Not a bird that I take photographs of a lot, but they are real characters the Black-headed gull. With many roosts in Greater Manchester it's not difficult to know where they'll be hanging out. Quite often they're squabbling over some food that's been left to litter the pavement or just generally squabbling.
When there aren't many other birds around you can pretty much guarantee a Black-headed gull will help focus your attentions.
(No black or chocolate brown heads here as they are in winter non-breeding plumage)
I think this is a first winter bird, judging by it's plumage. Please correct me if I'm wrong. Gulls are not my greatest strength,
This chap looks more of an adult with it's nice reddish legs and no juvenile feathers in the wings.
