BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 385 
The so-called Orinoco ‘‘goose’”’ is found throughout the areas 
involved in the present report. According to Phillips (Natural 
history of the ducks, vol. 1, 1922, p. 201) it is the commonest duck on 
the Orinoco; it inhabits wet and densely wooded tropical lowlands.

March 15, 1931. 
The yellow-headed vulture occurs from northeastern Venezuela 
and the Guianas south to northern Argentina and Uruguay. Because 
of the unpleasantness in handling, it (like many of its congeners) 
is all too rare in collections and has been studied but little. Not 
enough specimens are available to attempt a study of its possible 
variations.

Falco uncinatus “Tlliger’” Temmincx, Nouveau recueil de planches coloriées

north of Brazil and all of Guiana’). 
SPECIMEN COLLECTED 
1 ad.—, Venezuela, Ciudad Bolivar, June 9, 1931. 
The single example obtained of this rather uncommon hawk is 
preserved in alcohol. It is in the gray-barred type of plumage. 
ACCIPITER PECTORALIS (Bonaparte): Red-collared Goshawk 
Falco pectoralis BONAPARTE, Rev. et Mag. Zool., 1850, p. 490 (Brazil), 
SPECIMEN COLLECTED 
1 ad—, Venezuela, Cerro Yapacana, Upper Orinoco, April 23, 1931. 
By plumage and measurements (wing 263, tail 200 mm.) this speci- 
men is apparently an adult male. As has been pointed out by earlier 
writers this hawk is very similar to, but much smaller than, Spizaetus 
ornatus in appearance. It is a very rare bird and still is known from 
only a few widely scattered localities and specimens. 
This appears to be the second known Venezuelan specimen, the 
other being a female from Mount Auydn-tepuf, recorded by Gilliard 
(Bull. Amer. Mus. Nat. Hist., vol. 77, 1941, p. 457).
