OCT., 1899.] BIRDS. 131 
120. Thryomanes bewicki spilurus. Vigors Wren. 
Seen at Sisson, but not on the mountain. Recorded by C. H. Town- 
send from ‘the base of Shasta.” 
121, Troglodytes aédon parkmani. Parkman Wren. 
Rare on the mountain. One collected near Squaw Creek Camp (alt. 
6,750 feet) August i8 by R. T. Fisher, and one in Mud Creek Canyon 
(alt. 6,780 feet) Angust 9 by W. H. Osgood. More common at Sisson, 
where it was observed by Miss Merriam the middle of July. C. H. 
Towrsend records it as abundant in midsummer “among the piled-up 
logs of a certain clearing in the forest at the base of Mount Shasta.” 
The bird seems to be intermediate between parkmani and aztecus. 
122. Cistothorus palustris paludicola. Tule Wren. 
At Big Spring, in Shasta Valley, W. H. Osgood found these wrens 
common September 17 to 20. 
[The western winter wren (Anorthura hiemalis pacifica) was not 
observed by us, but was found by C. H. Townsend in the mossy canyons 
of the lower McCloud. It doubtless occurs in the upper canyon of the 
Sacramento near Sisson, and quite possibly in other suitable places 
about the mountain. ] 
123. Certhia familiaris occidentalis. Western Brown Creeper. 
Not common, but seen now and then in the alpine hemlocks on Squaw 
Creek and in the Shasta firs, 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 place 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 seen at Squaw Creek Camp from time to time in August, once 
or twice in the mixed tlocks of chickadees and warblers. 
125. Sitta canadensis. Red-breasted Nuthatch. 
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. 
126. Sitta pygmea. Pigmy Nuthatch. 
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 south- 
west end of Shasta Valley, not far from Edgewood, Osgood saw several 
in the pines September 20.
