136. Gairulax gularis

(136) Garrulax gularis gularis (McClell.)
The Cachar Yellow-breasted Laughing-Thrush.
Garrulax gularis, Fauna B. I., Birds, 2nd ed. vol. i, p. 152.
This bird is restricted to Assam, South and East of the Brahma¬pootra. from Cachar to the Dafla Hills and East Lakhimpur. It occurs in Manipur and Mackenzie thought he saw it in the Chin Hills.
I found this bird breeding freely in North Cachar between 4,000 and 6,000 feet, rarely a little lower. The nests are like those of Garrulax moniligera, but they are more bulky and better finished off. In most nests the greater portion of the materials consist of bamboo-leaves, other articles being used such as dead leaves, moss- and fern-roots, sometimes coarse bamboo-roots and stems of weeds and, almost invariably, a great number of tendrils, in some few eases these forming the bulk of the nest. The lining consists of coarse moss- and fern-roots mired with leaf-stems and a few stalks of weeds. The largest nest I ever took was one which was found by a jungle path in a mass of creepers, half resting on or against a dead stump. This nest was fully 7.1/2 inches across, whilst the inner wall, i. e., that against the bank, was about 7 inches deep and the outer wall about 5 inches.
The situations selected for breeding purposes differ greatly. I have taken nests from practically off the ground and others from saplings and small trees possibly up to 25 feet. Most nests, however, will be found in bushes somewhat under 4 feet.
The birds breed both in deep forest or, less often, in comparatively
open forest, or in bamboo and scrub-jungle. The favourite position is in evergreen forest beside some stream.
The eggs may be either pure white or pale blue, much paler than the eggs of the Necklaced Laughing-Thrushes. Occasionally the eggs are almost white, with just the faintest tinge of blue, but such eggs are exceptional. The texture is smooth and fine but not glossy, and they hare a slight sheen which separates them from other similar coloured eggs. In shape they are rather long ovals, sometimes pointed at the smaller end.
Two or three eggs form the usual clutch, generally three.
One hundred eggs average 29.2 x 20.5 mm. : maxima 31.0 x 19.8 and 29.0 x 21.7 mm. ; minima 25.5 x 19.6 and 27.8 x 19.2 mm.
Thes earliest birds commence to breed at the end of April, while the latest lay in. the middle of July, but the very great majority of eggs are deposited in May.
They are not demonstrative birds at any season and, when breeding, are very furtive in their movements. Although they sit close and do not move off their nests until the last moment, it is difficult to get a glimpse of them as they slip off. They return very quickly, however, and are easy to trap on their nests. The Nagas of the Patkoi range above Margherita often brought in the nests and eggs with the parents, which they had secured in this manner. Both sexes take part in incubation, so both were captured.
