VALIDITY OF SOME FORMS OF MIMICRY. 7 17 



Subfam. BRACHYPODINiE. 



18. The Southern Indian Bulbul. Hypsipetes ganeesa. 



" Its diet consists of fruits, seeds and berries it, 



however, also feeds on insects, and I have observed it occasionally 

 dart at them from its perch, although its usual manner of cap- 

 turing them is to seize them from the branches of trees, to which 

 it will sometimes cling after the manner of a Tree-creeper." 



19. The Madras Red-vented Bulbul. Molpastes hcemorrhous. 

 " Feeds mostly on fi-uit." {Oates.) 



20. The Yellow-browed Bulbul. lole icterica. Indigenous. 

 " I have found it to be more insectivorous than frugivorous." 



" It wanders about in small flocks, feeding almost entirely on 

 fruits and seeds." {Bourdillon.) " In all the specimens I have 

 examined I have found fruit only in its stomach, but from the 

 strong bristles at the base of the bill I suppose it may, at certain 

 seasons, partake of insects." {Jerdon.) 



21. The Black-capped Bulbul. Pycnonotus melanicterus. 



Indigenous. 

 " It is chiefly insectivorous, small seeds are sometimes devoured 

 by it, and I have found snails of some little size in its stomach." 



22. The Yellow-eared Bulbul. Kelaartia penicillata. In- 



digenous. 



23. The White-browed Bulbul. Pycnonotus luteolus. 



" It is both insectivorous and frugivorous, chiefly the latter, and 

 thei-e is nothing to which it is more partial than the seeds or 

 berries of the latana plant." 



Bulbuls are very frequently kept as cage birds, and have perhaps 

 been more often experimented with than any other ti'opical bird. 

 Those I kept yeax's ago ate any butterfly given them, and I think 

 it is now generally acknowledged that those species which are 

 known to be insectivorous also attack butterflies, but they show 

 no discrimination in eating them. 



Fam. DiCRURiD^. Drongos or King Crows. 

 All the Drongos are known to eat butterflies. 



24. The Black Drongo. Dicrurus ater. 



" The principal food consists of coleoptera, grasshoppers, winged 

 termites, of which it is very fond, and ticks, which latter it takes 

 from cattle. It has been known to devour small birds." 



25. The Indian Ashy Drongo. D. longiccmdatus. Migratory,
