PASSERINE BIRDS OF NEW YORK 309 



coverts and tertiaries edged with tawny olive and darker tipped. Below, white, 

 strongly tinged on jugulum, less strongly on the chin, breast, sides and crissum 

 with tawny olive, heavily spotted or barred on the jugulum, faintly on the 

 breast and anterior parts and sides of the abdomen with clove-brown, the 

 feathers also barred with a subterminal tawny band. Submalar stripes dusky. 

 Bill and feet pinkish buff, remaining pale when older. 



3. First Winter Plumage acquired by a partial postjuvenal 



moult, beginning the middle of July, which involves the body 



plumage, and lesser coverts but not the rest of the wings nor 



the tail. 



Similar to the previous plumage but without the spotting above and the barred effect 

 below. Above, uniform deep russet or pale mummy-brown. Below, white, 

 olive-gray on the sides and llanks, and strongly tinged on the throat, neck and 

 jugulum with pale ochraceous buff ending abruptly on the breast, and sparsely 

 spotted on the jugulum and sides of the throat with pale sepia deltoid spots, a 

 few still fainter on the breast. Lores grayish white with dusky edgings ; or- 

 bital ring similar and not conspicuous. 



Young birds may usually be distinguished from adults by 

 the terminal buff spots of the retained ju venal wing coverts. 



4. First Nuptial Plumage acquired by wear, the buff be- 

 low and the spots fading a little, and the russet above becoming 

 grayer. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult in July. Young heretofore distinguishable by 

 Juvenal plumage, wing edgings and tippings become indistin- 

 guishable from adults, which lack them. Adults are of a deeper 

 less yellowish brown above. 



6. Adult Nuptial Plumage acquired by wear as in the 

 young bird. 



Female. — The sexes and moults are alike. 



Turdus aliciae Baird. Gray-cheeked Thrush 



1. Natal Down. No specimen seen. 



2. Juvenal Plumage acquired by a complete postnatal moult. 



Above, greenish olive-brown, wings and tail darker, the pileum, back, wing coverts 

 (except primary and greater) and rump with buffy white linear shaft streaks. 

 Below, white, very faintly tinged with pale buff on the breast and sides, the 

 breast and throat spotted with black tending to barring on forepart of abdomen
