PASSERES TYRANNID^E. 123 



168. (465.) EMPIDONAX VIRESCENS (Vieill.). 133. 



Green-crested Flycatcher. 



Synonyms: Empidonax acadicus, Tyrannus acadicus, Platyr- 



hinchos virescens. 



Acadian Flycatcher, Small Green-crested Flycatcher. 

 Kirtlan.d,.0hio Geol. Surv., 1838, 163. 



Apparently more pairs of this woods haunting flycatcher 

 nest in the northen half of the state than in the southern 

 half. It is fairly common everywhere, but may almost be 

 called abundant in the heavier woods in the north. Its 

 small size and weak voice cause it to be overlooked by many 

 who should know it. 



In its northward migration it reaches the lake shore about 

 the first of May, and does not return south before the second 

 week in September. 



169. (466.) EMPIDONAX TRAILLII (Aud.). 134. 



Traill Flycatcher. 



Synonyms: Empidonax pusillus traillii, Tyrannus traillii, Mus- 



cicapa traillii. 

 Little Flycatcher. 

 Read, Fam. Visitor, III, 1853, 359. 



This is another little known species, probably rather be- 

 cause it is so difficult to distinguish between the small fly- 

 catchers unless one knows the song, than because the bird 

 is rare. As a migrant it seems to be fairly common in most 

 counties, but only a few remain to breed in the southern 

 tier of counties. I found it breeding in considerable num- 

 bers at Licking reservoir and at Lewiston reservoir. It 

 prefers a willow or alder fringed lake or marsh for its sum- 

 mer home. A short distance from such places it may not 

 be found at all. 



This is one of the last of the migratory birds to appear ; 

 sometimes not reaching northern Ohio before the middle of 

 May, rarely before the 10th day. It is gone again by the 

 first of September.
