This species was not recorded in the Pribilofs until 2002 but has since been seen semi-annually with records during the spring, summer, and fall. Spring records all come in the month of June, with the 10th-20th being best, and summer records from late June and early July in line with the late spring sightings. In the fall it has been recorded from late August to early October, with most records involving long-staying individuals or multiple arriving individuals overlapping with each other during mid-September.
