 100 THE CONDOR Vol. XIV to 22 this species was common in the pines on the Divide, and about Elbert. Seen about fifteen miles south of Walden, and about the Buffalo Pass saw mill. It was also noted west of Golden. These seem very few notes for this common species, and I hardly know how to account for it. 72. Spizella breweri. Brewer Sparrow. Two or three were seen be- tween Fondis and Ramah, and I thought I saw one near Pawnee Buttes. It was a common bird in the sage brush in the North Park, being observed everywhere we went. June 26 a nest with four eggs was found in a greasewood bush near Walden; the eggs seemed to be somewhat incubated, and'the nest was empty when visited July 18. Another with four eggs was found at Lake John, July 6; these were but slightly incubated, as I found by dropping one while examining it. Durand found a nest with three eggs at Walden, July 21. The species was ob- served at Steamboat Springs and south of there as far as Toponas, where we turned off into the mountains. 73. Junco phaonotus caniceps. Gray-headed Junco. Seen at my first camp on the Divide, about four miles west of Eastonville, May 19; between Log Cabin and Elkhorn; Chambers Lake; west of Cameron Pass; fifteen miles south of Walden; Hell Creek; about Mt. Zirkel; near Buffalo Pass saw mill; Buffalo Pass; Gore Pass; east of Coulter; and in pines about ten miles west of Golden. 74. 19Ielospiza melodia montana. Mountain Song Sparrow. Noted at Elkhorn. A little below the Mt. Zirkel camp a nest with four eggs was discov- ered July 9. It was on the ground in a tuft of bunch grass; from the actions of the bird I am inclined to think the eggs were well incubated. One was seen at Buffalo Pass, one at Steamboat Springs, and one a few miles south of Yampa. 75. Pipilo maculatus montanus. Mountain 'powhee. One seen ne-r Log Cabin, and several in the foothills west of Golden. 76. Oreospiza chlorura. Green-tailed 'powhee. Seen May 19 on the Divide; at Bijou Creek; near Log Cabin and between there and Elkhorn; near Hell Creek; near Mt. Zirkel; at Grizzly Creek; Steamboat Springs; south of there to Toponas; above Kremmling; near and below Empire. 77. Zamelodia melanocephala. Black-headed Grosbeak. Observed at Fort Morgan/tnd Ault. 78. Passerina amcena. Lazuli Bunting. Seen west of the Forks, June 15. 79. Galamospiza melanocorys. Lark Bunting. 'Phis species was first noted May 19 on the Divide, when a few were seen. None were seen after that until about two miles east of Fondis, when it became common. It continued so practically everywhere until after passing the "Forks" in Larimer County, except that I saw none on Cedar Point, though it was on the prairies below. On the high prairie country between Deer Trail and Pawnee Buttes this species and the Horned Larks were often the only birds seen, and the latter were the more abundant. It was seen near Walden. Near Sidney P. O., Routt County, August 2, I shot a male Lark Bunting which is a peculiar partial albino. At first sight I took it for a Bobolink, for which I had been watching all the morning, as I had found them along that road four years before. The wing patches are normal in extent, but much tinged with rusty, and the feather of the back and upper wing coverts are edged with the same. The tail is decidedly rusty. Below the bird is about equally black and white, these colors, however, being unevenly dis- tributed, and presenting rather a curious appearance. Also noted near Yampa.
