I didn't realise this black headed gull had lost his foot until I saw him on the computer. Poor little fellow but he didn't seem bothered by it all. I wonder whether he lost this in an accident or whether he was born like it. I've seen birds with only one leg before but not one with a leg without a foot
I have heard that they get their limbs caught in litter which gets twisted around and cuts off the blood supply - eg strips of plastic, elastic bands etc. poor gull.
