The writer observed this species only on the upper river above the 
falls of Maipures, where it was common. Beebe on a recent expedition 
secured a specimen at Guanoco in the Orinoco deltas However, the 
species has been previously recorded from the same point by Hellmayr.^ 
I was informed by the natives that this species builds a hanging 
nest, similar to those of Cacicus, but was unable to verify the statement.
