OCT., 1809.] BIRDS. 131 



120. Thryomanes bewicki spilurus. Vigors Wren. 



Seen at Sisson, bnt not on the mountain, llecorded by 0. H. To\vn- 

 seiid from "the base of Sliasta." 



llil. Troglodytes aedon parkmani. Parkman Wren. 



Kare on the mountain. One collected near Squaw Creek Camp (alt. 

 C>,1~)0 feet) August 18 by R. T. Fisher, and one in Mini Creek Canyon 

 (alt. 0,780 feet) August 9 by W. H. Osgood. More common at Sisson, 

 where it was observed by Miss Merriam the middle of July. C. H. 

 TowL'send records it as abundant in midsummer "among the ])iled-up 

 logs of a certain clearing in the forest at the base of Mount Shasta." 

 The bird seems to be intermediate between parlmani and aztecus. 



lUL'. Cistothorus palustris paludicola. Tule Wren. 



At Big Spring, in Shasta Valley, W. II. Osgood found these wrens 

 common September 17 to 20. 



[The western winter wren [Anortliura hiemalis paciiica) was not 

 observed by us, but was fouiul by C. H. Townsend in the mossy canyons 

 of the lower McClond. It doubtless occurs in the upper canyon of the 

 Sacramento near Sisson, and quite possibly in other suitable places 

 about the mountain.] 



12.'). Certhia familiaris occidentalis. Western Brown Creeper. 



Not common, but seen now and then in the alpine henjlocivS on Squaw 

 Creek and in the Shasta tirs, lower down. The earliest record is July 

 24 (J. H. S.); the latest, September 15 (C. H. M.). At Wagon Camp 

 John H. Sage shot one and saw another July 27; and Miss Merriam 

 saw one in the same ])lace August 1, one at Squaw Creek August 30, 

 and two at Sisson September 3. 



124. Sitta carolinensis aculeata. Slender-billed Nuthatch. 



Not common on the mountain, and only moderately so at Sisson. A 

 few were vseeu at Squaw Creek Camp from time to time in August, once 

 or twice in the mixed tlocks of chickadees and warblers. 



125. Sitta canadensis. Ued-breasted Nutliatch. 



Common from the lower edge of the Shasta fir belt up to timberline; 

 and from the time of our arrival, the middle of July, until our depart- 

 ure, the latter part of September. In September it was often seen in 

 mixed flocks with mountain chickadees and Audubon warblers. 



120. Sitta pygmsea. Pigmy Xutiiatch. 



In the ponderosa pines near Sisson, W. H. Osgood saw pigmy nut- 

 hatches July 13, and I saw a small flock September 30. At the sonth- 

 west end of Shasta Valley, not far from Edgewood, Osgood saw several 

 in the pines September 20.
