2nd winter
Thayer's Gulls Larus
March 26th 2013 Choshi Chiba Japan

Interestingly, most Thayer's Gulls found in Choshi 2012-2013 winter were 2nd winter birds. We assume many of them are the same birds as 1st winter birds that were found abundantly in the previous winter

A white-headed, pale-eyed atypical one.

A very dark individual.
