Chamaea fasciata henshawi Ridgway. Pallid Wren-tit. 
This bird was a characteristic inhabitant of the Upper Sono- 
ran brush belt on the south slope of the mountains. It was noted 
throughout the chaparral slopes on the north side of the upper 
Santa Ana from Clarke’s ranch, past Seven Oaks, clear to the 
south face of Sugarloaf, 7000 feet, across which extends a tongue 
of the Upper Sonoran zone. A pair was also seen in the willow 
thickets at Bluff lake, July 23, 1905; these were full-grown juv- 
enals and had doubtless wandered over the short distance from 
the brush on the south side of the mountain. The species was 
seen on the north base of Sugarloaf, 7500 feet altitude, among 
the service-berry bushes, on August 19 to 23; and it was fairly 
common at Cactus Flat earlier in the same month. Four speci- 
mens were taken. 
Psaltriparus minimus minimus (Townsend). 
California Bushtit. 
The California bushtit in the nesting season was strictly con- 
fined to the serub oak belt of the Upper Sonoran zone. It was 
common in this belt near Seven Oaks, 5000 feet, where a nest 
was found July 12, 1905, with young. July 3 we saw a flock on 
the south face of Sugarloaf, 6500 feet. At the north base of 
Sugarloaf, 7500 feet, flocks were seen August 20, 1905; and it was 
common at Cactus Flat August 15 to 17. The last of July and 
the first of August, 1906, large companies of bushtits, families of 
young and adults, appeared along the Santa Ana as high as Fish 
creek and South Fork. One flock was seen July 30 among the 
black-oaks and pines above South Fork, at an elevation of fully 
7500 feet. These latter records doubtless pertain to birds which 
had wandered up temporarily during the season of plentiful 
insect life, from much lower levels. None were seen in the same 
place during June. Four examples were taken. 
Regulus satrapa olivaceus Baird. 
Western Golden-crowned Kinglet. 
This bird was met with but once, August 19, 1907, near our 
Cedar Cabin camp on the upper Santa Ana, altitude 5500 feet. 
I was serutinizing a mixed company of chickadees, nuthatches,
