1922.] TRINIDAD BIRDS. 145 



19. Myiarchus Ujrannulus. Muller. Black-Billed cr Foolish Flycatcher 

 Myiobius nigriceps. Leotaud No. 122. 



One of these was shot at La Fortunee on July 11, 1918 m the 

 Lagoon on the edge of the cane cultivation. 



The stomach contained one froghopper (Tomaspis) and two 

 small green seeds with a red coating (?black sage). 



40. Tyrannus melancholicus. Licht. Grey-Headed Keskadee. 

 T. vertlcalis and T. vociferans. Leotaud No. 1 1 2. 



As noted above this bird replaces the Common Keskadee in the 

 open sugar growing districts of the Island, and is seldom seen m the 

 towns. It is distinguished from the Common Keskadee by the 

 greyish head (not black with a white eye streak) and by its quieter 

 habits. It is fond of sitting on the topmost branch of a low bush or 

 on the telegraph wires that run through the sugar estates. 



It nests in trees and bushes but the nest is a more normal cup 

 than that of the common keskadee without any attempt at a roof. 

 They have been found on the following occasions. 



(1 and 2) Two nests on March 26, 1918 at Craignish in a tree 

 bout fifteen feet from the ground, each close to the nest of the 

 mmon jack Spaniard (Polistes). 



(3) On June 27, 1918 at La Fortunee in a guava bush about 

 four feet from the ground, containing one young apparently less 

 than a week old. 



(4) On July 4, 1918 at La Fortunee in a wild pine (Bromdiad) in 

 a large Fiddlewood tree alongside a pond. The nest contained no 

 eggs and appeared to be in the process of construction. 



The food is chiefly insects as shown by the following dissections. 



(1) Shot at Caroni on September 28, 1917 among sugar cane 

 contained several dung beetles (Scarabeidae), two weevils, one 

 Chrysomelidae QCeratoma sp.) one moth and one butterfly. 



(2) Shot at Caroni on October 30, 1917 contained several 

 froghoppers {Tomaspis), one Scarabeid, one weevil and several 

 small beetles. 



On July 23, 1919 one was observed with field glasses to catch 

 .and eat a large dragon-fly.
