A newspaper columnist where I live, in an attempt at humor, once complained in print that birds are noisy, flying nuisances that wake him at dawn and dirty his car. He saw no good reason for birds and suggested they be eliminated. He ridiculed birders like me as oddballs who parade around the woods in paramilitary get-ups. A golfer, he proclaimed that birding has about as much sport as watching the grass grow.

As advancing fall sends a new generation of songsters south with their parents, I offer this defense of birds and birders.

Birds are important for a simple reason: they are here. Yes, they control insects, but their benefit to humanity is no more the measure of their worth than the pharmacy shelf is the measure of the tropical rain forest. Wildlife has a right to exist for its own sake. The height of species-ism—a distinctly human prejudice—would be to suggest that nature's profound creations must justify their presence to us. As if it were our place to grant birds permission to live!

Birders are not frail, bookish fanatics in pith helmets and safari jackets. We dress like other people who frequent the woods, adding binoculars and perhaps a field guide. We don't do back flips at the sight of a yellow-bellied sapsucker, a bird that, east of the Rockies and across much of Canada, is not particularly unusual. When I go birding, I usually hike for miles, and I bird several times a week year-round, regardless of the weather. Watching birds, I have learned about them and about me, and I have gained admittance to the secret society of the wild.

Like the best sports, birding challenges the physique, the senses, and the intellect. To see birds in all their wondrous forms, you would have to visit the wetland, the coast, the open ocean, the mountaintop, the desert, the prairie, the jungle, the river rapids, the tundra, and the polar regions. When millions of birds migrate across North America—returning to northern breeding areas in spring and departing in fall for winter homes as far away as South America—birders around the country go afield to witness the mysterious and inspiring spectacle.

Why do people go out of their way to find birds? Birds are beautiful to look at, they make an incredible variety of sounds, and they exhibit fascinating behavior. A rare bird is as thrilling as the most precious gem. Birds come in all colors, and in this country they range in size from the 3.25-inch calliope hummingbird to the California condor with its wingspan of nearly 10 feet. Whether a bird's song is short and sweet or long and musical, virtually all bird songs are memorable and stirring.

Birds, in short, show nature's diversity in all its glory, and watching birds is nothing less than a celebration of life. But I think the real fascination with birds is that, more than any other creatures, they embody the freedom and wildness about which we humans can only dream."Free as a bird" undoubtedly stands in the Pantheon of Clichis, but for good reason.

Birds are a living fantasy.
I watch them fly in disbelief.

These colorful, almost mythical feathered sprites defy gravity at will. They go wherever they want, whenever they choose, some at lightning speed. They are more beautiful and exotic than any extraterrestrial being Hollywood could concoct, and yet they are here, at our doorsteps, for us to enjoy. Birds are a living fantasy. I watch them fly in disbelief. They decorate the trees with their nests.

Living in humanity's overpopulated, paved-over world—with all its rules, regulations, and traffic jams—I think we envy the birds' wild freedom. We want that freedom and wildness for ourselves. And so we birders watch, listen to, identify, count, list, house, feed, and photograph birds.

Admittedly, it's a vicarious experience, but it satisfies a deep natural urge within us. This is the same urge that drives people who hunt. Yet birders can possess nature's freedom and wildness without snapping the chain that joins us to all living things.

People who have cut themselves off from nature are, at best, indifferent to birds; at worst, they view birds, birders, and wildlife as bothersome and unnecessary. They don't really care if so-called developers gobble up wildlife habitat, if pollution poisons the water and air, if birds decline and disappear.

Roger Tory Peterson, the famed author of bird guides, once remarked after a visit to China that vast areas of the world's most populous country were almost devoid of birds, which have been crowded out by unchecked human development. Tirades against wildlife disturb those of us who feel close to nature because we fear the rest of the world's birds may suffer the same fate. The southward migration of birds is ushering in another fall, but each year it seems that there are fewer travelers.
