Prepare to welcome returning hummingbirds as migrating birds make their way back

Rubythroat-TheSoarNet

These tiny birds must cross the Gulf of Mexico, without stopping, to reach their nesting grounds in the eastern United States. The journey across the Gulf can take them 18 to 22 hours, dependent on weather conditions.

As it has done for many years now, the website journeynorth.org is tracking the progress of ruby-throated hummingbirds as they return to the United States.

Most of the first sightings of hummingbirds made each spring are of male hummingbirds. The males arrive first so they can find and defend a choice territory for the purpose of attracting females. Indeed, there are many more sightings this week for male ruby-throated hummingbirds from Journey North citizen scientists who live along the Gulf Coast states.

On Facebook, I have been doing my own tracking based on posts from friends living farther south. For instance, Marcie McGehee Daniels in Summerville, South Carolina, made a Facebook post on March 22 to share news of her first-of-season ruby-throated hummingbird.

“He drank for a few seconds and then rested in the shade for about 10 minutes, worn out from his trip!” Marcie posted on her Facebook page. She also posted a fantastic photo of the intrepid migrant.

As demonstrated by Marcie’s post, the migration of ruby-throated hummingbirds is drawing closer to our region. They cross the Gulf of Mexico without stopping to reach the Gulf States. Once they make that difficult flight, they will spend some time recuperating before they spread out to make their way northward. Residents in Virginia, Tennessee and North Carolina should soon be making their first sightings of ruby-throated hummingbirds since these tiny flying gems departed last October.

On a recent visit to Fripp Island, South Carolina, I didn’t see any ruby-throated hummingbirds, but I did observe other birds that reminded me that many of my favorite birds should be returning to my home within the next few weeks. I enjoyed sightings of several species of warblers, as well as various shorebirds. Many warblers return to the region in April, and shorebirds may make migration stops at area lakes and rivers as they push rapidly toward breeding grounds in regions far to the north in Canada and Alaska.

Some of the first of the resident summer birds to return to the region each year includes species such as Louisiana waterthrush, brown thrasher, chipping sparrow, tree swallow and blue-gray gnatcatcher. Not too long after these “early birds” have returned, people can expect to start seeing the vanguard of the ruby-throated hummingbird spring migration as these tiny birds, which weigh no more than a nickel, return to their summer nesting grounds across the eastern United States and Canada.

As one might imagine, such tiny birds face a range of threats. In addition to offering sugar water feeders and planting gardens with nectar-bearing plants, there are other ways to help ruby-throated hummingbirds thrive.

The American Bird Conservancy recommends paying attention to our buying habits. In the winter months when they are far from their summer homes, ruby-throated hummingbirds are known to winter on shade coffee farms. Unlike today’s typical “sun” coffee farm, which razes all trees but the coffee itself, these traditional farms grow coffee in the shade of native trees. By doing so, they produce superior coffee and provide habitat for dozens of migratory songbirds, according to the ABC.

The importance of shade coffee for migratory birds was confirmed by naturalists Kenn and Kim Kaufman, who estimated that a single shade coffee farm in Nicaragua sheltered more than 1,200 migratory bird species—including the ruby-throated hummingbird—on just 90 acres. The ABC notes that buying bird-friendly coffee is an easy way people can help hummingbirds and many other migratory birds.

While the eastern United States is home only to the ruby-throated hummingbird as a nesting hummingbird species, the western half of the United States and Canada can claim about a dozen nesting species, including rufous hummingbird, Allen’s hummingbird, Anna’s hummingbird, broad-tailed hummingbird, black-chinned hummingbird, calliope hummingbird, buff-bellied hummingbird, broad-billed hummingbird and violet-crowned hummingbird.

To track the progress of ruby-throated hummingbird migration for yourself, visit http://www.journeynorth.org to monitor their approach to our region. Ruby-throats typically arrive in our region in early April. The early date for a ruby-throated hummingbird arrival in 2018 took place on April 4. If you don’t have your feeders outdoors and waiting for them, it’s time to do so.

As always, I love to hear from readers about their first hummingbird sighting of the year. Jot down the time and date and contact me by email at ahoodedwarbler@aol.com. You can also report your sightings on Facebook at http://www.facebook.com/ahoodedwarbler. I can hardly wait for one of our favorite birds to get back. Let’s give them a hearty welcome.

The world can be a big, bad place for tiny hummingbirds

Mantis-Four

Many years ago I read an account of a scarlet tanager making a snack of a ruby-throated hummingbird. Memory being what it is, I am no longer sure if that account was corroborated or one of those urban legends of birding.

A few pertinent facts should be considered. Male scarlet tanagers look striking in their red and black plumage. Ruby-throated hummingbirds are attracted to the color red. In the details I recall of the story about the predatory tanager, the hummingbird kept flying close to the tanager as if attracted to the red plumage. If so, it was a case of curiosity kills the cat or, in this case, the hummingbird. The tanager seized the hummingbird in its bill and, for good measure and to “tenderize” its prey, beat the hummingbird against the side of a branch. All of this took place before a crowd of birders who observed the incident through their binoculars. I don’t recall anyone taking a photo of the hummingbird’s tragic demise.

An email from Gene Counts reminded me of the tale of the tanager and the hummingbird. Gene, who lives in Haysi, Virginia, sent me a photograph and a short note about a praying mantis that stalks hummingbirds as they visit his feeders for a sip of sugar water.

MantisVsHummer

Photo by Gene Counts • This photo was shared by Gene Counts, who described how the mantis stalked hummingbirds that came to his feeder.

Gene told me of his excitement upon capturing the large insect’s behavior in a photograph.

“I just had to share this picture with you,” Gene wrote. “After all, my wife, Judy, was more excited today than the day we married in Chicago 54 years ago.”

He certainly hooked my attention with that introduction.

“A praying mantis is using our feeder as his own private hunting preserve,” Gene continued in his email. “The mantis follows and stalks the hummingbirds all the way around 360 degrees.”

So far, the stalking has only resulted in “several near misses,” but Gene declared that he is ready to pounce in case the mantis gets lucky.

“It has been four hours and he has lowered his goal,” Gene wrote of the patient mantis. “He is now clinging to the bottom (of the feeder) waiting for an insect. Now I can expel my breath as he no longer an avian threat.”

While Gene’s mantis may not be an immediate threat to hummingbirds visiting his yard in Haysi, does that mean we can be complacent when these large insects share our yards and gardens with hummingbirds?

Documented evidence exists to identify large praying mantises as predators on ruby-throated hummingbirds. A brief foray online found numerous instances of hummers falling victims to these large carnivorous insects.

There are two species of mantises in the region — the European, or praying mantis, and the Chinese mantis — capable of capturing hummingbirds. Both species were introduced in the 1800s to act as a predator of insect pests detrimental to crops and gardens. The Chinese mantis can reach a length of 4.3 inches, while the European mantis achieves a length of about 3.5 inches. A third species — Carolina mantis — reaches only a length of 2.5 inches and should not pose a threat to ruby-throated hummingbirds, which are about 3.5 inches long.

Although introduced from Europe, the European mantis (Mantis religiosa) has earned recognition as the official state insect of Connecticut. The native Carolina mantis is the official state insect for South Carolina.

In Central and South America, where the world’s more than 300 species of hummingbirds reach their greatest diversity, there are also more species of predatory mantises. Some of these tropical insects prey on the tropical counterparts to the ruby-throated hummingbird.

Consider the way the mantis makes a perfect predator. It’s spiky forelimbs are spiky and serrated, making them perfect for seizing and grasping. This insect’s triangular head can turn their heads 180 degrees to scan its surroundings with two large compound eyes. A mantis also has three other simple eyes to increase its keen vision. Brutal mouthparts can easily tear apart and devour any prey the mantis manages to catch with its ambush hunting style.

Hummingbirds, regardless of species, are in a tough spot in the food chain. A bird not much bigger than many large insects is going to be a target for opportunistic predators like a mantis that will attempt to kill and consume anything small enough for them to make the effort.

Maria Sibylla Merian, a German-born naturalist and scientific illustrator, was one of the first naturalists to observe insects directly. She painted this horrific work featuring a large spider preying on a hummingbird that had been dutifully incubating her eggs. When she died in 1717, she was recognized as one of the world’s foremost entomologists.

To make matters worse for ruby-throated hummingbirds, some large spiders and the bigger dragonflies have also been documented as hummingbird predators. When ruby-throated hummingbirds retreat to Central America for the winter months, they also face threats from lizards and snakes.

The list of predators that have been known to eat ruby-throated hummingbirds extends to bullfrogs, as well as many raptors, including kestrels, merlins and sharp-shinned hawks. Blue jays and other birds will raid hummingbird nests for eggs or young. Squirrels and chipmunks are also nest predators.

Despite all these perils, some ruby-throated hummingbirds have achieved a “long” life. The oldest on record was a ruby-throated hummingbird banded at the age of nine years and one month. Most elder hummingbirds are females. Few male hummingbirds, perhaps because of the energy they expend dueling with each other, reach their fifth birthday.

It’s definitely not easy being as tiny as a hummingbird in a world of fearsome giants, but birders who have seen a hummingbird hover boldly in front of their faces know how these tiny birds take life in stride. They may have a disadvantage in size, but that doesn’t keep them from living life as if they were as big as an eagle.

Birds deploy amazing strategies for nest construction

I received a letter from Wayne and Dot Ballard sharing information about an ingenious but unexpected roosting location they provided for a wren at their home in Marion, North Carolina.

Wayne found the an old bird’s nest attached to the limb of a cedar tree. Dot tied a piece of twine around the ends of the limb and let it hang from a hook under the eave of their porch.

A few days later, the limb and nest attracted the notice of a Carolina wren. The bird, finding this snug nest in a convenient location, adopted it as a nighttime roost. “We watched, and every evening just as the sun was setting, a wren came and set on the porch swing and then hopped right up into the nest, head first,” Dot wrote. “This continued every evening for six or seven weeks, with its arrival times adjusted as the days got shorter.”The couple couldn’t verify if their observation involved the same bird nightly, but I suspect it did. “With its head stuck into the nest, it must have rested pretty good,” Dot said. “My husband said he had seen it leave when he got up early in the morning.”

Wayne and Dot felt fortunate to enjoy this peek into the wren’s life. “We always enjoy God’s nature, especially when we are allowed to witness it so close,” Dot wrote.

The couple did ask if I thought the nest had been built by wrens. I believe that, although a Carolina wren adopted the nest for its roost, another species of bird probably built the nest. The photos the Ballards enclosed with their letter show a cup-shaped nest of the sort that might have been built by a sparrow or warbler.

Their letter persuaded me to explore some of the unusual ways some of our feathered friends go about creating a nest, or home, for their young. The ingenuity of some birds in building a nest is quite remarkable.

The majority of our common backyard birds build the familiar “cup-shaped” nest that is tucked away in a shrub or the fork of a tree. Birds that build nests in such a fashion include everything from blue-grey gnatcatchers and scarlet tanagers to indigo buntings and American goldfinches.

Other birds, such as Eastern bluebirds and tree swallows, accept human-provided nesting boxes. In the past, these birds relied on natural cavities, such as a rotten knothole in a tree’s trunk or a weathered fence post that had gone hollow. Many cavity-nesting birds do not or cannot excavate their own cavities. Some birds are better equipped to excavate their own cavities or burrows in everything from tree trunks to river banks. Cavity-nesting offers an added degree of protection in comparison with an exposed and vulnerable cup nest tucked in a hedge or dense shrub. Some birds, however, have taken cavity-nesting practices to the extreme.

For instance, the female great hornbill builds her nest in the hollow centers of large tree trunks, and the opening is sealed with a plaster made up mainly of mud, droppings and fruit pulp. She remains imprisoned in her nest until the chicks are semi- developed, relying on the male to bring her food. During this period the female undergoes a complete molt. The young squabs are devoid of feathers and appear very plump. She is fed by her mate through a slit in the seal. The clutch consists of one or two eggs she incubates for 38-40 days. Once the female emerges out of the nest, it is sealed again by the chicks. In some species, the young depart with their mother, and are tended outside of the former nesting cavity by both parents. The great hornbill resides in the forests of India, the Malay Peninsula and Sumatra, Indonesia. There are about 55 species in the hornbill family, which ranges through Africa, Asia and some of the islands of Melanesia.

Megapodes — also known as “incubator birds” or “mound-builders” — do not incubate their eggs with their body heat as other birds do, but bury them. Their eggs are unique in having a large yolk, making up 50-70 percent of the weight of the egg. They are best known for building massive nest-mounds of heat-producing, decaying vegetation, which the male attends, adding or removing litter to regulate the internal heat while the eggs hatch.

This method of incubation is something practiced by some reptiles, including crocodiles and alligators, but it is definitely unusual among birds. Once hatched, young birds are fully feathered and active, already able to fly and live without any care or assistance from their parents.

Wrens are known to nest and roost in some unusual places, as shown in this painting of wrens nesting in an old hat by artist John James Audubon.

Two of the better-known species, both from Australia, are the malleefowl and the Australian brush-turkey. There are about 20 species of birds classified as Megapodes, and they are concentrated in the Australasian region, including islands in the western Pacific, Australia, New Guinea and the islands of Indonesia east of the Wallace Line. They also occur on the Andaman and Nicobar Islands in the Bay of Bengal.

The white tern is a small seabird found across the tropical oceans of the world. Although other terns build nests, the White Tern no longer bothers to construct even a rudimentary nest. Instead, the female lays a single egg on bare branches or in a small fork in a tree. Nothing else is added to the location where the egg is deposited.

The behavior is not typical of terns, which generally nest on the ground and construct the nest of such materials as shells or other debris.

Of course, both the eggs and chicks of white terns are vulnerable to becoming dislodged by heavy winds. Newly-hatched chicks have well developed feet they use to hang on to their precarious nesting site.

The sparrow-sized sociable weaver (Philetairus socius) of Africa enjoys company, which explains how and why such a small bird constructs a huge nest. Actually, many of these birds working together construct a huge structure — sometimes described as similar to a bale of hay — that hangs from sturdy trees and other tall structures. Such a “compound nest” is rather rare among birds.

The communal nests built by sociable weavers can house 100 pairs of birds and are quite spectacular. They are also considered the largest bird-built structures in the world. Other birds also benefit from these huge structures, which are built mostly of grass and sticks. Other species of the Ploceidae, or weavers, also build communal nests, but their efforts are not quite as impressive as those constructed by the sociable weaver. Other small birds may also nest or roost in the structure, and large birds, such as vultures, have been known to build their own nests on top of these compound nests.

In nature, nothing gets wasted. A Carolina wren using another bird’s used nest is not all that rare. These birds are fond of a cozy nook. If they can find one ready-made, it’s all the better.

Hummingbirds are back, and readers share first spring sightings

Photo by Bryan Stevens • Ruby-throated hummingbirds returned to the region earlier this month. This male, sipping sugar water from a feeder, shows its namesake red throat patch.

As many readers have already noticed, the ruby-throated hummingbirds are back. These tiny flying gems began returning to the region in the first days of April, but reports of their arrival spiked during the second week of April.

What do the hummingbirds that make their homes in our yards from April to October do during the five months they are absent from the region?

Most ruby-throated hummingbirds retreat to southern Mexico and Central America, some winging their way as far south as extreme western Panama, as well as the West Indies and southern Florida. They utilize a variety of habitats, ranging from citrus groves and forest edges to tropical deciduous forests and the edges of rivers and wetlands.

Those ruby-throated hummingbirds that make it as far south as Panama may find that they must compete with 59 other species of hummingbirds that call the Central America country home. In their winter home, the ruby-throated hummingbirds are definitely just another face in the crowd when its comes to their kin. In Panama, a ruby-throated hummingbird might encounter violet-headed hummingbirds, white-necked jacobins, black-throated mangos and green violet ears.

It must be nice to live among so many hummingbirds. Closer to home, the ruby-throated hummingbird is the only one of its kind to nest in the eastern United States. Some of the ones arriving at our feeders now will speed their way farther north, but some will settle in our yards and gardens as they bring forth the next generation of ruby-throated hummingbirds.

Dianne Draper reported the earliest observation of which I am aware. A friend on Facebook and a fellow birder, Dianne posted that the first hummingbird of spring arrived at her home in Jonesborough, Tennessee, on the morning of April 4. Her sighting was seven days earlier than any of the others I received.

Harold and Elizabeth Willis in Marion, North Carolina, reported their first hummingbird at 5 p.m. on Wednesday, April 11.

Helen Whited in Richland, Virginia, saw her first hummingbird at 12:40 p.m. on Thursday, April 12.

Judy and Bill Beckman saw their first spring hummer at 7:25 p.m. on April 12 at their home in Unicoi, Tennessee.

Lois Wilhelm, who lives on Little Bald Creek Road on Spivey Mountain in Erwin, Tennessee, saw her first hummingbird of 2018 at 3:30 p.m. on April 12.

Glen Eller in Kingsport, Tennessee, saw his first spring hummingbird around 5 p.m. on April 12. The bird — a male — drank for about four minutes. “I guess he needed a good fill up,” Glen commented.

Nola Martin from Nebo, North Carolina, reported her first hummer arrived just before 11 a.m. on April 12.

“He was a little green bird….not sure which kind or which sex,” she wrote in her email. “It certainly remembered where one of my feeders was last year, though, as it was looking for it in that spot, I didn’t have that one out yet.”

Nola said she now has five of her seven feeders filled and placed out for the returning hummingbirds.

Betty Poole saw her first male hummingbird of spring when the bird arrived at 9:05 a.m. on Friday, April 13, at her home in Bristol, Virginia. Her daughter, Jane P. Arnold, emailed me the information about her mother’s sighting. Jane is still awaiting her own first spring sighting of a hummingbird.

Debbie Oliver, while watching Wheel of Fortune on the evening of April 12, got her first glimpse of a spring hummer at her deck feeders in Bristol, Tennessee.

“I couldn’t observe if it was male or female due to the dimming light,” she wrote in an email.

“It was a curious ruby-throated hummingbird just flying around the feeder without taking a sip of nectar,” she added.  Around 9 a.m. the following morning, she spotted a male ruby-throated hummer drinking nectar at the feeder.

She speculated about whether the bird was the same individual that visited the previous evening. “We’ll never know,” she decided.

Joneen Sargent emailed me to let me know that her husband, Dale, saw a ruby-throated hummingbird on April 12 at 7 a.m. The Sargents live off of Booher Drive in Bristol, Tennessee.

Bob Cheers of Bristol, Virginia, saw his first ruby-throated hummingbird at 6:45 a.m. on April 13. Bob keeps a record of the arrival dates for this tiny bird. In 2015, he saw the first hummer on April 9. Last year, he saw his first hummer on April 11. In 2016, the first bird arrived on April 13. In 2014, he had to wait until April 14 to see the first hummer of spring.

Mark Hurt, who lives on Glenway Avenue in Bristol near Virginia High School, said that his “little buddy,” the ruby-throated hummingbird, returned about 1 p.m. on April 13.

Sandra Loving reported that her first hummer sighting took place at 6:17 p.m. on April 13 at South Holston Lake in Tennessee.

Peggy Oliver saw her first male ruby-throated hummingbird of spring at 6:15 p.m. on April 13.

Ashley Russ of Abingdon, Virginia, emailed me to share that she spotted her first hummingbird of the season at 7:20 p.m. on April 13.

Terry Fletcher saw her first male ruby-throated hummingbird at her feeder at 6:50 a.m. on April 14 at home in the First Colony subdivision in Bristol, Tennessee. Away from home the previous day, Terry was told by a next-door neighbor that the hummingbirds actually showed up on April 13.

Janice Denton, who lives on Canthook Hill Road in Bristol, Tennessee, emailed me news of her first sighting.

“I’m excited to let you know that I saw my first ruby-throated hummingbird on Friday, April 13,” she wrote. “I have had my feeders out for about two weeks and was sitting on my front porch in the afternoon hoping to see a hummingbird.”

On April 15 around noon, Janice also reported that she saw a male ruby-throated on a feeder outside her kitchen window, and another one came along and chased it off.  “I hope they all stick around for the summer,” she wrote.

Lynne Reinhard reported via Facebook that she had her first hummingbird sighting at her home on the upper end of South Holston Lake on April 14. She noted that the hummingbird arrived a day earlier than last spring.

Linda Sproles, who lives on Hunter Hills Circle in Bristol, Tennessee, observed the first arrival of a hummingbird at her deck feeder at 10:43 a.m. on April 14. “It was a female, I believe, because it did not have a red throat patch,” she added.

Kathy Maggio, who lives between Benhams and Mendota in Washington County, Virginia, spotted her first hummingbird of spring at 1:15 p.m. on April 14.

Phyllis Moore of Bristol, Virginia, saw her first ruby-throated hummingbird of the spring at 4 p.m. on April 14.

Pat Stakely Cook, who resides in Marion, North Carolina, reported two ruby-throated hummingbirds at her feeders on April 14. The two male hummers stayed busy feeding and chasing each other.

Ginger Wertz-Justis in Baileyton, Tennessee, saw a male hummingbird at 6:30 p.m. on April 14.

Richard Trinkle emailed me to report that he saw a male ruby-throated hummingbird at 6:15 p.m. on April 14 at his Bristol home near Friendship Ford.

Robin Small saw the first hummer at 6:15 p.m. on April 14. “As I was looking at the snow falling and the cardinals, woodpeckers and regular visitors to my deck feeders, I saw my first hummingbird of 2018,” Robin wrote in an email. Robin put the feeder out the previous day when temperatures had been in the 80s and added that the hummer visited several times as the snow fell the evening of its arrival.

Janice Humble, who lives near South Holston Lake, put out her feeder on April 14. “It wasn’t 15 minutes until I had a hummingbird,” she wrote in her email.  “I saw two others that same evening.”

Lewis Spicer of Abingdon, Virginia, had both a male and female hummingbird visit his home for the first time this spring on the same day on April 15. He saw the male at 9:35 a.m. The female hummer arrived during afternoon rain at 12:45.

Frank and Myra Renault of Abingdon, Virginia, saw their first hummingbird of spring — a female — at 12:06 p.m. on April 16.

Sheila Myers, who lives on Porter Valley Road in Marion, Virginia, saw her first hummer at noon on April 16.

Rhonda Eller in Chilhowie, Virginia, saw her first spring hummingbird at 4:53 p.m. on April 18.

I am pleased to report that my own first hummingbird sighting for 2018 took place when a feisty male zipped into the yard while I was seated on the front porch. He sipped at four different feeders before he zoomed off. He arrived at 5:40 p.m. on April 14, one day earlier than last year’s first arrival. My feeders had been waiting for the arrival of hummingbirds for about a week when he first appeared.

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.

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.

 

 

Woman gets glimpse into life of a nesting ruby-throated hummingbird

For Bluff City, Tennessee, resident Donna Ottinger, the show in her front yard beats anything you might find on television this summer. Since late July, Donna has been watching a female ruby-throated hummingbird that she has named Bliss carry out her nesting duties.

Like all female ruby-throated hummingbirds, Bliss produced two eggs for containment in a delicate nest of spiderweb, lichen and plant fibers woven onto a maple tree branch. There are some reasons why it’s always a pair of eggs for hummingbirds. First, the nest is so small — about the size of a walnut half-shell — that there is barely room for two eggs, let alone more. Second, once the young hatch, the nest has just enough room to accommodate them as they grow, fed well by their mother. Third, feeding two hungry young hummingbirds is a demanding task. A female hummingbird has to find enough food to fuel her own body and help her young in the nest grow and thrive. It’s a full-time job during the daylight hours. She’s pressed hard to succeed at raising two young. Attempting to rear more would most likely prove impossible.

Donna compared the two tiny eggs to Tic Tac mints. The entire process — from building the nest to incubating eggs to tending hatchlings — requires a commitment of more than two months. Donna noted that even after the young hummingbirds hatched, Bliss continued to reinforce the nest with collected silk from spider webs.

Donna kept the nest under observation after she discovered it in late July. As she noted on her Facebook page, finding a hummingbird nest is not an everyday occurrence. The nest is on one of the lower branches of a large maple tree in her front yard only a short distance from her porch. She was able to sit comfortably while watching Bliss come and go to her tiny nest.

“It’s been a real blessing,” Donna told me when we met in person on Aug. 19. She was gracious enough to permit my mom and me to sit on her front porch and enjoy the show. During our visit, we got to watch as Bliss arrived to feed the babies. It’s not a spectacle for the squeamish. Bliss plunged her long bill deep into the throats of each baby bird in turn and pumped some nutritious contents into the growing youngsters. Despite the fact that it looked like she could easily impale the babies, they suffered no ill effects and looked quite full and satisfied after the visit.

The two babies were hatched on Aug. 1 and Aug. 2, respectively. The staggered hatching reflects the fact that Bliss also laid the eggs on separate days. Not knowing the gender of the babies, Donna named the Aug. 1 hatchling Monday for the day of the week hatching took place. In turn, the second baby, which escaped its shell on Aug. 2, was named Tuesday.

Once hatched, young hummingbirds remain in the nest about 28 days (nearly a month) and depend on their mother to bring them regular meals. If that’s not enough, the ruby-throated hummingbird is known to nest twice in a season. It certainly must rank a female hummingbird as one of the busiest of our summer birds. At the time I wrote this column, Monday and Tuesday had still not left the nest.

The young hummers have grown at an astonishing rate and Donna has witnessed their progress day by day. She noted that young hummers start off life with a short bill. Like the rest of their bodies, however, their bills have grown accordingly as Monday and Tuesday received regular feedings from Bliss.

Female hummingbirds receive no assistance from their mates. Males don’t assist with the rearing of their own young. For male hummingbirds, summer is mainly a time to thrive on the abundance of nectar-bearing blooms, as well as a profusion of tiny insects and spiders that also make up a good portion of their diet.

When I saw them, I knew that little Monday and Tuesday would be out of the nest in a short time. It would also be necessary for them to soon begin fall migration. On Aug. 23, Donna reported on her Facebook page that the young hummers had left the nest.

“Just three weeks after hatching, the baby hummers have both left the nest,” she wrote in her post. “They didn’t go far, and Bliss is still feeding them in a nearby tree where they have taken up new residence.”

The next generation of hummingbirds always helps swell the number of these tiny birds in our yards in late summer and early fall. Keeping visiting ruby-throated hummingbirds can be as simple as planting an abundance of the flowers they love, but offering multiple sugar water feeders also helps. Keep the sugar water mix at a four parts water to one part sugar ratio. Don’t offer honey in your feeders. When mixed with water, it can spoil and spread fungal diseases. Remember that hummingbirds don’t subsist on sugar water alone. They also eat numerous tiny insects and spiders to obtain the protein they need for their dietary needs, so don’t use insecticides near feeders or flowers that hummers are likely to visit.

It was absolutely wondrous to observe Bliss and her babies. The experience has motivated me to keep a closer watch on the hummingbirds in my yard. There are female hummers present every summer. They have to be nesting somewhere, and I’d like to find a nest in my own yard.
