This gull was at Elliot Landfill, Corpus Christi, Texas on March
18, 2005; it has the structure of a Western Gull with the plumage
of a LBBG (mostly). I feel this gull has some Kelp Gull
in it - but how much? Perhaps it is a first-summer Kelp, though
the timing seems wrong for a Southern Hemisphere breeding cycle...
but maybe there are some Kelps somewhere (Caribbean? West Africa?)
breeding on a northern Hemisphere cycle: Below is a darkish Lesser Black-backed Gull
at the same location/date, for comparison:
