Experiments with various Birds (on more liberal diet) Series E. 



I. I offered two Terias to the birds ; a Liothrix took and left one, 

 then, with no great relish, apparently, ate the other. Meanwhile an- 

 other Liothrix took and left the first specimen. This was not eaten 

 immediately at any rate, but next morning I did not see it. 



II. I put many " protected " butterflies into the aviary, mostly 

 Euploea and Danais limniace, but also a D. chrysippus or two and a 

 Papilio aristolochise. The Liothrix soon attacked the Euploeas, and a 

 Yellow- vented Bulbul took a D. limniace, which it ultimately swallowed, 

 I believe, after much trouble. I also saw it with an Euploea, and (I 

 believe the same bird) with another D. limniace. 



I put in a Gatopsilia, which was soon taken, though (as above 

 stated) there were many other butterflies, by a Liothrix, which was 

 tearing it to pieces, when her own mate forcibly drove her off, and after 

 pecking at the butterfly with no great relish, left it. I saw an abandon- 

 ed Euploea close by, and this morning I have seen Liothrix eating these. 



A Zosterops took an Euploea, and picked it a bit but then dropped 

 it. 



The Chloropsis attacked the butterflies, but did not seem able to 

 manage them. But later in the day I saw him swallow with some 

 trouble the body of an Euploea. Only a few butterflies were now left ; 

 of these an Euploea and a D. chrysippus were feeding on the birds' fruit. 

 The Gatopsilia was now goue. 



I saw a Liothrix leave the body of an Euploea after stripping off the 

 wings. 



Later on, towards evening, I gave the Chloropsis a very small non- 

 warningly-coloured butterfly, which he ate, and after that a Terias, 

 which he also ate. 



I offered him two heads of D. chrysippus, the first of which he 

 flicked away, and the second he only just touched once. He then 

 immediately took and ate the head of a Gatopsilia, I could not get him 

 to touch the heads of two Euploeas, but it was near roosting-time. 



One Euploea and the P. aristolochise were still uneaten. I took out 

 the Euplo3a and put in a Gatopsilia, which was soon taken and disposed 

 of by Liothrix, apparently with no great relish. 



£11. Next day in the morning while there were still maggots 

 in the cage, gave the Chloropsis a skipper, which he ate with difficulty, 

 getting it the wrong way at first. In the evening, the Papilio aristolochise 

 put in yesterday had its wing3 pulled off, but was still uneaten. I 

 put in another, and several non-mimetic P. polites. The birds did 

 not seem eager for them, although a Liothrix had taken a non-warn- 

 ingly-coloured butterfly readily, before they were put in.
