Worldwide species of falcon whose decline in the 1950's brought to the forefront environmental problems of chemicals such as DDT. The Peregrine population in eastern North America had disappeared and the species was in decline in Europe and Northern Asia. Recovery efforts as well as banning use of organo-chlorines have aided in the comeback of Peregrines. © Mary Hennen.
