in the Pink-sided Junco. I have nothing authentic concerning its nests and eggs 

 which more than likely do not differ materially from those of other Juncos. 



569. GBAY-HEABED JUHCO. Juneo caniceps (Woodh). Geog. Dist. — Rocky 

 Mountain district, from the Black Hills to the Wasatch and other Mountains of Utah, 

 south to Mexico and Arizona. 



The Gray-headed Snowbird is a common breeder in the mountainous regions of 

 Central Colorado and Utah southward, nesting in June, July and August, raising 

 ' two, perhaps three broods in a season. Its nest resembles that of Junco annectens, 

 being built on the ground In sheltered positions. The eggs have a difference In 

 ground-color varying from white and pinkish-white to bluish or greenish-white, 

 very faintly dotted (the markings being very minute) over the whole surface but 

 chiefly at the larger end with reddish-brown. A set of four eggs of this Junco is 

 in the collection of Mr. C. W. Crandall, of Woodside, N. Y. They were taken June 

 12, 1896, near Beulah, Pueblo county, Colorado, by Mr. D. P. Ingraham. The bird 

 was shot and perfectly identified. The nest was placed just under the edge of a 

 haystack. The situation was at an altitude of. about 8500 feet. The eggs measure 

 as follows: .76x.61, .77x.60, .74x.61, .76x.61, .76x.60 inches respectively.
