July 24 near Sugar Bowl Lodge, 7000 ft. 1.2 mi. SSW Donner Pass,
25 Placeto, Calif - 3(201)
31 seen in denser red fir & silver
lodgepole pine forest areas, or flying over
the open slopes between patches of forest.
one ? (on 24 th) was seen nibbling at young needles
of short red firs. 1 ad. ? seen on 31 st, no
song heard on these dates, however.
Aug. 2 Following up a whistled call - note unknown
to me, I found it to be given by an grey-plumaged
Bird Grosbeak with full length tail (= grown young).
It was perched in upper branches of a clump
of a few red firs & pines on partly cleared N
slope of Dursey Mtn., giving the "whreeee" call
every few seconds. Soon after this bird was
located, an adult ? flew into an adjacent
tree, calling its normal "tu-will-to-wit", and
the young (?) bird flew to it immediately and
was fed. Then both flew off up the steep
mountainslope to larger forest area beyond
an alder filled draw.
Other individuals seen & heard in vicinity of lodge.
Aug. 7 (p.m.) 1 pair seen at close range as they foraged
on lower branches of young firs & pines in dense
forest, and for few moments) on the ground
as well. Their only call notes were soft whisperings.
Aug. 11 7150 ft., ½ mi. S Donner Pass, Placer Co., Calif. - 1 seen in
tree tops of mountain slope above Nest site (see June 29).
It was giving the same note as young one of Aug. 2.
