It’s not just our Lesser Black-backed Gulls that are wearing colour rings at Castle Semple. There are also Herring Gulls and more recently we have caught a Common Gull and fitted it with a yellow and black ring, 2J09. All these birds are spotted at Castle Semple on a frequent basis but when they aren’t here and not wearing tags we rely on the public to let us know where they are. So if you spot a gull with a ring on, write down the number and let us know. If you spot any other birds, swans, geese etc please report them to the British Trust for Ornithology
