Northern Harrier

Circus hudsonius

This species is predominantly a fall vagrant to the Pribilofs, with all records coming since 1997. It appears to be less-than-annual, though not an altogether unexpected vagrant, during the fall season with records in about half of the falls where coverage has extended into September and October.
