BIBDS OF NORTH AND MIDDLE AMERICA. 463 



Young. — Coloration very different from that of adults. Scapulars 

 and wing-coverts margined terminally with bright rusty or tawny, 

 the greater and middle coverts sometimes with distal portion exten- 

 sively of this color; hindneck nearly concolor with back, the sides 

 of neck lighter brown with tawny margins to feathers (more or less 

 distinct); foreneck and chest light tawny-olive, passing into pale 

 buffy on posterior under parts. (Described from Mexican specimens, 

 in which a considerable portion of the adult plumage has appeared, 

 the crown and occiput being mostly deep gray, as in adults.)
