The Black-crested Yellow Bulbul was one of the most coramon birds in Siarn. It 

 was found on suitable localities över the whole country It most often frequents brush- 

 and scrubjungle, and it was never met with far inside the evergreen jungles. 



The young birds have the head and the long crest brownish olive with a faint pur- 

 plish gloss on the longest crest-feathers; chin black, but the throat is olive and of the same 

 colour as the upper parts of the body. The colour of the eye is whitish grey instead of 

 yellow as in the adult birds. The bill is much paler, almost horn coloured while in full- 

 grown birds it is pure black.

The Bengal Red-whiskcred Bulbul was very common in the Northern parts of the 

 country especially in the open and cultivated country. 



It is a very tame and familiar bird and is even found in the villages and towns. 

 Like the other Bulbuls it has a rather nice song and it looks quite a pretty bird when it 

 keeps its long black crest erect. 



The young birds are lacking the red patch below the eye and have the under tail- 

 coverts påle rosy pink.

The Large Cuckoo-Shrike is generally distributed över those parts of Siarn which 

 are covered with thin tree- or shrubjungles. On the top of the hills among the mixed 

 pine-and oak- forests it was the bird most of ten met with. Opposite to what is stated by 

 Dayison, I most often saw it associated in small parties, more seldom singlc or in pairs.
