Resident Raptor - Peregrine Falcon
Leia, & Freyja
Leia Was found near the University of Oregon in November 2003, unable to fly. Her size indicates a female; her plumage showed she was a 'passage' of a first-year bird. Although radiographs showed no fractures and there were no surface wounds or apparent bruising, the x-rays did show a major tear in the flight muscles of the upper right breast. Such soft tissue damage can take a very long time to heal and may never heal sufficiently for the high speed stoops and long distance migrations for which peregrines are well known. After 8 months, it is obvious that the damage is too extensive for her to regain the flight capability she would need for release, so she joined our education program.
This delightful new addition to our diplomatic corps, Freyja, is a captive-bred, falconry-trained peregrine falcon, hatched in 2001. Freyja was given to us by her breeder and owner, the falconer who flew her for eight years but who is now retiring from the field. This bird spent her first four weeks with her avian parents, but then was raised in a playpen in the house and is very socialized and comfortable around people - certainly too comfortable for release. She was out wowing her new fans the second day we got her, when she traveled for an after-school program at River Road Parks and Recreation Center.
Peregrine Falcon (Falco peregrinus anatum)
A large, dark, powerful falcon with long, pointed wings and a long, narrow, tapered tail. Plumage is similar between the sexes, but females are larger. The Peregrine Falcon has a black hood that extends down along the side of the head in a distinctive wide mustache mark. Upper parts of the bird are a dark slate-gray and lightly barred; underparts are a whitish color at the throat, shading to a buffy color with elongated spots on the chest, and more dark barring across the abdomen; legs and feet of the adult are bright yellow. Like all other members of the falcon family, the Peregrine has a distinct notch in the upper mandible for cervical dislocation of its prey. This falcon flies with smooth, shallow, powerful wing beats, often soaring high with wings out flat and tail fanned when searching for prey, then diving and maneuvering at high speed to strike birds in midair. Peregrines are capable of gliding and flapping speeds up to 60 mph, and of reaching speeds up to 200 mph in spectacular dives called stoops.
Status - State and federally protected. Once on the edge of
extinction in North America from pesticide poisoning, Peregrines have made a
remarkable recovery through captive breeding programs and were officially
taken off the endangered species list in 1999.
