A large bird was being mobbed by gulls over larkhill this morning. Had a jizz similar to a cuckoo; very long tail (at least the length of the rest of the body) reletively short sharp wings and a very protruding head. The bird however was of simular size to the herring gulls mobbing it. It appeared dark, and the call resembled that of a grey heron, flight was not unlike a bird of prey. I assume that it must have been an escaped bird like a macaw or something as I've never seen or known of anything like it in this country.
