Agreeing with specimens from Cayenne, Venezuela, and Trinidad. 
Mr. Hoffmanns reports that this bird lays a single egg on the ground amidst 
dry leaves and grasses. One egg, taken at Calama, October 14, 1907, is pinkish 
buff, indistinctly spotted with pale reddish brown and underlying lavender-grey. 
Another egg is much brighter pink, with the reddish spots more numerous, but 
with very little lavender-grey, They measure 29°75 x 20-50 and 30 x 21°50 mm.

Compared with several skins from Bahia and Ypanema (S. Panlo) this bird is 
of a brighter rafous brown, but the markings are the same, Topotypical Peruvian 
Specimens are not available for examination. 
C. rosenbergi Hart.,* from Western Colombia and N.W. Ecuador, is very 
nearly allied to C. ocellatus, and, like it, has no white cross-bar on the remiges. 
However, the general colour is blackish, the white apical margin to the rectrices 
is much narrower, there are no cinnamomeous marginal spots on the outer web of 
the primaries, while, on the other hand, each of the innermost greater wing- 
coverts has a large, rounded white apical spot.
