TEE SIMLA STREAKED LAUGHING-THRUSH.
Trochalopterum lineatum lineatum griseicentior, Fauna B. I., Birds, 2nd ed. vol. i, p. 181.
This, the best known of all the Streaked Laughing-Thrushes, is extremely common throughout South Kashmir, Kuman, Simla States and Garhwal.
So common is this bird throughout its breeding range that no recent observer has troubled to augment Hume’s copious notes on its nidification. Hume says :—
“Next to the House-Sparrow the Himalayan Streaked Laughing- Thrush is perhaps the most familiar bird about our houses at all hill-stations of the Himalayas Westward of Nepal and throughout the lower ranges on which these stations are situated ; this species breeds at elevations of from 5,000 to 8,000 feet.
“It lays from the end of April to the beginning of September, and very possibly occasionally even earlier and later.
“So far as my experience goes, the nests are always placed in very thick bushes or in low thick branches of some tree, the Deodar appearing to be a great favourite. Those I found averaged about 4 feet from the ground, but I took a single one from a Deodar tree fully 8 feet up. The bird, as a rule, conceals its nest so well, that, though a loose and, for the size of the architect, a large structure, it is difficult to find, even when one closely examines the bush in which it is. The nest is nearly circular, with a deep cup-like cavity in the centre, reminding one much of that of Crateropus canorus, and is constructed of dry grass and the fine stems of herbaceous plants, often intermingled with the bark of some fibrous plant, with a considerable number of dead leaves interwoven in the fabric, especially toward the base. The cavity is neatly lined with fine grass-roots, or occasionally very fine grass. The cavity varies from 3 to 3.5 inches in diameter, and from 2.25 inches to 2.75 in depth ; the walls immediately surrounding the cavity are very compact, but the compact portion very rarely exceeds from .75 to 1 inch in thickness, beyond which the loose ends of the material straggle more or less, so that the external diameter varies from 5.5 inches to nearly 10.
“The normal number of eggs is three, although Captain Beavan cites an instance of four being found.”
Hutton and Marshall found the nest to be sometimes placed on the ground on banks, concealed among the grass-roots.
There is little one can add to the above, but some of my corre¬spondents give moss as a material used in some of the nests they have seen, whilst Osmaston found pine-needles used in the lining of some nests taken by him near Chakrata at 6,500 and 8,000 feet.
The birds breed in forest, open tree jungle, road-side thickets and even in gardens.
The eggs normally number three but four are not very exceptional, and several clutches of this number were taken by Dodsworth around Simla. They are greenish-blue in colour, more blue than green, and quite spotless, with a close, even and fairly fine texture, but only slightly glossy. In shape they are usually moderately broad ovals, very little compressed at the larger end, though, as one would expect in so common a bird, variations in shape of all kinds are constantly met with.
One hundred eggs average 25.6 x 18.4 mm. : maxima 30.2 x 20.1 mm. ; minima 23.1 x 17.3 mm.
