THE COX DOR 
Vol. XIV 
-14. Tyrannus vociferans. Cassin Kingbird. This bird was observed 
exclusively on the Divide and on the plains, from East Bijou Creek to River Bend, 
and thence west to a little beyond Agate. The only other seen was several miles 
east of Ault. 
45. Sayornis sayus. Say Phoebe. Seen at various places from Elbert 
to Port Morgan. May 31, several miles south of the latter place, a nest contain- 
ing five eggs was found in a vacant house by the roadside. Two were fresh, the 
others in an advanced stage of incubation. Another nest found the same day 
was under a bridge, and we could look into it through a crack between the 
planks : there were three newly hatched young and two eggs. At Pawnee Buttes 
there was a nest in a small cavity in the creek bank near our camp, and I found 
another containing four eggs which appeared to be perfectly fresh in the bluffs 
wc.st of the Buttes, built under the overhanging rocks. The species was noted 
near Fort Collins, and not again until about ten miles above Kremmling. 
46. Myiochanes richardsoni. A'estern Wood Pewee. At Fort Collins 
a pair had a half-finished nest in a willow overhanging our tent. At Steamboat 
Springs there was a ne,st in a cottonwood close to the camp ; this contained well 
grown young, and we saw the parents feed them. Durand climbed up with the 
camera, and the three youngsters scrambled out. Later we caught one and pho- 
tographed it. Tt could not quite fly. This was July 28. 
47. Empidonax trailli. 4'raill Flycatcher. Taken near Log Cabin. It 
seemed to be common at Chambers Lake, and also at our Cameron Pass camp. 
It was also noted at the Buffalo Pass sawmill. 
48. Otocoris alpestris leucolasma. Desert Horned Lark. Florned Larks 
were common everywhere from Colorado Springs to Fort Collins, and were often 
abemt the only birds to be seen on the high prairies between Deer Trail and Fort 
IMorgan and the latter place and Pawnee Buttes. A good many well grown 
young were seen May 23 and 24; one just able to ho]) around seen May 31, and a 
very small one June 3 : June 11a few well grown young were seen. That day we 
often saw birds sitting in the shadow of a fence post out of the sun. In North 
Park the species was fiivst met with eight miles south of Walden, and was com- 
mon at that place, where young able to fly were seen June 28. It was abundant 
on the sage brush plains of the Park. Near Lake John, July 5, eve found a young 
bird, able to run, but not to fly. The species was observed on an Alpine plateau 
on Mt. Zirkel at 11,500 feet. It was seen near Toponas and Troublesome Creek. 
49. Pica pica hudsonia. IMagpie. Magpies were seen from Colorado 
.Springs to near Ramah ; none were noted after that until going west from River 
Bend, when some were seen near Agate. Durand saw one at Fort Morgan. The 
species was observed near Fort Collins, and beyond as far as Log Cabin. In the 
North Park it was seen south of Walden and was common at that place; it was 
noted at two or three camps on the west side of the Park. AVe saw it at Steam- 
boat Springs, and noticed it frequently along the road between there and Denver. 
50. Cyanocitta stelleri diademata. Long-crested Jay. Seen but a few 
times: once in the pines on the Divide, then near Home P. O., near the Buffalo 
Pass sawmill. Steamboat Springs, and between Idaho Springs and Golden. 
51. Perisoreus canadensis capitalis. Rocky Mountain Jay. As was to 
be expected, seen only in the mountains : first on the Park side of Cameron Pass ; 
then near Hell Creek. At the Mt. Zirkel camp several came about for scraps, 
but were rather shy. It was about the Buffalo Pass camp.
