FLYCATCHERS 41 



Known chiefly as a not common migrant who visits 

 our woods on his journey to and from his northern home. 

 He is a silent traveler and gives no clue to his identity 

 by calling or singing, but his underparts are so much 

 yellower than those of any other of our small Flycatchers 

 that they make a definite field character. Nests in 

 coniferous forests on the ground, laying 4 white, lightly 

 spotted eggs in June. 



ACADIAN FLYCATCHER 

 Empidonax virescens. Case 8, Fig. 60 



Throat white, upperparts bright, light olive-green, without 

 tinge of brown as in the Alder Flycatcher. 



Range. Eastern North America; rather southern, nesting 

 from Florida north to Connecticut and Michigan; winters in the 

 tropics. 



Washington, common S. R„ May i-Sept. 15. Ossining, com- 

 mon S. R., May 10-Aug. 27. N. Ohio, common S. R., May 4- 

 Sept. 15. Glen Ellyn, not common S. R., May 6-Aug. 27, and 

 probably later. 



On the low-sweeping limb of a beech over a stream is an 

 ideal site for the frail nest of the Acadian. The bird is 

 never found far from it and its low-ranging habits permit 

 us to see its characteristic markings and hear its peculiar 

 sudden, explosive little pee-e-ytik and more commonly 

 uttered spee or peet. 



The creamy white, brown-spotted eggs are laid the latter 

 part of May. 



ALDER FLYCATCHER 

 Empidonax trailli alnorum. Case 8, Fig. 62 



Larger than the Least Flycatcher, but resembling it in having 

 the back olive-brown instead of olive-green as in the Acadian 

 and Yellow-bellied Flycatchers. L. 6. 



Range. Eastern North America; nests from northern New 

 Jersey (locally) and mountains of West Virginia to Canada; 

 Winters in the tropics.
