As now restricted this form of the Black-and-Red Broadbill is found over Tenasserim, Southern Siam, Annam and Cambodia, South to Singapore. This is a bird of the plains and sea-level, though it occurs in the mountains up to some 1,500 feet according to Robinson.
* I am still extremely doubtful as to whether this form should be maintained, but Robinson, who had for better material than I on which to work, considers it separable though “almost identical."
It is one of the most common of Malay Broadbills and is found not only in forest of almost any kind but in the vicinity of towns and villages and even in gardens and orchards. It also frequents Mangrove-swamps and often breeds in these latter.
Robinson (‘Birds of the Malay Peninsula,’ vol. ii, p. 161, 1927) says:—“In the Malay Peninsula the breeding season is from April to July or even later. A nest found by me in the interior of the Patani States on 22nd July was in secondary jungle, suspended from the projecting limb of a small tree about 8 feet from the ground, and looking like a mass of debris left there by a flood. The nesting chamber was formed in the upper portion of an elongate oval about 11 in. long and 15 in. in its greatest circumference, and was entered by a circular hole furnished with an cave. The materials were palm-fibres, twigs, creepers and aerial roots, with a few leaves. The inside was neatly lined with grass, and the eggs, three in number, were deposited on a bed of fresh green leaves. The nests are usually suspended over ponds or streams, generally the latter, at a variable height from the ground, not more than about 20 feet—sometimes as little as 8 or 10 feet. As a rule they are hung to the end of an aerial root or creeper, but sometimes they are attached above its termination. In the upper reaches of the Tahan river the nests were especially common, every hundred yards or so, together with those of the Larger Dusky Broadbill.”
To the above one must add that the nests are also sometimes built in Mangrove-swamps quite close to the sea. One set obtained by Coltart from the Waterstradt collection was accompanied by a note in German recording that “All our nests were large hanging affairs made of sticks and steins of plants mixed with grass, moss, leaves and roots. In shape they were round, with the hanging end drawn out. They were attached to the hanging branches of trees standing in swamps or at the edge of these.”
Hopwood says that the nests are usually lined with green leaves, which, however, are not renewed during incubation.
The breeding season is a long one, as Hopwood took nests and eggs from early March to August and Davison found a nest with young in the latter month.
The eggs number two or three and are very like those of Corydon but much smaller. The majority of eggs have the ground a pale dull salmon, freckled all over with pale reddish-brown or rather dark reddish-brown, in some eggs the freckles becoming larger and blotchy. The markings coalesce nowhere but are rather more numerous at the larger end. Another type has the ground creamy with the range of markings much the same as in the first type, while a third type is tinged with claret marked with deep claret-red.
In shape the eggs range from broad short ovals to long blunt ones. The texture is not fine and the surface is quite glossless.
Twenty-four eggs average 20.8 x 18.8 mm. : maxima 29.3 x 18.8 and 25.7 x 20.7 mm. ; minima 25.0 x 20.0 and 25.6 x 18.2 mm.
I have no information as to whether the male shares in the incubation, but as he has been disturbed from the nest and then shot it is to be presumed he does. Hopwood noticed that at some half-built nests both birds were about, apparently building,
