Use autumn to get ready for bird-feeding season

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.

• 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.

Red-bellied woodpeckers, other birds raise their profile during recent snowstorm

Leave a reply

Photo by Bryan Stevens • A red-bellied woodpecker makes a tentative approach to a feeder stocked with sunflower seeds. Red-bellied woodpeckers are fairly common in the region.

I’m sure many share my sentiment that with February almost in the rear-view mirror it could be hoped that winter might be nearly at an end.

That misguided hope was dashed last week when another winter storm struck the region, accompanied by another blast of Arctic chill. At least the birds didn’t seem to mind terribly.

Dark-eyed juncos, Eastern towhees, song sparrows and American goldfinches flocked to my feeders. Another bird’s persistent “churr” call made the presence of a red-bellied woodpecker known even before I managed to sight one visiting one of my feeders.

Among the woodpecker family, the red-bellied and red-headed woodpeckers are close cousins, belonging to a genus of those tree-clinging birds known as Melanerpes. The term, translated from Latin, means “black creeper.” Indeed, many of the two dozen members of the Melanerpes genus have an extensive amount of black feathers in their plumage.

Other members of the genus include woodpeckers from the Caribbean, as well as from Central and South America. Some of them have quite colorful names, such as yellow-tufted woodpecker, golden-cheeked woodpecker and the accurately named beautiful woodpecker, a native of Colombia.

Photo by Bryan Stevens • Red-bellied woodpeckers are common throughout the southeastern United States.

The red-bellied woodpecker is one of the most widespread members of this genus with a range that extends from southern Canada to northeastern Mexico, as well as the eastern United States as far south as Florida and as far west as Texas. A century ago the red-bellied woodpecker was almost exclusively a southeastern bird, but it has expanded its range northward and westward considerably in the last 100 years. Its southern origins are hinted at in its scientific name of Melanerpes carolinus, which can be roughly translated as “black creeper of the Carolinas.”

It’s also named for a characteristic of its appearance that is not particularly prominent and difficult to observe. The faint tint of red that tinges the white belly feathers is extremely difficult to observe when this woodpecker is hitching up the trunk of a large tree. Because males, and females to a certain extent, have a red cap, the species has been erroneously referred to as a “red-headed woodpecker” by many casual observers. The true red-headed woodpecker, however, has an entirely red head and a plumage pattern that, considering its color trio of red, white and blue-black, is downright patriotic. The red-headed woodpecker (Melanerpes erythrocephalus) is about the same size as the red-bellied woodpecker.

All woodpeckers are noisy when the mood strikes them, but the red-headed and red-bellied have always struck me as rather more clamorous than some of their relatives. The most common call of the red-bellied woodpecker is a sort of rolling “churr” repeated frequently while the bird is on the move from tree to tree.

To enjoy close views of the red-bellied woodpecker, provide plenty of peanuts, sunflower seeds and suet cakes. During the recent snowstorm I would no doubt have enjoyed even more views of the visiting red-bellied woodpecker if I hadn’t been out of suet cakes. The offerings of sunflower seeds and peanuts, I’m happy to report, were gratefully accepted.

Photo by Bryan Stevens • A red-bellied woodpecker climbs snow-covered branches.

If there are any of these woodpeckers in the woods nearby, they will find these food offerings in short order. All my research indicates the same is true of red-headed woodpeckers, but I’ve never observed this woodpecker at my home. I’ve seen red-headed woodpeckers in Tennessee, Virginia and South Carolina, but their populations are somewhat localized. Woodlands dominated by oak trees are often inhabited by both these woodpeckers, which are fond of the acorns produced by these trees.

One reason the red-headed woodpecker may be less common than its cousin relates to its fondness for hawking for flying insects along roadsides. The woodpeckers are frequently struck by cars when swooping after their winged prey. Historically, the American chestnut and beech trees also provided much of the mast crops consumed by these birds. With the extermination of the chestnut and the scarcity of beech in some locations, the red-headed woodpecker now depends on oaks and acorns. In fact, this woodpecker is rarely encountered outside of woodlands with an abundance of oak trees.

At feeders, red-bellied woodpeckers are prickly customers that often refuse to play nice with other birds. I’ve seen them stare down other large feeder birds, including blue jays, mourning doves and evening grosbeaks. With its large bill, the red-bellied woodpecker commands some respect.

Anyone who has hosted these birds knows they are a welcome visitor to any yard. Who knows? Some day I may even get a visit from the elusive red-headed woodpecker, which is the only woodpecker that resides in the region to thus far avoid my yard.

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

Leave a reply

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

“The kon-ke-ree song of the male red-winged blackbird is a sure indication that spring is on the way,” according to a profile located at the Tennessee Watchable Wildlife website.

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

The male red-winged blackbird is a very aptly named bird. Glossy black males sport red wing patches that are often trimmed with a narrow band of yellow feathers. By contrast, female red-winged blackbirds are mostly brown birds that could easily be mistaken for large sparrows. Both sexes have sharply pointed bills.

Red-winged blackbirds are fond of wetlands. Any marsh or even a damp field or flooded pasture is likely to attract a few resident red-winged blackbirds. Females choose nesting locations in cattails or other marsh vegetation. She usually lays three or four eggs. Although she does receive some help from the male, most of the responsibility for raising the young is left to her.

There is a reason that male red-winged blackbirds are not always quite as engaged as females in feeding and tending their young. Males are often polygynous, which means that males will often court multiple mates. His time is often occupied defending females and their respective nests from the advances of other male red-winged blackbirds.

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

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

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

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

Other relatives of the red-winged blackbird in the United States include the tricolored blackbird found along the Pacific Coast and the yellow-headed blackbird resident in wetlands west of the Great Lakes. Rusty blackbird, common grackle and brown-headed cowbird are other species of blackbirds found in Tennessee, Virginia and North Carolina.

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

Birds make use of various strategies to attract and keep mates

Leave a reply

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

 

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

Aerial acrobatics designed to impress

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

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

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

Birds bearing gifts

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

The way to the heart is through the stomach

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

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

May I have this dance?

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

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

Synchronized swimming

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

Good housekeeping seal of approval

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

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

Club posts 82nd annual Elizabethton Christmas Bird Count results

Leave a reply

Photo by Scott/Pixabay • A blue jay perches at a suet feeder.

The 82nd Elizabethton Christmas Bird Count was held Saturday, Dec. 14, with 24 observers in six parties.

Unfortunately, I had to miss the count for the first time in almost a decade due to having contracted my first cold since 2019. I keep track of these things, especially when they interrupt the holiday season.

According to compiler Rick Knight, this year’s CBC tallied 71 species, with an additional three species seen during “count week,” which is defined as three days before or after count day. The three species found during count week were American wigeon, killdeer and pine warbler.
The total was just below the recent 40-year average of 72 species. The all-time high was 85 species recorded in 2017.

Here’s the list:
Canada goose, 302; wood duck, 2; American wigeon, 1; mallard, 65; green-winged teal, 2; ring-necked duck, 5; bufflehead, 143; hooded merganser, 3; red-breasted merganser, 1; and common merganser, 4.
Wild turkey, 26; pied-billed grebe, 10; rock pigeon 106; Eurasian collared-dove, 2; mourning dove, 108; killdeer, 1; Wilson’s snipe, 1; ring-billed gull, 9; double-crested cormorant, 1; great blue heron, 9; black vulture, 18; and turkey vulture, 21.Cooper’s hawk, 5; bald eagle, 6; red-shouldered hawk, 2; red-tailed hawk, 15; Easter screech-owl, 6; great horned owl, 1; and barred owl, 2.
Belted kingfisher, 12; red-bellied woodpecker, 30; yellow-bellied sapsucker, 8; downy woodpecker, 26; hairy woodpecker, 2; Northern flicker, 32; and pileated woodpecker, 19.
American kestrel, 16; Eastern phoebe, 13; blue jay, 107; American crow, 339; fish crow, 1; and common raven, 10.
Carolina chickadee, 102; tufted titmouse, 77; ruby-crowned kinglet, 11; golden-crowned kinglet, 17; cedar waxwing, 103; red-breasted nuthatch, 8; white-breasted nuthatch, 27; and brown creeper, 10.

Hans Toom/Pixabay • A gray catbird found on this year’s Elizabethton Christmas Bird Count represents a somewhat unusual winter sighting for the species.

Carolina wren, 104; winter wren, 9; gray catbird, 1; Northern mockingbird, 55; European starling, 369; Eastern bluebird, 108; hermit thrush, 11; and American robin, 181.
House sparrow, 34; house finch, 73; purple finch, 2; American goldfinch, 34; chipping sparrow, 18; field sparrow, 9; dark-eyed junco, 151; white-throated sparrow, 56; song sparrow, 125; swamp sparrow, 7; Eastern towhee, 10.
Eastern meadowlark, 11; orange-crowned warbler, 1; pine warbler, yellow-rumped warbler, 98; and Northern cardinal, 118.

Knight noted that highlights from the count included fish crow, gray catbird and orange-crowned warbler.

Other notable species include red-breasted and common mergansers and Eurasian collared-dove.

There are always some notable misses. This year the count failed to find horned grebe, sharp-shinned hawk, fox sparrow and white-crowned sparrow.

The first Christmas Bird Counts were conducted on Christmas Day (Dec. 25) in 1900. The annual census arose from a proposal made by famed ornithologist Frank M. Chapman. According to Audubon.org, these yearly counts, conducted throughout the country, have provided a wealth of data over the past century.

Observations made due to CBCs have helped Audubon researchers, conservation biologists, wildlife agencies and other interested individuals to study the long-term health and status of bird populations across North America. When combined with other surveys such as the Breeding Bird Survey, the data provides a picture of how the continent’s bird populations have changed in time and space over the past hundred years.

The concept of the Christmas Bird Count, according to the website for the National Audubon Society, arose from a less than bird-friendly custom prevalent at the turn of the 20th century. So-called sportsmen would conduct a “Side Hunt,” a rather blood-thirsty Christmas custom that saw hunters competing to see who could score the largest amount of feathered and furred corpses.

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

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

I think other bird lovers will join me in celebrating Chapman’s wonderful idea, which has continued strong for the past 125 years.

Birds have developed ways of dealing with cold

Leave a reply

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Cardinal a natural symbol for Christmas

Leave a reply

Photo by Bryan Stevens • A male Northern cardinal visits a feeder on a snowy afternoon.

Merry Christmas. This week’s newspaper is coming out on Christmas Day and, as is my usual custom on this holiday, I want to share my enthusiasm for the Northern cardinal, one of my favorite birds.

I’ve also come to believe that the cardinal is also an excellent feathered symbol for the Christmas holiday. Anyone who provides sunflower seeds at a bird feeder has most likely received visits from this bird.

Individual cardinals around my home have become very accustomed to my presence. Some of them have even learned my routine and know when to anticipate my daily stocking of the feeders with sunflower seeds.

I have always enjoyed watching cardinals. The beauty of both male and female cardinals is undeniable. They’re usually nervous, twitchy birds, so it has been fun watching some of the resident cardinals grow accepting of my presence.

The Northern cardinal, especially the brilliant red male, stands out against a winter backdrop of snow white, deep green or drab gray. Over the years, the cardinal has also become associated with the Christmas season.

How many Christmas cards have you received this holiday season with a cardinal featured in the artwork? I’d wager that at least a few cards in any assortment of holiday greetings will feature the likeness of a Northern cardinal.

There is a possible reason that male cardinals try to outshine each other when it comes to their bright red plumage. According to the website Tennessee Watchable Wildlife, brighter red male cardinals are able to hold territories that have denser vegetation, feed young at higher rates and have greater reproductive success than males with feathers of a duller hue.

The Northern cardinal belongs to a genus of birds known as Cardinalis in the family Cardinalidae. There are only two other species in this genus, and they range across North America and into northern South America. The two relatives are the pyrrhuloxia, or Cardinalis sinuatus, of the southwestern United States, and the Vermilion cardinal, or phoeniceus, a bird found in Colombia and Venezuela.

The Northern cardinal is a native and abundant bird. 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 20th century, however, cardinals have expanded their range into New England and Canada.

The cardinal accepts a wide variety of food at feeders. Sunflower seed is probably their favorite, but they will also sample safflower seed, cracked corn, peanuts, millet, bakery scraps and even suet. While we may get the idea that cardinals feed largely on seed, that is a misconception based on our observation of the birds at our feeders. Cardinals away from our feeders eat insects and fruit, including the berries of mulberry, holly, pokeberry, elderberry, Russian olive, dogwood and sumac.

The cardinal uses its large beak to efficiently hull sunflower seeds or deal with other foods foraged in field and forest away from our feeders. The large, heavy beak hints at the cardinal’s kinship with birds such as tanagers and grosbeaks.

In fact, some of America’s early naturalists referred to the bird as “cardinal grosbeak.” Other common names include the apt “redbird” moniker and “Virginia nightingale.”

Even once the holidays are past, there’s nothing like a glimpse of a Northern cardinal to add some cheer to a bleak winter day. It’s not surprising that such a popular bird has also become associated with many trappings of the Christmas season.

“You see cardinals on greeting cards, stationery, paper plates, paper napkins and tablecloths, doormats, light switch plates, candles, candle holders, coffee mugs, plates, glasses, Christmas tree ornaments and lights, bookmarks, mailboxes, Christmas jewelry,” writes June Osborne in “The Cardinal,” a book about this popular bird.

“And the list goes on,” Osborne writes. “Cardinals have become an integral part of the way that many people celebrate the holiday season.”

I can be included among such people. My Christmas decorations include an assortment of cardinal figurines and ornaments. There are other birds — doves and penguins for example — associated with the holiday season, but for me the holidays magnify the importance of one of my favorite birds. The cardinal, in its festive red plumage, appears made to order for a symbol of the holiday season.

I’m hoping you enjoy your Christmas and that at least a few cardinals and other birds fly your way.

Winter season offers a chance to get to know special little wren

Leave a reply

 

 

 

Willfried Wende/Pixabay • Outside of the Americas, there is only one species of wren. In the Americas, this wren is known as the winter wren.

Note: I’m on vacation. Please enjoy this column originally published in December of 2017.

Of late, every time I step outside my front door I’ve incurred the ire of a winter wren that’s taken up residency in my yard. This wren is a tiny bird among a family of birds known for small size, but it makes its presence known in unmistakable terms.

For starters, the winter wren is a noisy bird. The one living at my home arrived in late November and immediately claimed a niche to call its own. Any intrusion is met with a scolding chatter as the wren scurries low to the ground to drop out of view. In fact, the winter wren’s a very terrestrial bird. Observers are just as likely to see one of these wrens run across the ground as they are to see it take flight. I’m hopeful he will remain as winter’s grip tightens for the next couple of months.

The website All About Birds, managed by The Cornell Lab of Ornithology, offers advice on making a wren-friendly yard. “Landscaping with native plants is a good way to provide habitat for winter wrens,” according to the website. Other steps to take could extend to creating brush piles and ensuring some sections of the yard offers dense vegetation. The website also notes that this wren is often found making its home near streams.

In the summer, the winter wren often nests atop some of the high-elevation mountains in the region, especially ones with abundant fir and spruce trees. Otherwise, it’s mostly a winter visitor in the region. Other wrens common to the region include the Carolina wren and the house wren. In suitable habitats, especially during fall and spring migration, two other wrens — marsh wren and sedge wren — are observed occasionally in the region. Other wrens native to the United States include the rock wren, canyon wren, cactus wren, Pacific wren and Bewick’s wren.

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.

For the most part, wrens are birds of the New World. In fact, only the Eurasian wren represents the family in Europe, Asia and Africa. Experts recently split the winter wren into several different species, including the Pacific wren of the west coast of North America and the Eurasian wren of Europe, Asia and Africa.

Just as the winter wren thinks nothing of acting like a mouse when scurrying through leaf litter and over fallen logs in search of insect prey, this bird doesn’t hesitate to imitate mice by poking into shadowy holes in the ground or exploring the dark crevices of fallen logs. When winter temperatures drop sharply, many of these birds may cram themselves into a roosting hole to benefit from the communal heat from so many tiny feathered bodies in such close proximity. Winter wrens eat mostly insects and spiders, but in winter these birds will also eat some seeds and berries. Winter wrens rarely visit feeders, but a suet cake often attracts birds with similar dietary preferences, including kinglets and chickadees. A larger relative, the Carolina wren, is a common visitor to feeders.

In English and German lore, the winter wren was known as the “king of the birds.” Different tales provide varying explanations for how such a small bird earned such an inflated title. Ritual hunts were enacted in some European locations. These hunts, known as “wren hunts,” were conducted by “wren boys” who would parade through town on their quests. Wren Day fell on Dec. 26, which coincided with the holiday St. Stephen’s Day. Some myths blame the noisy bird for betraying the hiding place of Stephen, who was delivered up as a Christian martyr to his enemies due to the bird’s treachery. In some European cultures, various superstitions sprang up about wrens. For instance, in Scotland it is considered extremely unlucky to kill a wren.

Personally, I feel lucky to have the tiny winter wren spending time around my home and can guarantee no “wren hunts” will be staged here. At a time of year when feathered friends can be scarce, a winter wren is a welcome visitor.

Kinglets are tiny birds with huge appeal

Leave a reply

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Carolina chickadees are cheerful backyard birds

Leave a reply

Photo by Bryan Stevens • A Carolina chickadee visits a feeder for sunflower seeds.

I’ve learned not to leave my house without an offering for the local birds. Should I neglect to bring sunflower seed to fill the feeders in the yard as I leave for work in the morning, I must face a scolding from the resident Carolina chickadees.

I think I’ve become familiar enough with these tiny black, white and gray birds that I can tell the difference between a disappointed scolding, the result of leaving the house empty handed, and their jubilant and excited chattering as they invite other birds near and far to come and partake of the bounty when I remember to fill the feeders.

Chickadees have a namesake scolding vocalization — a strident chick-a-dee-dee-dee — that they use to communicate with each other as the move through dreary winter woodlands.

They and the tufted titmice, a closely related species, are among the birds most easily acclimated to human presence and activity.

Photo by Bryan Stevens • A Carolina chickadee endures a cold winter’s day.

On the mornings when I remember their sunflower seeds, the waiting chickadees are doing tiny hoppity dances in the branches of nearby trees and shrubs, barely able to contain their excitement. They barely give me time to move away from the feeders before they dart in, grab a seed and carry it off to quickly shell on a safe perch.

In the spring, the Carolina chickadee has a familiar “fee-bee-fee-bo” song that rings out in the woodlands around my home. Cavity-nesters, chickadees readily take to nest boxes provided by human landlords. We are about five months away from spring of 2025, but that’s all right. Early winter is a great time to make the acquaintance of the Carolina chickadee.

This diminutive songbird is at home in mixed or deciduous woods in the United States from New Jersey west to southern Kansas and south to Florida and Texas. The Carolina chickadee also ranges along the Appalachian Mountains, but on some of the higher peaks they are replaced by their cousin, the black-capped chickadee. In Tennessee, birders need to visit some of the higher peaks in the Great Smoky Mountains National Park in order to find black-capped chickadees.

Sunflower seeds are a favorite offering. They are also attracted by peanuts, suet and other varieties of bird seed. They comprise the nucleus of mixed flocks of various species, so they will also bring other birds into your yard and within easy viewing range. Some other members of the flock might include wrens, nuthatches, titmice and perhaps a couple of kinglets or a downy woodpecker.

It’s easy to attract chickadees to your yard. Shrubs and small trees, feeders stocked with sunflower seeds and perhaps a mesh cage offering a suet cake are sure to make these small birds feel welcome. If you want to witness the family life of chickadees, build or buy a box suitable for wrens and other smaller birds. That task can wait until February of March of next year. Chickadees will happily take up residence in the offered nesting boxes.

Once a pair of chickadees settles down into domestic bliss in the spring, they almost at once start work on the construction of a nest. These little songbirds, looking quite smart in their handsome black, white and gray feathers, build an exquisite nest. The primary nesting material is green moss, which they stuff into a natural cavity or bird box in great quantities. The female chickadee fashions a depression in the collection of moss. She lines this shallow basin with plant fibers as well as strands of fur or hair to provide soft cushioning for her eggs.

A female chickadee can lay a large number of eggs, with the clutch size ranging between three and ten eggs. Once the young hatch, both parents are kept busy delivering food to a large brood of hungry, noisy chicks. The young grow quickly, but they take advantage of the safety of their cavity nest and don’t depart for the wider world until 20 days after their hatching.

North America’s other chickadees include the aforementioned black-capped chickadee, as well as boreal chickadee, chestnut-backed chickadee, grey-headed chickadee, Mexican chickadee, and mountain chickadee. On a trip to Utah in 2003 and 2006, I saw both black-capped chickadees and mountain chickadees.

In other parts of the world, chickadees are known as “tits,” which is from an Old English word denoting small size. Worldwide, there are about 60 species of chickadees and tits, which are classified collectively under the scientific family name, Paridae. Other members of this family range into Europe, Asia and Africa, including species with colorful names like fire-capped tit, yellow-bellied tit, azure tit, green-backed tit and cinnamon-breasted tit.

Alas, in Northeast Tennessee, western North Carolina and southwest Virginia, we have only the Carolina chickadee, but these entertaining birds are sure to become the star attractions in yard and garden once they discover your feeders and begin providing their cheerful antics.
