BIRDS OF BRITISH BURMAH. 
shafts, barred above with dark brown, much paler underneath, where the 
qnills are white at the base of the inner web ; tail ashy brown, paler at 
tip, crossed with four bands of dark brown ; throat white, with a distinct 
black moustachial streak on each side and a broad median line ; chest clear 
tawny rufous ; rest of under surface white, broadly banded with pale 
rufous, each bar of this colour having a conterminous brown bar ; the 
thighs thickly barred with ashy brown without any rufous tinge ; under 
tail-coverts white ; under wing-coverts white spotted with brown or rufous- 
brown, and the axillaries similarly barred. (Sharpe.) 
Upper mandible and tip of lower dark brown or black ; remainder of 
the lower mandible plumbeous ; cere and gape lemon-yellow ; eyelids and 
orbital skin green; edges of eyelids yellow ; iris bright yellow ; legs yellow ; 
claws black. 
Length 16 inches, tail 8, wing 8' 6, tarsus 2*7, bill from gape 1*1. These 
are the measurements of a bird shot in Pegu. 
There are two races of this bird, a larger one (A. rufitinctus) and a 
smaller one [A. trivirgatus) . The bird I procured on the Pegu hills 
belongs to the smaller race ; but birds from Bengal and from Tenasserim 
belong, according to Mr. Hume, to the larger race. Mr. Gurney gives the 
measurements of a number of specimens c), and it appears that in 
A. rufitinctus the wings vary in length from 9*4 to 11 '5 inches, whereas 
in A. trivirgatus they vary from 7*5 to 9 inches. He states that the 
adults of A. trivirgatus differ from A. rufitinctus not only in their smaller 
size, but also in their very bright fulvous or rufescent tints on the upper 
breast and on the sides of the neck. 
I procured only one specimen of the Crested Goshawk in the evergreen 
forests of the Pegu hills in April, and Mr. Davison secured two specimens 
in Tenasserim. It appears therefore to be very rare in Burmah. 
It extends through the Indo-Burmese countries into India, where it is 
found along the Himalayas from Assam to Nipal, in Bengal, Southern 
India and Ceylon. It ranges into China, and it is met with in the Malay 
peninsula, Sumatra, Java, Borneo and the Philippine Islands. 
This Goshawk appears to frequent dense forests.
