LEPTOPOGON SUPERCILIARIS Cabanis. 

 GRAY-CAPPED LEPTOPOGON. 



Adults (sexes alike). — Pileuin dusky gray or deep slate color (the 

 feathers indistinctly darker centrally or niesially), the hindneck 

 similar, but tinged with olive-green; back, scapulars, rump, and 

 lesser wing-coverts plain olive-green, the upper tail-coverts similar 

 but browner; tail deep grayish brown, the outer webs of rectrices 

 broadly edged with olive-green; wings (except lesser coverts) dusky, 

 the outer webs of middle and greater coverts with broad terminal 

 spots of pale olive-yellow or buff ;'^ primaries narrowly, secondaries 

 broadly, edged with light olive-yellow or yellowish olive, these 

 edgings much broader and clear primrose yellow on inner secondaries 

 ("tertials"); loral and suborbital regions pale grayish or grayish 

 white, flecked \\i\\\ dusky; a few wliitish dots or flecks at posterior 

 angle of eye; terminal portion of auricular region uniform black or 

 dusky, the anterior portion light olive or grayish with narrow shaft- 

 streaks of wliitish; chin and upper throat pale olive-grayish, passing 

 into light yellowish olive on lower throat, chest, and sides; rest of 

 imder parts light yellow (sulphur to primrose) ; axillars and under 

 wing-coverts similar; inner webs of remiges rather broadly edged 

 with yellowish white or pal(> buff; bill black or dusky with paler 

 tomia, usually with tip and base of mandible also pale; iris brown;* 

 legs and feet horn color or dusky in dried skins, pale bluish in life.^ 



Adult male.— hei\gi\\ (skins), 129-138 (133); wing, 65.5-68.5 (67.2); 

 tail, 57-63.5 (60.4); exposed culmen, 12-14.5 (13.2); tarsus, 15-16 

 (15.3); middle toe, 8-9 (8.7).« 



« I am unable to explain the significance of this variation in the color of the wing- 

 l)ands; but suspect that examples with these markings ])uff are youn^i-r birds, pcrlvips 

 in the first year, though certainly not in first plumage.
