344 FLYCATCHERS. 



catchers are not difficult to recognize in 

 spring when they are giving their notes, in 

 autumn when they are silent it is extremely 

 hard to identify them, especially as all are 

 then in more obscure dress, when the char- 

 acteristic markings are quite alike. It is 

 well also to remember that all migrate al- 

 most as soon as the young are able to do so. 

 and consequently none of the species would 

 be apt to have time to wander north of 

 their usual habits in autumn.
