EMPIDONAX MINIMUS (Baird). 

 LEAST FLYCATCHER. 



Closely similar in coloration to E. tmillii alnorum, but decidedly 

 smaller, and tail emarginate instead of even or slightly rounded. 



Adults (sexes alike). — ^ Above plain brownish olive, the feathers of 

 pileiim darker centrally; tail grayish brown, the rectrices passing 

 into light brownish olive on edges; wings dusky, the middle and 

 greater coverts broadly tipped with pale grayish brown or brownish 

 gray, sometimes nearly white on tips of greater coverts, forming 

 two distinct bands; the secondaries edged (except basally) \\dth the 

 same or with dull yellowish white; a broad dull wliite or yello\\-ish 

 white orbital ring; lores dull whitish suffused with dusky, especiall}^ 

 near anterior angle of eye; rest of side of head and sides of neck 

 similar in color to upper parts, gradually fading below into dull white 

 or grayish yellowish wliite of chin and throat; rest of under parts 

 dull white, more or less tinged with pale (primrose) yellow posteriorly, 

 the chest and sides more or less strongly shaded with pale grayish 

 brown or browjiish gray, this deepest on sides of chest and sides of 

 breast; axillars and under wing-coverts ver}" pale 3'ellow or yellowish 

 white ; inner webs of remiges edged with pale dull buffy or dull buffy 

 white; maxilla dusky brown, mandible pale brownish; iris brown; 

 legs and feet blackish brown or brownish black. 



Young. — Similar to adults, but wing-])ands diUl buff, and gray of 

 chest and sides more brownish. 



« I have not been able to examine in this connection the type of this supposed 

 species, but the principal character ('outer web of the exterior rectrix white") is one 

 which occasionally occurs in E. traillii alnorum.
