TYRANNID.'E—TYRANNINJE: TYRANT FLYCATCHERS. 525 



CATCHER. Adult $ 9 • Somewhat similar to borealis ; colors more uniform and more clearlj' 

 olive ; below, dull brownish-olive, lighter ou throat, fading insensibly on belly into dingy yel- 

 lowish-white ; lacking the peculiar streaky appearance of borealis. Cottony tufts on Hanks 

 less conspicuous but tibservable. Bill longer and comparatively narrower than in borealis ; 

 black above, yellow below; feet black. Wing-formula entirely different; 2d, 3d, and 4th 

 quills nearly equal and longest, 1st abruptly 0.50 shorter, about as long as 5th, or between 5th 

 and 6th. Feet small, weak, and properly " contopine," but tarsus if anything longer, not 

 shorter, than middle toe and claw, about equalling bill (reverse proportion of bill, tarsus, and 

 toe obtains in borealis). Length of ^ about 8.00; extent 13.00; wing 4.00-4.30; tail 3.50- 

 3.80 ; bill and tarsus, each, about 0.G7 ; middle toe and claw 0.60. 9 rather less. Young: 

 Lower mandible and mouth orange-yellow; feathers of wings and tail and their coverts skirted 

 with rusty, and a shade of the same on under parts generally. Midsummer adults wear 

 browner, like the common Wood Pewee ; in fact, the whole coloration of the species is the 

 counterpart of a Wood Pewee's. Northern Mexico, where resident in mountains and on high- 

 lands, N. to New Mexico and Arizona, casually to Colorado ; common in mountainous pine- 

 ries, where it nests in June, both on coniferous and deciduous trees, withdrawing southward in 

 September. I took the first specimen known within our limits at Fort Whipple, Ariz., Aug. 

 20, 1864. Nest like that of the common Wood Pewee, but larger, 4.00-5.00 in diam. outside 

 by 2.00 deep, cupped 2.00-3.00 by about 1.00, composed mostly of grasses, with some leaves, 

 catkins, mosses, lichens, cobwebs, etc Eggs 3, about 0.83 X 0.63, creamy buff, spotted with 

 lighter and darker reddish-brt)wns and lilac, the markings sparse and tending to wreathe about 

 large end. C. jfjer^i««.c of all former eds. of the Key. C. p. imllidicentris Chapm. Auk,

C. vi'rens. (Lat. virens, virent, greenish. Fig. 352.) Wood Pewee. Adult $ 9 : Oli- 

 vaceous-brown, rather darker on head ; below, with sides washed with a paler shade of the 

 same, reaching nearly or quite across breast; throat and belly whitish, mure or less tinged 

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

 with dusky; tail and wings blackish, former unmarked, inner 

 wing-quills edged, and greater and middle coverts tipped, with 

 •whitish ; feet and upper mandible black ; under mandible usu- 

 ally yellow, sometimes dusky; iris brown. Spring specimens 

 ])urer olivaceous; early fall birds brighter yellow below ; in sum- 

 mer, before the worn feathers are renewed, the plumage is quite 

 brown and dingy whitish. Very young birds have the wing- 

 bars and edging of quills tinged with rusty ; feathers of upper 

 parts skirted, and lower plumage tinged, with the same; but in

 Eastern N. Am., in woodland; extremely abundant in most U. S. localities, May-Sept., enter- 

 ing U. S. from the South usually in March, reaching its limit of dispersion in adjoining Cana- 

 <lian localities from New lirunswick to Manitoba by the end of April or early in May. Possibly 

 winters along the southern border, but extends at that season through E. Mexico and Central 

 Am. to equatorial regions. West only to the high central plains, as of the Dakotas, Nebraska, 

 Indian Territory, and Texas. In the breeding season the peculiarly plaintive, drawling note
