Observation details
Juvenile. Possible confusion with juv. Laughing Gull, but photos show the following: (1) black tail band fairly narrow and does not include outer tail feathers, which make a margin of white on sides of tail (vs. broader and covering entire tail in Laughing); (2) black wingtips fairly limited both above and (esp.) below, where black is a triangle and rest is white (vs. much more black in primaries in L., which we thought we saw in the field but photos contradict); (3) size considerably smaller than Ring-bill, more so than typical L.; (4) bill black, paling slightly at base, slenderer than Ring-bill's and straight (vs. longer and drooping in L.); (5) some nuances of plumage.
