A flock (~30) of Little Terns at the South Gare. Some have rings and one has a code which I couldn't quite identify.
I have had another look at the second photo and managed to identify the code as AW. I sent it to Chris Brown and he tells me that it is AW(NW32599) and was ringed at Crimdon on 8/7/14. The only other siting was again at Crimdon on 15/6/18.
