It utters a loud whistling note, which may be heard more 

 frequently in the early morning. This is one of the first 

 sounds which attracts the traveller's attention on entering 

 the Kina Balu region. 



I saw a nest which was built in a long tangled mass of 

 creepers some 30 feet from the ground ; it was com- 

 posed of dead leaves and roots, and contained one bright 

 greenish-blue egg: this was on the 17th of March. Iris 

 dark lake-red; bill pale orange-yellow ; skin round d^e 

 bright king's yellow ; feet paler yellow.]

I have already described the sexes of this species (/. c.) and 

 the curious young bird. 



[Met with on my second expedition in the old forest at 

 4000 feet. It has aloud booming call-note, and creeps about 

 in the trees much like Bhinocichla treacheri, from which it 

 would be difficult to distinguish it but for the white marks 

 on the wings of that species. This bird is by no means 

 common and seems to be local. The young bird, curiously 

 enough, has the crown of the head feathered to the base of 

 the bill, but has a large space of bare skin behind the eye, 

 as well as bare spaces on the neck. The feathers are softer, 

 and the wings of a lighter brown than in the adult. 



The adults had the iris dark brown, the bill vermilion, the 

 head quite bald, and the skin of a brownish greenish-yellow, 

 more yellow at the base of the bill ; bare skin on neck dull 

 bluish green ; feet brownish yellow.
