THE BLUE-HEADED ROCK-THRUSH. 
9 
Arrakan hills, where Mr. Blyth first got it I believe. I have not observed 
it in Pegu. Capt. Wardlaw Eamsay shot it in Karennee at elevations 
from 1500 to 3000 feet. Mr. Davison met with it in Tenasserim near 
Pahpoon and Mooleyit mountain, where it appears to have been rare. 
Capt. Bingham records it from the Thoungyeen valley, where he procured 
one specimen. 
It inhabits the Himalayas from Sikhim to Assam, and it has been ob- 
served in the Khasia hills. In the British Museum are specimens labelled 
as having come from Upper India and Siam ; but I do not think these 
labels trustworthy. 
A^herever this Thrush occurs it is probably a resident. Its food consists 
of insects and, like most Thrushes, it feeds principally on the ground.
