Sp. Cii. — Male. General color a rich dark purplish chestnut ; the top of the head, the thin, and middle of belly, tinged with 
brown. Crissum dark brown. Fore part of the back lighter, with two or three more or less interrupted concentric bars of dark 
brown. The feathers of rump and tail greenish brown ; the former edged with paler. Wing coverts and outer webs of 
some scapulars blue ; others dark velvet green, streaked centrally with yellowish buff. Edges of greater wing coverts white, 
as are the axillars and middle of wing beneath. Feathers of flanks uniform chestnut, without bands. Speculum metallic green. 
Female with the top of the head dusky and the wing coverts blue, as in the male ; the speculum duller. The upper parts 
dark brown, with lighter edges to the feathers. The under parts are brownish yellow, with a strong tinge of purplisli chestnut 
in the jugulum, the feathers with concealed spots of brown. The only feathers unspotted with brown on the head and neck are 
in small patches on each side of the base of the bill, and in the chin between the rami. There is an obscure dusky patch 
beneath the head. 
Length, 17.80 ; wing, 7.50 ; tarsus, 1.15 ; commissure, 2. 
Hob. — Rocky mountains to Pacific. Accidental in Louisiana. Spread over most of western South America. 
The female of this species is very similar to that of the common blue-winged teal. It is, 
however, rather larger, and the bill decidedly longer. The unspotted whitish of the head is 
more restricted ; the under surface of the head not pure whitish, but each feather with a 
brownish spot, producing a dusky patch. There is almost always a decided purplish chestnut 
tinge in the jugulum. The tertials are more elongated.
