ARCHETYPAL CRIES 139 



cirl-bunting (ibid.\ may well be deemed the primitive 

 form of a bunting-song. Likewise, the yell or pean 

 of the peacock may be a survival of a cry of alarm, 

 now adopted as a simple expression of defiance. 



As already stated (p. 9), I do not, except in 

 particular instances, refer to captive birds, and there- 

 fore I have not mentioned such interesting demon- 

 strations of family resemblance of voice as one 

 can easily perceive in zoological collections, and 

 especially in that at Regent's Park, London. There 

 one can hardly fail to be sensible of the strong family 

 resemblance between the voices of allied birds, of the 

 various races exhibited ; and, in regard to those 

 species which cannot be said to sing, this similarity 

 is of scientific value, since in those species imitation 

 seems to have less of that influence by which it so 

 powerfully affects the notes of captive song-birds.
