It’s time to start thinking about bringing the hummingbird feeders out of storage. These little winged favorites should be returning to yards across the eastern United States and Canada in the upcoming weeks. In fact, in some locations they’re already back.

I usually hang out my own feeders the first week of April, but I often have to wait a week or two before I finally get a visiting hummingbird. About the earliest I have ever known hummingbirds to get back is the first week of April. The dates around April 8 to April 10 seem a popular arrival date. For some people, however, it may be mid or even late April before they see one.

You definitely increase your chances if you just have a feeder available with a fresh mixture of one part sugar to four parts water. This is the formula that closely matches the sweetness of nectar available from flowers.

There’s always a temporary surge in the numbers of Ruby-throated Hummingbirds from mid-April to mid-May as many of these small winged wonders migrate through Northeast Tennessee. Many of these early arrivals are making only temporary stops at our feeders or in our gardens. The majority of them probably continue to travel farther north to spend the summer.

Just to reach the United States, these tiny birds undertake an arduous journey. They leave their wintering grounds in Central America to return to the United States and Canada for the nesting season. Most of these tiny birds, which are barely four inches long, make a non-stop flight of more than 500 miles across the Gulf of Mexico. The journey can take almost an entire day!

By May, the spring hummingbird migration is basically finished for the region. A few of the female hummingbirds, finding our yards to their liking, will conclude their epic journey here and spend the next few months tending to a new generation of hummers.

She lays two eggs. There are some reasons why it’s always a pair of eggs. First, the nest is so small 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.

The entire process —€” from building the nest to incubating eggs to tending hatchlings —€” requires a commitment of more than two months. The female hummingbird builds her exquisite nest from lichen and various plant fibers, much of it held together by collected spider silk.

Ruby-OneSpot

Once that time-consuming task is completed, the female hummingbird lays her eggs. She will spend about the next 18 days incubating them. Once they hatch, the young will 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.

Of course, a few adult males will end their migration in the region. The males, however, 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.

If all goes well —€” and that’s not the case always, unfortunately — a new generation of hummingbirds may join the adults at feeders in late summer and early fall as a second wave of migration begins. Not surprisingly, hummingbirds face an assortment of predators that can prove detrimental to nesting success. Even prolonged periods of rain or cold weather can produce unfortunate consequences.

Nevertheless, these tiny birds manage to replenish the population each year, ensuring that they will be back in future spring seasons to delight and entertain hosts who have missed them through the bleak months of winter.

I want to close this week’s column by asking for help from readers. I love to document the yearly arrival of ruby-throated hummingbirds. I’d appreciate hearing from any readers who would like to share the information about their first hummingbird sighting of the season. Simply send me your name and location, as well as the date and time when your first hummingbird arrived. The best way to contact me is by my email at ahoodedwarbler@aol.com. Messages are also welcome through my Facebook account at http://www.facebook.com/ahoodedwarbler.

I’ll post the arrival dates I receive in upcoming columns this spring. This is a tradition I have enjoyed observing for years, and I hope all the hummingbird fans out there will participate.

I know I can’t wait for them to be back. I’m looking forward to hosting them again for another six to seven months before they once again depart this coming October to spend the winter in the tropics.

Annual Great Backyard Bird Count provides global snapshot of birdlife

Hunt-Redwing

Photo by Bryan Stevens                                  Red-winged Blackbirds, such as this individual, were counted by many U.S. participants during last month’s Great Backyard Bird Count.

The 2015 Great Backyard Bird Count is now history. Participants were permitted to submit reports through Feb. 28. Although tabulations are still being processed, a great deal of data is already available. By all indications, this annual survey of bird populations enjoyed great success in 2015.

In Tennessee, 139 species of birds was reported on a total of 2,687 checklists. In Virginia, participants turned in 4,672 checklists and found an amazing total of 180 species. Of course, one reason that Virginia enjoys more species is the fact that Virginia offers coastal birding opportunities unavailable in the landlocked Volunteer State.TENNESSEE

Nationwide, 671 species of birds were reported on this year’s GBBC, which received a total of 108,387 submitted checklists.

California took top honors with 376 species of birds found for this year’s GBBC. The Top 10 states for most species, in descending order, included Texas (366), Florida (309), Arizona (273), Washington (231), Oregon (225), New Mexico (215), Louisiana (212), South Carolina (211) and North Carolina (201).

Two_Nene_Geese_Hawaiian_Species

Photo by U.S. Fish & Wildlife Service/Mike Boylan   Many native species, such as the Nene, or Hawaiian Goose, were among those Hawaiian species found in Hawaii by GBBC participants.

North Carolina ranked 10th on the list for states with most species of birds reported. Virginia ranked 12th on the list for states with most species of birds reported. Tennessee managed a 25th place ranking. In last place among the states was North Dakota, with only 62 species reported.

From Alaska came 417 checklists for a total of 122 species of birds. The 225 checklists from Hawaii outnumbered the 93 species of birds found. I was pleased that some of the birds on the list included native Hawaiian species, including the Hawaiʻi ʻamakihi, Hawaiʻi ʻelepaio, ʻapapane, ʻiʻiwi, Hawaiian hawk, Hawaiian coot, Hawaiian goose, or nēnē, and Hawaiian thrush, or ‘Ōma’o, as well as the Hawaii creeper and ʻAkepa, both of which are endangered species.

Returning closer to home, birders in Virginia and Tennessee found some very good birds during the four-day survey.

Roughlegged_Hawk

Photo by U.S. Fish & Wildlife Service                      Rough-legged Hawks, which are strictly winter residents for most of the continental United States, were among the many species found by U.S. participants in the annual GBBC.

Some of the more unusual birds reported in Virginia included common redpoll, rough-legged hawk, Western tanager, Baltimore oriole, cackling goose, Eurasian wigeon, harlequin duck, painted bunting and clay-colored sparrow.

Some surprise birds on the Tennessee checklists included ruby-throated hummingbird, cackling goose, Eurasian wigeon, whooping crane, Pacific loon, Iceland gull, common gallinule, Western grebe, evening grosbeak and brown-headed nuthatch.

Because the GBBC is now a global event, I also explored the data to see how the United States fared in comparison to some other countries. Worldwide, 5,090 species were found and 147,265 checklists were submitted.

In India, 717 species of birds were reported on 6,810 submitted checklists. In South Africa, only 38 checklists were submitted, but these accounted for 347 species of birds. In Kenya, only 21 checklists were submitted, but a total of 326 species of birds was reported.

Evening_Grosbeak

Photo by U.S. Fish & Wildlife Service Songbirds, such as this Evening Grosbeak, showed up in both Canada and the United States during the four-day GBBC.

As for our neighbor to the north, Canadians turned in 10,491 checklists for a total of 241 species of birds. South of the border, 653 species were reported in Mexico on a total of 425 checklists.

Across the pond, 138 species were found in England on a mere 89 submitted checklists.

The GBBC has not, evidently, caught on yet in China where only 20 species were reported on a total of four checklists. The birders submitting the checklists, based on their names, were not native to China. They were probably visitors to China and their visit happened to coincide with the dates of the GBBC.

Three birders in Iran turned in checklists. Based on their names, they were Iranian and did a good job finding 69 species, including Imperial Eagle, Dalmatian Pelican and Greater Flamingo. In Israel, 19 submitted checklists produced a total of 114 species.

In South America, several countries produced impressive numbers of species. In Brazil, the 45 checklists submitted accounted for 502 species. The 69 checklists from Argentina represented a total of 362 species of birds. In Peru, a total of 36 checklists produced 259 species. The 109 checklists submitted from Chile resulted in 205 species for that southernmost nation in South America.

Perhaps not surprisingly, no reports came from such troubled global locations as Iraq, Syria, Libya and Somalia.

Purples

Photo by Bryan Stevens                          Purple Finches were among the species found in the Volunteer State during the Great Backyard Bird Count.

During this year’s GBBC, I counted birds mostly at home due to the heavy snowfall that fell during the first days of the survey. The silver lining, of course, was that the snow and cold brought an increased number of birds to my feeders, including such species as pine siskin, purple finch, Northern flicker, Eastern towhee and Carolina wren.

I’ve had almost as much fun exploring the results from the GBBC as I did taking part in the survey. If you would like to take a look at the results, visit http://www.birdsource.org and investigate the tallies from around the globe at this very interactive website.

Heavy snow forces fox sparrows to abandon reclusive habits

FoxSparrow-Foot

Photo by Bryan Stevens                                                                A Fox Sparrow lifts one foot into its belly feathers on a cold morning in reaction to bitter cold.The cold weather that closed out the month of February in the region also marked a shift in the seasons. The frigid temperatures, snow and ice also brought increased traffic to feeders.

One of the recent new arrivals at my home during the last of the February storms was a fox sparrow, who fed along with such birds as purple finches, pine siskins, American goldfinches and dark-eyed juncos.

In North America, the sparrows are classified in the Emberizidae family, which also includes the buntings, cardinals, grosbeaks and tanagers. The American, or New World, sparrows are a diverse group of seed-eating songbirds with conical bills. Many of them are brown or gray in color, leading to the term “little brown birds” being used to describe a family of similar birds. On closer study, each species of sparrow is quite unique, with many of them having distinctive head patterns or splashes of color apart from the dull browns and grays.

Fox-Bryan

Photo by Bryan Stevens                                                                  Fox Sparrows prefer to remain in thickets and tangle of thick cover. Heavy snows will often bring this sparrow to backyard feeders.

Although they share the name “sparrow,” American sparrows are more closely related to Old World buntings than they are to the Old World sparrows. In fact, the only true Old World sparrow in Northeast Tennessee is the House Sparrow, which was introduced to the United States and is not a native bird.

Although the label “little brown birds” is somewhat accurate for sparrows, learning to distinguish most of the more common sparrows isn’t that difficult. Observing those sparrows that visit feeders is a good place to start. Other sparrows that will come to feeders include song sparrow, field sparrow, chipping sparrow, white-throated sparrow and white-crowned sparrow. The dark-eyed junco and Eastern towhee are also members of the sparrow family, but their common names do not include the term “sparrow.”

Worldwide, there are many superstitions connected with birds commonly known as “sparrows.” In the book The Folklore of Birds, author Laura C. Martin notes that in China the sparrow is a foreteller of good luck. She also points out that in Japan the sparrow is a symbol for gentleness, gratitude and joy.

Keep in mind, however, that sparrows in Japan and China are not among the same family of birds known as sparrows that are found in the United States. In fact, with a few exceptions, our native sparrows are unique to North America.

Photo by U.S. Fish & Wildlife Service                                             A Fox Sparrow perches on a bare branch. These large sparrows are only winter visitors in Northeast Tennessee.

For instance, the fox sparrow is a large, plump bird that in many parts of North America is most familiar as a migrant or wintering bird. The fox sparrow has a rusty tail and a streaked breast, evocative of a fox, hence its common name. Its plumage is dominated by brick-red and gray feathers.

In addition to a rather distinctive appearance for one of the so-called “Little Brown Birds,” the fox sparrow can easily be recognized by its behavior, too. This bird has a vigorous, distinctive way of foraging on the ground, kicking backward with both feet to uncover food. In fact, the instinct to forage in this manner means they are most often seen on the ground below a feeder instead of perched on a feeder like other birds.

Fox__Sparrow

Photo by U.S. Fish & Wildlife Service                                 A Fox Sparrow perches on a branch, giving a good view of the rusty-red plumage that inspired its common name.

I’ve noticed over the years that February and March is usually the best time of the year to observe this winter sparrow. Even when these large sparrows are present, it often takes a heavy snow to bring them out of their tangled thickets to our feeders. Other sparrows are less frequent visitors to yards, and can most often be found in the region during the migration season. These sparrows of the transitional periods between the seasons include savannah sparrow, vesper sparrow and swamp sparrow. March and April are good times to look for these sparrows.

Most fox sparrows spend the nesting season in remote, fairly inaccessible locations as far north as Alaska and Canada.  As a result, most people only see these birds during the winter months when they can become very reliable visitors to feeders. The recent heavy snows at the end of February brought a single fox sparrow to my feeders. The bird arrived early each morning and usually didn’t extend its visit beyond mid-afternoon.

They kick vigorously to uncover fallen seeds covered by snow or leaves.

Woodpeckers perfectly suited for their vertical lifestyle

IMG_5779

For most woodpeckers, a vertical lifestyle’s not a problem. These birds even have amazing adaptations to help them with their specialist lifestyles. For instance, their tail feathers are usually quite stiff to provide a means to prop the body against tree trunks as they excavate into the bark either in search of food or to fashion a roost or nesting site. Since they spend so much of their time hammering against tree trunks, woodpeckers even have special “shock absorbing” cushioning to protect their little bird brains.

Downy-2

Photo by Bryan Stevens                                                    A male Downy Woodpecker climbs along a branch.

The region is home to seven species of woodpeckers, ranging in size from the sparrow-sized downy woodpecker to the crow-sized pileated woodpecker.

English naturalist Mark Catesby, who died in 1749, gave the large pileated woodpecker the name of “large red-crested woodpecker.” Swedish botanist Carolus Linnaeus apparently gave this woodpecker its scientific name of Dryocopus pileatus. The Latin word, pileatus, translates into English as “capped,” and is derived from an old term that literally means “felt cap.” So, apparently, this woodpecker’s red crest reminded early observers of a red cloth cap. Another English naturalist, John Latham, apparently gave the bird the common name of pileated woodpecker, basing the name on the scientific name established by Linnaeus.

Pileated_woodpecker

Photo by U.S. Fish & Wildlife Service The Pileated Woodpecker is surprisingly evasive for such a large bird. Their presence in a woodland might go unnoticed if not for their noisy vocalizations.

The pileated woodpecker has actually had an abundance of common names associated with it, including wood-hen and “Good Lord Bird,” which was inspired by the common exclamation people make when they’re surprised by an unexpected observation of this rather large, often noisy, woodpecker.

Beyond this history of how the bird eventually got the name pileated woodpecker, there are a lot of folk names for this particular bird, including such interesting ones as “king of the woods” and “stump breaker.”

The loud vocalization of this woodpecker has also inspired names such as wood hen, Indian hen and laughing woodpecker. If anyone knows of other common names for the pileated woodpecker, I’d enjoy hearing about them.

Depending on whether you believe that the ivory-billed woodpecker still exists somewhere in Cuba or Arkansas, the pileated woodpecker is the largest of North America’s woodpeckers.

Pileated woodpeckers are cavity-nesting birds, and they use their large, stout bills to efficiently excavate their own nesting cavities in dead or dying trees. These cavities can be used in subsequent nesting seasons by such cavity-nesting birds as Eastern screech-owls and wood ducks, which are incapable of excavating their own nesting cavities.

IMG_5823

Photo by Bryan Stevens                                            A Red-bellied Woodpecker stops by a feeder during a snowstorm.

Male pileated woodpeckers show a red whisker stripe on the side of the face that is absent in the female. Otherwise, the sexes look similar. These large woodpeckers — they can reach a length of about 19 inches — often forage close to the ground on old stumps or fallen logs. The pileated woodpecker is widespread in the United States and Canada, favoring wooded areas in both countries. This woodpecker has proven adaptable, now thriving even in suburban areas offering sufficient woodland habitat.

During the recent bout of wintry weather with its abundant snowfall, a pair of red-bellied woodpecker have joined the downy woodpeckers as daily visitors. This is a bird that was once considered primarily a resident of the southeastern United States. It has expanded its range northward over the past century. It is often confused with its relative, the red-headed woodpecker. In truth, the red-bellied is named for a feature not readily apparent. Although it has red feathers on its belly, they are often hidden as the bird clings to the trunk of a tree.

The downy woodpecker, which occupies the other end of the size scale from its larger relative, is a rather frequent visitor to feeders. This small woodpecker, which is only about six to seven inches in length, frequents a variety of habitats, including open woodlands, parks and well-planted yards. The male shows a red crown patch at the back of the head, a feature which is absent in the female.

At feeders, downy woodpeckers like sunflower seeds, peanuts and suet cakes. Away from feeders, this small woodpecker is quite efficient at boring into trees in search of insects and their larvae.

Clinging-Woodpecker

The other woodpeckers in the region include red-bellied woodpecker, Northern flicker, hairy woodpecker, yellow-bellied sapsucker and red-headed woodpecker. Worldwide, there are about 200 species in the woodpecker family, which also consists of sapsuckers, piculets and wrynecks.

Some species have some very colorful names, such as the red-throated wryneck, arrowhead piculet, ochre-collared piculet, black-rumped flameback, crimson-winged woodpecker, imperial woodpecker, brown-capped pygmy woodpecker, splendid woodpecker, melancholy woodpecker and red-naped sapsucker.
