JUNCO CANICEPS, Baird. 
Struthus caniceps, Woonnovss, Pr. A. N. Se. Phila. VI, Dec. 1852, 202. (New Mexico and Texas.)—Is. Sitgreave’s 
Report Zuni & Colorado, 1853, 83; pl. iii. 
Sp. Cu.—Bill yellowish ; black at the tip. Above dark plumbeous, the head and neck all round of this color, which extends 
(paling a little) along the sides, leaving the middle of the belly and crissum quite abruptly white. Lores conspicuously, but 
not very abruptly darker. Interscapular region abruptly reddish chestnut brown, which does not extend on the wings, except 
perhaps a faint tinge on some of the greater coverts. Two outer tail feathers entirely white ; third with a long white terminal 
stripe on the inner web. Length, 6.00; wing, 3.23 ; tail, 3.04. 
Hab.—Rocky mountains ; from Black Hills to San Francisco mountains, New Mexico. G 
This species is very similar to the common J. hyemalis in color, except that the plumbeous of 
the under parts and sides is not quite so dark and less abruptly defined against the white. The 
conspicuous chestnut patch on the back will distinguish them. The outer web of the third tail 
feather is brown, not white. It differs from oregonus and cinereus in having no chesnut on the 
wings, especially the tertials, and from the former in the extension of the ash of the neck along 
the sides. It is darker above than J. dorsalis, which also lacks the distinct plumbeous of the 
throat and sides, has the bill blacker, the lores more abruptly darker, &c.
