Black-tailed Gull

Larus crassirostris

The only records of this species from the Pribilofs, remarkably both of which occurred in 2008 on St. Paul Island, were in late spring and early fall. As with many species of gulls, this species could likely arrive at most any time though perhaps spring and fall are more likely than other periods.
