"Young.--Forehead white, rest of head chiefly grayish brown; upper surface warmer brown, with gray lower wing-coverts; secondaries with blackish centers and white borders; the three outer primaries black on outer webs and at the tips and margins of inner webs, but the centers white, except the outermost, in which there is for a time a dark line inside the shaft; in the succeeding primaries the dark color increases ascendingly on the inner webs, while from the fifth the outer webs are pale gray to brownish, with a little white at tips; tail-feathers white, with a band of blackish brown; under surface dull white. Bill dull yellow, passing into black at the angles; tarsi and toes dull reddish yellow. The brown color is soon lost on the back, which has become gray by December. "Immature.--Like the adult, with a few brown markings left on the upper wing-coverts, and more black on the outer webs of the primaries. More or less of a brown hood is assumed when the bird is barely a year old, and the band on the tail is lost by the following autumn, when the new primaries appear, with, as has been said, a larger proportion of black than in the adult; in fact the duration of the immature phase is very short. The bird does not breed until the following, or second spring. "Occasionally the black from the margins of the inner webs of the three outer quills runs in and reaches the shafts, much encroaching upon the usual white centers, though not to the same extent on both wings of the same bird. This is noticeable in two examples obtained at Dinapur in December." (Saunders.) This small gull is often abundant about Manila Bay but does not remain throughout the year. 87. LARUS VEGÆ (Palmen).
