Hi Dave, it appears to me that the IOC distributions are given for the breeding grounds only and do not include the wintering distribution. If, for instance you look at Latham's Snipe, they are not listed as occurring in Australia, only Japan and nearby where they breed. The major wintering grounds for the heuglini race of Lesser Black-backed Gull extends from the eastern Mediterranean east to Japan. Robson in his Birds of SE Asia includes them as a full species with a status of rare to locally fairly common in parts of Thailand. This taxon has occurred just to our north on Wetar so is to be expected one day in Australia.
Did you really go to Thailand without a copy of Robson?
