Gulls in Korgalzyn reserve, Akmola area, Kazakstan

All photos and recordings are taken in 1-3 July 2005. According to the literature, gulls in this area should be called either barabensis or cachinnans (or possibly both or something in between). They differ quite clearly from Black Sea cachinnans by having darker upperparts, more yellow feet and more black and less white on wing tip.

Two examples of cachinnans-like calls:
