Vireo bellii, AUD. (Dacota.)

The above description is taken from a type specimen received from 
Mr. Audubon, and represents the average spring plumage. Autum- 
nal skins are rather brighter, and there is occasionally an ochraceous 
tinge on the white of the under parts. 
This species at first sight appears like a miniature of V. gilvus, 
the head being almost exactly similar. The back is, however, much 
brighter olive, the sides and crissum deeper yellow. The superciliary 
light stripe is shorter. The white markings of the wings are want- 
ing in gilvus. The wing, tail, and feet are entirely different in their 
proportions.
