Distribution. Garhwal, Kumaon, Simla and 8. Kashmir. 
Nidification. The Simla Streaked Laughing-Thrush breeds in 
great numbers throughout its range between 5,000 and 8,000 feet. 
The breeding season is very extended and eggs have been taken in 
every month from March to September, though probably those 
laid in July to September are second broods. The nests are made of 
dry grass, leaves, small pliant twigs and stems of plants, scraps of 
bracken and roots and they are lined with either roots or grass 
stems, generally the latter. They are bulky nests measuring 
roughly anything from 6" to 10” in outward diameter by some 
3" to 5” in depth, the ege-cavity being about 3” x23" or rather 
more. It is placed either in some thick bush in undergrowth or 
ona branch low down in a big tree, the Deodar being a special 
favourite and, though so big a nest, is always well concealed. The 
normal full clutch of eggs is three, rarely four and not seldom two 
only. They are unspotted blue-green in colour and have a 
smooth satiny surface with but little gloss. 100 eggs average 
25°6 x 184 mm.
