The rarest species of swallow to be found in the Pribilofs, the handful of records for this species suggest a late August arrival is the most likely time to locate this species in the islands, though the single late June record suggests that sightings are possible at other times too. […]

Bank Swallow
The most common swallow species to occur in the Pribilofs, this species is regularly found in the spring from the final days of May through June 20th, with very few occurrences prior to May 28th and a peak of occurrence from June 5th-15th. Sightings decline after June 20th during the summer though it can still […]
Cliff Swallow
A predominantly spring arrival in the Pribilofs, this species is less-than-annual at that time but still seen with some regularity. While records are scattered across much of the spring period from mid-May to mid-June, the majority of records have occurred from May 20th-June 1st and from June 15th-20th. The handful of summer records are generally […]
Barn Swallow
This species has been found regularly during the spring and summer, though it shows only a broad pattern of occurrence in the spring with the records spread evenly from late May to late June (but a slight peak in the June 5th-15th period). It is found less frequently during the summer with regular records only […]
Common House-Martin
The records from the Pribilofs account for more than half of the records in North America for this species. It is best sought during late spring (mid-June) or early fall (August) much like other species of swallows in the Pribilofs, which are found late in the spring and early in the fall. […]
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 […]
