Peregrine Falcon

Falco peregrinus 

Peregrine Falcons are likely annual in the Pribilof Islands. Most sightings occur fall, from late August through early October. Because of the limited birder coverage of the islands during this period years can go between sightings. A few individuals have also been found during late May. Most sightings involve the very dark subspecies,Falco peregrina pealei, which breeds along the Alaskan south coast and the Aleutians. A few individuals of the Tundra breedingtundriusrace have also been detected. Often Peregrines remain on the island for weeks, no doubt feasting on the abundant seabirds, gulls, ducks and flocks of Lapland Longspurs and Snow Buntings. There have been unconfirmed rumors of actual nesting attempts by Peregrines on Saint George. A good technique if searching for this (or other raptor species) on the island is to watch the behavior of the islands resident birds. If an entire gull roost or cliff wall suddenly erupts in a frenzy definitely scan the skies for approaching raptors.
