Many of the notes are almost indistinguishable from the notes of 

 Otoconipsa. I have often listened to these birds when they have been 

 feeding- in company with 0. flavlvcntrls, and have noticed that certain 

 of the lower notes used by them cannot be ascribed with certainty 

 to either bird. Again, a harsh note that they often use when irritat- 

 ed, is exactly like a common cry of Sypsipetes concolor. The song of 

 the male is a most typical bulbul's. Another trait that they show 

 in common with many bulbuls is their aptitude for imitation. 

 I have frequently heaid birds of this genus, more especially 

 aurifrons, imitating the cries of Shrikes and other birds. That 

 the common form of bulbuls do mimic other birds is a well known 

 fact. 



Sociability. — Oates states that these birds are to be found either singly 

 or in pairs. With this statement I most emphatically disagree ; every 

 year I see hundreds of these birds, and my experience tells me that 

 throughout the cold season Ohloropsis aurifrons and harduickll always, 

 and jerdonl generally, are to be found in flocks, these flocks being 

 often of considerable size. Nor by this do I merely mean to say that 

 many individuals are to be sometimes found feeding on the same tree, 

 for should they be frightened away, they still keep together and do 

 not disperse, as they would do had they no connection with one 

 another. Again, I have repeatedly watched a flock of these birds for 

 some length of time at a stretch, and can confidently assert that they 

 keep together when on the wing, whilst" outlying and straggling 

 birds repeatedly call to and are answered by other members of the 

 flock, which they always rejoin in a few minutes. 



Nldlfication. — Here I think is most plainly shown the position of 

 these birds amongst the Avifauna, showing the very strongest 

 affinity to the bulbuls. 



The nests. — I have seen many of C. jerdonl, hardtclckll, and aurifrons, 

 which are in every essential, almost, if not quite, indistinguishable from 

 nests of H. psaroides and concolor, a few being of the same type as 

 that of Hemiros flavala. 



Like the nests of Sypsipetes those of Chloropsis are generally 

 placed in some small horizontal fork of a branch of a high tree, and 

 like them are, more often than not, placed at a considerable height 

 from the ground, and close to the top or outside of the tree.
