THE ASSAM RUFOUS-CHINNED LAUGHING-THRUSH.
Ianthocincla rufogularis assamensis, Fauna B. I., Birds, 2nd ed. vol. i, p. 150.
The range of this race is from West to East of the Assam Hills South of the Brahmapootra, East to the Chin Hills. I found this bird breeding in fair numbers throughout the Khasia and North Cachar Hills between 3,000 and 6,000 feet. Most nests were placed below 4,500 feet in these hills but in the adjoining Naga Hills they are certainly resident breeding birds at the higher elevations and probably up to about 7,000 feet above Henema.
The most usual site selected for the nest is one in deep forest, generally of lofty trees with plenty of green undergrowth ; at the same time they like to get near to some natural opening, such as the banks of a stream, small or big, or an open glade in which both trees and undergrowth thin out and let the sun through. Close to such an opening they choose some bush or tree, or a clump of raspberry or other vines in which to build their nest, at any height between 2 and 20 feet. The nest is like that of its cousin, already described, but the materials used are much more diverse, though the tendrils of a little creeping Convolvulus nearly always form, an important part of them. Most nests are rather deep cups, about 6 inches in diameter and about 4 to 6 inches in depth, with an egg-cavity about 2 inches less each way. They are composed of soft pliant twigs, roots, leaves, many scraps of bracken and then the stiffening and binding of the fabric with the tendrils. The lining is of fine roots.
The number of eggs laid is generally three only but sometimes there are four, and occasionally two only are laid. They are the same pure glossy white as those of the preceding bird, and forty of them average 26.5 x 18.9 mm. : maxima 29.2 x 19.7 and 26.3 x 19.9 mm. ; minima 24.3 x 18.0 mm.
They are normally rather late breeders for this species and I have taken more eggs in May than in any other month, but they breed regularly from late April to the end of July.
These birds can nearly always be watched and identified on the nest with ease and I have often had them sit and watch me from a few paces with wide-open unblinking eyes and then, as one steps forward, they tumble noiselessly off the nest and vanish, with a low chuckle, into the undergrowth.
Both sexes take part in incubation.
