A stunned rose-breasted grosbeak recuperating on the front porch on Oct. 3 provided a reminder that migrating birds face a variety of perils and obstacles as they wing their way back south. Now that we’re into October, many of the birds of summer — orioles, tanagers, warblers and hummingbirds — are becoming scarce in our yards and gardens. These neotropical migrants are temporary visitors, remaining in North America only long enough to nest and raise young before they take to the wing to return to more tropical regions for the winter months that will grip their summer home in snow and ice for several months.

Some of these birds migrate out of the tropics to avoid competition. Others find North America a land of abundant, albeit temporary, resources. This land of plenty offers a wealth of insects, seeds, fruit and other nourishing, nutritious food to help parent birds keep their strength while they work to ensure their young thrive. The phenomenon of migration isn’t exclusive to the neotropical migrants of the New World. Birds in other parts of the world migrate, too.

The Arctic tern, for example, truly takes migration to extremes. This small seabird travels each year from its Arctic nesting grounds to the Antarctic region, where it spends the winter months. Put into terms of mileage, the Arctic tern can travel about 50,000 miles in a single year. For a bird with a body length of about 15 inches and a wingspan of about 28 inches, this incredible migration is an astonishing feat.

The ruby-throated hummingbird, a favorite of many bird enthusiasts living in the eastern United States, makes an impressive migration each year. Just to reach the United States, these tiny birds undertake a strenuous 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! With the end of summer, the entire population of ruby-throated hummingbirds, increased by a new generation of young birds, makes the Gulf crossing for a second time in a year to return to the American tropics for the winter months.

The broad-winged hawk, a raptor found in the region during the summer, makes a fall migration back to South America every fall that astonishes human onlookers who gather along mountain peaks to witness the spectacle. The hawks form large flocks, also called kettles, that can number thousands of birds.

Shorebirds, which in North America can consist of birds ranging from plovers and godwits to dowitchers and avocets, are champion migrants. The bar-tailed godwit makes an even more impressive non-stop migratory flight. This shorebird nests in parts of Scandinavia, northern Asia and Alaska. Some of these godwits make a nine-day non-stop migratory flight that takes them from New Zealand to the Yellow Sea of China, a distance of almost 6,000 miles. Needless to say, since the godwits make no stops along the way, they must also go without food for the duration of their journey.

Most of the warblers that nest in North America retreat to Central and South America during the winter months. Few warblers, however, make as great a journey as the blackpoll warbler. Instead of migrating over land, this five-inch-long warbler undertakes a two-stage migration. The first half of the migration is a non-stop flight of about 1,500 miles. Every fall, these tiny birds fly over the ocean during this part of their migration, departing from Canada or the northern United States and not stopping until they reach various locations in the Caribbean. There they will spend some time recovering from the exhausting first half of their journey before they continue their way to such South American countries as Colombia and Venezuela. Once again, during the time they spend flying over open ocean, these tiny warblers do not feed.

Even birds that cannot fly undertake migrations. For instance, flightless penguins swim hundreds or thousands of miles to reach preferred ranges for feeding or nesting. The Australian emu, a smaller relative of the ostrich, makes seasonal migrations on foot to ensure access to abundant food supplies at all seasons.

Birds are not even the only animals to migrate. Many creatures, from whales and wildebeest to dragonflies and butterflies, impress humans with their endurance as they stage regular migrations.

Even as some of our summer favorites depart, we should prepare to welcome back some winter favorites, including dark-eyed juncos, yellow-rumped warblers, white-throated sparrows and yellow-bellied sapsuckers. Fall is indeed a time of departure for many birds, but it’s also a time to make new friends with the other birds that should soon start arriving in our yards and gardens.

As for the rose-breasted grosbeak on the porch, that story had a happy ending. After taking some time to recover after apparently striking a window, the bird hopped around the porch for a moment and then took wing and flew to nearby hawthorn trees. The bird’s flight — strong and straight — delighted me. The grosbeak could have been badly injured or even killed. I wished it the best for the remainder of its journey.

I’m dedicating this week’s column to the memory of J. Wallace Coffey, a great birder and wonderful individual who died Tuesday, Sept. 27. I met Wallace, a native of Bristol, Tennessee, back in the late 1990s. He introduced me to some wonderful birding destinations in the region, including such Virginia locations as Burke’s Garden, Steele Creek Park in Bristol, the wetlands of Saltville and Musick’s Campground on Holston Lake. Wallace was a tireless promoter of birds, birding and birders, and he loved to encourage young people to explore nature. He was also a great leader for the Bristol Bird Club, as well as the Elizabethton Bird Club. He will be greatly missed.

Hooded warbler favorite member from an exceptional family of birds

I watched a male hooded warbler flitting among the branches of a forsythia shrub during a soft rainfall on Sept. 18. As I watched the small bird dash after unseen insects among the thicket formed by the forsythia branches, I marveled at the bird’s exquisite appearance. The gold and green feathers seemed to glow brightly in the dim light as a drizzle of rain wet both bird and leaves. The black hood and bib surrounding the male’s yellow face stood out by virtue of its stark contrast from the brighter feathers.

The appearance of the male bird provides this species with its common name. The female has an identical yellow-green coloration as the male, although she is slightly more drab. She lacks the black hood and bib, although older females may acquire some dark plumage on the head and around the face. Both sexes also show white tail feathers that they constantly flick as the move about in thick vegetation and shrubbery.

I know that every migrant passing through my yard is making its way south and it may be another five to six months before I again see any of my favorite songbirds. The hooded warbler will make itself at home in the forests of Mexico, as well as Belize, Costa Rica and other Central American nations. Most hooded warblers begin returning to their winter haunts as early as mid-September, but lingering individuals continue to entertain birders in the United States throughout October.

Like many of the ruby-throated hummingbirds that make their home in the United States for the summer, the hooded warbler’s fall migration takes it across the vast open waters of the Gulf of Mexico, crossing to the Yucatan and then dispersing from there to various points in Central America. That birds as small as hummingbirds and warblers make this incredible migration twice yearly is one of nature’s most phenomenal feats of endurance.

The warblers, also known as wood-warblers, are an exclusively New World family of birds, numbering approximately 116 species. About 50 of these species of warblers make their home in the eastern United States and Canada for the spring and summer, departing in the fall and returning to tropical wintering grounds. Some of them are extremely bright and colorful birds. As I’ve indicated in recent columns, however, some members of the family show more subdued plumages of tan, beige and brown. The hooded warbler would have to be included among the more brightly colored warblers.

Other colorful warblers that share similar tastes in range and habitat with the hooded warbler include the American redstart, black-throated blue warbler and black-throated green warbler. None of the eastern warblers show any true red in their plumage, but red and pink warblers can be found south of the border. The pink-headed warbler, red warbler and red-faced warbler all make their home in Mexico and and Central America.

While some of the neotropical migrants that venture into North America boast even brighter kin in the tropics, we need not feel cheated with the warblers that make their home in the United States for half of the year. Some of their relatives are beautiful birds, including the white-faced whitestart, golden-bellied warbler, three-striped warbler and rose-breasted chat, but few can really hold a candle to their relatives that venture north and brighten the lives of the lucky humans fortunate enough to observe them during the summer nesting season or the seasonal migration journeys.

The hooded warbler has long been my favorite member of this family of interesting, energetic and engaging songbirds. Hooded warblers reside in the woodlands around my home, nesting and rearing young each year. I’ve never found a nest, but many years ago I watched a pair of hooded warblers fend off a song sparrow that ventured too close to one of their fledglings. Of course, the sparrow posed no realistic threat to the young warbler, but that didn’t make the conflict with the hooded warblers any less intense. The poor sparrow looked completely befuddled and uncertain about its offense. After the warblers drove the sparrow from the vicinity, I watched both parents deliver some food to the young bird.

Like most warblers, the hooded warbler feeds almost exclusively on small insects and arachnids. Some warblers will also feed on fruit, seeds and even nectar. The hooded warbler favors habitats featuring woodlands with an understory of smaller trees and shrubs, such as stands of willows or rhododendron thickets. Of course, a tangle of forsythia is enough to attract a visit from a migrating hooded warbler.

9781408134610The warblers have become such popular songbirds that they warrant field guides devoted exclusively to their ranks. My long-time favorite guide is Warblers of the Americas by Jon Curson, David Quinn and David Beadle published in 1994. More recently, other guides have been published, including A Field Guide to Warblers of North America, a book in the Peterson Field Guide series, and the Stokes Field Guide to Warblers. If you want a book to enlighten you about the magic of this family of birds, consider Chasing Warblers, a book by Bob and Vera Thornton about an adventure to find and photograph all 52 species of warblers that nest in the United States.

John James Audubon painted this image of Hooded Warblers about two centuries ago.

The warblers are, in short, an incredible family of birds. I’ve seen all but a handful of the species that reside for part of the year in the eastern United States. I still want to see a Connecticut warbler and cerulean warbler, as well as the endangered Kirtland’s warbler of Michigan and the golden-cheeked warbler of Texas. I’ll miss the warblers once fall migration has run its course. For those few months they are here, the warblers belong to us. They seem like “our” birds. They’re only on loan, though. Our winter birds bring their own favorites back to our yards, but I’ll be impatiently awaiting that flash of gold in the shadows of a rhododendron thicket next April.
