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,

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, strcngly 
accented “‘come right here, come right here,” in a voice that commands 
attention. 
461. Myiochanes virens (Linn.). Woop Prwsr. Ads.—Upperparts 
very dark, between olive and fuscous, with sometimes a tinge of dark olive-

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 Empidonaz 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-

Thoroughly to appreciate how well the Pewee’s disposition is 
suited to his haunts and notes, we have only to imagine him taking
