FAMILY XVIII. FLYCATCHERS (TYUNANIDiE) 



A large family (350 species) of American perching birds, 

 with a broad, depressed, notched bill, slightly hooked at tip;* 

 and almost no vocal powers. The flycatchers .can be 

 distinguished from most other birds by their peculiar 

 method of feeding. They perch on some outlying 

 twig or other support, watching for their prey ; when 

 a passing insect is seen, they dart out, seize it with a charac- 

 teristic dick of the bill, and in an instant return to their old 

 station, ready for another victim. Other birds (warblers, etc.) 

 catch insects on the wing, but have not this deliberate plan ; 

 they chase their i)rey. These solitary birds are to be found 

 wherever there are trees and bushes, but are most abundant 

 in the tropics. The sexual and seasonal differences are but 

 slight, but in nesting habits there are great variations.
