Notes on the Plumage of North American Sparrows 



SEVENTEENTH PAPER 



By FRANK M. CHAPMAN 



(See Frontispiece) 



Pine Grosbeak {Pinicola enucleator). In nestling plumage the Pine 

 Grosbeak, of both sexes, resembles the adult female, but is less strongly tinged 

 wdth yellowish. At the postjuvenal molt, the wing-coverts and feathers of the 

 body are shed, only the wing and tail-feathers being retained, and the bird 

 passes into first winter plumage. The female is now indistinguishable from 

 adults of the same sex, but the young male assumes a distinctive dress, well 

 shown by figure 3 of the frontispiece. This, it will be obsen^ed, resembles that 

 of the female, but the head and nmip have a reddish tone, suggesting an 

 approach to the plumage of the adult male. 



There appears to be no spring molt, and the nuptial, or breeding, plumage 

 is acquired by wear which, as D wight has shown, has the effect of brightening 

 the general color of feathers through the loss of the barbules on the terminal 

 barbs. 



At the postnuptial molt, the young male acquires the reddish or pink 

 plumage of the adult ; but the presence of an occasional yellowish feather among 

 the upper tail-coverts gives e\-idence of comparative youth, and it is probable 

 that very highly colored males are at least several years old. 



The western races of this bird are the Rocky Mountain Pine Grosbeak 

 {Pinicola enucleator montana), the California Pine Grosbeak (P. e. calif arnica), 

 the Alaska Pine Grosbeak (P. e. alascensis), and the Kadiak Pine Grosbeak 

 (P. e. flammula).
