Peregrine Falcon

Falco peregrinus

A surprisingly rare visitor to the Pribilofs, this species is very rarely encountered during the spring (mainly mid-late May) and has been seen only a few times during the summer in late June, mid-July, and early August. It is found more commonly during the fall with occasional records from mid-August to mid-September, after which the species becomes more regular. The peak of fall migration appears to be from September 20th-October 5th though the species may remain throughout the fall and into the winter. Winter records are sparse though this species is likely regular at that time much like the Gyrfalcon (Falco rusticolus).
