SONOLESS BIRDS OF ORCHARD AND WOODLAND. 231 



it also picks up many which are stirring onl}^ very early in 

 the morning or at evening. The bird watches for cater- 

 pillars, and when it sees one stir, flies from its perch and 

 snaps up the luckless creature. This bird, in common Avith 

 other Flycatchers, picks up many caterpillars 

 that, to escape Warblers and other enemies,
