Yellow-legged Gull Larus michahellis3cy, July 18th 2004, West Midlands |
© A. R. Dean
In active wing-moult. The innermost primaries are new and third-generation while the outer primaries are old and second-generation. P5 is missing. There are blackish markings remaining on the primary coverts, some of the lesser and median coverts and the tertials. The bare parts are quite adult-like and there is no sign of any black in the tail (in YLG this is quite common in third-generation feathers, unlike in Herring Gull). Compare this individual with another 3cy bird present during same period.
