Passenger pigeons (旅鸽)once flew over much of the United States in unbelievable numbers.
Written accounts from the 18th and 19th centuries described flocks (群)so large that they the sky for
hours.
It was calculated that when it population reached its highest point ,they were more than 3billlion
passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly the abundance of passenger pigeons may have been their undoing. Where the birds were
most abundant, people believed there was an ever-lasting supply and killed them by the thousands,
Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century ,the hardwood forests where passenger pigeons nested had
been damaged by American’s need for wood, which scattered (驱散) the flocks and forced the birds to
go farther north, where cold temperatures and storms contributed to their decline. Soon the great flocks
were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons but by then,
no sizable flocks had been seen in the state for 10 years. The last confirmed wi pigeon in the United
States was shot by a boy in Pike County, Ohio, in 1900. For a time , a few birds survived under human
care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on
September 1, 1914.
