330 Rockwell and Wetmore, Birds of Golden, Colorado. [}^ 



grant. Noted once May 16, and in the fall seen from October 10 to 

 November 1 in the open flat between the foothills and the hog-back. These 

 birds were all seen in the air and were not observed feeding. 



92. Oreoscoptes montanus. Sage Thrasher.— August 1 we found 

 a few of these birds in the scattering bushes on South Table Mountain. 

 They were very shy and were seen at a distance perched in the bushes, 

 looking like big wrens. Two immature birds in juvenal plumage were 

 taken but we found it impossible to secure any of the adults. They were 

 not seen again but will probably be found occurrmg locally in similar 

 locahties. 



93. Dumetella carolinensis. Catbird.— Tolerably common along 

 Clear Creek during the spring migration and a few remained for the sum- 

 mer. Last seen September 7. 



94. Salpinctes obsoletus obsoletus. Rock Wren.— Common 

 summer resident on rocky hillsides. First seen May 2 when it was fairly 

 common and part of the birds appeared to be mated. They were more 

 often heard than seen and usually scolded and sang from among rock shdes 

 and boulders above or below us where it was useless to follow them. On 

 South Table Mountain they were more abundant than anywhere else and 

 were also tamer than usual. A yqung Rock Wren just old enough to fly 

 was taken by hand because of its weakened condition, and upon examina- 

 tion was found to be infested with large white grubs several of which had 

 buried themselves deep into the bird's head and were gradually sapping 

 its vitahty. These grubs were nearly one half inch in length and were 

 aU buried out of sight under the skin. All the birds in the brood with the 

 exception of this one were apparently fine healthy specipiens. The last 

 birds of the year were taken at the base of North Table Mountain October 2, 

 where they were probably migratmg as they were unusually silent . 



95. Catherpes mexicanus conspersus. CAffoN Wren.— On April 

 11 we found two of these birds in Magpie Gulch north of Clear Creek Canon. 

 They were on a rocky hillside about 400 feet above the bottom of the 

 Gulch and our attention was attracted to them by the clear song of the 

 male, barely audible above the rushing of the snow water at our feet. We 

 secured one of these birds, the male, but lost the other. Another was seen 

 back of Lookout Mountain on May 24 and on July 25 we heard a male 

 singmg from a rock shde in Coon Gulch, but could not get to it. August 1 

 we took an unmature female on South Table Mountain in full plumage and 

 these constitute our records for this bird. It has been noted from this 

 region before by Mr. Test of Golden and this is one of the most northern 

 locahties in the state where it has been found, though Mr. L. J. Hersey 

 notes that it is common in Boulder Canon. The presence of the bird 

 here in July and the capture of the young bird in August that had just 

 attained full plumage would tend to show that it bred here. 



96. Troglodytes aedon parkmani. Western House Wren. 



Fairly common summer resident. First seen May 9, and fairly common 

 then in the mountains. They nest commonly in bird-boxes and nooks
