These birds were photographed on Lake Bekan, near Tselinograd in June 1987. The pale back colour, large white tongue on the inner web of P10, grey tongues protruding into the black on the primaries and the half string of pearls (white spots between the grey and the black) all point towards cachinnans. The very bright soft parts, dark undersides to the primaries and secondaries, modest-sized bill, and medium leg length all point towards barabensis. The white mirrors on P9 and P10 are consistent with both. These birds neither look like cachinnans that turn up in Europe, nor do they look like barabensis that turn up in the Gulf.
