Peregrine Falcon (Falco peregrinus)

Spirit was found on the Arcelor Mittal facility in July of 2013 and brought  to the Medina Raptor Center. She was a first year bird who was very thin and underweight. Examination determined that a granuloma tumor in her mouth prevented her from eating very well. The tumor was surgically removed, but the process caused her to lose a portion of her jawbone on the right side. She is an educational ambassador for the Center as a female counterpart to the males.



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.
