174 TYRANNIDiE, FLYCATCIIEKS. GEN. 108, 109. 



summer, before the now worn features are renewed, the plumage is quite 

 brown, and diugy whitish ; very young birds have the wing-bars and edging 

 of quills tinged with rusty, the feathers of the upper parts skirted, and the 

 lower plumage tinged, with the same ; ))ut in any plumage the species may 

 be known from all the birds of the following genus, by these dimensions : 

 Length 6-GJ ; wing 3i-3J ; tail 22—3 ; tarsus, middle toe and claw together 

 hardly one inch, or evidently less; tarsus alone about ^, not longer than the 

 hill. N"()rth America, in woodhmd ; extremely abundant in most United 

 States localities. May — Sept. IJuscicajxt rapax Wils., ii, 81, pi. 13, f. 5;

 .t' CSJ Var. EiCHAEDSONii. Western Wood Peicee. Similar; darker, more fuscous olive 

 )-} above, the shading of the sides reaching almost uninterruptedly across the breast ; 



belly rather whitish than yellowish ; outer primary usually not obviouslj^ white- 

 edged ; bill below oftcner dusky than yellow, sometimes quite black. I fail to 

 appreciate auy reliable differences in size or shape. Note not exactly like that of 

 virens; nesting said to be different {Audubon, Alleii). Rocky Mountains to the

* 109. Genus EMPIDONAX Cabanis. 



*»* Species 5-G (rarely GJ-) long; wing 3 J or less; tail 2|- or less; whole foot 

 at least i as long as wing ; tarsus more or less obviously longer than middle toe 

 and claw, much longer than bill ; 2d, 3d and 4tb quills entering into point of wing, 

 1st shorter or not obviously' longer than uth ; tail not over J- an inch shorter than 

 wings; breast not buffy. (Compare 107, 108, 110.) As in allied genera, several 

 outer primaries are slightly euiarginate on the inner web, but this character is 

 obscure, and often inappreciable. Fig. 113cZ. 



, ') '' Small Green-crested or Acadian Flycatcher. Above, olive-green, clear, v 

 ;^ continuous 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, 3'ellowish-washed on 

 l)elly, Hanks, crissum and axiliars ; wings dusk}^, inner quills edged, and 

 coverts tipped, with tawny yellow ; all the quills whitish-edged internally ; 

 tail dusky, olive-glossed, unmarked; a yellowish ej'e-riug ; feet aud upper 

 niandible brown, under mandible pale. In midsummer, rather darker; in 

 /early fall, brighter and especially more yellowish below ; when very young, 

 the wing-markings more fulvous, the general plumage slightly bufly-suffused. 

 Largest; 5§-6i ; wing 2^-3 (rarely 3^) ; tail 2J-2f ; bill nearly or quite J, 

 about ^ wide at nostrils ; tarsus § ; middle toe and claw ^ ; point of wing 

 - rea(;hing nearly an inch be^'ond the secondaries ; 2d, 3d and 4lh quills nearly 

 C(pial and mucli (J inch or more) longer than 1st and .5th, which aljout equal 

 each other; 1st mucli, longer than Gth. Eastern United States, abundant, in 

 woodland; readily diagnoscible by the points of size and shape, without 

 regarding coloration. Muscicapa querula Wils., ii, 77, pi. 13, f. 3; J\I.
