Larus cachinnans adult UKK T-00150x January 03 2008, central Austria. Picture: Wolfgang Schweighofer.

An adult bird with partially read Ukraine ring: metal ring Kiev (UKK) T-00150x; probably ringed at Kanev, Cherkassy O., Ukraine (49°46'00"N, 31°28'00"E).

Pale iris and completely lacking any black on P5. Greg Neubauer photographed a breeding adult Caspian Gull at Azov Sea, Ukraine, in May 2001. This bird also had only five black-tipped primaries. While this is very rare in Caspian (just a single bird amongst the 100 adults examined in the hand), such birds do occur in the core range of Caspian, as illustrated by these individuals.
