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 11 th. —A fresh Babbler confined alone pulled about an 
Euproctis moth for a time, but I found it left afterwards. I gave him 
separately an abdomen which he had knocked off, but did not see it 
eaten. 
December 12 th. —Babbler appeared to eat a bit of an Euproctis 
abdomen. 
December 13 th. —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 34 th. —A Babbler ate a Papilio demoleus* whole, but did 
not eat a Danais clirysippus and Delias eucharis , though descending 
from his perch to eat a Catopsilia. 
December 15 th. — 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 genutia, D. chrysippus , 
and Delias eucharis. Two Euproctis 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 1 6th. —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 
* erithonius auctorum.
