An annual fall migrant/vagrant in the Pribilofs, this species was not recorded prior to 1996 but has been seen during each fall with coverage past mid-September since that year. It is best found during the final week of September, though it has been found with some regularity between mid- September and mid-October. The single summer record from early August and the mid-October records of this species may indicate that they can be found from the very beginning of southbound migration and remain later into fall than records indicate in years with mild weather. This species is often found for extended periods when they arrive, with several of these fall records involving the overlapping arrival and departure of multiple individuals.
