but she lost a second. A finally captured and ate this too, 

 after a long chase, in which B also finally joined. The latter 

 bird (B) then occupied herself for some minutes in picking 

 up all the small pieces of white wing which now littered the 

 bottom of the cage, and in carefully handing them back to 

 A, w^ho threw each back to catch it in his throat, and seemed 

 much disappointed and surprised when, instead of arriving 

 there, it went floating off on the breeze. 



A fifteen -minutes' interval, then A ate 5 Amaurises (one 



A. ochlea, the rest A. lohengvla), the last three with marked 

 hesitation, and absohitely refused a sixth. B ate a D. 

 cJirt/sippns, but refused to touch a second. Five minutes 

 later, however, she snatched three in succession from the 

 forceps and bolted them down quickly, and just afterwards 

 two more. 



A half-hour interval (without food). A now absolutely 

 refused to touch an Amavris alhimacnlata, but ate ^ Danaida. 



B, after hesitation, snatched and ate — again with apparent 

 impatience and anger, however — two Danaida. On my 

 return immediately afterwards with an Amavris she was on 

 the floor of the cage devouring earth, and she refused the 

 A)naiiris. 



She now ascended to one of the higher perches, and re- 

 peatedly again refused the Ammiris^ finall}^ taking it in the 

 point of her bill (Did she remember its mimic of March 4?), 

 tasting it well, and dropping it. A at once most gallantly 

 descended^ picked it up in his bill, and climbed up again 

 with it to B, placing it in her bill. She could no longer 

 refuse a dainty so courteously offered, and swallowed it at 

 once — again like a pill, however ! — and a second in like 

 manner. 



A now ate two dead Amauris alUmandata. tastinir each 

 very thoroughly in the point of his bill before doing so. I bad 

 no more live Danaines, so discontinued the experiment. 



532. March 15. — I fed both birds on locusts till they 

 would accept no more. Soon afterwards B ate a Danaida 

 chrysippus, but rejected a second after nibbling it in the 

 point of her bill for some time. A ate readily 5 Danaida
