" Tanagra columbiuiia, Jard. ed . Wilson, I, 317." According to Sclater, but I cannot find such name. 
Sp. Ch — Bill shorter than the head. Tail slightly forked ; first three quills nearly equal. Male, yellow ; the middle of the 
back, the wings, and the tail, black. Head and neck all round strongly tinged with red ; least so on the sides. A band of 
yellow across the middle covarts, and of yellowish white across the greater ones ; the tertials more or less edged with whitish. 
Female, olive green above, yellowish beneath ; the feathers of the interscapular region dusky, margined with olive. The wings 
and tail rather dark brown, the former with the same marks as the male. Length, 7.25 •, wing, 3.60 ; tail, 2.85. 
Hab.— From the Black Hills to the Pacific ; south to Mexico. 
It is not often that the male of this species is found in the highest state of plumage. Generally 
the feathers of the back are margined with olive, this color also tinging the yellow of the back, 
and the edges of the quills. The red of the head varies in intensity. The bill is rather smaller 
and slenderer than in P. rubra, although it varies considerably with the specimen. . 
The female can always be distinguished from that of rubra by the slenderer bill. The bill is 
much smaller than in P. aestiva. From both it differs in the whitish or yellow bands on the 
wings, and the back being duskier than the remaining upper parts. 
A young bird exhibits traces of brown in the yellow, and some faint dusky streaks. Young 
males have the general plumage of the female. 
The black back distinguishes this species from the somewhat similar P. erythrocephala and 
rvhriceps.
