JUNCO CINEREUS VAR. CANICEPS. 143 



cow's and horse's hair was also used in the lining." It contained three 

 eggs, measuring 0.74 by 0.60, bluish-white, with blackish aud brown 

 spots of various sizes thickly sprinkled on the larger end. 



My own experience with this bird has been only in the winter time. 

 I found it extremely abundant in the mountains of Arizona, from the 

 middle of October until the middle of April; and loiterers remained 

 until May. I judge that it breeds in the neighboring higher mountains, 

 as the San Francisco and Bill Williams. In habits, it seemed the 

 counterpart of the familiar eastern bird. During pleasant, open weather, 

 it used to keep in the recesses of the woods and shrubbery, but in snow- 

 storms, and during severe weather, when seeds were scarce and hard to 

 find, it would come trooping about our tents, and especially aroutul the 

 stock corrals, gleaning a subsistence from the waste grain that dropped 

 from the feed-troughs of our horses. Under such circumstances it was 

 sometimes emboldened even to enter a vacant tent; and I caught sev- 

 eral alive by scattering some bread crumbs in a small "A "-tent stand- 

 ing near mine, the flap of which was fixed so it could be pulled down 

 with a string. Its ordinary note is a soft chirp, which I could not dis- 

 tinguish from that of the common Snow-bird ; in the spring, just before 

 leaving for its breeding-grounds, it has a rather pleasing song, also like 

 that of its eastern relative.

As observed in my late work, the descent with modification of all the described 

 forms of Juneo from a coumion stock, is undoubted if not untiuestionable, altliough the 

 diversion has become so great that it would be scarcely exi»edient to consider them all 

 as a single specit-s. The various I'orms may be re<lnceil to three, hiiiinalix.oriiioniis. and 

 canic'ps, with their varieties. The firstof tliese has no pinkish-rufous on the sides below, 

 and in full plumage the dark parts are nearly uniform blackish-plumbeous; the adult 

 female is grayer, even brownish, especially on the inner (piills, and the young of tijo 

 first autumn and winter are extensively brownish. Oreiionus has an opa(|ue. blackish 

 head, aud fore-parts sharply contrasted with reddish of the back, aud the white of the 



toiin the rustv-re<l extends over the upper surface of the wings, and the bdl is black
