Sept., 1907 SOME BIRDS OF SOUTHWEST COLORADO 155 



Tyrannus verticalis. Arkansas Kingbird. Five seen one day and none after- 

 ward. Probably stragglers to that altitude. 



Tyrannus vociferans. Cassin Kingbird. A pair nested on the Fort I^ewis 

 mesa. 



Myiarchus cinerascens. Ash-throated Flycatcher. One seen in spring. 



Sayornis saya. Say Phoebe. Common, nesting on porches. Mr. Warren saw 

 them at Coventry, and in Montezuma County. 



Contopus borealis. Olive-sided Flycatcher. A few seen. 



Contopus richardsoni. Western Wood Pewee. Two seen during the spring. 



Empidonax hammondi. Hammond Flycatcher. A few noticed and one 

 nest found. 



r leucolaema ~\ Horned I^ark. Just what part of our alphabet 



Otocoris alpestris j arenicola y to annex here I do not know. I saw horned 



(arcticola ) larks in the spring between Cortez and 



Navajo Springs. In winter I saw flocks of them at 9500 feet in the I^a Plata 



mountains. I secured a few specimens but they were accidentally destroyed. The 



summer birds I placed as leucolcema and the winter birds as aj'cticola. 



Pica pica hudsonica. Black-billed Magpie. Found along all streams in 

 southwestern Colorado. 



Cyanocitta stelleri diademata. I,ong-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. 



Aphelocoma woodhousei. 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. 



Perisoreus 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 corax 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 columbiana. 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 locality 

 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
