B. ferrugineus ; gqutture, pectore et tectricibus inferioribus 
caude subalbidis ; abdomine nigro notatis; remigibus primori- 
bus nigris, cauda subtus ferruginea infra grisea indistincte 
fasciata ; rostro et tarsis flavis ; oculis rubris. 
Male.—Bill and cere yellow; eyes red; head, neck, back, 
and belly ferruginous red; the latter with dashes of black ; 
throat, breast, and under tail coverts grayish white. Pri- 
mary quill feathers black. Tail ferruginous red above, gray- 
ish white, with indistinct transverse bands, beneath ; legs and 
toes yellow; claws black. Size considerably below that of 
the Buteo Jackals, or most common South African buzzard. 
Female.—Size rather exceeding that of the male, and the 
ferruginous tint is less deep and brilliant. 
This species I have never met with, and am therefore 
forced to have recourse to the works of Le Vaillant. He 
states that it inhabits the more retired spots of South Africa ; 
that it feeds upon rats, moles, mice, and even insects ; and that 
its ery resembles much that of the common Kuropean buzzard. 
It places its nest in bushes ; constructs it externally of dry 
twigs, internally of wool, hair, and feathers; and lays from 
three to four eggs.
