THE PASSENGER PIGEON
We Americans have been a greedy heedless people plundering and wasting the natural resources which made possible the building of this great nation -- the soils, the waters, the forests, the minerals and the wildlife, In the United States there was once an abundance of wildlife never found on any other land. We have come close to exterminating many valuable kinds, notably the buffalo and the beaver. Several species once abundant are extinct, among them the Passenger Pigeon.

The passenger pigeon was a graceful elegant bird with a long wedge- shaped tail, considerably larger than our Mourning Dove and mighty good to eat. The males were handsome: slaty blue and brown above; the head blue; the sides and back of the neck iridescent with pink, purple, green and gold; the breast a rich reddish-brown shading to pinkish on the sides; with short stout red legs. Unlike other doves and pigeons, its voice was rather loud and harsh. The females were more drab in color. Native to the unbroken forests which covered most of central and eastern North America, they nested in huge colonies. An area of 100 square miles might have every tree loaded with nests, some times 100 nests in a single tree. The nests were merely a crisscross jumble of sticks in which one pure-white egg was laid.

Those billions of wild pigeons fed on mast -- the acorns, beechnuts, chestnuts and other seeds on the trees and on the ground; also upon the many kinds of berries so plentiful in those days, as well as upon caterpillars and other insects -- a much wider variety of food than any of our present-day pigeons and doves. Feeding on the ground, a flock would extend over a wide front, moving rapidly forward, with one rear rank, and then another continually rising in the air and dropping down ahead so that, as the flock surged along with a rolling motion, the ground was swept bare of pigeon food.

Their migrations were not the regular seasonal flights of most birds but mass migrations in search of food. Audubon, the great naturalist, observed a flight over Louisville, Kentucky, in 1813, which darkened the sky as if by an eclipse of the sun and continued to pass over "in undiminished numbers" for three successive days. In 1832, another great ornithologist, Alexander Wilson, estimated that a single flock which roosted in Kentucky and fed in the beech forests of Indiana, contained at least 2,230,270,000 birds and possibly twice that many. Audubon measured one pigeon roost more than 40 miles long that averaged over 3 miles in width, where large branches and even big trees were broken down by the weight of the birds.

There were other gigantic flocks that nested in Arkansas, Missouri, Michigan, New York and other places. Wherever they were, wherever they went, the market hunters followed and slaughtered them. They were decoyed, trapped, netted, shot, clubbed, caught at night, and suffocated with sulfur fumes. The young -- the tender squabs -- were taken by millions and shipped to market or dried, smoked, or pickled for winter use. In the northern birch forests, the trees were set afire, causing the young birds to leap from the nests, to provide food for fattening droves of hogs.

The last great nesting in Michigan was at Petoskey in 1878. At least 300 tons of birds were shipped to markets, and possibly a hundred million or more birds killed by the 5000 netters, hunters and laborers who made their living there that year. That was the beginning of the end. By 1890, only a few stray flocks remained, here and there in the Middle West and Southwest. In 1908, $1000 was offered for a pair of passenger pigeons because the only known survivors were about a dozen in the Cincinnati Zoo. On September 2, 1914, the last one died.

They are extinct -- gone where the dodo did.
