Cogswell 1950 Pinicola enucleator 3 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.
