 54. 



Range. N. and S. A. Breeds in Canadian and Transition zones from 

 cen. Alaska, s. Mackenzie, s. Keewatin, cen. Que., and Cape Breton Is. s. 

 in coniferous forests of w. U. S. to s. Calif., Ariz., and w. Tex., and also n.

Washington, casual T. V. Ossining, tolerably common T. V., May 20; 

 Aug. 15-Sept. 16. Cambridge, rare T. V., May 20- June 6; formerly not 

 uncommon S. R. ; one Sept. record. Glen Ellyn, not common T. V., May 13- 

 June 11; Aug. 11-Sept. 15. SE. Minn., common T. V., May 10-Sept. 9. 



Nest, of twigs and moss, in coniferous trees, about 25 feet up, near the 

 extremity of a limb. Eggs, 3-5, vinaceous-white, spotted, chiefly about the 

 larger end, with distinct and obscure rufous markings, '85 x '62. Date, 

 Wareham, Mass., June 8; Kentville, N. S., June 15. 



Both the Olive-side's habits and notes make it conspicuous. It 

 perches on the topmost limb of some high tree, where, even at a distance, 

 its stocky body and large head are evident, and calls its loud, strongly 

 accented "come right here, come right here," in a voice that commands 

 attention. 



461. Myiochanes virens (Linn.}. WOOD PEWEE. Ads. Upperparts 

 very dark, between olive and fuscous, with sometimes a tinge of dark olive- 

 green, wings and tail fuscous; wing-coverts tipped with whitish, forming 

 two more or less distinct wing-bars; underparts white or yellowish white, 

 washed with olive-gray on sides of throat and breast, and, to a less extent, 

 on center of breast; upper mandible black; lower mandible yellowish or 

 brownish, the tip frequently darker. Im. Similar, but yellower below, 

 wing-coverts edged with cream-buff. L., 6'53; W., 3'34; T., 2'62; B. from N., 

 42. 



Remarks. The Wood Pewee and the Olive-sided Flycatcher differ from 

 our other Flycatchers in having the wings decidedly longer than the tail, 

 and in their short tarsi. From the species of the genus Empidonax they may 

 be known by these characters and their darker, more fuscous coloration.

 Edward Island to s. Tex., and cen. Fla., w. to e. Nebr.; winters from Nicara-

 May 25; Ossining, N. Y., June 8; Cambridge, June 10; Mt. Carmel, Ills.,

Thoroughly to appreciate how well the Pewee's disposition is 

 suited to his haunts and notes, we have only to imagine him taking
