The Comeback of the Peregrine Falcon

From Yellowstone Natinal Park:

Peregrine falcons were listed as an endangered species in 1970 due to rapid loss across huge swaths of North America, including Yellowstone, due to the widespread use of the pesticide DDT. Representing a major success story of the Endangered Species Act, peregrine falcons have made a spectacular comeback and were removed from listing in 1999. Assisted by a country-wide ban of DDT in 1972 as well as an aggressive captive breeding program, Yellowstone is now a peregrine stronghold with at least 29 active eyries, or cliff nesting sites. Once again these stunningly beautiful -- and fastest of all birds -- are a common sight along Yellowstone’s cliffs and rivers.
