PASSERES—TYRANNIDZ. 123 
168.. (465.) EMPpIDONAX VIRESCENS (Vieill.). 133. 
Green-crested Flycatcher. 
Synonyms: Empidonax acadicus, Tyrannus acadicus, Platyr- 
hinchos virescens. 
Acadian Flycatcher, Small Green-crested Flycatcher. 
Kirtland, Ohio 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 inthe 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.) EMPprmpONAX 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.
