in evidence, and more peculiar that the little gray 

 bird that utters it from the branches above. Watch 

 and ycu may see him dart out after a fly. How- 

 ever, the latter habit is common among flycatchers. 



466a. Alder Flycatcher — Empidonax trail li 

 a! no rum. 



Length 6% inches. 



Two pale, but not white, wing-bars; underparts 

 whitish, washed dusky grayish on breast and sides, 

 pale yellowish on belly; throat white; upperparts 

 olive. 



This little flycatcher is best identified by his 

 haunts and notes. Look for him, or rather listen 

 for him, in wet alder thickets. He will flit ahead 

 of you, keeping mostly hidden, but frequently giv- 

 ing his call-note, a single peep, or ocasionally what 

 answers for his song, a simple ee-zee-ep, impos- 

 sible to mistake for the notes of the Pewee or the 

 Chebec, which birds resemble the Alder Fly- 

 catcher in general appearance. 



467. Least Flycatcher — Empidonax minimus. 



Length 5-}$ inches. 



Without distinct wing-bars; upperparts olive; 

 wings and tail blackish; underparts whitish, 

 washed with dusky grayish on breast and sides, 

 white or yellowish white on belly. 



The haunts and in general the habits of the 

 Chebec, as this bird is called from its common note, 

 are similar to the Wood Pewee's ; but the present 

 species is more fond of the orchard, frequently 

 building in an aople tree. From the Wood Pewee 

 he may be known by absence of distinct white wing- 

 bars, smaller size, and his call chee-beck which he 

 is apt to repeat insistently even in the hottest hours 

 of the day.
