Black-tailed Gull

Larus crassirostris

Common along the coastlines of eastern Asia, this gull has wandered to western Alaska a few times. Isolated birds have been found at a wide variety of other sites from coast to coast in North America. Although these far-flung strays may have been assisted in their arrival, perhaps resting on ships for part of their journey, they also might have wandered there on their own.
