314 TIMALIID®. 
It is placed either in a high bush ora small sapling in forest, either 
pine, fir or other kinds. The eggs vary from two to four and are 
a bright pale blue in colour with a few specks or spots of black, or 
reddish, or reddish brown. They measure according to Hodgson 
between 20-0 to 22°8 in length and between 15:2 to 16°5 in breadth 
but nine eggs in my own collection measure only 19°6 x 14:9 mm. 
Habits. This bird, like others of the genus, goes about in small 
flocks, haunting both the higher trees and scrub- and bush-jungle, 
though it keeps more to the former than the latter.

Siva castaneicauda Hume, 8. I., v. p. 100 (1877) (Muleyit); Blanf. 
& Oates, i, p. 209. 
Vernacular names. None recorded. 
Description. Differs from the last bird in the much greater 
extent of red on the tail; the sides of the head are blackish and 
the ring of yellow round the eye brighter and more conspicuous. 
Colours of soft parts. Iris deep brown; upper mandible brown, 
lower fleshy ; legs and feet dingy glaucous-blue. 
Measurements as in the last. I cannot find that the average 
size of the bill is any bigger. Oates says that the bill is much 
larger but gives no details. 
Distribution. The whole of Burma, throughout the hills from 
Tenasserim to the Chin and Kachin Hills and Siam. 
It is extremely difficult to define the limits of these two races. 
Birds from the extreme South and East of Burma are quite different 
from those of the Western Himalayas to Sikkim, but birds from 
Assam to W. Central Burma are intermediate, having the sides of 
the head little darker than in typical strigula, yet with nearly as 
much red on the tail as casteneicauda; the Chin Hills birds are a 
step nearer the latter, whilst those from Yunnan, the Shan States 
and all Eastern and Southern Burma are practically identical with 
that form. 
Nidification and Habits as far as is known like those of the last 
bird. A single egg taken by Mr. W. A. T. Kellow measures 
18-4 x 15:6 mm.
