From the Publisher
Through barren winters and abundant summers, from the Chilkat’s council of eagles in Southeast Alaska to Prudhoe Bay’s dump-dwelling ravens in the Arctic, birds earn a special place in our imaginations with their enchanting songs, fascinating antics, rich plumage, and mastery of the compelling phenomenon of flight.
Exploring Alaska’s Birds presents a colorful survey of the realm of birds in the forty-ninth state. An examination of avian evolution reveals their roots in toothy dinosaur ancestors. A scientist’s study of migration pathways probes the mysteries of the miraculous navigation system that guides them across continents and oceans.
Exploring Alaska’s Birds explains how species get their names, provides insight into bird talk, describes their adaptations to ferocious Alaska winters and considers the range of Alaska bird research from backyard feeder observers to the unique facilities of Middleton Island.
Avid birders pursuing the 200th species on their life list or backyard naturalists merely curious about the feathered denizens of the Great Land, and all those who’ve ever asked, "What bird is that?" will appreciate Exploring Alaska’s Birds’ authoritative presentation of useful information illustrated with a wealth of world-class photography.

Chapter 1. Birds and People. Citizen Scientists.
Birds inhabit a special place in the human heart and imagination. Whether we are young or old, and whatever our culture, birds enchant us with flashes of color, snatches of song, and their miraculous powers of flight.
Humans have never known a sky empty of birds. Our feathered friends evolved during the Jurassic Period, at the height of the age of dinosaurs, and predated us by 150 million years.
Today, we share our planet with nearly 10,000 species of birds, from enormous, flightless ostriches, nine feet tall and weighing 350 pounds, to delicate hummingbirds, small enough to alight on the palm of a child’s hand. Birds are warm-blooded, lively, often colorful, and striking to behold. Many sound elaborate calls and intricate songs, which resonate in the human heart.
Birds tantalize us, too, with their sudden appearance and disappearance. As I write, a black-capped chickadee swoops into view and alights on a branch outside my window. It shoots glances about with sharp eyes, then seemingly satisfied, chirrups a few bars of a call. An instant later, the chickadee darts off in a burst of flight I can only follow with my eyes. Where did it come from? Where is it going? What does it feel, how does it experience the world that we share?
In such encounters, for moments all too brief amid our busy days, the most common bird has the power to pull us outside of ourselves. Birds bring us scraps of nature, snippets too fleeting but nonetheless vital and nourishing to our souls. A world without birds would be a profoundly impoverished place.
Ornithology, the study of birds, is unusual among modern scientific disciplines in that amateur bird-watchers can still make meaningful contributions to the field. With billions of birds spread across the planet, scientists sometimes rely on observations by amateurs to uncover and document important facts and patterns in the field.
One scientific program that solicits amateur help is Project FeederWatch, a joint effort of the National Audubon Society, the Cornell Laboratory of Ornithology, and a pair of Canadian groups.
Audubon officials and scientists at the Cornell Laboratory refer to their amateur collaborators as Citizen Scientists. In fact, some collaborators are trained scientists who participate on their own time, out of personal interest. But whether amateur or professional, Citizen Scientists often find their studies rewarding.
An even larger citizens’ effort is the annual Audubon Christmas Bird Count, or CBC. Each year around Christmas, birders fan out across North America to observe and record every individual bird and bird species found within a designated area during a 24-hour period.
The first Christmas Bird Count took place on Christmas Day, 1900, and counts have been held every year since then. The CBC has grown to be the largest and longest-running wildlife survey in history. More than 45,000 volunteers now participate each year, in some 1,700 counts in 50 states and every Canadian province. Recently, counts have been added in the Caribbean and at Central and South American sites where North American breeding birds winter.
The 1900 Christmas Bird Count was organized by ornithologist Frank Chapman in response to a holiday custom of the period called the "side hunt." Teams of hunters set out to shoot as many birds and small animals as they could in a single day, with the "victory" going to the side that bagged the most. To protest the side hunt, Chapman organized 27 friends in 25 locations to venture afield and count birds, rather than to shoot them. The practice has been refined over the years and has been relatively standardized since the 1940s. Each count now canvasses a well-defined circle 15 miles in diameter. Most counts are conducted by collegial groups.
The first Audubon Christmas Bird Count in Alaska took place in Anchorage, in 1941. The second took place in 1959, also in Anchorage, and Alaska counts have been held every year since . . .
Birding on the Edges
For anyone interested in the wide range of North American birds, Alaska is one of the continent’s most exciting places. That includes Thede Tobish, a past president of the Anchorage Audubon chapter and one of the state’s top birders.
"For hardcore birders who are interested in their North American list, there are obligatory places you go," Tobish explains. "Southeast Arizona, south Texas, south Florida, and Alaska—those are the big ones."
It is no coincidence that the spots on Tobish’s must-see list are all on the margins of the United States. Floridians might well see birds common around the Caribbean and in Central and South America, while Mexican birds often drift north into Texas and Arizona. Alaska, in northwestern North America, is home to boreal or far-northern species seldom seen elsewhere in the United States, along with birds ordinarily found in Asia.
Tobish began watching birds with his father, in eastern Pennsylvania. "He was mainly interested in spring warblers and he just passed it on," he says.
In 1973, Tobish moved to Alaska to attend college. Soon, his interest in birds grew to the verge of obsession. "In the 1970s, Alaska was very much a pioneering place for studies of bird status and distribution," Tobish recalls. "It still is. The size, the remoteness and difficulty of access, historic knowledge [of birds] was very limited. So it got very exciting, very quickly. Even today, anywhere you go in Alaska, you have a chance to uncover something new and distinct."
Compared with our feathered friends of the class Aves, we Homo sapiens are newcomers on this Earth. Whether birds evolved during the Jurassic Period, as paleontologists believe, or whether God created creatures of the air on the fifth day, as Genesis would have it, birds soared, sang, migrated, nested, and inhabited the surface of the Earth, nearly from pole to pole, long before human eyes or ears beheld their beauty and grace. . .
