Atlas

Atlas-Peregrine Falcon

 

Peregrine Falcon (Falco peregrinus)

Atlas was brought to the Medina Raptor Center in October 2010 as a first year bird after he was rescued from a field in Muskingham County. When he was found, he was very thin and had a left shoulder injury. How he received the injury is unknown, but due to the nature of his injury, he was no longer able to achieve any height in flight and became a most wonderful educational ambassador for the Center and for his species.

 

 

 


About Peregrine Falcons

(Information taken from the Cornell Lab of Ornithology)

Powerful and fast-flying, the Peregrine Falcon hunts medium-sized birds, dropping down on them from high above in a spectacular stoop. Virtually exterminated from eastern North America by pesticide poisoning in the middle 20th century, restoration efforts have made it a regular, if still uncommon sight in many large cities.

Conservation Status

Populations crashed in 1950-1970 because of DDT poisoning; eastern population extirpated. It was declared an Endangered Species, and extensive efforts were made to reestablish birds in East, beginning with the work of Tom Cade in 1970 at the Cornell Lab of Ornithology, which eventually developed into the Peregrine Fund. The species recovered enough to be removed from the Endangered Species List in 1999.

Sound

Alarm call a loud series of harsh “kak, kak, kak.”
