In the heavily wooded regions al)o\-e the falls of the Orinoco this 
species replaces the abundant P. ftavit^es acutieauda of the middle and 
lower stretches of the river. Except during the nesting season it 
associates in small flocks or family parties which frequently join the 
mixed companies of birds that are so characteristic of tropical forests. 
This species was also collected on the Caura River at Suapure 
(Klages) and Nicare and La Pricion (Andre).

Conmion at Ciudad Bolivar and Caicara. 
All specimens procured indicated that the species was brooding 
in May and Tune, but I did not succeed in finding either nest or eggs.
