Whole head black, except a few white feathers behind the eye; a white collar round the neck, narrow at the back, wide on the lower throat and neck; upper plumage black, the outer webs and tips of the scapulars yellow and the centre of the back, rump and upper tail-coverts boldly marked with bright yellow; tail black, with a yellowish-white sub-terminal spot on the inner web, increasing to a band on the outermost; wing-coverts black; quills black, the primaries with a white patch at the base of all but the outermost on the inner web and the outer web of the outermost' on the basal edge; a broad black band across the upper breast; breast and upper abdomen pale claret-pink, changing to bright yellow on the posterior flanks, vent and under tail-coverts ; axillaries and under wing-coverts yellow and black; edge of wing yellow ; thighs black.
Colours of soft parts. Iris lemon-yellow to golden yellow; upper mandible smalt-blue to almost black at the base, bright green on the terminal third, sometimes running in streaks into, the basal colour; lower mandible smalt-blue; legs and feet fleshy-pink to horny-brown.
Measurements. Total length about 170 mm.; wing 73 to 82 mm.; tail 44 to 50 mm.; tarsus 22 to 24 mm.; culmen 16 to 18 mm. long and 15 to 16 mm. broad at the gape.
Female. Similar to the male but with a less perfect black gorget.
Young birds have the forehead and a line to the eye yellow ; there is no black gorget; the chin and throat are yellowish-white and the under plumage pale and dull with indications of dark streaks all over the breast and flanks.
Distribution. Peninsular Burma and Siam, South to Malay States, Sumatra and Borneo.
Nidification. A. nest and eggs taken by Mackenzie appear to be exactly like those of E. j. javanicus. The two eggs measure 23.5 x 17.0 and 23.5 x 16.5 mm.
Habits. According to Davison this Broadbill is very similar to other Broadbills in its habits and like them is chiefly insectivorous in its diet and often catches its prey on the wing. The note is said to be similar to that of E.j. javanicus but shriller.
