Update: November 25 2006: I found some pics of this bird from six weeks earlier - click here.
This first-cycle gull was photographed in east Houston, Texas on March 15:
note the prominent gonydal angle, and obvious hook to the tip of the maxilla:
note the broad, rounded wings:
compare the mantle tone to that of the Laughing Gull at the left of the image:
note the two bands of paler feathers in the leading and trailing lesser underwing coverts:
note that the inner primaries
are paler on both inner and outer webs:
Note that the outer web of R6 is pure white from the base until the two subterminal black notches:
