around the margin of Dry lake July 15, 1906. In Bear valley 
the last of July large flocks of full-grown young of this species 
were feeding along the lake shore. Only one individual was 
seen in the pimon belt. This was an immature taken at a spring 
a little below Cactus Flat, August 9, 1905. At Saragossa springs, 
northwest of Gold mountain, and through Holcomb valley, Aug- 
ust 26, chipping sparrows were noted, especially near watering 
places. Twenty-six specimens in all were taken. 
It seems strange that we have to call this in the San Bernar- 
dino mountains a strictly Transition and Boreal species, when 
it is at the same time a common breeding species in the gardens 
of many of the valley towns of southern California, Upper and 
perhaps also Lower Sonoran. 
Spizella breweri Cassin. Brewer Sparrow. 
This was a characteristic and abundant bird in the Arte- 
misia belt on the desert slope of the mountains. In the vicinity 
of Doble, 7000 feet altitude, and at Cactus Flat, 6000 feet, the 
species fairly swarmed in August, especially about the few 
springs. As early as August 4, birds-of-the-year were in com- 
plete winter plumage. They were also met with in small num- 
bers at Cushenbury springs, at the desert base of the mountains, 
August 10 to 14, 1905, and a few at Saragossa springs, north- 
west of Gold mountain, August 26. On the sage flat at the north 
base of Sugarloaf a few were noticed August 21. On the Pacifie 
side of the mountains several full-grown juvenals were met with 
in a sage flat at the lower end of Big Meadows, 6700 feet altitude, 
on July 4. A small company of young was found on a mountain 
side near the South Fork, 7500 feet, June 30. In the brush belt 
at Seven Oaks full-fledged juvenals were common July 7 to 10. 
The species appeared the first of August, 1906, along the upper 
Santa Ana, between the mouths of Lost and Fish creeks, and a 
bird-of-the-year in full first winter plumage was taken on the 
third of that month. In the latter four localities I concluded ° 
that the birds had made their appearance after the breeding 
season, moving over the short distance from the sage belt on the 
north side of the divide, at the head of the Santa Ana. Sixty- 
eight specimens were secured.
