hi,
is there any reference for on-the-route stops of steppe gull in migration and are there reliable timetables for leaving breeding grounds, stopover sightings and arriving at wintering grounds? when do the first steppe gulls arrive the gulf?

thanks a lot mars,
i trawled the materials on org but couldn't specifically find any arrival date in the gulf. is that a personal obs. of yours?
someone asked which gulls these are:

http://kookherdbirds.persiangig.com/ima ... rge-ID.jpg - they were photographed recently in southern iran (kookherd). i was pending between cachi and barabensis but the yellow legs that all 3 show at this timeand slightly later primary moult let me incline more towards barabensis. structurally they look more like cachinnans. possibly they are from kazakhstan
cheers and thanks,
lou
