Falco rusticolus

This species can be quite rare during the warmer months of May-October with only a couple spring records from May in recent years as this species moves north during March and April before observers are present in the Pribilofs. There is a single summer record from July, with a slight increase in records during the fall, mostly from mid-September on. It is most common in the islands during the winter with a large number of records from that period and considerable numbers present in some years despite the general lack of coverage during that season. It is most likely to be found locally during harder winters when sea ice is present.
