BIRDS OF NORTH AND MIDDLE AMERICA 307 



of the same; secondaries smoky hair brown becoming white on the 

 inner edge of the inner webs, barred and broadly but indistinctly 

 tipped with fuscous, the terminal band narrowly tipped with pale 

 hair brown; primaries fuscous-black becoming white on the inner 

 webs, the outer three feathers with the inner webs emarginated, the 

 outer webs of the primaries not or only indistinctly barred with black, 

 the inner webs barred v/ith five or six narrow blackish bends, these 

 bars incomplete on the four or five outermost feathers; rectrices dull 

 black, with an indistinct terminal band of dull hair brown, this fading 

 terminally into whitish; across the middle of the tail a broad band of 

 dull light umber nearly dull white, about 15-20 mm. broad; about as 

 far anterior to the main band as this is from the tip is another much 

 narrower and less distinct band of the same color crossing just beyond 

 the ends of the coverts, or concealed by them; lores whitish to dirty 

 buft'; cheeks benzo brown to fuscous, the feathers edged with pale 

 tawny or buffy mikado brown, giving a streaked appearance; a broad 

 but inconspicuous "mustache" running from the rictus downward 

 across the cheek, fuscous to fuscous-black; chin and throat white 

 sometimes tinged with buff, immaculate or sparsely penciled with 

 dark shaft streaks of buffy hair brown or dull Saccardo's umber to 

 fuscous; rest of underparts whitish, the breast feathers heavily streaked 

 and broadly barred (the bars being lateral dilations from the median 

 streaks) with from wood brown to snuff' brown and bister, sometimes 

 so extensively marked with this darker color as to appear almost 

 uniform snuff' brown or bister with a few whitish spots here and there; 

 upper abdomen and sides and flanlcs like the breast, but with the shaft 

 stripes reduced so that the feathers are more clearly barred, and with 

 the white interspaces larger, the brown marks becoming smaller 

 posteriorly; lower abdomen immaculate or only very slightly and 

 lightly marked with brownish; under tail coverts usually pure white, 

 occasionally sparsely and faintly marked with pale wood brown; 

 thighs lilce the sides, but with the brown marks paler and narrower; 

 under wing coverts whitish marked very sparsely with wood brown; 

 iris light reddish hazel; cere greenish yellow to chrome yellow; feet 

 light yellow; bill and claws bluish-black. 



Females average slightly darker generally than males, but the 

 extremes are the same for the two sexes. 



The adults show two general types of coloration, which, if not for 

 the completeness of all the intergradations shown by a good series, 

 would merit description as two color phases— a grayish brown-backed 

 form with little rufous or cinnamomeous on the feather margins, 

 and with the ventral markmgs dull brownish, and a darker form with 

 the feathers of the sides of neck and upper back edged with cinnamon
