Habits. Schomburgk states (Reis. Guian. iii. p. 667) that he met 

 with this bird in small flocks, usually in thin woods and in the fields 

 cultivated by the Indians. He did not observe it on the open 

 coast, but it was somewhat common near the Pomeroon, Barima, 

 Barama, and Aruka rivers. He always found it on medium 

 sized trees, and never once saw it on the ground. Its nidification 

 was unknown to him. The " Warraus" called it Quahorum and 

 the " Arawaaks " Ihibiru.
