Adult male.—All of head, neck all around, back and interscapulars light gray; chin white; lower throat delicate light gray, bordered behind by a narrow white band and this followed by a wide, dark gray band on fore breast; lower breast, abdomen, and flanks dark chestnut, darker and slightly purplish on breast; sides gray; alula, primaries, and their coverts, dark, glossy blue-green; secondaries blue-green, mealy along outer edges; wing-coverts and inner secondaries canescent, the smaller feathers each with a dark spot at tip; rump-feathers canescent with glossy green centers and light purple edges; rectrices and upper coverts glossy blue-green, shafts black; rectrices black below, except outermost pair which are brown with white shafts. Iris white mottled with pink; bill rose-pink, the “nail” white; legs rose-pink, nails brown. Two males from Benguet, Luzon, average: Length, 356; wing, 216; tail, 131; culmen from base, 22; tarsus, 22.

Adult female.—Somewhat similar to the male but without a white band across the crop; fore breast light purple dulled by its slightly mealy look; held toward the light, it becomes green and away from the light, slightly metallic copper-red washed with vinous; rest of under parts much lighter chestnut than in male; wing-coverts glossy green, lesser and median coverts with blue spots at tips; interscapulars vinous and slightly mealy; lower back and rump green with touches of deep blue. The following notes are from an adult female taken in Benguet, Luzon: Iris with an inner white ring and outer pinkish ring; eyelids dirty white; bare skin about eyes blue-gray; bill deep rose-red, tip white; legs and feet rose-red, soles yellowish; nails brown.

Young.—Immature birds have the fore breast chestnut, uniform with the abdomen, thus not resembling the adult plumage of either sex; wings rich metallic green, or copper-red, without canescence and the primaries neither scooped nor cut as are those of the adult.

The plumage of the male and female in the gray-breasted fruit pigeon is so different that the sexes were long considered to represent distinct species. Grant, working on the material gathered by Whitehead, has shown that these differences are sexual and not specific and more recently collected material sustains his conclusions.

In habits these birds are quite similar to the slightly larger imperial pigeons or baluds. They feed on large seeds or nuts and are often found in considerable numbers in fruiting trees.
