Containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland and Lower California, with which are incorporated General ornithology: an outline of the structure and classification of birds; and Field ornithology, a manual of collecting, preparing, and preserving birds. Birds; Birds. 444 SYSTEMATIC SYNOPSIS. —PICABI^. overhanging tip; commissure gently decurved; gonys about straight. Head a little crested, as in Empidonax, Contopus, etc. Wings of moderate length, much rounded; 2d to 5th prima- ries subequal and longest, 6th shorter, 1st about equal to 7th. Tail a little shorter than wings, even or scarcely rounded. Tarsus long, exceeding the middle toe and claw; lateral toes sub- equal, their claws about reaching base of middle claw; hind claw shorter than its digit. Of diminutive size, and duU plain colors, as in the small olivaceous liycatchers generally; but for the bill, the species might be mistaken fur an Empidonax. 393. O. imber'be. (Lat. imberbis, beardless ; in, not, and barba, a beard.) Texas Beardless Flycatcher. Adult ^ 9: Above, dull olive-gray, a little darker (browner) on the length- • ened erectile feathers of the crown, a little brighter (greener) on the rump and upper tail-coverts. Below, pale duU gray, sometimes almost grayish-white anteriorly, clearing on the belly and under taQ-coverts to pale yellowish. Wings and tail fuscous, with pale gray or whitish edgings of the middle and greater coverts and most of the quiUs of the wings, as in an Empidonax. Bin dark brovni above, pale below. Worn specimens are quite brownish above, and whitish below, with little edging of the wings and tail. Young and fresh fall specimens are more clearly olivaceous above and yellowish below, shaded with gray across the breast; the young with the wing-bars tinged with buff or tawny — all quite as usual in Empidonax.
