This Thayer's Gull (Larus thayeri)
was photographed at the Corpus Christi Landfill on January 06,
2005; is it too pale to be a pure thayeri and thus is it
an intergrade with kumlieni?:
This was a very small "large" gull, not much larger
than Ring-billed Gull:
Note the pale gray evident along the outer edge of the scaps,
both above and in flight below:
