The lone example of this widely ranging bird obtained by the 
expedition was in breeding condition when shot. There are no 
geographic variations of any account, according to Zimmer (Amer. 
Mus. Nov., No. 785, 1935, p. 6).

This fine series bears out the distinctions made for the race by 
Zimmer (cit. supra). This is another of the many birds that range 
from the Amazonian (Rio Negro) Basin into that of the Upper Orinoco 
without change. 
‘The Venezuelan examples are somewhat more ashy, less buffy on 
the breast and abdomen, than are the Brazilian specimens. The 
former average slightly less rufescent above as well.
