Feathers of forehead, crown, back, and rump blackish-brown, bordered or washed with yellowish-citrine, those of nape and upper back whitish at the base. Sides of head lighter, shading gradually to olive-buff on throat, breast, and sides; middle of abdomen still lighter, ivory-yellow. Upper wing-coverts and secondaries fuscous-black (freshly molted feathers blacker) narrowly edged with olive-ocher. Primaries similar, but yellowish border almost entirely lacking; both primaries and secondaries fading to pale olive-buff on their inner edges. Under wing-coverts colored like the breast, but with faint dusky shaft-streaks. Feathering of flanks ivory-yellow, with strong blackish median lines. Two middle pairs of rectrices dull blackish, 3rd pair whitish, with a small blackish spot on the outer edge close to the tip, and a larger concealed black spot on the inner web towards the base; the 3 remaining pairs of rectrices white. The long median pair of under tail-coverts blackish, the next pair similar, but margined with whitish, the remainder ivory-yellow with faint shaft-streaks of dark brown. Upper tail-coverts fuscous-black, bordered with amber-yellow.[1] The bill, nostril, and feet resemble those of _Indicator indicator_, but the bill is somewhat stouter, while the wings and tail are shorter. The 9th (outer) primary is intermediate in length between the 6th and 5th; the 7th and 8th are longest. Iris bright brown, naked edges of eyelids grayish-brown; bill dusky-brown; feet dull grayish-green. Length (skin), 160 mm.; wing, 93.5; tail 56; bill (culmen from base), 13.5; metatarsus, 14. This unique specimen was shot by the describer from a tall tree in the forest, where it was accompanied by one other of its kind. The sexual organs were somewhat enlarged; the stomach filled with beeswax, mixed with small pieces of insects. Apparently this species is not in the habit of leading men to beehives.
