Mighty Return of Peregrine Falcons

April 5, 2022

The Peregrine Falcon is known and admired around the world for its incredible speed, rarely surpassed by any other bird. These crow-sized falcons reach speeds of up to 180 mph in pursuit of prey. The worldwide peregrine population is more extensive than any other bird—they are found in North and South America, Eurasia, Africa, and Australia, preferring open country, high mountains, and tall buildings to construct their nests on ledges 50-200 feet off the ground. They mate for life and usually return to the same nesting territory each year. 

Not long ago, the peregrine falcon faced an uncertain future. Classified as “Endangered” by the NYS Department of Environmental Conservation (DEC), they were eliminated as a nesting species in the early 1960s due to the discovery of pesticide residues in their prey. The release of young peregrines bred in captivity in the 1970s and 80s led to their return in 1983, nesting on two bridges in New York City. The population grew steadily and by 2003 there were close to 50 pairs. New York City may now have the largest urban population of peregrines in the world. Nests can be found on every Hudson River bridge south of Albany, as well as several bridges further upstate and on cliffs in the Adirondacks.

Their resurgence has been so successful, the DEC has proposed reclassifying the peregrine from “Endangered” to “Special Concern,” still warranting attention but no longer threatened or endangered. Green Chimneys Wildlife Specialist Paul Kupchok, a member of the statewide falconry commission that has been advising the DEC on the reclassification, is one of many devotees awaiting the final decision to be made.


As the avian flu outbreak continues to spread, impacting domestic and wild bird populations across the country, Green Chimneys has made the decision to cancel Birds of Prey Day this June.
