Herring Gull (argentatus & argenteus)

(last update: February 11, 2013)

Herring Gull adult, February 07 2013, Katwijk, the Netherlands.

Bird approaching characteristic set for smithsonianus regarding wing-tip. P10: Mirror separated from tip, P9 with small mirror on innerweb and black not reaching primary coverts, P8 grey tongue more than 3/4 of the innerweb, W-shaped black on P5. Also hint of bajonet on P6 but more so on P7. No clue on P10 tongue unfortunately, but of course this bird is way too dark.
