Sept., x9o 7 SOME BIRDS OF SOUTHWEST COLORADO I55 Tyrannus verticalis. Arkansas Kingbird. Five seen one day and none after- ward. Probably stragglers to that altitude. Tyrannus v0ciferans. Cassin Kingbird. A pair nested on the Fort Lewis mesa. Myiarchus cinerascens. Ash-throated Flycatcher. One seen in spring. Say0rnis saya. Say Phoebe. Common, nesting on porches. Mr. Warren saw them at Coventry, and in Montezuma County. C0nt0pus b0realis. Olive-sided Flycatcher. A few seen. C0nt0pus richards0ni. Western Wood Pewee. Two seen during the spring. Empid0nax hamrn0ndi. Hammond Flycatcher. A few noticed and one nest found. (leuc01a?rna) Horned Lark. Just what part of our alphabet 0t0c0ris alpestris ?arenic01a ? to annex here I do not know. I saw horned (arctic01a ) larks in the spring between Cortez and Navajo Springs. In winter I saw flocks of them at 9500 feet in the La Plata mountains. I secured a few specimens but they were accidentally destroyed. The summer birds I placed as [eucolcvma and the winter birds as arcIt'cola. Pica pica huds0nica. Black-billed Magpie. Found along all streams in southwestern Colorado. Cyan0citta stelleri diademata. Long-crested Jay. Numerous at and near Fort Lewis during winter of 1906. In 1907 up to January 31, only three were seen. Three pairs nested on the Fort Lewis mesa, but most of them went to higher alti- tudes. Early in May I found a nest near the end of a limb of a pine tree. It was about 10 feet from the tree trunk and 15 feet from the ground. May 13, the bird, a close sitter, was flushed from the nest and four eggs uncovered, one slightly cracked. Nest similar in construction to that of the Blue-fronted Jay. June 24, I saw young birds, just from the nest, at 10,000 feet altitude in the La Plata Mountains. Aphe10c0ma w00dh0usei. Woodhouse Jay. Very numerous during months of January, February and March, 1906. All except one bird disappeared during April. I saw none during the nesting season. Up to January 31, 1907, none were seen except two down the La Plata River near the New Mexico line. Peris0reus canadensis capitalis. Rocky Mountain Jay. Seen only at timber line on the La Plata Mountains, and not common there. Saw a pair, with four young, flying about searching logs and fallen trees for food. Young were very tame but adults shyer. This was on July 22. Corvus c0rax sinuatus. American Raven. A few spent the winter at Fort Lewis sharing with magpies and crows stolen scraps from the pig-pen. Two or three pairs seen during the breeding season but no nests found. Mr. Warren states that they are common at Cortez and Coventry. Corvus americanus. American Crow. Common all winter and a few seen in spring and summer tho no nests found. Some of the birds were quite tame in severe weather. Mr. Warren reports them common at Coventry at times in the fall. Nucifraga c01umbiana. Clark Nutcracker. Occasionally noticed in the winter. March 11, 1906, I saw a pair in Pine Gulch about two miles west of Fort Lewis and at about the same altitude. One of them was busily engaged in assault- ing a pair of Red-tailed Hawks that sat in the top of a dead pine tree. More than a foot of snow covered the ground at this time. May 1, I saw in the same loc?ility a pair of nutcrackers accompanied by three young ones. They followed the old birds begging for food in tones that could be heard half a mile or more. I saw them again a week later, discovering them both times by the vociferous begging of
