Notes on the Plumage of North American Sparrows 210 



marked sfcasonal variations in plurrja;.^f;. The juvenaJ f^hjrnagc is esser)ii;illy 

 like .that of the adult but the brov/n cajj Is not evident, the buffy throat not 

 so pronounced, and the underf^arts are streaked with dusky. The post-ju venal 

 molt apjjears to resemble that of the other f^rown Towhees, that is, the body 

 plumage, tail, inner v/ing-quills, and all but the primary v/ing-coverts, are 

 replaced by the feathers of the first winter plumage, which, reseml^les the 

 winter plumage of the adult. 



There is apparently no .spring molt, and the differences between summer 

 and winter plumage are due to wear and fa/iing, which do not materially 

 alter the color of the plumage. - 



The San Lucas I'owhee (PipUo fuscus olhiyula) is a smaller, darker rac^; 

 with a white throat, which inhabits the Cape Kegion of Lower California, 

 north to latitude 2:9''. 



California Towhee ^Pipilo crisaaU^ criHsaliH, Fig. 3;. — 7'his species, 

 differs from the Canr^n Towhee in its deeper, richer coloration, which is par- 

 ticularly pronounced on the throat and under tail-coverts. 7'he sexes are 

 alike, and the young bird in juvenal pluma,ge resembles in general (^vloration 

 the adult, but lacks the brown ca,p, the throat is not so deeply of,»lore<'J, and 

 the underparts are strea.kerl with dusky. There are practically no .seasonal 

 changes in aJor, and the pluma,ge-changes appear to resemble those of the- 

 Canon Towhee. 



Anthony's Towhee (Pipilo cri:>%(M:, :.tnicida), a smaller form, with darker 



upperparts and less ochraceous on the underj^arts, ranges, axcording to the 



A. 0. U. 'Chieck-List,' from "Southern California south of the San Bernardino 



I Mountains, and on the Pacific side of Jy^wer CaJifomia south at least to lati- 



I tude i^''." 



I Abert's Tov/hee ( Pipilo oJjerli, V'v^. 4;. — In this sj^ecies the .sexes are 

 I alike, and there are but slight vari:ations in plumage due to age or season. 7"he 

 I juvenal plumage, while showing the usual difference in texture from that of 

 1 subser^uent plumages, is of the same general tone as that worn by the adult, 

 I but the underpa.rts are paler a.nd are faintly streaked with dusky. 



The postjuvenal molt apx>ears to include all the body feathers, the t^^ail 

 t and the inner wing-feathers, and in the resulting first-winter pluma.ge the 

 bird resembles the a/lult, with pink-tinged breast and blackish about the 

 [face. There appea,rs to be no spring molt, and bre^;/'ling specimens wear a 

 j very ragged plumage, which, a,side from being slightly paler, does not differ in 

 I color from thiit of winter.
