A regular migrant in small numbers, this species is most reliable in spring during late May with only five June arrivals recorded. In fall they are seen most often after September 25th. The only three summer records are late July arrivals with no further records until late August in the fall, but there are only several records from the month of August and similarly few from early September. Individuals are regularly recorded into October and should be encountered in the islands as long as open water persists into the late fall and winter. There are only scattered records from November to April due to coverage but this species is a likely a regular winter visitor when the Bering Sea stays open around the Pribilofs.
