COCK-OF-THE-ROCK— BELL-BIRD 17g 



The first of the two large groups just referred to 

 form the 



Sub-order — Clamatores 



The birds herein placed, though regarded as non- 

 singing birds, yet include a few species with melodi- 

 ous voices; though none have a song comparable to 

 that of such songsters as the Nightingale or the 

 Thrush or the Mocking-bird. But it is not, as has 

 been said, the quality of the song so much as the 

 number of song-muscles and their arrangement that 

 is considered in this connection. 



Included among the Clamatores are the birds 

 known as the Broadbills, or Eurylasmidee, of East 

 India, some of which are very beautiful. Very 

 closely allied to some of these are the Cotingas, of 

 which the most gorgeous is the Cock-of-the-Rock, a 

 native of South America. This bird is shy and 

 solitary in habits, living among the rocks along the 

 river-banks. The whole plumage is brilliant orange- 

 red, with the exception of the primaries, which are 

 brown with yellow tips. A thick crest of feathers runs 

 from beak to the back of the head, and long, soft 

 plumes fall from the upper wing- and tail-coverts. 



During the mating season, the birds gather in small 

 companies and the males go through With a weird 

 kind of dance, in which they droop their wings, wave 

 their crests from side to side, and hop along in a 

 peculiar manner. See Plate 19, Fig. 112. 



Closely related to the Cock-of-the-Rock are the 

 Bell-birds, also of South America, of which four 

 species are known. The Naked-throated Bell-bird,
