Cogswell 1950 Junco oreganus 5 (Am now banding on R. leg) Aug 14 (could) band on L. leg, a featherless (the healed) fore- feal. Her mate is also banded on the L. leg . ? 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 3 were still in the nest on Aug. 18. Aug. 20 - 26 Numbers greatly increased in some areas, but influx Here, only on the borders of the flattish herb- clover ski slope at foot of lift, where they mix with Cassin finch & Chipping Sparrows. See Lakes (see June 24) & Lake Van Norden, however, 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,
