 brown, the larger small-coverts tipped with greyish-white, the secon-

A yoimg male, killed on the Columbia River, on the 21st June 1836 

 and in its first plumage, resembles the female in all the upper parts, 

 including the tail, of which the four outer feathers, however, are more 

 yellow. The loral space, and a streak on the throat, shorter and nar- 

 rower than in the old male, are black, the band on the eye, the cheeks, 

 the fore neck, and part of the breast, pale yellow ; the rest of the lower 

 parts as in the female.
