Birds in Relation to their Pre>/. 51 



Ajjiauris lohengula (blacky with white spots in fore wintr and 

 a large buff patch in the hind wino) fluttered violently 

 against the bars, greatly exciting the bird's curiosity. The 

 latter finally took advantage of a lull in its movements to 

 edge up to it and seize it by a wing, and, the wing holding, 

 as only the wing of a Danaine or Acreeine would have done, 

 to transfer it to her foot and pick it to pieces. The abdomen 

 was swallowed at once, the thorax dropped, but even this, 

 with one fore-wing attached, was also swallowed readily 

 enough on being reoffered. 



" And then the troubles . . . ." Almost immediately after 

 swallowing the Aniauris the bird commenced to rub her bill 

 violently against the perch and the sides oE the cage, and 

 continued to do so frequently daring the next four or five 

 minutes. Then she held her head down and ejected a dark- 

 looking fluid followed by a small pellet compos'ed of the 

 abdomen and the thorax with a fore-wing. She strained 

 twice afterwards, bringing up more of the dark fluid. 



Twenty minutes later I captured a Papilio dardanus, 

 female form cenea, and, removing the wings of one side to 

 prevent possibility of escape, placed it in the cage. Its 

 movements were sluggish, but the bird edged up to it almost 

 at once, and after a certain amount of hesitation (the result, 

 doubtless, of its resemblance to Amanris lohengula) took it. 

 She also showed a good deal of hesitation or suspicion while 

 tearing off the wings, and twice interrupted the operation 

 and ate a migratory locust. Finally, however, she did 

 complete the stripping, cut off" and ran the thorax through 

 her h\\\, doubtless tasting it well, artd then swallowed it 

 without further hesitation. Then with no hesitation or 

 tasting at all she just tossed up the abdomen with a small 

 portion of the thorax and a hind wing attached, caught it in 

 the back of her bill, and swallowed it too. I watched for 

 half an hour for bad results, but the bird brought nothing 

 up and was particularly lively and cheery all the time. She 

 is a great deal less timid since she lost her companion«. 



I then offered an Amauris ochlea, a Danaine with strongly 

 contrasted black and white i)attern and a gaseous smell that
