184 Cary, New Records of Colorado Birds. [ April 



Catherpes mexicanus conspersus. Canon Wren.— Noted at various 

 points in western Colorado in 1906-07, chiefly south of the Grand River 

 Valley. North (sparingly) to the lower White River Valley, indicated 

 by one which was heard among the rock ledges 20 miles east of Rangely, 

 September 12, 1906. The most eastern Colorado record for the canon 

 wren is Gaume's Ranch, northwest Baca County, where a specimen was 

 collected in Shell Rock Canon, November 27, 1907. Mr. E. J. Gaume 

 states that this wren is a regular breeder in the cliffs near his ranch. The 

 above locality is also important as marking the eastern limit of conspersus 

 north of Texas. 



Thryomanes bewicki bairdi. Baird Wren. — A not uncommon summer 

 resident in the pinon and cedar country of western Colorado. The north- 

 ernmost record for the State is Elk Springs, on the pinon divide eight miles 

 south of Lily, Routt County, where one was seen September 11, 1906. 

 Two others were noted and one collected southwest of Rangely, Rio Blanco 

 County, on September 17. 



Thryomanes bewicki cryptus. Texan Wren. — A Bewick Wren was 

 seen among the cedars on the south rim of Shell Rock Canon, near Gaume's 

 Ranch, Baca County, November 27, 1907. Though the specimen was not 

 secured, it undoubtedly belonged to this recently separated plains race, 

 rather than to bairdi of the mountain region, and is thus the first Colorado 

 record for cryptus. 



Cistothorus stellaris. Short-billed Marsh Wren. — One shot October 

 23, 1907, in a rank growth of marsh grass on the Medano Springs Ranch, 

 15 miles northeast of Mosca, is not only the first record for stellaris in the 

 San Luis Valley, and west of the mountains, but also for the; State. An- 

 other individual was seen in a neighboring tule marsh the following day, 

 in company with a large number of tule wrens. Although the San Luis 

 Valley is far removed from the known range of stellaris, it seems not un- 

 likely that thorough work in the tule marshes lying along the west base of 

 the Sangre de Cristo Range may reveal it as an occasional summer resident. 



Sitta pygmaea. Pygmy Nuthatch. — Noted July 14, 1907, among the 

 yellow pines at the head of Dominguez Creek, on the northern end of the 

 Uncompahgre Plateau, — altitude about 8000 feet. The first Mesa County 

 record for pygmcea. 



Bseolophus inornatus griseus. Gray Titmouse. — At a number of points 

 in the Upper Sonoran zone of western Colorado in 1906-07, chiefly below 

 7000 feet. North to the Escalante Hills of Routt County, where common 

 September 4 to 8, 1906 — a specimen being taken September 4. 



Psaltriparus plumbeus. Lead-colored Bush-Tit. — The following lo- 

 calities indicate a wide distribution in the cedar and pinon country of 

 western and southwestern Colorado: Escalante Hills, flock of 30 near 

 Douglas Spring, September 4, 1906, two collected; Coventry, small flock, 

 July, 1907; Mesa Verde, 25 miles southwest of Mancos, small flock, June 

 14, 1907, at 7000 feet; Arboles, small flock, June 8, 1907.
