Common at Las Barrancas and from Ciudad Bolivar up to and 

 beyond Caicara. 



Adults have the eye seal brown ; bill black ; feet blackish slate. 

 The nesting season at Bolivar begins early in April. 



A male bird was flushed from a nest containing three fresh eggs 

 April 8th. The nest was situated in a large cavity of a fence post, 

 about 1.47 m. from the ground. The cavity was about 35.5 cm. 

 deep, open from above, and half way down one side the eggs were 

 easily seen at the bottom of the nest. The nesting material con- 

 sisted chiefly of cow hair with one or two bits of cloth and many 

 pieces of cast off snake skin scattered through the body of the nest 

 and about its upper edge. A few feathers formed a nest-lining, a 

 half-dozen bright green parrot scapulars adhering to a piece of skin 

 being most conspicuous.
