250 " ■ FLYCATCHERS. 



rapid twitching of the tail. A more peculiar note is a louder pee-e- 

 yuk. The bird seems to articulate this note with difficulty, with bill 

 pointed upward and wings trembling like a fledgling begging for food. 

 Sometimes you may hear only the first call, sometimes only the 

 second, while on other occasions the two may be uttered alternately. 

 A rarer note may be heard when the bird makes a short, fluttering 

 flight. It resembles the soft murmuring of whistling wings.

 Upper parts between olive-green and olive or olive-brown ; wings and tail

EemarTcs. — This is the brownest of our small Flycatchers. The upper 

 parts have an evident tinge of brown or olive-brown, a color entirely want- 

 ing in the Acadian and Yellow-bellied Flycatchers. In this respect it resem- 

 bles the much smaller Least Flycatcher. 



Jiamje.—'^orth America; breeds from i\rizona, Missouri, southern Illinois, 

 northern New England, and casually Connecticut, north to New Brunswick

While the Yellow-bellied Flycatcher is distinctively a bird ( t the 

 deep woods, this more abundant Flycatcher in its summer home re- 

 sorts to the alder patches of the open country and is seldom found far 

 from their protecting shade. It flits restlessly about, keeping well out 

 of sight below the waving tops of the bushes, and its presence is be- 

 trayed only by a single pep of alarm that in no way resembles the 

 mournful wail of the species just mentioned. It, too. is silent when 

 migrating, and on its breeding grounds sings but little, so that if it 

 did not take pains to call out to every one who passes it would not be 

 noticed among the rustling alders. The song most resembles that of 

 the Acadian Flycatcher, an ee-zee-e-up, with stress on the rasping 

 zee, the latter part more musical. The performer jerks out the notes 

 rapidly, doubling himself up and fairly vibrating with the explosive 

 effort. J- DwiGHT, Je.
