22, 1922 (Bangs and Barbour, Bull. Mus. Comp. Zool, vol. 65, 

 1922, p. 206). 



G .V. N. Powell recorded one feeding a nearly grown fledgling on 

 Cerro Campana, November 11, 1966. 



In the stomachs of two taken by Goldman near Cana I found 

 fragments of spiders, with remains of their eggs, and a variety of 

 small insects, including a cicada, a cricket, another orthopteran, small 

 bees, a caterpillar skin, pentatomids, and beetles — a chrysomelid, 

 two carabids, a cerambycid, and several weevils.
