SOME NORTH-CENTRAL COLORADO BIRD NOTES 9q below the Cameron Pass Camp; common in the sage brush in the North Park. June 30, between Walden and Hell Creek, a good many young were seen just able to run about; and July 5, while driving from the last-named place to Lake John, more were seen, including one which was captured and photographed. At Lake John I found near our camp a nest with three fair-sized young; going there the next day xvith the camera I found the nest empty, but a garter snake was found with a suspicious swelling in its middle, and executed. I meant to have- killed it so as to have preserved it for a specimen, but forgot myself and blew its head off. At the same locality, July 7, a nest with four small young was found. It was at Steam,at Springs, and often seen betxveen there and Aada. 68. Passerculus sandwichcrisis alaudinus. Western Savannah Sparrow. Seen at Walden; at the upper and lower bridges over the Noah Platte; about thc meadows at Hell Creek. At various times small sparrows were seen about the flded meadows in the Park, which were no doubt this scies, but the super- _ abundance of mosquitos in  '   ,' those places did not encour-  = _ - age one to investigate very I , .

JULY 11, 1911 XYhite Crowned  p a r r o w. First seen at Chambers Lake. and was rather common at the Cameron Pass Camp. It was common about Mr. Zirkel. where it ranged at least to timberline. July 11 we found a nest containing four eggs in a scrubby spruce at an altitude of 10,575 feet, just below timberline. An odd thing about this nest was that the day before we had set a mouse trap on the ground ahnost directly under the nest, and tied the marker to the bush over it. The bird must have flushed then without being noticed, or else was not sitting, and the nest itself was well hidden. She was on the nest and flew off the day we discovered it. The nest was about two feet ave the ground, and ilt mostly of fine grass. The scies was noted at the Buffalo Pass saw mill, where it was quite tame and familiar, and was Mso at Buffalo Pass. Seen several miles south of Yampa, at Rock Creek on the Gore Pass road, east of Coulter. and on Vasquez Creek. 71. Spizella passerina afizonm. Western ChApping Sparrow. May 19
