640 F. Finn — Experiments with, various Birds. [No. 4, 



P. polites remained, but in such a position that I suspected ants might 

 have eaten them. 



I think the Danaids and Euplcea were all eaten later on. 



XV. I put in three Catopsilia, and one specimen each of Danais 

 chrysippus and limniace and Euploea. All were dead and rather dry. 

 But although maggots and fruit were available, the Chloropsis 

 immediately, and the Liothrix soon after, attacked the Catopsilias. I 

 think part of them was eaten, but afterwards I found one body, and 

 saw the Chloropsis drop its prey or part of it, which the Red- whiskered 

 Bulbul seized, but also dropped, I think, for I found a dry crushed 

 thorax. None of the Danaines were eaten at present. 



The Chloropsis was apparently eating the rejected body of the 

 Catopsilia when a Liothrix took it. 



XVI. Next day, there being plenty of maggots, fruit, and bread- 

 and-milk in the aviary, I put in nine non-warningly-coloured butter- 

 flies, and one specimen each of Danais chrysippus, genutia, and limniace, 

 'Euploea, and Acrsea, all dead or disabled. 



They were not touched immediately, but before long a Liothrix 

 took a non-warningly-coloured one, and then another did the same. The 

 latter dropped its prey, and I found the abdomen on the floor, which 

 the Chloropsis ate when offered, after much pinching. 



The Red-whiskered (apparently) and Common Bulbuls then eacli 

 took a non-warningly-coloured specimen and ate it. The former bird 

 rejected one non-warningly-coloured specimen which was rather dry, but 

 then ate another. I then saw a Liothrix eat part of a non-warningly- 

 coloured specimen. 



The Common Bulbul then ate the D. genutia, when it might have 

 taken a Catopsilia. This last specimen, the small dried one, and an 

 Elymnias undularis tf were the only non-warningly-coloured ones left. 

 The Liothrix on this occasion behaved much as I have seen done with 

 " protected " butterflies, pecking their prey about much. The Red- 

 whiskered Bulbul pecked and refused the Acrxa, which specimen had 

 been also refused by the Liothrix which had refused the small dry 

 non-warningly-coloured specimen. 



The Common Bulbul descended and ate the Catopsilia, which had 

 been dropped by the Chloropsis, which in turn had got it after a 

 Liothrix. The same Bulbul then flew down and pecked the Elymnias, 

 which I hud moved nearer the " protected " specimens, but then flew 

 up, perhaps frightened. This Elymnias was now apparently the only 

 non-warningly-coloured specimen left. I now saw it pecked and left 

 by tin; lied-whiskered Bulbul, which had previously been eating some 

 fruit near it. Then a Liothrix took and tore it, and then dropped it,
