feeding", and one would have thought it wiser to take chances on the bugs, and 
let the swallows eat the other insects. Seen at Steamboat Springs and south of 
there. August 3, about three miles south of Phippsburg, I saw a flock which 
must have consisted of several hundred birds. At one time most of them perched 
on some service berry bushes, which they almost covered. A good many were 
seen at Kremmling. A few nests were seen on rocks in a railroad cut just out- 
side of Sulphur Springs. Noted at Fraser, and west of Golden.

served at Chambers Lake, where it was common, as also on the North Park side 
of Cameron Pass, and along the road to Walden. It was at Hell Creek and seen 
flying at high altitudes about Mt. Zirkel. Noted at Buffalo Pass saw mill. Near 
Steamboat Springs, July 28. I saw one enter a hole in a dead aspen by the road- 
side; presumably it had young there. Observed at Steamboat Springs, and at 
various places between there and Coulter.

eight miles west of Elbert. At Bijou Creek, IMay 22, I found a nest containing 
five eggs in a willow. Seen frequently between Bijou Creek and Simla, and was 
at Cedar Point. A few miles west of Agate we found a nest with five fresh eggs ; 
this was also in a willow. Seen near Fort IMorgan, and at that place Durand 
discovered a nest with se^•en eggs ; this was in a cottonwood on the fair grounds.

88. Anthus rubescens. Pipit. Seen on the mountains about Cameron 
Pass, June 23; 1 thought from their actions they were but just mated. It was 
common about Alt. Zirkel, where, on July 11, I saw one with an insect in its 
bill, and acting as if it wished to feed its young, but it would not go to the nest 
while 1 was about. One seen at Buffalo Pass.
