This species has been recorded on a regular, though semi-annual basis in the Pribilofs. Many of these records involve irruptions of birds over a span of time or individuals that spent an extended period of time on the island. There is only one arrival record from spring (late May), with six summer arrivals (mostly mid-late […]
This irruptive species has been recorded on an irregular basis in the Pribilofs. Many of these records involve irruptions of birds over a span of time or individuals that spent an extended period of time on the island. There is only one arrival record from spring, as this species is more likely during the summer, […]
This irruptive species has occurred as a semi-annual vagrant in the Pribilofs. Only a couple records are from the spring in late May and mid-June, while the majority of records are from the summer and fall. There are a number of summer arrivals with most being found during the month of July. Fall is the […]
Only recorded on three islands in North America (two records on St. Paul, two on Attu, and one on St. Lawrence), this species is an extremely rare vagrant to western Alaska with four records from the spring and one in the fall. Most of the spring records come from the beginning of June (the one […]
This species has been recorded in the Pribilofs as a regular vagrant with several records involving multiple individuals present over an extended period of time. Spring is best and the majority of spring records are from June 5th-15th though it has been seen starting in late May with a couple early summer records from late […]
A very rare spring vagrant, this species is most often found during fall when it is less-than-annual but not unexpected. During the spring this species is most likely to be found in late May, while the best period to look in the fall is from August 20th-September 5th. Records into late September are similar to […]
A rare fall vagrant, this species is most readily found in late fall during late September and early October and has been annual on the Pribilofs in recent years. Fall records have occurred as early as mid-September, while the two spring records from early-mid June are in line with the timing of records of other […]
A rare vagrant species that has been found in three distinct time periods during the spring and fall. The spring records are centered on June 1st, while fall records have been found during two time frames, the end of August, which is similar to several other Old World Flycatchers, while the other records come from […]
The first, and so far only, record for North America of this species was found during early October on St. Paul Island. This long-distance migrant breeds as close as central Asia and while further records in North America are unlikely, the late fall period is the most likely time considering range and timing of migration […]
This species is a regular spring migrant that has been found from mid-May to mid-June with the peak of occurrence during the final week of May. It is relatively rare during June in the spring and no records have come from the early summer period. The only summer records are from late July and early […]
