photo 7287: Yellow-legged
Gull michahellis adult, October 14 2001, Westkapelle, the
Netherlands (51.33N,03.25E).
In the far wing, primary P9 and P10 can already
be seen. Michahellis is much faster in moulting the primaries than other
NW European large white-headed gulls. Note the upper two tertials lacking the
white tips.
