Mew Gull Larus canus canus; heinei; kamtschatschensis; brachyrhynchus

(last update: March 12, 2012)

Mew Gull canus adult, October 19 2016, Grou, the Netherlands.

Overall adult-like, including yellowish bill with bill-band. However, some of the coverts seem to show a brown hue, P10 has no white tip and a full sub-terminal band and also P8 and P9 have no white tips. Full band on P5 and some black on P4 is extensive in western birds (if this is a western bird). Maybe younger adult?
