Kumlien's Iceland Gull  Larus glauoides kumlieni@
Feb.3rd 2009 Choshi Chiba Japan

This 1st winter Kumlien's Iceland Gull was found on February 1st, at about 600m north from here . I (Michiaki) came across the same individual on February 3rd  with 4 Thayer's gulls in the same small flock! 

Update, Apr. 2013  Presumed the same individual in 2012 (4th winter) seemed better to regard as a intergrade/hybrid with Thayer's Gull.   Unfortunately nobody has found this individual in 2013 (5th winter).  







Note the thin, short legs compared with the Vega Gull.














After bathing, it showed a more "textbook" overall appearance of Iceland Gull which includes rounded head, small bill, short legs and long primaries.
