AcCIPITER RUFIVENTRIS. 
A. supra brunneus; infra subfulvus; remiges brunnee, 
pogoniis internis nigro fasciatis, cauda fuscis quinque nigris et 
quatuor ceruleo-griseis notata. 
Falco rufiventris, Latham’s History of Birds, vol. 1, p. 284. 
—Daud. Orn. tom. 2, p. 86.—Hpervier bleuatre, Voy. d’ Azara, 
3, No. 26. 
Male,—Bill, with the exception of a small yellow spot near 
base of upper mandible, and another opposite it on the lower, 
black; head, hinder part of neck, back, upper tail coverts, 
and shoulders brown, with a tinge of deep slate color, which 
is particularly strong soon after moulting; sides of neck, 
chin, throat, breast, anterior part of belly, and thighs light 
rufous, the three first the palest ; hinder part of belly dirty 
white, banded transversely with rufous; under tail coverts 
white. Primary wing feathers dirty brown, the inner vanes 
banded with black, and towards quill marked on their inner 
edges between the bands by pure white ; secondaries brown, 
with the inner vanes banded with dusky black, and varied 
with white in the same situations as the primaries. Tail 
slightly rounded, and marked by five broad transverse bands 
of dusky black, and four of a dusky or pure bluish gray, tips 
of all the feathers white; legs and toes yellow; claws black. 
Length from bill to base of tail five inches and a half; length 
of tail four and a half. 
Female.—Length from bill to base of tail seven inches ; 
length of tai! seven inches; colors more dull above, and 
rather deeper beneath. 
Young.—Color above brown, without the dark slate tint of 
the mature bird, and varied particularly about the shoulders, 
head, neck, &c. by each feather being narrowly edged with 
rufous ; legs pale yellow; claws dark horn colored. 
This species occurs along the South-east coast and to some 
very considerable distance inland, at least I have seen several 
specimens from the neighbourhood of Baviaans River, and 
from the country towards the southern branches of the Orange 
River; I have also seen examples of the same bird which 
were killed near Constantia, and between that and Cape Town. 
Obs.—This appears to agree with the description of the 
Falco rufiventris of Shaw ; and, though he describes his bird 
as being a native of Cayenne, it might possibly have been 
obtained from the Cape, or the species may be an inhabitant 
of both countries.
