This gull was at the Elliot Landfill, Corpus Christi, Texas on
December 28 2004; whenever I see such a pale bird, I expect it
to be a 2nd- Basic - but close examination of this bird shows
it to be 1st Basic, and as such a good fit for Vega
Gull Larus {argentatus} vegae:
Below, there is a 2nd-basic Herring Gull behind the bird, for
comparison:
Note on the 2B HERG the blacker, rounded 2nd- generation primaries,
the marbling on the lower teritals and on the inner greater secondary
coverts, and the much fresher condition of the wing coverts and
tertials:
