 96 THE CONDOR Vol. XIV 44. 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 Au!t. 45. Sayornis sayus. Say Phoebe. Seen at various places from Elbert to Fort 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 Butteg 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 west of the Buttes, built under the overhanging rocks. The species was noted near Fort Collins, and not again nntil about ten miles above Kremmling. 46. Myiochanes richardsoni. Vrestern Wood Pewee. At Fort Collins a pair had a half-finished nest in a willow overhanging our tent. At Steamboat Springs there was a nest 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 ve caught one and pho- tographed it. It could not quite fly. This was July 28. 47. Empidonax trailli. Traill 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 leucolema. Desert Horned Lark. Horned Larks were common everywhere from Colorado Springs to Fort Collins, and were often about the only birds to be geen on the high prairies between Deer Trail and Fort Morgan and the latter plac4 ariel Pawnee Buttes. A good many well g. rown }*ouag. xvre seen May 23 and .g4i one just able to hop around seen May 31, and a very sma!! one June 3; June 11 a 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 first met with eight miles south of Walden, and was com- mon at that g!.ace, 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, ve 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. Magpie. Magpies wer, e 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. We 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 Hell Creek. At the Mt. Zirkel camp several came about for scraps, but were rather shy. It was about the Buffalo Pass camp.
