| | The Birds of North America Online: Peregrine Falcon (Site not responding. Last check: 2007-10-21) |
 | | The often-held image of the Peregrine as a symbol of wilderness diminishes when one sees this falcon breeding on metropolitan bridges and urban skyscrapers or watches tundra migrants on their neotropical nonbreeding grounds speeding along traffic-jammed boulevards at streetlight height in Rio de Janeiro, Brazil, or Buenos Aires, Argentina, chasing bats at sunset. |
 | | The Peregrine was, however, greatly harmed, along with other birds of prey and some marine birds, by the widespread use of persistent chemicals that lowered reproduction and survival rates. |
 | | By 1970, the Peregrine was federally protected in the United States, and the chemical culprits were virtually banned in North America by 1972. |
