330 • HORN-BILL. 



scapulars, and upper tail coverts dirty grey ; wing coverts blackish, 

 the middle of each feather dirty white ; prime quills blackish, secon- 

 daries grey ; tail near seven inches long, rather cuneiform, the two 

 middle feathers dirty grey, the rest blackish, with the ends white ; 

 legs red-brown ; claws black. 



The young bird has the bill orange, without indented edges, and 

 the white in the plumage dirty. — The one described by Brisson, is 

 the young bird.— Such is the description of the two, which Linnaeus 

 thought to be male and female ; but BufFon supposes them to differ 

 only from the age, the last described being the adult bird. 



This and the Black-billed inhabit Senegal and other parts of 

 Africa, and are both called Tock ; are tame while young, suffering 

 themselves to be taken with the hand, but when mature are very shy; 

 the young soon become familiar, yet are so stupid as not to feed 

 themselves, requiring the food to be put into their mouths. In their 

 wild state they subsist on fruits, but when domesticated eat bread* 

 or almost any thing that is offered to them. 



The black-billed is, no doubt, the bird described by M. Forskal, 

 who says, the bill is twice as long as the head, and bends downwards, 

 with a spot of white at the base of the upper mandible ; on the lower 

 three or four whitish, curved ridges ; that the head and neck 

 are grey-brown ; belly white ; and the rest of the bird grey ; spotted 

 with white ; quills tipped with white, the prime ones cinereous, 

 secondaries black ; tail feathers ten in number, as long as the body, 

 even at the end, black tipped with white, except the two middle 5 

 which are wholly brown, &c. 



M. Forskal adds, that it inhabits Arabia, and is called there 

 Tulloek and Dymludi. Feeds on serpents.
