This thrush, which occurs throughout the year in the dense, moist 

 evergreen of the provinces west of (and including) the Khun Tan 

 chain, is probably fairly common, although, owing to the nature 

 of its haunts, it is seldom seen. It has been taken on Doi Khun Tan 

 at 3,000 feet ; on Doi Ang Ka, at 4,400 feet ; on Doi Suthep, between 

 4,500 and 5,500 feet ; however, I have collected, December 26, a speci- 

 men at the very foot of Doi Pha Horn Pok, which indicates that it 

 may occur in suitable forest at whatever elevation, at least during 

 the cold weather.

 ravines and along small streams, keeping normally to the ground 

 but, when alarmed, flying onto some low branch, whence after a mo- 

 ment, it disappears silently into the darkness of the jungle. An 

 example from Doi Ang Ka had been feeding on large, hard fruits. 



Smith had the good fortune to take a breeding female, with her 

 nest and young, on Doi Hua Mot, August 28, 1934. Kiley (1938) has 

 commented on them as follows : "A nest with three nestlings with the 

 eyes unopened was taken. It is a large flat nest composed entirely of 

 pine needles, except for a narrow rim of mud mixed with a little moss

 from the ground in a tree. The nest cavity is very shallow, and the
