? Жаўтаногая чайка (Larus michahellis)

1 птушка.

Фоты і вызначэнне з Western Palearctic Gulls:

you have all 3 taxons in one pic: argentatus (with the striated head), cachinnans with yelllow legs (the larger one with small dark and oval eyes) and a michahellis, the one with the shortish yellow legs. separating the latter from an 'omissus' type herring gull is not easy but it has a very bold p5 subterminal mark (visible in first pic), a smallish p10 mirror (last pic) and no long ventral p10 tongue - most of the underside of p10 is black, which strongly favours yellow-legged gull.
