378 Birds of Colorado 
pink, leaving a narrow strip of white along the centre of the abdomen; 
bill pinkish, tipped with dusky, legs horn-brown. Length 6.10; wing 
3.30; tail 3.0; culmen -.48; tarsus .70. 
The female resembles the male, but is smaller—wing 2.9; the young 
bird has the crown and hind-neck washed with drab and the chest 
with pinkish. 
Distribution.— Breeding in Idaho and Montana and migrating south- 
wards to Arizona, New Mexico and the neighbouring portion of Old 
Mexico. In Colorado the Pink-sided Junco is an abundant winter bird, 
especially along the eastern base of the Rocky Mountains, where, it 
abounds from the end of October to the middle of April; the earliest 
and latest dates for El Paso co. in the Aiken collection are October 24th 
and April 24th, but Mr. Warren tells me he has seen and obtained 
specimens as early as September 22nd on the Sapinero Creek in Gunnison 
co., and as late as May 5th at Sulphur Springs. Dennis Gale observed 
this species at Ward in Boulder co., at an elevation of 10,000 feet, in 
early April, so that it is by no means confined to the plains. 
Other recorded localities are: Clear Creek co., up to 9,500 feet 
(Trippe), Orchard, March 26th to 28th (Warren), Pueblo (Beckham), 
Fort Lyon (Thorne apud Cooke), Wet Mountains up to 8,500 feet 
(Lowe), Mesa co. (Rockwell), San Juan co. (Drew), and Fort Lewis 
(Gilman). 
Habits.—The Pink-sided is perhaps the largest con- 
stituent of the winter flocks of Juncos in El Paso co. 
It has no characteristics distinguishing it from the 
other species. 
Grey-headed Junco. Junco caniceps.
