132 NORTH AMERICAN FAUNA. [No. 16. 
127, Parus gambeli. Mountain Chickadee. 
Common and widely distributed. In the firs at Wagon Camp they 
were among the commonest birds, and at higher altitudes were seen or 
heard nearly every day. arly on the morning of July 24, after camp- 
ing for the night in the shelter of a narrow fringe of dwarf white-bark 
pines at timberline, on one of the desolate torrent-swept beds of Incon- 
stance Creek, high up on the north side of Shasta, we were saluted by 
a small tlock of these cheerful little birds. In September they helped 
form the mixed flocks, along with Audubon and other warblers, Cavada 
nuthatches, and other small fry so often seen among the Shasta firs and 
alpine hemlocks. At Sisson Miss Merriam saw them about the mid- 
dle of July; they were common there in September, and were noted in 
Shasta Valley by W. H. Osgood September 17 to 20. 
128. Parus rufescens. Chestnut-backed Chickadee. 
Not observed by us, but recorded by C. H. Townsend, who “ obtained 
a single individual at the western base of Mount Shasta on July 14, 
1883.” 
129. Psaltriparus minimus californicus. California Bush-Tit. 
Common along Little Shasta Creek September 18 (W. H. Osgood). 
Seen in the chaparral west of Gazelle, on the west side of Shasta Val- 
ley, August 31 (Vernon Bailey). Townsend found it a common breeder 
near the fish hatchery on the Lower McCloud River. 
130. Regulus satrapa olivaceus. Western Golden-crowned Kinglet. 
Both kinglets are common on Shasta and doubtless breed in the 
Shasta firs of the Canadian zone. The golden-crown was often seen 
and heard at Wagon Camp, where it was collected July 18. It was 
also common just within the lower edge of the ftir forest in Mud Creek 
Canyon July 23, and a couple of miles higher up about the end of the 
month. ©. H. Townsend obtained specimens at timberline in July, 1883. 
131. Regulus calendula. Ruby-crowned Kinglet. 
The ruby-crown was frequently heard by various members of the 
expedition, and at different altitudes, from Wagon Camp in the lower 
edge of the Shasta firs, to timberline, where one was collected by W. H. 
Osgood August 4. In 1883 C. H. Townsend obtained two specimens, 
one at timberline August 15, the other at an elevation of about 6,000 
feet September 2. 
132. Myadestes townsendi. Townsend Solitaire. 
Not an uncommon breeder on the higher slopes of Shasta, where I 
saw SIX during our stay. The lowest of these was at Wagon Camp, in 
the lower edge of the Shasta firs, where one drank at our spring July 31. 
The others were in the Hudsonian zone, and most of them in the alpine 
hemlocks at or near our camp on Squaw Creek, just below timberline.
