known to breed in the State, which is somewhat strange con- 
sidering how far south it breeds in the mountains of eastern 
United States. 
567b. Junco hyemaiis connectens. Shufeldt’s Junco. 
Winter resident; abundant. Great numbers winter in 
southern Colorado, where F. M. Drew says that they appear 
first at timber line in September; later, stragglers come down 
and mix with caniceps and by October have taken full possess- 
ion. When severe winter weather begins they pass lower 
down. (B. N. O. C. VI. 1881, 138.) They remain in numbers 
throughout the winter as far north as central Colorado, and are 
not an uncommon winter resident nearly to the northern 
boundary. Very common in migration during November and 
April. Extend eastward to Kansas. 
568. Junco mearnsi. Pink-sided Junco. 
Winter resident; common. In middle Colorado, during 
the winter, one of the most common Juncos, especially on the 
plains at the base of the foothills. Arrives rather late in the 
fall, and is most numerous during the spring migration. At 
this latter season it is principally a bird of the mountains from 
6,000 to 10,000 feet. The period of greatest numbers is about 
the first of April. The last of the migratiug Juncos to leave, 
remaining until the last of April. iViken once saw females in 
El Paso County as late as May 4. Extends east on the plains 
as far as Fort Lyon, where it has been taken by Capt. P. M. 
Thorne. 
568. I. junco annectens. Ridgw ay’s Junco. 
Winter visitant; rare. One was taken by R. C. McGregor 
at Boulder November 25, 1892, associated with 7 nearnsi^ cani- 
ceps^ aikejii^ and connecteits. (Auk, X, 1893, 205.) 
569. Junco caniceps. Gray-headed Junco. 
Resident; abundant. The only Junco at present known 
to breed in Colorado. The bulk winter south of the State, but 
a few remain on the plains and the lowest valleys of the mount- 
ains from November to April. In southwestern Colorado F. M. 
Drew says that they are very abundant in summer from 7,500 
to 12,000 feet, raising two and perhaps three broods. Large 
young out of the nest taken June 26, and nest with fresh eggs a 
month later; young birds September 25. The commonest 
summer bird, taking the place of the Chippy of the east. 
Leave the first of November just as oregonus — connectens^ be- 
comes plentiful. (B. N. O. C. VI. 1881, 138.) Farther north, 
in Clear Creek County, where it does not winter, T. M. Trippe, 
in “Birds of the Northwest,” says that it arrives the middle or
