This 1st-Basic gull was photographed on November 26, 1991 at Brownsville
Dump, Texas by Martin Reid. This bird only came to light as it
was included in a shot of a 2nd-Basic LBBG (see lower photo) for
size comparison. There are a number of features that resemble
first-basic Western Gull (including a small skirt of visible secondaries),
and note the three dark-gray lower lateral scaps - what generation
are these? do they influence the ID? - any comments?:
