I was in Dubai last week. Please help me ID (preferably with an explanation) these two gulls and this raptor I photographed. I'm guessing that they are Caspian Gulls and a Black-eared Kite? I don't know.
Yes, those gulls are juvenile caspian gulls (quite rare for that location). You can see the pale pink legs, greyish area surrounding the eye, overall brown colouring, completely black tail, and slightly pink-ish bill with a black tip.
i see no reason why these first winter gulls wouldn't be steppe gulls (Larus fuscus barabensis). they aren't reliably separable from caspian gull but by far more likely and numerous in the gulf region. for instance, bill in the left hand bird is far from ideal for caspian gull. still, these are worn plumages which can virtually be identic in cachinnans and barabensis.
