Mr. Berezovsky met with this species in the districts of 

 Si-gu-chen and Ming-djau. It is a rare bird, inhabiting the 

 more elevated portions of the mountains, where conifer- woods 

 abound, especially where there is an undergrowth of bamboo. 

 It was in pairs both winter and summer. It frequents

 it digs in the moss and dry leaves in search of food. It 

 roosts on trees, and at sunset the pair call to each other 

 with a loud note.
