470 Mr. A. G. Butler on the Effect of offering 



the Wryneck and Sedge- Warbler ; Epeira diademata bj 

 Nightingales, Indigo Finch, and Chaffinch, and a small one 

 by Cordon-bleu (Red-eared African Waxbill). The Wax- 

 bills never refuse spiders. 



29th August. 



Caterpillars of Ganoris hrassicce given to Nightingales ; 

 killed but not eaten. The Song-Thrush and Starling, how- 

 ever, ate them without hesitation. Caterpillars of G. rapce 

 again eaten by Wryneck. 



30th August. 



Caterpillars of G. hrassicce eaten by Missel-Thrush, Song- 

 Thrush, and Starling, rejected by Indigo Finch ; again killed 

 but not eaten by Nightingales ; caterpillars of G. rapce eaten 

 by all my soft-billed birds, by the Indigo Finch, and 

 Chaffinch. A caterpillar of G. hrassicce was rejected by a 

 pair of Orange Weavers, but they were both at the time in a 

 dying condition. 



31st August. 



Caterpillars of G. hrassicce killed and the contents (but 

 not the skin) eaten by Bulbul ; swallowed entire by Missel- 

 Thrush ; eaten, apparently without relish, by Song-Thrushes ; 

 killed but not eaten by Blackbird ; caterpillars of G. rapce 

 eaten as before by all soft-billed birds, indigo Finch, and 

 Chaffinch ; small spider ( Tegenaria^ sp.) eaten by Sedge- 

 Warbler ; caterpillars of Mamestra hrassicce were eaten by 

 many of the birds, but I have never known this species alto- 

 gether refused by any insectivorous bird in good health ; the 

 Wryneck alone objects to the brown variety, but he will get 

 over this in time I believe. 



4th September. 



Largest-sized Tegenaria domestica given to Nightingales, 

 Missel-Thrush, and Bulbul, and eaten with the greatest 

 relish ; large specimen of Epeira diademata eaten by Wax- 

 bills ; earwigs eaten by Nightingales. 



6th September. 



Gave caterpillar of Cossus ligniperda to Missel-Thrush, 

 which tasted but did not relish it ; took it away and offered 

 it to Blackbird, which ate it at once and made the whole place 

 smell horribly. Gave caterpillars of Ganoris hrassicce to 

 Missel-Thrush and Starling ; the former swallowed them 

 whole, the latter tasted and then rejected them.
