Peregrine Falcon

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.


Meet our resident Peregrine Falcons:

Freyja is a delightful addition to our diplomatic corps. She was hatched in human care in 2001 and falconry-trained. Freyja was given to us by her breeder, the falconer who flew her for eight years but who retired from the field. She spent her first four weeks with her avian parents, but then was raised in a playpen in the house of her human parents and became very socialized and comfortable around people. She was out wowing her new fans the second day she joined our team, when she traveled for an after-school program at River Road Parks and Recreation Center. Freyja joined the Education Team in 2009. She is a patient bird who often helps staff “train” new bird handlers to the nuanced work of bird handling. Freyja is part of the outreach team.​

Leia, was found as a passage (first-year) falcon, unable to fly, near the University of Oregon in November 2003. Although radiographs showed no fractures, and there were no surface wounds or apparent bruising, x-rays showed 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 of rehabilitation, it was obvious that the damage was too extensive for her to regain the flight capability she would need for release. Leia joined the Education Team in 2004. Leia is part of the training as enrichment team.

Pip was found as a hatch-year falcon in July 2013 with a fracture of his left humerus. Although we do not know how he was injured, the fracture was fresh and should have healed together fairly easily. However, during surgery Pip did not tolerate anesthesia well, necessitating in two mouth-to-beak resuscitations. Medical staff did not want to risk him dying by completing the process of adding external fixators to the IM pin that would have been needed to completely prevent rotation of the bone ends at the fracture site. Unfortunately, without that final step, the wing did not heal in perfect alignment. Pip joined our Education Team in 2014, winning our staff “Rookie of the Year” award for 2014. Pip is part of the outreach team. ​

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.


Found in both forested and open country, up to about 10,000 feet. Usually live in an area with bluffs or cliffs overlooking rivers or lakes inland, or overlooking bays or ocean near an abundance of seabirds. Peregrines have learned the advantages of urban life in some regions, nesting on buildings and bridges, wherever pigeons are plentiful.


Almost all of their diet is small to medium-sized birds, usually captured in the air, but occasionally on the ground. The most common hunting technique is to hunt from a perch, taking off after passing birds; will also soar and circle, maneuver into position, and dive on prey to catch them in flight. Young Peregrines practice their midair hunting skills by going after flying insects.


Usually silent when alone, but vocal around other Peregrines. Will give a harsh rasping alarm call rehk...rehk...rehk... if an intruder comes near the nest.


This falcon usually scrapes out a shallow hollow for the eggs in an inaccessible spot -- on cliffs, high ledges, bluffs, or on ledges of buildings in cities. Will also reuse old nests of other species in trees. Peregrines may return to the same nest site over many generations. 

Most Common Problems

Peregrines are not seen often at rehabilitation facilities, but when they do come in, it is often with wing injuries from hitting power lines.

Range Map

World-wide distribution, mostly arctic to temperate zones. One or another of the several North American subgroups occurs in almost all parts of the continent at some time of the year. Arctic Peregrines migrate to South America to winter, where they continue to be at risk of pesticide poisoning.
