This first-cycle gull was photographed on January 011, 2007 in the Coastal Plain near Houston and Galveston, Texas; it is a LBBG/YLGU-type or some kind of hybrid. Note the following features:- stout bill all-dark; longish, thick legs; full chest but without the long rangy rear-end of LBBG (tail is midway between tertial tip and wing tip); extensive wear on the pale parts of the first-generation upperparts feathers; palish head with slight mask above/behind eye; pale band on the median underwing coverts; the leading lesser upperwing coverts do not contrast strongly (darker) with the rest of the lesser/median coverts, as they do on LBBG; outermost tail feathers unmarked white except for subterminal black patch and small notch near tip of outer web; dark marks on the distal uppertail coverts are diamond/triangular-shaped; dark marks on undertail coverts are spots, not bars:
