1897.] F. Finn — Experiments with various Birds. 617 



Next day all the butterflies were gone (I did not notice the 

 Delias eucharis) but the Papilio aristolochise, which was not even hurt 

 till the afternoon, when a Bulbul killed it, and some bird, I think, 

 afterwards ate the abdomen. Yet the birds had no insects to-day. 

 The Liothrix often pecked at the wings lying about. 



VI. I put into the aviary a number of butterflies, the non- 

 warningly and warningly-coloured species being fairly equal in number, 

 the former comprising Catopsilia, Junonia, &c, and the latter being 

 chiefly Danais chrysippus. 



The Liothrix only attacked non-warningly-coloured species at first, 

 as far as I could see, and the Button-quails also seemed to like these 

 best, for I saw one swallow a Catopsilia, and they eagerly pursued 

 Liothrix which had one of these or another non-warningly-coloured 

 butterfly in their possession. On the other hand, I saw a D. chrysippus 

 worried by one, but I am not sure that it was eaten. 



The Common Bulbuls made no attempt to eat any butterflies but 

 one D. chrysippus, which was taken and I think eaten by this species, 

 even with other butterflies about. I saw the Red-whiskered Bulbuls 

 eat two D. chrysippus ; I forget whether at this particular time there 

 were non-warningly-coloured butterflies about, but when there were 

 these birds made no attempt to eat them. 



The Liothrix afterwards attacked and ate some of the warningly- 

 coloured kinds ; I saw an Euplcea and a D. genutia taken and eaten 

 even when two Elymnias undularis <$ were in the aviary, I had put in 

 two males of this species and one female (in bad condition and much 

 torn) with their upper surface displayed ; but the first bird that came 

 (a Button-Quail) chose the female first. 



The Bulbuls had had no food for two hours at least, and ravenously 

 devoured part of a plantain put in. When the birds went to roost 

 the only butterflies unhurt were a Papilio aristolochias and some 

 J), chrysippus ; a P. demoleus lay dead. 



A P. polites was soon killed, though I did not see it done, and 

 I think a Button- Quail ate it. 



VII. Next morning all the butterflies appeared to have been eaten 

 but the Papilio aristolochise, which was still alive, though in the after- 

 noon I found it dead, but uneaten. 



About 5 p.m. I put in first a Delias eucharis, which was attacked 

 and devoured whole by a Button-quail, which had yet not eaten the 

 P. aristolochise. 



I then put in another P. aristolochise and a P. polites, together. The 

 latter was almost immediately attacked by the Liothrix, and I think 

 partly eaten, while a Button- Quail swallowed the remainder. The
