FLYCATCHERS. 



the young by regurgitation — a frightful-looking act— the food consist- 

 ing largely of minute insects. The young remain in the nest for some 

 three weeks, and on leaving it are at once at home on the wing.

From the systematist's standpoint Flycatchers are songless Perch- 

 ing Birds. It does not follow that they are voiceless, or even truly 

 songless, but that, having the voice-organ or syrinx less highly devel- 

 oped than other Passeres, they are possessed of comparatively limited 

 vocal powers. This family is pe«?uliar to America. The Old- World 

 Flycatchers belong to the family MiiscicapidiB and are true OsrineH. 

 Some three hundred and fifty species are known. They are most abun- 

 dant in the tropics, where their services as insect-catchers are in great- 

 est demand. About thirty-five species reach the United States. 



Flycatchers are found wherever there are trees. As a rule they are 

 of sedentary and solitary disposition. Their manner of feeding is 

 characteristic. From a favorable perch, hawklike, they await passing 

 insects, and with an aim that rarely misses launch forth into the air ; 

 there is a sharp, suggestive rh'ek of the broad bill, and, completing 

 their aerial circle, they return to their perch and are again en yarde.
