328 HORN-BILL. 



breast white ; tail long, cuneiform, the feathers black, ends of the 

 three outer ones white ; from behind each eye rises a white streak, 

 or line, surrounding the head as a wreath below the nape. 



The female is like the male, but wants the white wreath. 



Young birds are dusky black, where the adult is of a full colour, 

 and the white seems somewhat sullied. 



This species is found on the East of the South of Africa, from the 

 two Rivers called Great and Little Saumache (Klyn Brae and Groot 

 Brae), as far as the CatFre Country; frequents deep forests, and perches 

 vipon large trees, especially dead ones ; found in great flocks ; feeds 

 on insects and carrion ; will mix by hundreds with the Ravens and 

 Vultures, to feast on a dead beast, as M. Levaillant instanced once in 

 respect to an elephant he had killed. The female lays about four 

 white eggs, in a large hole of a tree ; she has two kinds of cry, the 

 one, cri cri cri qui qui qui, made during flight ; the other a graver 

 one, like the word Cou, when perched.
