MYIODYNASTES MACULATUS DIFFICILIS Zimmer: Streaked Flycatcher, 
Piquigordo Rayado 
Myiodynastes maculatus difficilis Zimmer, Amer. Mus. Nov., No. 963, Nov. 18, 
1937, p. 9. (Bebedero, Costa Rica.) 
The streaked flycatcher was found on few occasions, usually in 
the trees along the forest trails, or occasionally in the border of 
mangrove swamps at the river mouths. As they called seldom at this 
season they may have been more common than the five specimens 
collected may indicate, since it was not easy to see them in the leafy 
branches amid which they usually rested.
