tail comparatively short, between -7 and -8 in the wing; even or 
slightly rounded. Plumage with the under wing-coverts yellow or 
pink, and the wings and tail marked with white. 
Two species only of this genus are generally recognized ; it ranges

South America.

Description.—Male—General colour above, including the sides of 
the head and throat black ; rump, a patch at the base of the primaries, 
tips of some of the coverts and tertiaries, subterminal patches on the 
inner webs of the three outer pairs of tail-feathers, all white ; chest, 
axillaries and under wing-coverts rose-pink, rest of the lower-surface 
white ; iris brown, bill light brown, dusky terminally, legs greyish- 
horn. Length 6-75; wing 4-0; tail 2-90; culmen -70; tarsus -80. 
The male in winter has the head and back brown, streaked with 
black, the under-parts pale brown, somewhat streaked with dusky. 
The female has the axillaries and under wing-coverts yellow, instead 
of rose-pink, and the wings and tail brown instead of black. 
Distribution.—Breeding in eastern North America from Manitoba 
to Nova Scotia southwards to North Carolina in the mountains, south 
in winter to Ecuador and Colombia through Cuba, Jamaica and Mexico. 
The status of this bird as a Colorado species rests on two occurrences. 
In the summer of 1894 a pair nested near the house of Mrs. J. W. Bacon 
at Longmont, in Boulder co.; the young were hatched and one was 
secured ; Burnett saw a pair on June Ist, 1902, near Loveland, and 
secured the male. Goss states that it is not a common bird except 
on migration in eastern Kansas, and that he has not met with it west 
of Junction City in the middle of the State.
