Adult Herring Gull, performing the 'Mew call': a long-drawn, plaintive call given with the bill wide open. During this call it displays a distinctive posture with the head held down, the neck in a characteristic s-bend, and the wings raised from its supporting flank feathers. All this is aimed at intimidating a rival.
