This presumed first-basic smithsonianus Herring Gull was photographed at Linkcrest
Landfill, Fort Worth, Texas, by Martin Reid in December 2002.
The undertail coverts are very sparsely-marked for smithsonianus,
but otherwise this bird looks fairly typical of those birds presumed
to be from the northwest (slender bill, long wings; short tail,
"gentle" head shape):
