is probably 47-81430. This location is a good
300 ft., and on other side of the 3 story lodge,
from their streamside territory of late June.
Aug. 15 N. side L Van Norden, 6800ft, Placer-Nevada los, Calif
Becoming commoner - associating with flocks
of Chipping Sparrows; many juvenals included.
Foraging of these flocks is done on the now dry
dusty ground under sparse lodgepole pines.
Aug. 16 near Sugar Bowl Lodge, 7000ft [see p. 1] - Observations
by Audubon campers Bud & Eleanor Hoover of the
pair (banded) at nest discovered on the 14th are
attached to back of this page. One of the 4
young (according to those observers) is now lying dead
on ground a few feet from the nest. The other

clover ski slope at foot of lift, where

are surrounded by what is apparently ideal
Junco & Chipping Sparrow habitat at this
season: dry, sparsely herb-covered ground
under not too dense lodgepole pines. July
100 Juncoos
were seen in 1 hr. 25 min. spent (motor over ½
mi. travelled) in such area at Ice Lakes on Aug. 24,
