118 CLASS AVES. 



become well accustomed to the climate, the female brings up 

 her little ones extremely Avell ; but it often occurs that the 

 greatest quantity of the eggs are clear, Avhich proceeds from 

 not giving to these birds sufficient liberty. By fastening 

 their wings, and leaving them a large space, shaded on one 

 side, the broods will thrive extremely well. The eggs are 

 white, and of the size of those of the turkey. The hen 

 turkey may be employed both to hatch these eggs, and 

 educate the young, as the time of incubation is the same 

 with both birds. The little ones are covered with a brown 

 down, and the globe which should surmount the head is not 

 apparent at this early age. After the first moulting it 

 shows itself by a small tubercle, which increases in propor- 

 tion as the bird advances in age. The male and female are 

 alike provided with this appendage, but it is somewhat smaller 

 in the latter. 



The total length of the Craw Pauxi (male,) is two feet 

 ten inches ; in size and bulk, it altogether equals the domestic 

 turkey. The bill is short and greatly curved, and its length 

 from the feathered part where the nostrils are situated, is 

 about an inch. The globe which surmounts it adheres to the 

 base of the upper mandible. This globe or stone, from which 

 the bird is named in French, is, in adult individuals, of an 

 osseous substance, and covered with grooves, which resemble 

 ramifications. In the interior, which is empty, are found 

 small cells, Avhich the bird has apparently the faculty of fill- 

 ing with air, by means of an aperture which corresponds 

 with the interior of the bill. In the young, this stone has a 

 rovmded form, but in old males it is like a pear reversed, and 

 is two inches and a half in height. 



Besides the very powerful cry of po-hic, which this bird 

 utters, it also sends forth the dull humming sound which 

 we have noticed when discoursing of the genus. The voices 

 both of male and female are alike, exceedingly sonorous, and 

 heard at a great distance. In the male, the trachea, having
