YELLOW-OLIVE FLYCATCHER 



"Found in wild banana thickets and in the 

 forest." (Jewel.) A rather stoutly built fly- 

 catcher of medium size with fairly long tail, 

 generally olive coloration with a yellowish cast, 

 and very broad bill. Seen sitting on low 

 branches in thick jungle on Barro Colorado Is- 

 land. It was tame and unsuspicious and occa- 

 sionaly uttered a two-syllabled call. 



Genus Rhynchocyclus 



Small flycatchers having considerable re- 

 semblance to those of the genus Empidonax 

 in size, colors and habits, but distinguished 

 by the proportionately larger head and 

 stouter, broader bill, which is noticeably 

 curved downward.
