376 Birds of Colorado 
The female is of a lighter shade of slate, and the second pair of tail- 
feathers are partially dusky, the third pair almost wholly so; it is 
also smaller—wing 2-90. Young birds have a distinct wash of brown 
on the back. 
Distribution.—Breeding from Alaska to Maine and northwards also 
south along the Alleghany mountains ; migrating south to the borders 
of the United States from Florida to California. 
In. Colorado the Slate-coloured Junco is a rather uncommon winter 
visitor, almost always found associated with other species of the genus ; 
it has been chiefly taken along the eastern base of the Rocky Mountains, 
and hardly ever penetrates into the mountains themselves; it was 
noted by Trippe up to 8,000 feet. The earliest date for El Paso co. 
in the Aiken collection is November 25th, but it is less abundant in 
the early part of the winter than on the spring migration, when it has 
been taken as late as April 25th. Other recorded localities are 
Boulder co. (Henderson), Clear Creek co. (Trippe), Pueblo 
(Beckham), Lamar, April 6th (Warren), Fort Lewis, January and 
March (Gilman). 
Habits. —A well-known winter bird in the east, but not 
at all familiar in Colorado, where it is always met with 
in flocks, mixed with the other Juncos. It has a cheery 
little chirp in winter, and in the north in its breeding 
grounds a pleasant song, not so often heard. 
Shufeldt’s Junco. Junco hyemalis shufeldti.

Description.—Male—Head, neck, and chest very dark slaty-black, 
very clearly marked off from the sepia-brown of the back, the white 
of the lower-breast and abdomen, and the cinnamon-pink of the sides 
and flanks ; wings and six central tail-feathers dusky ; two outermost 
pairs white, third pair partly white and partly black ; iris reddish-brown, 
bill pinkish, dusky at tip; legs light brown. Length 5.90; wing 3-15; 
tail 2-85 ; culmen -40; tarsus -80. 
The female has the black of the head replaced by a dull slate, and 
the crown is washed with sepia-brown so as to obliterate the distinct 
line of demarcation between the head and back.
