Gulls -- with some oddities

(c) Harry J Lehto

Photographed in Ijmuiden, Netherlands, Sept 28 1998.

Figure 1. The bird above bird is a normal 1st winter Herring gull Larus argentatus (likely to be of the race argenteus) except for the unusual tail pattern, which shows a pale subterminal bar. A similar pattern is apparent also along the wings and is best reflected in the primaries.
