In mid-November I had the chance to spend several hours photographing and observing gulls roosting at the Chapora river estuary in Goa. I think the bulk of these were barabensis, with some cachinnans and perhaps the odd heuglini.  But given some of the lack of knowledge about separating these forms and the lack of photos showing juveniles and adults in moult of these birds, I am not sure of the identification of quite a few of the individuals.  I've put a selection of photos on this site: view adults here, and first calendar year birds here. I'd be very grateful for any feedback on them, to clivegharris@yahoo.com.
