COCK OF THE ROCK —n7ipicnta aynhifia. 



the head. The tips of the crest-featliers are tinged with browni and yellow. Upon the 

 wing-coverts and the upper taO-coverts, the feathers are modified into flowing plumes, 

 which droop in a very graceful manner over the firmer feathers of the tail and sides. In 

 size the Cock of the Eock aboiit equals a common pigeon. 



The female bird is not nearly so beautiful as her mate, being of a yellowish-brown 

 colour, and having only a small and inconspicuous crest. 



Another species of Monakin which belongs to the same genus is the PERrviAN Cock 

 OF THE Eock {RuiyicoJa Peruvidnd), a bird which is possessed of considerable beauty, 

 though it is not quite so splendid as the previous species. Like that bird, its plumage is 

 of a bright orange colour, but its crest wants the curious fan-like form which is so 

 conspicuous in the Cock of the Eock, and the quill and tail-feathers are jetty black, and 

 the wing-coverts are ashen grey. Moreover, the feathers of the wing-coverts and upper 

 tail-coverts are not so loose and flowing, and its tail is longer in proportion. 



There is one species of Manakin which does not, so far as is known, inhabit America, 

 but is found in Singapore and the interior of Sumatra. This is the Green Calyptomena 

 ( Calyptomena viridis), a very beautiful, though not very large bird. Like the Cock of the 

 Eock, it is extremely shy and solitaiy in its habits, but instead of retiring into the deep 

 recesses of rocky ground, it shrouds itself among the heavy verdm^e of the forest trees, 

 where its bright green feathers harmonize so well with the foliage, that it is hardly percep- 

 tible even to a practised eye. The food of this bird seems to" be entirely of a vegetahle 

 character.
