Adult Western Caspian Gull (Larus cachinnans
ponticus), photographed by Martin Reid in Bahrain,
early March 1999. This bird is nearer the pale extreme for ponticus;
note the whitemirror/tip to P10, extensive pale inner-web tongue
in P9 and P8 (but these tongues are gray, not whitish as in the
palest ponticus), narrow black subterminal band on P5,
and lack of black on P4:
