Scan the squawking rabble of mainly Black-Headed Gulls that can been seen and heard during the day (especially afternoon) at the RSPB Snettisham Reserve and you may see the odd Mediterranean Gull. These are distinguished from our comparatively bland chocolate-faced, so-called Black-Headed gulls by their full jet-black hood (like an executioner's mask), their red beak, their seemingly whiter eyes, their absence of black wing-tip feathers and their larger stance. They also make a far more refined "air-ooow" cry and are a bit more stroppy, but then they'd need to be! This clip shows a couple of handsome Med Gulls (a third runs past) that can be compared against their black-headed relations.
