316 Rockwell and Wetmore, Birds of Golden, Colorado. [july 



were common. The birds were very noisy through the first week in May 

 when nesting began, but during the summer months were not so noticeable . 

 By October the moult was over and they were in fuU plumage. Ten of 

 eleven specimens taken were submitted to Mr. H. C. Oberholser who 

 pronounced them all phaloena. There is some variation in measurements 

 and the smaller specimens are much paler than eastern birds. 



13. Asio wilsonianus. Long-eared Owl. — Occasional along Clear 

 Creek in early spring and late fall. Found nesting on Clear Creek about 

 four miles east of Golden, April 24 and May 15, 1901. 



14. Otus asio maxwellise. Rocky Mountain Screech Owl. — 

 This species was fairly common along Clear Creek up to the foothills, 

 where it is resident and breeds during April, but could be overlooked easily 

 on account of its retiring habits. A nesting female was noted April 3, in a 

 hole in a cottonwood. No owls were seen at all in the foothills and only 

 once did we find an " owl pellet " on Lookout Mountain. The single 

 specimen taken appears to be typical maxwellice. 



15. Bubo virginianus lagophonus. Great Horned Owl. — An 

 adult female taken October 2, in a gulch on North Table Mountain, was 

 the only one seen. This bird rose from some rocks on a side hill and when 

 shot fell with a broken wing. While we were endeavoring to capture it, 

 we noticed a strong odor of skunk and upon skinning the specimen we found 

 the stomach to be crammed with skunk hair and bones. This bird was 

 submitted to Mr. H. C. Oberholser who identified it as B. v. lagophonus, 

 making the second record for the state for this bird. 



16. Dryobates villosus monticola. Rocky Mountain Hairy 

 Woodpecker. — During the spring these birds were rare, and a female 

 taken April 25, in the barren hills north of Clear Creek was the only one 

 seen. On August 22 we saw a magpie in close pursuit of one on Lookout 

 Mountain. They darted in and out among the pines and as they passed 

 me, I dropped the woodpecker, finding that it was an adult female in 

 worn plumage. Two were seen September 19, and after this date they were 

 fairly common, several being seen on every trip. One taken October 2, 

 was in full plumage. A specimen was taken on Clear Creek below Golden, 

 November 6. 



17. Dryobates pubescens homorus. Batchelder's Woodpecker. 

 — Rather rare in the region included in this paper. One taken on Bear 

 Creek near Morrison April 14, and another noted April 16, on Clear Creek 

 below Golden. We made special search for this small woodpecker but 

 found it rarely. 



18. Sphyrapicus thyroideus. Williamson's Sapsucker. — Tolera- 

 bly common on Lookout Mountain during the first part of the fall migra- 

 tion, but none seen during the spring. This was one of the birds that came 

 into this region from the higher altitudes. An immature female taken 

 August 8, was the first one seen. This bird was still in first plumage and 

 both adults and young were moulting until the last of September when they 

 disappeared. They were seen only among the pines at 7500 feet, and were 

 very shy so that we probably overlooked some of them.
