148 THE CONDOR VoL. X along the river. Later and more numerously, in the mountains. A yellow-shafted one was seen but not secured, so its identity remains doubtful. Chordeiles virginianus henryi. Western Nighthawk. A few seen during spring and summer. Trochilus alexandri. Black-chinned Hummingbird. Fairly common near the river, tho more numerous among the pinyohs and junipers of higher altitudes. Selasphorus platycercus. Broad-tailed Hummingbird. Not common. Only a few seen. Tyrannus verticaHs. Western Kingbird. Common, nesting in all the groves. Tyrannus vociferans. Cassin Kingbird. A few seen in early spring, appar- ently not nesting. Myiarchus cinerascens. Ash-throated Flycatcher. Abundant everywhere and 'nesting in deserted woodpecker holes. Sayornis saya. Say Phoebe. Not numerous, but a few seen thruout the coun- try from the river to the mountains. Contopus borealis. Olive-sided Flycatcher. Quite numerous .during spring migration. The first was seen May 19, and the latest date wag June 16, when three were noticed. Empidonax wrightii. Wright Flycatcher. Noted frequently during April and May. 0tocoris alpestris leucoliema. Pallid Horned Lark. Common everywhere. A certain place in the river, where the water spread out and formed several small streams, was a favorite watering place, and flock after flock came to drink every day. All springs on the mesas and plains were frequented by these larks in great numbers. Pica pica hudsonica. Black-billed Magpie. Common all along the river and nesting everywhere, even in trees in the school yard. I was much interested in a one-legged old "maggie," we called her Peggy, who was building in a tree just in front of my window. I was told that she had nested near the buildings the three years preceding. The old nests were much in demand for roof-trees by the English sparrows, and to a less degree by house finches. But I thought the limit was reached when we found in one, a nest of four young of Felis domeslica (pussy-cat). They were discovered by seeing the kittens peering from the nest which was six- teen feet from the ground. Cyanocitta stelleri diademam. Long-crested Jay. Several seen among the pines and spruces in the mountains in July. Apheloc0ma woodhousii. Woodhouse' Jay. One seen on the La Plata river in February. Two seen in the pinyons on the Chusca mountains in July, and two at Shiprock in August. They seem erratic in their range. Corvus corax sinuatus. American Raven. Fairly common; nesting on bluffs along both sides of the river. 31ucifraga columbiana. Clarke Nutcracker. Two seen in the Chuscas in Oc- tober, 1906, and a young male secured near the same spot in July, 1907. Cyanocephalus cyanocephalus. Pinyon Jay. Two small flocks seen at Shiprock. I found the birds quite common in the pinyons and junipers on the hill. Molothrus ater. Cowbird. Common. An egg found in a western gnatcatch- er's nest along with two of the rightful owner's eggs. Xanthocephalus xanthocephalus. Yellow-headed Blackbird. Seen occasionally near the barn yards. Agelaius ph?eniceus. Red-winged Blackbird. Seen frequently on flooded land.
