(146) Ianthocincla austeni austeni (Godw.-Aust.).
The Cachar Brown-capped Laughing-Thrush.
lanthocincla austeni austeni, Fauna B. I., Birds, 2nd ed. vol. i, p. 160.
This Laughing-Thrush is only found in the higher ranges of hills South of the Brahmapootra, generally above 6,000 feet, less often down to 5,000, and, very rarely, down to 4,000. It breeds on the highest ridges of the Khasia Hills and thence more commonly into the Naga Hills up to 9,000 feet. In North Cachar it is rare and I never met with it until I visited the high ranges towards Henema in the Naga Hills. There, at about 5,000 to 7,000 feet, I saw pairs in dense forest but failed to find their nests.
In the Khasia Hills they are restricted to the forests composed of Oak and Rhododendron on the highest peaks above Shillong about 6,000 feet, or to the very tops of the highest hills near Cherrapoonji, which range over 4,000 feet. Everywhere, however, it is rare in this district, though common in the adjoining Naga Hills. I never found it nesting in Pine woods, except in broad, open ravines or along the banks of streams where the Pines were replaced by other trees.
The nests range from, rather flimsy, carelessly put together cups of tendrils, roots and leaves to compact, well-built cups of moss, leaves, bamboo-spathes, grass etc. Tendrils form a part of almost every nest and one or two are built entirely of this material with merely a lining of roots and bents. In many nests the main inner portion consists of bamboo-leaves held together with a few weed-stems or long roots. Smaller and finer roots always form the lining, though these may be mixed with a few bents. Generally the roots are all fine red roots of lichen and moss but sometimes black moss-roots are used.
I have found some nests within a foot or two of the ground in tangles of raspberry vines, bracken etc. Many were placed in high bushes up to 6 feet or rather more, whilst a few were built in small Oak or Rhododendrons up to 10 feet from the ground.
The breeding season starts in the middle of April and I have taken incubated eggs on the 19th of that month. They lay all through May and in smaller numbers in June, though I have taken eggs as late as the 1st of August.
The full clutch is generally three, but sometimes four eggs are laid and, occasionally, only two are incubated.
They are white eggs, resembling those of the Rufous-chinned group in shape and texture, though I think the surface may be on the whole very slightly closer and more glossy.
Forty-six eggs average 26.3 x 19.0 mm. : maxima 28.1 x 19.6 and 27.0 x 21.0 mm. ; minima 23.1 x 19.6 and 25.7 x 18.0 mm.
