where it was not uncommon. The presence of this species in any 
locaHty seems to be governed largely, if not (.•ntirely, by the ripening 
of the fruits on which they feed. 
Fresh birds have the eye Indian purple, eye-lids burnt carmine; 
bill poppy-red with the distal one-fourth pearl white; feet heliotrope 
purple. 
Berlepsch and Hartert record a specimen collected by Klages at 
Suapure on the Caura River.

■Native name Turca. Common on the upper Orinoco as well as 
along the middle stretches of the river. This species feeds almost 
exclusively on fruits; it is chiefly arboreal, frequenting the less 
heavily wooded regions and borders of the dense forest, and is, except- 
ing during the nesting season, gregarious. 
Eye rose red; bill black; feet rose red, claws dusky. 
Nests of this species were found in Morichc palms and the 
tangled thickets that grow in and about marshy places, also in the 
scrub-oaks scattered over the savannas. The nest is a very slight 
platform of dead twigs located at from two to five metres from the 
ground. Only one egg is laid. An egg with incubation well ad- 
vanced, taken at Caicara, June 5th, is white, elliptical ovate in form 
and measures 39.3 x 26 mm.
