1908] Grinnell—Biota of the San Bernardino Mountains. 93 
Fork canons; up the latter to 8500 feet elevation, June 29, 1905. 
Several pairs were seen on San Bernardino peak, 10,600 feet 
altitude, on July 12, 1905, where they were singing volubly 
among the limber pines. They were abundant on the meadow at 
Bluff lake where they were feeding on grass seed; full-grown 
young were taken there on July 25. A solitary individual was 
taken at a spring on the north side of Baldwin lake August 4, 
1905. Otherwise none were noted on the desert side. Eleven 
skins of this species were secured. 
Passerculus sandwichensis alaudinus (Bonaparte). 
Western Savanna Sparrow. 
At Cushenbury springs, 4000 feet altitude, August 12, 1905, 
an immature specimen in full fall plumage was secured, and 
another seen. These were evidently migrants. 
Chondestes grammacus strigatus (Swainson). 
Western Lark Sparrow. 
This species was met with at Doble, 7000 feet altitude, August 
6, 1905, when a full-grown juvenal was taken, the only one seen. 
It was noted commonly on several dates in June, July, and Aug- 
ust, 1907, on the stubble fields at the mouth of Mill ereek canon. 
Spizella socialis arizonae Coues. Western Chipping Sparrow. 
The western chipping sparrow was a common species from 
the lower limit of the yellow and Jeffrey pines up nearly to 
timber limit on the highest mountains. It was constantly abund- 
ant all along the Santa Ana from Seven Oaks to Big Meadows. 
In June and July the species was noted regularly and in fair 
numbers up the ridges toward San Gorgonio peak. June 18, 
1905, I saw males in full song among the limber pines up to fully 
10,000 feet altitude. Several were met with on the very summit 
of San Bernardino peak, 10,600 feet, July 12, 1905. At Dry 
lake, 9000 feet altitude, June 14, 1906, a nest was found con- 
taining four much incubated eggs. The nest was in bulk and 
structure typical for the species, and was situated fourteen feet 
above the ground in a tuft of needles near the extremity of a 
branch of a tamarack pine. Full-grown young were numerous
