Species. 



COMMON CHARACTERS. Adult males with the plumage* partly or chiefly red- 

 dish ; adult females olivaceous or grayish above, streaked with darker, beneath 

 whitish, conspicuously streaked with dusky or brownish gray. 



a 1 . Tail very much shorter than wing, deeply emarginated ; adult males with wing- 

 feathers edged with reddish. Nest a rather flat, thin structure, composed of 

 fine dry rootlets, grasses, etc., on horizontal branches of trees. Eggs 2-4, 

 greenish blue or bluish green, finely speckled, chiefly on larger end, with 

 black and dark brown. (Subgenus Carpodacus.*) 



b l . Lower tail-coverts without distinct dusky streaks; depth of bill through 

 base equal to or greater than length of gonys. Adult males : Above dark 

 dull madder-pink, clearer on rump, deeper and brighter on top of head, 

 the back more or less obscured by darker centres to feathers, and often 

 (especially in winter) by grayish edgings ; feathers of back streaked me- 

 dially with dusky; lower parts, except belly and lower tail-coverts, 

 dull madder-pink, the sides strongly tinged or washed with this color. 

 Adult females : Above olivaceous, mixed with grayish, and streaked with 

 darker; sides of head with two distinct brownish stripes, or patches, one 

 covering ear-coverts, the other on each side of throat, the two sepa- 

 rated by a whitish maxillary stripe ; lower parts dull white, conspicu- 

 ously streaked with dusky. Young : Similar to adult female, but colors 

 duller, markings less distinct, and edgings of wing-feathers more buffy 

 or tawny.

 flanks usually not tinged with brown, and not distinctly streaked ; 

 if streaked, the streaks usually narrow, and sharply defined ; back 

 more distinctly streaked, red of crown brighter, and that of rump 

 paler and clearer. Adult female : Top of head and back distinctly 

 streaked ; streaks of lower parts broader, darker, and more sharply 

 defined. Length 5.50-6.25, wing (males) 3.15-3.40 (3.27), tail 2.30-
