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 delta 1 . However, the 

 species has been previously recorded from the same point by Hellmayr. 2 



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.

Common in the open country along the lower and middle stretches 

 of the river. At Ciudad Bolivar, in April, it was associating in flocks 

 with Gymnomystax mexicanus and Holoquiscalus lugubris. 



Three breeding females, as indicated by the active condition of the 

 ovaries, collected at Caicara, one May i5th, another June I2th and the 

 third, June I3th, are almost exactly uniform in size. The measurements 

 of the one taken May 15, 1907 (No. 4861, Brooklyn Institute Museum), 

 being wing 102 mm., tail 78 mm., exposed culmen 17 mm., depth 

 of bill at nostrils 8 mm. Above, the. three are also almost of identically 

 the same shade of dusky brownish, the individual feathers being 

 brownish black bordered with dusky greyish; below, the three present 

 a quite distinct appearance. No. 4861 (Bklyn. Inst. Mus.), is greyish 

 hair brown, faintly washed on the breast and sides with olive yellowish 



In the (British Mus.) Catalogue of Birds XI. 1886. p. 389. Trinidad is included in the list of localities. 

 But it is not in Chapman's list nor in that of Hellmayr, Novit. Zool. XIII. 1906. pp. 1-60, not even in his 

 hypothetical list.
