Distinguishing features

It has a white head, belly, and tail with a dark slaty-gray back and wings with a broad white trailing edge.  The underside of the wings features a "string of pearls" pattern along their edges; these can be seen from below when the bird is in flight. Its eyes are yellow. The legs are pink and short when compared with those of similar-looking gulls, and the body appears more stout. The bill is yellow with orange-red subterminal spot. Immature gulls' plumage is brown. (Wikipedia).
