Only a few records of this mobile and irruptive species have been recorded in the Pribilofs (all from St. Paul Island). Most records are from the spring during late May and early June, with a further fall record from early-mid October. This species often migrates in early spring and late fall and subsequently may be […]
A rare-but-regular fall vagrant that has been found on a semi-annual basis when fall coverage extends through September and into October. The records are evenly distributed from mid-September to mid-October, though the end of September or beginning of October is likely the best period for sightings of this species in the Pribilofs. […]
An annual, though not common spring migrant in the Pribilofs, this species may be seen as early as mid-May or as late as mid-June, with a peak from the last few days of May through June 10th. There are few summer records with several late spring records in late June and early July and no […]
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. […]
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 […]
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 […]
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 […]
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. […]
A rare, but regular, vagrant to the Pribilofs, this species has been found almost annually when coverage has extended into the late fall period. The second half of September appears to be the most reliable time for this species to occur though they have been found across much of the fall period from late August […]
This is one of only three species of passerine that is a permanent resident in the Pribilofs. While always present in the islands, the populations on various islands are quite different with regular major population shifts due to winter weather. On St. George Island, this species is an uncommon to abundant resident depending on the […]
