tints of rubra, having them duller above, and slightly tinged with reddish beneath. The hill 
is much larger than in rubra, nearly equalling the head ; quite so in some specimens, varying 
considerably in size, as it does. Texas specimens generally appear to have larger bills than 
those farther east. 
The young male is like the female. Immature males, however, exhibit every gradation 
between the perfect colors of both sexe

I have at hand no full plumaged male of this bird, and have been obliged to borrow the 
description from Sclater, as cited above. The species is considerably larger than P. aestiva, 
with which it agrees somewhat in characters. The bill, however, is proportionally smaller, 
with more of a tooth on the commissure. The color, too, is bluish black, instead of light horn 
color with yellowish margins. The sides are tinged with ashy instead of being like the belly. 
The red is of a different shade, duller above, and the forehead conspicuously brighter than the 
back, instead of a meie shade lighter. 
According to Sclater the P. saira, (P. azarae, Auct.,) to which this bird was referred by Dr. 
Woodhouse, differs in being smaller, the bill bluer, the feet black, not brown, the red colors 
different. The female is also said to have a yellowish superciliary stripe.
