FAM. PIPRIDA® 7 
white on their basal portion. Bill pale brown. Females uniform pale green, duller and lighter 
underneath. The frontal feathers are but slightly elongated. Wings 75-80, tail 65-70 mm. 
According to Natterer, this charming species frequents marshy places, keeping near to 
the ground, and has a loud, whistling song. Nothing is known of its nidification, but the eggs 
are described by Mr. J. A. Allen (Bull. Amer. Mus. Nat. Hist. 1893, Vol. 4, p. 154) as being 
of a buffy white colour and thickly covered with fine streaks and blotches of pale umber 
which become massed in a broad zone around the larger end, nearly concealing the ground 
colour.

Characters, In general form, the members of this genus come very close to some of the 
typical species of Pipra, e. g. P. aureola, but differ by their comparatively longer wings, 
shorter and broader bill and by the peculiar shape of the outer primaries in the male sex. Bill 
relatively small, rather broad at the base and abruptly attenuated towards the tip. Rictal 
bristles numerous, though rather soft. Nostrils open, though hidden by the supra-nasal feathers. 
In the wing, the third and fourth primaries form the tip, the second is somewhat shorter, the 
first equal to or a little less than the fifth. In the males, the three outer primaries are pointed, 
the shafts stiff and thickened, and the barbs reduced, especially near the tip of the outer web. 
The fourth and fifth primaries are also pointed, but to a lesser degree than the three outermost. 
The tail is short as in Pifra, but more rounded, the outermost rectrix being decidedly shorter 
than the inner ones. In one species (C. linearis) the middle pair of tail feathers is excessively 
elongated and lineiform. In two others (C. /anceolata and C. caudata) it is slightly lengthened 
and pointed. These peculiarities are common to both sexes of those species. Feet rather 
stronger than in Pifra, orange or red in life, 
Sexes dissimilar. The males are black and blue with the whole pileum or a large vertical 
crest bright yellow or red, while the females are clad in inconspicuous green colours. 
According to Euler (fourn. f. Ornith. 1867, p. 223) C. caudata builds its nest on the 
branches of low trees and lays two eggs which are of a buffy white ground colour and thickly 
(1) Buckley obtained a female near Simacu, Eastern Bolivia. Adult males are required to show if Bolivian birds are 
really identical with the Brazilian ones.
