384. E. aca/dicus. (Lat. of Acadia.) Small Geeen-crbsted or Acadian Flycatcher. 

 Above, o^Ye-green, clear, light, oontinuous and uniform (though the crown may show rather 

 darker, owing to dusky centres of the slightly lengthened, erectile feathers) ; below, whitish, 

 olive-shaded on sides and nearly across breast, yellowish-washed on belly, flanks, crissum and 

 axillars; wings dusky, inner quills edged, and coverts tipped, with tawny yellow; all the 

 quills whitish-edged internally ; tail dusky, olive-glossed, unmarked ; a tawny eye-ring ; feet 

 and upper mandible brown, under mandible pale. In midsummer, rather darker ; in early fall 

 brighter and especially more yellowish below ; in the young, the wing-markings more fulvous, 

 the general plumage slightly buflfy-suffused ; when very young, said to be mottled transversely 

 with pale ochraceous. Largest: 5.75-6.25 — rather over than under 6.00 f extent rather over 

 than under 9.50 ; wing 2.75-3.00 (even 3.12) ; tail 2.50-2.75 ; bill nearly or quite 0.50, about 

 0.25 wide at nostrils, broad and flat, like a pewee's ; tarsus 0.66 ; middle toe and claw 0.50 ; 

 point of wing reaching nearly an inch beyond the secondaries ; 2d, 3d, and 4th quills nearly equal 

 and miiich (^ inch or more) longer than 1st and 5th, which about equal each other ; 1st much 

 longer than 6th. The 9 near the lesser of all the dimensions given. Eastern U. S., southerly, 

 scarcely known in New England; abundant in the Middle and Western States in woodland ; 

 readily recognized by the points of size and shape, without regarding coloration. Nest in trees, 

 in horizontal fork of a slender bough; thin and open-worked, shallow, flat, saucer-shaped ; eggs 

 2-4, 0.78 X 0.56, creamy-white, boldly spotted, resembling a wood pewee's. {Muscicapa suh-

385. E. trailli. (To T. S. Traill, of Edinburgh.) Traill's Flycatcher. Above, olive- 

 hrown, lighter and duller brownish posteriorly, darker on head, owing to obviously dusky 

 centres of the coronal feathers ; below, nearly as in acadicus, but darker, the olive-gray shading 

 quite across the breast ; wing-markings grayish-white with slight yellowish or tawny shade ; 

 under mandible pale; upper mandible and feet black. Averaging smaller than acadicus; 

 length 5.50-6.00; extent under 9.50, usually 8.75-9.00; wing 2. 66-2.75, more rounded than 

 in acadicus, its tip only reaching about f of an inch beyond the secondaries, formed by 2d, 3d 

 and 4th quills, as before, but 5th not so much shorter (hardly or not \ of an inch) , the 1st ranging 

 between 5th and 6th ; tail 2.50; tarsus 0.66, as before, but middle toe and claw 0.60, the feet 

 thus diflferently proportioned, owing to length of toes ; bill not so broad and flat as in acadicus. 

 Eastern N. Am. to the Plains, common ; an entirely different bird from acadicus, but diificult 

 if not impossible to distinguish from the following variety ; almost the same in color as minimus, 

 but larger, and otherwise perfectly distinct. A common breeder from New England and Canada
