Hi all,
Just wanted to let you know I have belatedly put up some identification notes and photos on Bird-O on the differences between Gull-billed Tern subspecies macrotarsa and affinis, courtesy of Martin Cachard. Thanks Martin for putting the differences into words, it might seem easy once you know what to look for but I know from experience in Broome it takes a little while to get your eye in on them.
