Species. 



Common Characters. — Adult males in spring and summer : Above varying from 

 vinaceous-gray to tawny cinnamon, the back and scapulars grayer or bi'owner, and 

 more or less distinctly streaked with darker ; a broad patch covering fore-part and 

 sides of crown, lores, patch beneath eye (covering also anterior and lower portion 

 of ear-coverts), and patch across chest, uniform black ; bar or band across forehead 

 and extending backward as a broad superciliary stripe, middle portion of ear- 

 coverts, malar region, chin, throat, and sides of neck, varying from pure white to 

 deep primrose-yellow, the hinder portion of ear-coverts more or less distinctly gray- 

 ish ; sides (especially of breast) vinaceous or cinnamon, like nape, etc., the flanks 

 usually somewhat streaked ; rest of lower parts usually white, but sometimes (in 

 0. giraudi and 0. strigata") pai'tly or even wholly pale yellow ; wings (except lesser 

 and middle coverts) grayish brown, the feathers edged with paler; tail (except 

 middle feathers) black, the outer web of exterior feather chiefly white, and that of 

 next feather edged, toward tip, with same. Adidt males in fall and winter : Essen- 

 tially like the foregoing, but black markings of head more or less obscured by 

 light-colored tips to feathers, the plumage generally softer and colors more blended, 

 the chest often streaked, clouded, or washed with grayish. Adult females: Similar 

 to males, but decidedly smaller, with black head-markings much less distinct (that 

 on top of head never well defined or continuous), the bold pattern of these mark- 

 ings as seen in the male seldom more than merely indicated ; vinaceous or cinnamon 

 tints of males much less pronounced (sometimes almost wholly wanting), and 

 plumage generally more extensively streaked. (Seasonal differences as in males.)
