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 suhequal 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 dull plain colors, as in the small olivaceous flycatchers generally ; but for 

 the bill, the species might be mistaken for an Empidonax. 



393. O. imber'be. (Lat. imberhis, 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 upjjer tail-coverts. 

 Below, pale dull gray, sometimes aluK)st grayish -white anteriorly, clearing on the belly and 

 under tail-coverts to pale yellowish. Wings and tail fuscous, wdth pale gray or whitish edgings 

 of the middle and greater coverts and most of the quills of the wings, as in an Emjjidonax. 

 Bill dark brown 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. Very small : length 

 about 4.25 ; wing 2.10; tail 1.80; bill scarcely 0.30 ; tarsus 0.55; whole foot scarcely 1.00.

 slender, narrow at base, much as in Sayiornis. Wings moderate, pointed ; 2d-4th quills 

 longest, 1st between 5th and 6th. Tail nearly even, shorter than wings, of broad feathers. 

 Tarsus scarcely longer than middle toe and claw. A tropical genus of several species, one of 

 which reaches our border.

 parts gray ; all the feathers may be skirted with whitish, especially 

 on the wing-coverts and inner secondaries; tail quite blackish ; under 

 parts more purely white than in the 9 > and rather speckled than

This is a miscellaneous assortment (in scientific language, "a polymorphic group") of 

 birds of highly diversified forms, grouped together more because they differ from other birds in 

 one way or another, than on account of their resemblance to one another. As commonly received,
