Delias eucharis (minus abdomen) was mauled and left. A female 

 Hypolimnas misippus was taken, and part at least was eaten. The birds 

 take all butterflies one gives them and batter them a bit. Some of 

 the Danaids may have eventually been eaten. 



Next day I released these Babblers, not having got any very 

 conclusive results from them. They did not seem very keen on but- 

 terflies, and were perhaps not healthy. Moreover it was difficult to 

 observe them in a hutch. 



Experiments with Babblers in confinement. Series B. 



December \lth. — A fresh Babbler confined alone pulled about an 

 Euproctis moth for a time, but I found it left afterwards. I gave hint 

 separately an abdomen which he had knocked off, but did not see it 

 eaten. 



December 12th. — Babbler appeared to eat a bit of an Euproctis 

 abdomen. 



December 13th. — This Babbler, with another, and other birds being 

 now in a small aviary, with ^ inch-mesh netting, I saw one of them 

 seize an Euproctis. A Babbler also pulled another of these insects 

 to pieces, but did not eat it as far as I saw. 



December lith. — A Babbler ate a Papilio demoleus* whole, but did 

 not eat a Danais chrysippus and Delias eucharis, though descending 

 from his perch to eat a Catopsilia. 



December \5th. — The birds in the aviary being hungry, I put 

 in some butterflies. I saw a Babbler eat a Terias. Later on, after 

 the birds had had some food (meal moistened with water) I put in 

 more butterflies, and saw a Babbler eat a Danais genutla, D. chrysippus, 

 and Delias eucharis. Two Eitpioctis were eaten by Babblers. Two 

 Danais genutia were seized and torn to pieces, and part of one was 

 apparently eaten by the Babblers, which showed some signs of apparent 

 dislike ; of two D. chrysippus then given, one was torn up and eaten, 

 and the other torn up and rejected, by a Babbler, which then took and 

 left a D. genutia and Delias eucharis, and then went and ate some rice. 

 After this I released the other birds in the aviary, as they had no chance 

 with the Babblers. About this time I added a third specimen of the 

 latter. 



December 16th. — One of the Babblers took and ate nearly whole, 

 after much rubbing and pecking, a caterpillar rather larger and much 

 hairier than that of the Buff-tip (Pygaera bucephala). I think this is 

 the larva of whose hairs I recently got my fingers full. The bird had
