummingbirds arrived in locations in Unicoi County, Carter County and Washington County in Northeast Tennessee.

Journey North is a citizen science project that engages citizen scientists in a global study of wildlife migration and seasonal change. It’s a fun way to track the migration of everything from hummingbirds to butterflies like monarchs.

“Hummingbirds are here!” Beverly King, a resident on Marbleton Road in Unicoi, wrote in an email. “We saw our first hummingbird today, Saturday, April 5.”

Beverly noted that she was excited to see hummingbirds slightly early this year.

“We usually see them about the 15th of the month,” she added. “Well, my feeders are now up. We could not tell if it was a female or a male.”

Erwin resident Amy Tipton sent me a Facebook message announcing that her parents had enjoyed a visit from a returning hummingbird.

“My parents, Edison and Emma Jean Wallin, had their first hummingbird of the season visit today, Saturday, April 5 at 4:30,” Amy wrote. “They live about a mile up Limestone Cove in Unicoi.”

Dianne Draper in Jonesborough shared on my Facebook page about her first hummingbirds of the season.

“Our first ones showed up on April 5,” she noted. “We had two.”

I’ve already seen my first hummingbird, as well. I have a bed of tulips blooming at my home. I planted them last fall and have been thrilled with their performance. I was outdoors admiring the tulips when I heard a brief but tantalizing buzzing noise. Although I scanned all around me, I failed to confirm that I’d heard a hummingbird.

A half hour later, however, while reading on my front porch, I saw my first hummingbird of 2025 when a male zipped up to one of my sugar water feeders. He returned twice while I stayed outdoors reading on a misty afternoon. He arrived at 4:14 p.m. on Sunday, April 6.

In 2024, I saw my first hummingbird on April 17 at 7:15 p.m. This year’s bird is certainly arriving earlier than is typical, but I was thrilled to see him.

Gayle Riddervold, who lives only a few miles from my home on Simerly Creek Road in Hampton, reported that she and Becky Kinder saw their first spring hummingbird on April 8.

Technically, TD, a follower of my “Our Fine Feathered Friends” blog, provided the earliest report of a hummingbird this spring. Of course, TD has the benefit of living in Texas, close to the Gulf of Mexico that these tiny birds must cross to return to the United States each spring.

The bird TD spotted arrived on Wednesday March 26, at 2:34 p.m. central time.

“A ruby-throated hummingbird male stopped at my feeder on my front porch a mile from Corpus Christi Bay after an hour of a rain shower,” TD wrote in a comment.

TD also reported that Corpus Christi has been in a drought so severe that residents have not been allowed to water outside since last fall.

TD’s hummingbird arrived with the first rainfall in more than two months.

“So I was watching the lovely rain when this hummingbird perched onto my hummingbird feeder,” TD wrote. “I have a very large window and hang four hummingbird feeders along the front porch.”

TD noted that the male’s iridescent ruby red around his neck resembled a scarf. “I named him Texas Tuxedo,” TD shared.

TD also saw a female hummingbird on Wednesday, April 2, at 7:15 a.m.

TD said the female hummer acted shy and fluttered around the feeder before feeling safe to perch for feeding.

It’s usually the case that females lag behind males in their annual migration back to the United States.

The hummingbirds are an amazing family of birds. There are an estimated 330 species of hummingbirds, all of which are found in the New World. Consider that these dazzling little birds have been given vividly descriptive names, such as cinnamon-throated hermit, red-tailed comet, blue-chinned sapphire, lazuline sabrewing, sparkling violetear, fiery topaz, green-tailed goldenthroat, bronze-tailed plumeleteer, amethyst-throated mountain-gem, peacock coquette, red-billed emerald, empress brilliant, purple-backed sunbeam, green-backed hillstar, orange-throated sunangel, black metaltail, marvelous spatuletail and blue-tufted starthroat.

The only hummingbird species to inhabit the eastern United States from spring to fall each year is the ruby-throated hummingbird, which is currently arriving at various points from Florida to Maine and westward to states like Illinois, Minnesota and Oklahoma and north into Canada.

To return each year, ruby-throated hummingbirds make an awe-inspiring and non-stop crossing of the Gulf of Mexico. Even more incredible, they make the trip again in the fall when they return to warmer locations in Central America to spend the winter months.

Ruby-throated hummingbirds lead relatively brief lives. The oldest known ruby-throated hummingbird was a female, according to the website All About Birds. She was at least 9 years, 2 months old when she was recaptured and rereleased in 2014 during banding operations in West Virginia.

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.

Seeing Yellow: Visit from an odd cardinal surprises local couple

Leave a reply

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.

Summer’s swallows are graceful, aerodynamic birds

Leave a reply

Tom Koerner/USFWS • A perched tree swallow surveys its surroundings..

They took their time this year, but the tree swallows are finally putting in appearances almost daily, especially on the string of sunny, hot days the region has experience lately. This pair of swallows has become frequent visitors since the middle of last month.

Based on their behavior, which primarily consists of aerial foraging over fields and a pond at my home, I’m convinced they are feeding young. They don’t, however, appear to be residing in any of my nest boxes. I’m simply glad they are nesting close enough to ensure frequent visits. It probably won’t be long before their young are soaring over the fields with them.

No matter where you live, you probably don’t have to go far to see one of the members of the bird family known as swallows. These graceful, aerodynamic birds are quite familiar to most people. If you spend much time at all outdoors during the summer months, chances are you’ve observed some members of this family.

It’s usually not too difficult to find five of the six species that are known to make Northeast Tennessee and Southwest Virginia their home from spring to fall. The more commonplace swallows are barn swallow and tree swallows, but during the summer months purple martins, cliff swallows and northern rough-winged swallows also call the region home.

Barn swallow and tree swallow are the two members of the family that are probably best known to people. They have adapted to life in both suburban and rural areas, which brings them into frequent contact with people.

These days, the barn swallow is as apt to nest in a parking garage or on an apartment balcony as inside a barn in the countryside. Once young swallows leave the nest, parents will park them on a perch as they continue to feed the still dependent young. Adults fly over nearby fields, foraging for insects that they catch on the wing and deliver back to the waiting, always hungry, young birds.

A freshly mown field is a magnet for swallows. I don’t know how the word spreads so quickly among these birds, but I’ve observed dozens of these birds descending on fields soon after they have been mowed for hay. At times, the birds arrive while the mowing is still taking place, swooping after insects stirred up in the tractor’s wake.

I haven’t observed any bank swallows in the region this year, but these members of the swallow family are rather hit-or-miss in the region. Because of their specialized nesting needs, bank swallows are localized in their distribution and not as widespread as their kin.

Cliff swallows nest beneath many local bridges. These swallows, which at one time nested primarily on rocky cliffs, hence their name, now frequently nest under man-made structures. These swallows make their jug-shaped nests out of mud and clay. These nesting “jugs” are all located in clusters beneath bridges and other structures. It’s a wonder that the parents flying in with food are able to tell their nests apart from the nearby seemingly identical nests of their neighbors.

Northern rough-winged swallows are opportunists when it comes to nesting. According to a profile written by Mark Johns with North Carolina Wesleyan College, this small swallow nests near rocky gorges, shale banks, stony road cuts, railroad embankments, gravel pits, eroded margins of streams and other exposed banks of clay, sand or gravel. They will also nest in old kingfisher burrows, protruding drainpipes, crevices in brick or stone structures such as dams, bridges or tunnels, gutters and culverts. Their nests are often built near open water.

The Northern rough-winged swallow ranks as one of the species with the longest common names in North America. It’s name consists of 26 letters and a hyphen, which ranks it one letter below both the Northern beardless-tyrannulet and a recently-created species — the saltmarsh sharp-tailed sparrow — which each have 27 letters and a hyphen. Formerly known as sharp-tailed sparrow, the species was renamed with “salt marsh” added to distinguish it from a relative, Nelson’s sparrow.

Purple martins, which rank as the largest member of the swallow family in North America, are famous for nesting in large colonies. Nesting facilities range from groupings of natural or artificial gourds fashioned into a nesting chamber, as well as large, multi-level condominium dwellings tailored for the specific needs of this communal bird. A colony can consist of several dozen to several hundred pairs of these birds. Only the adult male purple martin shows the iridescent, dark blue-purple plumage that provides the species with its name.

The tree swallow is my favorite, probably because a pair of these birds has nested in my yard for many years. Unlike other swallows, these cavity-nesting birds will readily accept nesting boxes. They compete with Eastern bluebirds for boxes, but the two species usually can work out a truce and settle down to nest in close proximity to each other. The iridescent blue-green male tree swallow, complete with white underparts and a forked tail, is a handsome bird and a welcome addition to the bird population in any yard or garden. Tree swallows enjoy water, so a nearby pond or creek is a boon for attracting these birds.

While only a few swallows range into the United States and Canada, a total of 83 species of swallows can be found worldwide. Some of the common names for these different swallows (and martins) are quite descriptive. A sampling includes white-eyed river martin, square-tailed saw-wing, white-headed saw-wing, grey-rumped swallow, white-backed swallow, banded martin, violet-green swallow, golden swallow, brown-chested martin, brown-bellied swallow, pale-footed swallow, white-bibbed swallow, pearl-breasted swallow, greater striped swallow, mosque swallow, fairy martin and chestnut-collared swallow.

Enjoy swallows while you can. They depart earlier than most of our other summer nesting birds. Once their young are out of the nest, they are soon forming large flocks in preparation for flying south.

Hooded warbler easily wins fans among birders

Leave a reply

Photo by Jean Potter • A male hooded warbler flits through the foliage of a rhododendron thicket.

The woods surrounding my home have been alive with birdsong. We’re almost ready to turn the calendar to June, but there’s been no diminishment in the fervor of the daily chorus.

The main members of the feathered choir are warblers. I’ve heard yellow-throated warbler, black-throated green warbler, black-and-white warbler, Northern parula, ovenbird, common yellowthroat and, my favorite, hooded warbler, morning and evening.

During the winter months when the hooded warbler absents itself from Northeast Tennessee, the species resides in the forests of Mexico, as well as in Belize, Costa Rica and other Central American nations.

Like many of the ruby-throated hummingbirds that make their home in the United States for the summer, the hooded warbler’s seasonal migrations take it across the vast open waters of the Gulf of Mexico. After that amazing crossing, these small songbirds disperse throughout the southeastern United States.

That birds as small as hummingbirds and warblers make this incredible migration twice yearly is one of nature’s most phenomenal feats of endurance. In a presentation by Kenn and Kimberly Kaufman that I attended six years ago, I learned that these tiny birds put on incredible fat reserves to help fuel their valiant Gulf crossings.

The warblers, also known as wood-warblers, are an exclusively New World family, numbering approximately 116 species. About 50 of these species make their home in the eastern United States and Canada for the spring and summer, departing in the fall and returning to tropical wintering grounds. Some are extremely bright and colorful birds. The hooded warbler is somewhere in the middle in a sliding scale that goes from dull to wow.

Other colorful warblers that share similar tastes in range and habitat with the hooded warbler include the American redstart, black-throated blue warbler and black-throated green warbler.

Readers who make it to the end of this weekly column will know that even my email address is a testament to my enthusiasm for the hooded warbler.

Hooded warblers nest in the woodlands around my home. So, from the time my favorite warbler returns in April until the last individual departs in October, I enjoy regular glimpses of this colorful and interesting bird. Like all warblers, the hooded warbler is quite energetic, dashing after tiny insects in the branches of shrubs and trees. Hooded warblers often forage close to the ground, which makes observing them easier.

Of course, birds are free to break the rules. One of my most memorable sightings of a hooded warbler involved a male singing from the upper branches of a dead pine tree. I’d estimate that the bird was at least 40 feet off the ground, singing his little heart out to attract a mate. I was standing on an elevated rise of land while the tree providing the warbler its perch was lower in a gully that actually placed bird and observer on a roughly level playing field.

The bird sang for many moments, which is not always the case with warblers. These birds tend to dash for cover at the slightest disturbance, but this enthusiastic male didn’t seem to pay and heed to the fact that most of its kin prefer to skulk in shrubs and dense rhododendron thickets no more than a few feet off the ground.

Back in the late 1990s, when I had just started out in birding, I observed two adult hooded warblers feeding a couple of young birds only recently out of the nest.

I was enjoying observing the sweet scene as the parent birds carried foods to the young birds, which begged incessantly and loudly when, unexpectedly, a song sparrow wandered into the scene.

The sparrow was brutally beset by the parent warblers, which attacked the intruder from all sides. The poor sparrow, having no clue to the reason for their ire, beat a hasty retreat. Sparrows are no threat, but that didn’t matter to these zealous parents.

When I first began birding, I was only dimly aware there was a family of birds known as warblers, which are now hands-down my overall favorite birds. The hooded warbler was one of the first birds I managed to identify on my own.

It’s one bird unlikely to be mistaken for any other. Every time I behold a hooded warbler, I marvel at the bird’s exquisite appearance. The gold and green feathers seem to glow brightly in the dim light of the shadowy thickets of rhododendron they prefer to inhabit. The black hood and bib surrounding the male’s yellow face stands out by virtue of its stark contrast from the brighter feathers. Large coal-black eyes complete the effect. The appearance of the male bird provides this species with its common name. The female has an identical yellow-green coloration as the male, although she is slightly more drab. She lacks the black hood and bib, although older females may acquire some dark plumage on the head and around the face. Both sexes also show white tail feathers that they constantly fan and flick as they move about in thick vegetation and shrubbery.

The warblers are, in short, an incredible family of birds. I’ve seen all but a handful of the species that reside for part of the year in the eastern United States. I still want to see a Connecticut warbler and cerulean warbler, as well as the endangered Kirtland’s warbler of Michigan and the golden-cheeked warbler of Texas.

I’ve come to think of the hooded warblers at my home as “my warblers.” There may be a kernel of truth to my belief. The website All About Birds in a profile on the species notes that a seven-year study conducted in Pennsylvania gave evidence that male hooded warblers are faithful to nesting territories from previous years. Approximately 50% of banded males were shown to return to the same area to breed again year after year.

So, some of those hooded warblers singing from the rhododendron thickets at my home are probably birds returning for consecutive spring seasons. Some of the warblers that returned back in April could be great-great-great grandchildren of those warblers that attacked the unfortunate song sparrow. At the least, it gives me pleasure to think so.

Tiny kinglets, gnatcatchers lead the charge among spring’s returning birds

Leave a reply

Photo by Pixabay • The blue-gray gnatcatcher’s diminutive size belies its defiant attitude. These birds are intensely territorial and brooks no intruders.

The ruby-crowned kinglets, which passed through last fall in October and November, have returned, retracing their migratory path for the spring season and making their presence felt at my home with their jittery call notes and songs.

Most of the more recent returning birds have been on the smaller side. In addition to ruby-crowned kinglets, which arrived on April 1, I saw and heard a tiny blue-grey gnatcatcher on March 31.

As their name suggests, kinglets are tiny birds. In fact, about the only North American birds smaller than kinglets are some of the hummingbirds. The kinglets, known outside North America as “flamecrests” or “firecrests,” 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. In addition to the two North American species, four other species of kinglets can be found in North Africa, Europe and Asia.

The gnatcatcher is also one of our smaller birds. I’ve always though that blue-gray gnatcatchers resemble a shrunken mockingbird. Like quarrelsome mockingbirds, gnatcatchers are noisy, scolding songbirds.

They are also determined to protect their nesting territories at all costs and will attack much larger birds. In North America, the gnatcatcher ranks in size with birds like kinglets and hummingbirds. Despite its diminutive status, the gnatcatcher acknowledges no superiors. According to the All About Birds website, blue-gray gnatcatchers are “fiercely territorial” and use vocal displays and postures to in intimidate other birds. They may chase a rival as far as 70 feet. If all this fails to deter an intruder, a gnatcatcher will escalate to midair confrontations.

Gnatcatchers don’t hesitate to call for reinforcements when warranted. With persistent squeaking they will drum up a brigade of feisty, feathered fighters to repel intrusions by potential predators too large for a gnatcatcher and its mate to handle on their own.

Ruby-crowned Kinglet

There are two species of kinglets in North America.

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 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 a yellow crown patch, but only the male ruby-crowned kinglet boasts a scarlet patch of feathers atop the head. Observers can expend a lot of energy trying to get a look at the crown patches, which are typically only displayed when the bird is agitated.

There are 17 species of gnatcatchers. Most of these species reside in Central and South America. Some of the other species found in North America include California gnatcatcher and black-capped gnatcatcher.

Kinglets are very active birds. If warblers can be described as energetic, the kinglets are downright frenetic in their activities. The kinglets almost never pause for long, flitting from branch to branch in trees and shrubs as they constantly flick their wings over their backs. These bursts of hyperactivity can make them difficult to observe. Although small in size, these birds more than compensate for it with a feisty spirit that does them well through the harsh winter months.

Gnatcatchers are also constantly on the move, flicking their tails and darting through the branches of trees just starting to put out new green leaves. They glean caterpillars and small insects from the undersides of leaves to help fuel their demanding metabolism.

Kinglets and gnatcatchers often join mixed flocks comprised of other species of birds, some of which are regular feeder visitors. Perhaps by observing their flock counterparts, some kinglets have learned to accept feeder fare such as suet, meal worms and chopped nuts. Away from feeders, kinglets mostly feed on a range of small insects and arachnids. Gnatcatchers are strictly eaters of insects, but while a feeder holds no attraction for them, their curious nature often makes these tiny bird quite approachable.

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.

Likewise, gnatcatchers live brief lives. The oldest known blue-gray gnatcatcher was a male, and at least four years, two months old, when it was recaught at a banding station in Pennsylvania and rereleased, according to the All About Birds website.
