Male in first winter (immature) plumage: Similar to adult 

 male in nonbreeding plumage, but often with some of juvenal remiges 

 and rectrices, which are paler, Buffy Brown, as compared with deep 

 Buffy Brown to Clove Brown in older birds, and also often with tinge 

 of ashy gray on midoccipital area and nape. These differences 

 may be due to mcomplete postjuvenal molt and might have disap- 

 peared in the specimens exhibiting them had they lived a week or two 

 longer. 



Juvenal male: Lores, crown, occiput, nape, chin, throat, cheeks, 

 and auriculars pale grayish Hair Brown. Auriculars and circumocular 

 area tinged with Tawny-Olive. Upper back similar to nape but 

 slightly more tawny. Back, lower back, rump, upper wing-coverts, 

 and upper tail-coverts grajash Buffy Brown. Remiges Olive Brown, 

 externally edged with Tawny-Olive. Rectrices similar but with 

 less Tawny-Olive edgings. Breast, sides and flanks Hair Brown 

 tinged with Tawny-Olive. Center of abdomen, vent, and under 

 tail-coverts whitish. Under mng-coverts pale tawny gra3dsh buffy. 

 Iris brown. BiU and feet light brown. This plumage appears to 

 be replaced by the first winter plumage by the time the l)ird is 8 

 weeks old (at least in captivity, as described by Lloyd, 1955).
