Autumnal specimens and young birds are sometimes so strongly 
tinged with greenish-yellow as to be scarcely distinguishable from 
Hi. celata. The wing is, however, always longer, and the obscure 
whitish patch on the inner edge of the exterior tail feather, near its 
tip, is almost always appreciable. In celata this edge is very nar- 
rowly and uniformly margined with whitish. 
A young bird of the year, from Fort Simpson (27,228), has two 
distinct, greenish-white bands on the wings, and the forehead and 
cheeks greenish-yellow. A corresponding age of H. celata has the 
wing bands more reddish-brown, the wings shorter, and no white 
patch on the outer tail feather. 
It is possible that Mr. Sclater is mistaken in quoting this species 
from Oaxaca, the only Mexican locality mentioned by authors.
