tially similar to that of the Wood Pewee, the structure 

 being saddled on a horizontal limb, or fixed in a fork, 

 often at a great height from the ground. The nest is a 

 shallow, saucer-like fabric of twigs, rootlets, weed-stalks, 

 bark-strips and other similar material, rather loosely put 

 together. The very handsome eggs are of a pure creamy 

 white, speckled with brown or reddish and lilaceous 

 shades ; they are four or three in number, measuring 

 about 0.85x0.65, and are laid from the last week in 

 May, as in Massachusetts, to middle of June in Maine.

CONTOPUS VIRENS {L.) Cab. 



Chars. With the form and proportions of the last species, but 

 much smaller. Length, 6.00-6.50 ; wing, 3.25-3.50 ; tail, 2.75- 

 3.00 ; tarsus, middle toe and claw, together, scarcely or not 

 l.oo; tarsus alone, about 0.50, thus no longer than the bill; no 

 evident white tuft on the flank; head sub-crested, with erectile 

 feathers. Olive-brown, rather darker on the head ; sides with a 

 paler shade of the same, reaching nearly or quite across the 

 breast ; the throat and belly whitish, more or less tinged with, 

 yellowish ; under tail-coverts the same, usually streaked with 

 dusky; tail and wings blackish, the secondaries and coverts 

 edged and tipped with whitish ; feet and upper mandible black ; 

 under mandible usually yellow, sometimes dusky. 



In numbers according to latitudinal distribution the 

 well-known Wood Pewee presents the reverse state of the 

 case just outlined for the Olive-sided Flycatcher, being 

 most abundant in southern New England, and gradually 

 becoming less numerous as we proceed northward. 

 Nevertheless, it is one of New England's very com-
