| In colonial days, huge flocks of snowy
egrets inhabited coastal wetlands and marshes of the southeastern United States.
In the 1800s, when fashion dictated fancy hats adorned with feathers, egrets and
other birds were hunted for their plumage. By the late 1800s, egrets were almost
extinct. In 1886 the newly formed Audubon Society began a press campaign to
shame feather wearers and end the terrible folly. The campaign caught on, and
gradually, attitudes changed and new laws followed. Florida and Texas were the first states to pass laws protecting such birds. Then, in 1900, the United States Congress passed the Lacey Act, forbidding interstate commerce to deal in illegally killed wildlife, making it more difficult for hunters to sell their kill. Since then, numerous wildlife refuges have been established to protect the birds’ feeding habitats. A. (A) Predatory birds began eating the eggs of falcons and eagles. B.
