"Adult female in breeding plumage.--Above, not so strongly mottled with black as the male, and consequently rather browner, especially on the head; black of face and under parts not so much developed, these parts being mottled with irregular black markings. Length, 279; culmen, 33; wing, 203; tail, 74; tarsus, 46. "Adult in winter plumage.--Differs from the summer plumage chiefly in wanting the black on face and breast, but, from the absence of black mottling on the back, the whole upper surface appears more uniform, being ashy brown with narrow whitish edgings to the feathers, before which is a blackish subterminal shade; lores white, but base of forehead like crown; a line of white above and below eye, but the white eyebrow scarcely visible above the ear-coverts, which are dingy blackish; sides of face white, streaked with dusky; throat and under parts pure white, lower throat and fore neck pale ashy brown, slightly mottled with dusky markings; under wing-coverts white, except the lower primary-coverts, which are dusky ashy; axillars black. "Young.--Like the winter plumage of the adults, and always to be distinguished from the golden plover by the black axillars, though it is spangled with golden buff on the upper surface, as is the latter species." (Sharpe.) The gray plover, known as the black-bellied plover in the United States, is found along the seashore in small numbers during the winter months. As seen in the Philippines it is usually in the gray plumage but as with its very near relative, the golden plover, individuals having the breast mottled with black are not uncommon. Genus CHARADRIUS Linnæus, 1758. This genus differs from Squatarola in being smaller and in lacking the hind-toe. 91. CHARADRIUS FULVUS Gmelin. PACIFIC GOLDEN PLOVER. Charadrius fulvus Gmelin, Syst.
