THE ASSAM ASHY LAUGHING-THRUSH.
Ianthocincla cineracea cineracea, Fauna B. I., Birds, 2nd ed. vol i, p. 156.
This bird is common in the hill ranges of Assam South of the Brahmapootra, extending South through Manipur to the Chin Hills, but not East to the Lakhimpur district. It breeds from 5,000 feet upwards but generally over 6,000 feet. In North Cachar I saw a few birds on the high peaks adjoining the Naga Hills but I never succeeded in finding their nests, and they probably retired to still higher hills for this purpose.
In 1909 Col. Tytler found them breeding in some numbers near Kohima between 7,000 and 8,000 feet and took several nests. These he describes in a letter to me as “rather deep, compact cups of moss, leaves, roots and grass, bound round with weed-stems and tendrils and lined with roots. The outer measurements are roughly 6''.8" x 2.3/4".3.1/2" and the inner cup measures about 4" x 2". The eggs are equally often two or three, never four. I have taken most nests from damp forest, where they are built in thick bushes, always placed quite close to the ground, often within a couple of feet. The bird sits very close and is easy to identify.”
In the Chin Hills it is one of the most common breeding birds down as low as 4,500 or 4,000 feet. Mackenzie, Hopwood and Macdonald saw many nests and eggs and the first-named gives the following account of its breeding :—
“This is the Common Laughing-Thrush of the district, being exceedingly abundant between 4,000 and 6,000 ft., and breeding in the raspberry vines and thickets near the villages. We obtained a large number of eggs and nests at the end of April and beginning of May. The laying season seems to extend for about a month, as we got both hard-set and fresh eggs almost every day.
“The nest is a small and flimsy copy of that of G. pectoralis, and is generally fairly conspicuous ; the bird obliges by sitting on it until you almost touch her, thereby rendering identification easy. The nests were generally placed in low thickish bushes, 3' to 6' high, and were made of grass stems and fine twigs, not very tidily put together, as all the ends stick out. The lining is of fine black and brown stems and a few moss roots. In shape it is a hollow saucer, about 4.1/2" across and 2" deep externally, and 3" x 1.1/2" internally.” The eggs are a soft, fairly deep, unspotted blue, with a very beautiful silky texture. In most eggs there is a faint greenish tinge and in one clutch, taken by Mackenzie, a distinct yellow-green tint, evidently abnormal and due to some defect in the bird laying them.
One hundred and fifty eggs average 25.3 x 18.6 mm. : maxima 29.25 x 19.2 and 27.5 x 20.0 mm. ; minima 23.0 x 18.0 and 23.2 x 17.3 mm.
