edge would suggest. It will probably be found commonly distributed in places that 

 are particularly suited to it. 



Food. Nothing recorded. 



Courtship and Nesting. No courtship, and no tendency to mate or nest have 

 been observed in captive birds in the New York Zoological Gardens. 



Status. The apparent recent extension of its range to the north (British Guiana) 

 is of interest. 



Food Value. No information. 



Behavior in Captivity. The species was first received at the London Zoological 

 Gardens in 1876. It has never bred, but was still living in 1883 (Sclater, 1883). It has 

 also been kept in Berlin, and in the Buenos Aires Gardens. 



The New York Zoological Gardens received two males and one female, all im- 

 mature when taken in November, 1918, near Barcelona, Venezuela (Crandall, Auk, 

 vol. 36, p. 419, 1919). In June, 1919, one of the males killed the other one. The re- 

 maining male which I observed in January, 1920, had the reputation of being one of 

 the most pugnacious birds in the Gardens, and was kept in a pen by hhnself all 

 winter.
