Reader reports visit from rufous hummingbird

An email from Bristol resident Ralph Beamer offered a timely reminder about the need to keep a watchful eye on our sugar water feeders even as most of the ruby-throated hummingbirds depart the region.

“For the past week, I have had a red humming bird coming to the feeder,” Ralph explained in his email. He added that he had never seen a hummingbird like this recent visitor.

“Have you had any reports of a similar sighting?” Ralph asked.

Ralph is the first person to make such a report this fall, but sightings of a species of hummingbird other than the expected ruby-throated hummingbird are becoming more commonplace each year. Once the numbers of ruby-throated hummingbirds are reduced as these tiny birds migrate from the region, noticing an unusual hummingbird at a feeder becomes even easier.

In a reply to Ralph’s email, I sought more information on the hummingbird’s coloration. He confirmed that the bird’s feathers looked more reddish brown than bright red, which supports my belief that he has received a visit from a rufous hummingbird.Ruf-Drawing

I speak from personal experience. My yard has attracted rufous hummingbirds on a couple of occasions. In October of 2016 I received my most recent visit from a rufous hummingbird, which lingered into November and was banded by Mark Armstrong. A former curator of birds for the Knoxville Zoo, Armstrong has devoted several years to studying the phenomenon of rufous hummingbirds that appear to migrate on a regular basis through the eastern United States every fall and early winter. Mark’s efforts have largely focused on Tennessee reports of rufous hummingbirds, but other banders operating from the Gulf Coast to New England have confirmed rufous hummingbirds in their respective regions.

The possibility of attracting a rufous hummingbird is the reason I encourage others to keep a sugar water feeder available into October and November. Experts who have studied the matter note that the presence of a feeder will not encourage ruby-throated hummingbirds to linger. These tiny birds know instinctively when it’s time to depart. Without the attraction of a feeder, however, a visiting rufous hummingbird might reject any extended stay in your yard.

Selasphorus rufus, or the rufous hummingbird, is about the same size as the ruby-throated hummingbird. Both species reach a body length of a little more than three inches and weigh only a few grams. In fact, one of these small hummingbirds might weigh the equivalent of a dime. Female rufous hummingbirds are slightly bigger than males, so a well-fed female rufous hummingbird might weigh as much as a nickel. So, to get an accurate impression of this sort of size, simply think of these tiny birds as weighing less than some of the spare change in your pocket.

Although hummingbirds are not known for their longevity, the website for Tennessee Watchable Wildlife notes that the oldest rufous hummingbird on record reached an age of eight years and 11 months. For the most part, hummingbirds blaze like tiny comets and enjoy typically brief but fast-paced lives. Despite a prevalent impression, hummingbirds are not delicate creatures. For instance, the rufous hummingbird’s tolerance for cold allows it to survive temperatures that dip briefly below zero. This adaptation has allowed the rufous hummingbird to breed as far north as Alaska.

The Selasphorus genus of hummingbirds consists of the rufous and six other species. Of those species, the Allen’s hummingbird, broad-tailed hummingbird and calliope hummingbird are known to also migrate through the eastern United States although with less frequency than the rufous. The remaining Selaphorus hummers — scintillant hummingbird, glow-throated hummingbird and volcano hummingbird — range in the tropical regions of Costa Rica and Panama. Those rufous hummingbirds that don’t spend the fall and early winter in the southeastern United States choose to overwinter in the region of Mexico around the city of Acapulco. This majority of the rufous hummingbird population migrates north again in the spring to claim nesting territory that can range from the Rocky Mountains of the western United States, as well as the Pacific Coast states of California, Oregon and Washington, all the way north to southern Alaska, as well as British Columbia in Canada.

Those rufous hummingbirds that continue to migrate through the southeastern United States each autumn constitute more evidence that we still have a lot to learn about birds. Even an abundant species like the rufous hummingbird offers mysteries that curious humans can attempt to understand.

While I can’t guarantee hummingbirds, I want to remind readers of the bird walks at 8 a.m. each Saturday in October at Sycamore Shoals State Historic Park in Elizabethton, Tennessee. Remaining walks, which are free and open to the public, are scheduled for Oct. 21 and Oct. 28. Meet at the parking lot at the park’s visitors center. Bring binoculars to increase your viewing pleasure.

World’s coffee drinkers owe debt to pest-eating warbler

Do you like to have a morning cup of coffee as you watch the early-bird arrivals at your backyard feeders? If so, you may want to thank some of the warblers and other neotropical migrants that consume tiny insect pests injurious to coffee farms.

The website Coffeehabitat.com provides an archive of interesting reading material about the connections between coffee farming and many neotropical birds. According to a profile on the black-throated blue warbler at the website, this particular warbler has a strong affinity for wintering on coffee farms.

The black-throated blue warbler is a nesting bird in hardwood and mixed forests in many mountainous regions of eastern Tennessee, southwestern Virginia and western North Carolina. In fact, the species nests as far south as northern Georgia along the Appalachian Mountains. Those birds not nesting in the Appalachians make their summer home in southern Canada, as well as northern states like New York and Pennsylvania.

Thanks to scientific tests of the birds’ feathers, scientists now know that most of the black-throated blue warblers that spend the summer nesting season in the Appalachians are in turn wintering in Puerto Rico and Hispaniola. The black-throated blue warblers from the northern part of the range for the species spend the winter months in Cuba and Jamaica.

I’ve been spending more time than usual in my yard since the arrival of September, and I’ve been rewarded with glimpses of numerous migrating warblers, including Tennessee warbler, Blackburnian warbler, Cape May warbler, black-and-white warbler, chestnut-sided warbler, hooded warbler, Northern waterthrush and black-throated green warbler, as well as a dazzling male black-throated blue warbler.

Warbler-InHand

Photo by Jean Potter • A male black-throated blue warbler, banded for a study on songbirds, is examined closely. This is one of the most beautiful of the warblers.

If you recall the 1980s hit song, “Sharp Dressed Man,” by ZZ Top, perhaps I can give an accurate impression of the male black-throated blue warbler. He a dapper, sprightly fellow with a blue topcoat that dominates first impressions. It’s only after seeing the shock of blue that the observer takes notice of the black throat and the black feathers forming a dark facial mask, as well as a clean divide between the bird’s blue crown and back and the clean white underparts. The male even carries a fresh pocket “handkerchief” in the form of a white block on each wing. This becomes a diagnostic mark in the female’s less impressive version.
The sexes of black-throated blue warbler are the most markedly different among all the warblers. Even the famous early naturalist and painter John James Audubon got confused by the black-throated blue warbler male and female. He even made the mistake of painting a young black-throated blue warbler and misidentifying it as “pine swamp warbler.” The female black-throated blue has nary a trace of black in her feathers. Her plumage is mainly a dull olive-gray with dingy white underparts. Her only tie to her mate when it comes to appearance is her much more modest version of the “pocket handkerchief” on each wing.
In Jamaica, black-throated blue warblers are identified by Coffeehabitat.com as the number one predator of the dreaded coffee berry borer. So, as you raise that cup of affordable morning coffee, thank the black-throated blue warbler for eating all of those harmful pests that, left unchecked, would cause coffee prices to spike.

Plovers among migration champions of vast and varied shorebird clan

0815171646c (1)

Photo by Janice Humble • A killdeer wanders in a grassy area near the Wal-Mart on Volunteer Parkway in Bristol. The killdeer, a species of plover, is one of the more common shorebirds found in the region.

I’m always glad to lend a hand at identifying birds. If you’re uncertain of a bird’s identification and have a photo of the bird in question, assistance is an email away. Janice Humble emailed me seeking some help with identifying the bird in a photograph attached with her message. She noted that the bird was accompanied by a companion in the grassy area near the Wal-Mart on Volunteer Parkway in Bristol. She also noted that the two birds uttered loud “peeps” during her observation.

The bird turned out to be a killdeer, a species of plover native to North America. Plovers belong to the family of shorebirds that include various sandpipers, curlews, dowitchers, stilts, avocets and other species. The killdeer is a rather common shorebird that finds itself at home far from the seashore, often present in habitats such as pastures and golf courses, as well as the grassy areas near the concrete and asphalt jungles that surround Wal-Marts and other such shopping complexes.

The killdeer’s famous for its faking of an injured wing. When its nest or young is threatened, a killdeer will go into an elaborate display, fluttering the “injured” wing and uttering shrill peeps to distract the potential predator. If successful, the bird will lure the predator away from the nest or vulnerable young. Once at a safe distance, the killdeer undergoes a miraculous recovery and takes wing, leaving behind a bewildered and perhaps chagrined predator.

Other North American plovers related to the killdeer include American golden-plover, black-bellied plover, Pacific golden plover, Wilson’s plover, piping plover, snowy plover, mountain plover and semipalmated plover. About 70 different species of plovers exist around the world, including such descriptively named birds as little ringed plover, red-capped plover, three-banded plover and white-fronted plover.

Musick’s Campground on Holston Lake has been one of the best area locations for seeking shorebirds during their migrations. The shore near the campground has been a magnet for persuading unusual shorebirds to pause their journey to rest, refresh and refuel. The location’s privately owned, but individual wishing to bird the shoreline can enter by signing the guest book located a small but well-marked kiosk. Some of the most memorable shorebirds I’ve seen at Musick’s Campground over the years include whimbrel, dunlin, sanderling, greater yellowlegs, short-billed dowitcher, American avocet, black-bellied plover and semipalmated plover. In recent weeks, the location has hosted such unexpected shorebirds as red knot and red-necked phalarope.

While the neighboring states of Virginia and North Carolina offer coastal birding opportunities, my native Tennessee remains quite landlocked. This fact poses a challenge for birders looking to capitalize on the seasonal migrations of shorebirds. Fortunately ponds, mudflats on the shorelines of lakes, riverbanks and even flooded fields offer adequate substitute habitat for many shorebirds. While the Mountain Empire region may lack a seashore, migrating shorebirds have learned to make do.

6300749922_099f28ae81_o (1)

Photo by Jean Potter • The American golden-plover, like this individual, is a long-distance migrant among the varied family of shorebirds.

This varied and far-flung family is also known as “wind birds,” a term which is an allusion to the capacity of many species of shorebirds to undertake nothing less than epic migrations. Many of the shorebirds that pass through in the spring are in haste to reach their nesting grounds as far north as the edge of the Arctic tundra. In fall, many of the same birds are eager to return to destinations in Central and South America ahead of cold weather and times of scarcity.

The plovers — the sedentary killdeer excepted — are among the champions of long-distance migration. According to the Audubon website, the black-bellied plover spends the brief summer season nesting in the world’s high Arctic zones but disperses to spend the winter months on the coasts of six of the globe’s seven continents.

The Pacific golden-plover’s twice yearly migrations represent an even more impressive feat. This shorebird often nests in Alaska and winter in Hawaii. The website Phys.org notes that research on this plover has revealed that the bird is capable of flying almost 3,000 miles in a mere four days. The website also reveals that those plovers wintering in Hawaii cannot lay claim to longest migrations. Some Pacific golden-plovers nest even farther south in the Pacific, reaching the Marshall Islands.

Black-belliedPlover

Photo by Jean Potter • A black-bellied plover stands out from most relatives when it wears its nesting season breeding plumage.

Shorebirds represent only a single family of birds migrating through the region in the fall. Songbirds from warblers and thrushes to vireos and flycatchers, as well as raptors and waterfowl, wing their way through the region every fall. Get outdoors with a pair of binoculars and have a look. It’s almost impossible not to see something, which may turn out to be a delightful and unanticipated surprise.

Elizabethton summer bird count sets new record

The Lee and Lois Herndon Chapter of Tennessee Ornithological Society, also known as the Elizabethton Bird Club, conducts two summer surveys of area bird life. Last week, the results of the Unicoi County Summer Bird Count were explored. This week, the focus is on the Carter County Summer Bird Count, which set a new record. The 24th Carter County Summer Bird Count was held Saturday, June 10, under favorable weather conditions with twenty observers in six parties. A record high of 123 species were tallied, besting the previous high of 121 species set in 2013. The average over the previous 23 years was 112 species, ranging from a low of 105 to as many as 121.

Long-time count compiler Rick Knight said highlights of the count included seven Ruffed Grouse, including chicks, as well as such species as Yellow-crowned Night-heron, Bald Eagle, Red-shouldered Hawk and 21 species of warblers.

The American Robin, with 392 individuals counted, barely edged out European Starling, with 389 individuals counted, for most numerous bird on this year’s summer count.

Making the Summer Bird Count for the first time was Red-headed Woodpecker, represented by a pair of birds nesting at Watauga Point Recreation Area on Watauga Lake near Hampton. Other notable songbirds found included Vesper Sparrow, Blue Grosbeak, Red Crossbill and Pine Siskin. I counted birds with Chris Soto, Mary Anna Wheat, and Brookie and Jean Potter at such locations as Wilbur Lake, Holston Mountain and Sycamore Shoals State Historic Park.

I had a recent phone call with Erwin resident Don Dutton, who wanted to know why hummingbirds have been scarce around his home this summer. I’ve noticed fewer hummers at my own home this summer, but it’s natural for numbers to fluctuate from year to year. I anticipate that numbers will rise as hummingbirds begin migrating south again in the coming weeks. At that time, the adult hummers will be joined by the young birds from this season’s successful nesting attempts.

Ruby-throated-WILLOWS

Photo by Bryan Stevens • Numbers of Ruby-throated Hummingbird in the region tend to fluctuate each year, but people should see a spike in their numbers as the hummingbirds end summer nesting and start migrating south again.

Don shared that when he lived out west, he often visited Mount Charleston near Las Vegas, Nevada, where he saw swarms of hummingbirds comprised of various different species. In the eastern United States, the only nesting species is the Ruby-throated Hummingbird.

If you have felt slighted by hummers so far this year, keep a sugar water feeder available to attract them on their way south later this summer and into the fall. To share a sighting, make a comment, or ask a question, send email to ahoodedwarbler@aol.com.

 

 

Writer and artist Julie Zickefoose to share wisdom at Abingdon program, nature walk

 

With the nesting season for some of our favorite birds kicking off, the timing is especially fortuitous for an upcoming program. Acclaimed nature writer and wildlife illustrator Julie Zickefoose will be the a featured speaker for Sunday with Friends at the Washington County Public Library in Abingdon, Virginia, later this month. Her talk will be followed by a book sale and signing.

In addition, Zickefoose will take part in a bird walk along the Virginia Creeper Trail at 8 a.m. on Saturday, April 22. Those wishing to participate in this Earth Day event are invited to meet at the trailhead in downtown Abingdon. I’m planning on attending the walk, which I hope will produce many interesting migrant birds. The walk is free and open to the public.

Zickefoose, the author of the new book, “Baby Birds: An Artist Looks into the Nest,” will speak Sunday, April 23, at 3 p.m. at the Washington County Public Library. Her event is free and will be held in the Conference Room at the Main Library in Abingdon, Virginia.

The public is invited to meet Zickefoose on the day after Earth Day to celebrate her new book. Life-sized baby birds wriggle, crawl and flutter off the pages of this beautiful book, the product of 13 years of deep involvement and close observation of nesting birds. Lively writing describes the development of 17 bird species from egg to fledgling, with the wonder, humor and relentless curiosity that Zickefoose is known for. She provided commentary on National Public Radio’s “All Things Considered” for five years and for 12 years has written a thrice-weekly natural history blog.

She has written several other books, including “The Bluebird Effect: Uncommon Bonds with Common Birds,” “Natural Gardening for Birds: Create a Bird-friendly Habitat in Your Backya26312954._UY1628_SS1628_rd,” and “The Young Birder’s Guide to Birds of North America,” a co-writing venture with Bill Thompson.

 

According to Zickefoose’s website, she began her career as a field biologist for The Nature Conservancy. She became a magazine and book illustrator. Eventually, she began illustrating her own stories. She writes and paints from Indigo Hill, her 80-acre sanctuary in Appalachian Ohio. Zickefoose also writes a blog. To read entries, visit juliezickefoose.blogspot.com.

Ben Jennings helped secure Zickefoose’s lecture. He has worked for the past 15 years organizing “Sunday with Friends,” a series of book and author events hosted by the Washington County Public Library’s Friends of the Library organization.

“I get tips from lots of folks about writers, as well as doing research on my own,” Jennings said.

He also noted that Kate Foreman persuaded him to invite Zickefoose to take part in the series. “Kate is a longtime friend, and currently the director of advancement at Barter Theatre,” Jennings said. “I certainly trust her judgment. Kate had to remind me — but I did remember — Julie’s commentary on NPR several years ago. Julie was thrilled to come to be with Kate for the weekend.”

The Friends of the Washington County Public Library is a voluntary, non-profit organization whose purpose is to help strengthen the resources of the library and to make it a dynamic force in the community. Friends’ activities generally fall into four main categories— advocacy, fundraising, programming and volunteerism. First organized in the mid-1960s, the Friends groups has made an important contribution over the years by helping to raise funds to improve library facilities and providing financial support for special projects. The Washington County Public Library is located at 205 Oak Hill St., Abingdon, Virginia. For more information, visit http://www.wcpl.net.

Bluebird-Box

••••••

A pair of Eastern bluebirds, a species of birds often featured in Zickefoose’s writings, has been exploring the nest box options available at my home. The bluebirds actually started checking the boxes in late February. With the arrival of March, the pair has had to contend with as many as three tree swallow interlopers. I’m not sure of the status of the third tree swallow, but it definitely gives the swallows an edge in numbers.

While bluebirds are not totally loyal to previous nesting locations, studies indicate that as many as 30 percent of bluebirds return to previous nesting sites the following season. So, if you can attract a pair of bluebirds to your yard, that’s half the battle. The same pair, or perhaps some of their offspring, will quite possibly return to yard in future years.

Habitats with spacious areas of short grass are perfect for bluebirds. So, homes with large lawns or that are located adjacent to fields, will attract bluebirds looking for a place to nest. If you lack any trees with natural cavities, a bluebird nesting box is necessary to secure their extended stay. Nesting box plans are easily obtained online if you want to build your own boxes, or you can purchase boxes at many farm supply stores and garden centers.

To keep the bluebirds happy and safe, avoid using herbicides or pesticides on your lawn to prevent accidental poisoning of adult bluebirds and their young. A few small trees and shrubs spaced throughout the yard will provide convenient perches for bluebirds as they hunt for insects to feed themselves and their young.
