Known from two fall sightings in the Pribilofs (both from St. Paul Island), this species has also been found during spring in the Aleutians, though fall is likely the best time to come across this species in the Pribilofs from the end of August into October. […]

Northern Shrike
Primarily a rare fall vagrant to the Pribilofs, this species is a late arriver and is best sought during early October in the islands. The two winter records likely involve over-wintering birds that arrived during the fall. Pribilof records could involve birds from the New World or the Old World, though both of these subspecies […]
Warbling Vireo
A rare vagrant from the Alaska mainland, this species has only been recorded in mid-late September with a tight clustering of records around the 15-20th of September, likely indicating that to be the best time to look for this species. There are two subspecies groups of this species (Eastern and Western), which are occasionally split […]
Common Raven
Much like the Bald Eagle (Haliaeetus leucocephalus), this species has very different patterns on different islands within the Pribilofs. It is an uncommon resident on St. George Island (though as of yet, no evidence of nesting has been found) where at any given time one to several birds are typically present. Despite this, it is […]
Eurasian Skylark
This species has been found most commonly in the spring during mid-late May and in the fall in late September, though it is a sporadic migrant (vagrant) and may not appear in the islands for several years between sightings. There are records from two summer periods for this species as well but in both cases […]
Horned Lark
A rare fall vagrant, this species is best looked for during the month of September, though the extant records do not leave a strong sense of when is exactly best during the fall period. Records of this species include both the American-breeding (arcticola) and Asian-breeding (flava) subspecies, with the Asian birds being more likely than […]
Purple Martin
A rare vagrant to the state of Alaska, this species has been found surprisingly often considering, with records every 10-15 years on average in the Pribilofs. A late migrant in western North America, this species is most likely to be found in very late spring or early summer in the islands with late June or […]
Tree Swallow
A regular spring migrant/vagrant, this species is found most reliably from May 25th to June 1st, though it may be found as early as mid-May or as late as mid-June in the spring. There are only two known summer records: one from 1995 when remarkably a pair feeding young was found on August 1st, providing […]
Red-faced Cormorant
A year-round resident with reduced numbers during mid-winter, especially in heavy ice years, this species is nonetheless always present around the islands and can be found on nesting cliffs throughout the year. The fewer total birds present during the winter months is noticeable with the comparatively large numbers present during the spring, summer, and fall. […]
Pelagic Cormorant
A common spring and winter resident, which is found more rarely during summer and fall, this species can often be quite hard to see during some parts of the year. Small numbers are regularly encountered through the spring (until late June or early July), but numbers are often times quite small and this species can […]
