SOME NORTH-CENTRAL COLORADO BIRD NOTES 
99 
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 ])hotographed. At 
Lake John I found near our camp a nest with three fair-sized young; going there 
the next day with 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 Steamboat Springs, and often seen between there and Arvada. 
68. Passerculus sandwichensis alaudinus. Western Savannah Sparrow. 
Seen at Walden; at the upper and lower bridges over the North Platte: about the 
meadows at Hell Creek. At various times small sparrows were seen about the 
flooded meadows in the Park, which were no doubt this species, but the super- 
abundance of mosquitos in 
those places did not encour- 
age one to investigate very 
closely. 
69. Chondestes grammacus 
strigatus. \\"estern Lark Spar- 
row. Seen near Fondis, at 
River Bend and Cedar Point. 
At the latter place. May 77, 
while the birds seemed to be 
mated, they were not yet nest- 
ing. It was noted a few times 
between River Bend and Deer 
Trail, and then at Fort Mor- 
gan, W'ild Cat Creek, Pawnee 
Buttes, and from there to Fort 
Collins, and thence to near 
Log Cabin. Seen several times 
between Steamboat Springs 
and Toponas. and near Golden. 
70. Zonotrichia leucophrys. 
Wdaite Crowned S p a r r o w. 
First seen at Chambers 
Lake, and was rather common at the Cameron Pass Camp. It was 
common about Mt. 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 almost 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 ne.st itself was well hidden. She was on 
the nest and flew off the day we discovered it. The nest was about two feet 
above the ground, and built mostly of fine grass. The species was noted at the 
Buffalo Pass saw mill, where it was quite tame and familiar, and was also at 
Buffalo Pass. Seen several miles .south of Yampa, at Rock Creek on the Gore 
Pass road, east of Coulter, and on \Msquez Creek. 
71. Spizella passerina arizonae. \\Tstern Cliiiqung Sparrow. May 19
