Sept. 10. 1 mi. N Clayton, Contra Costa Co., Calif. An unidentified sparrow
was flying a foot or so above the stubble in this field. The
sparrow dropped to the ground and the hawk appeared to
turn through 90° of arc to its own left in dropping to the
ground where the sparrow stopped. The hawk flew up into
an oak tree, apparently carrying bird in one foot (I had
no binoculars). I wasn't able to follow subsequent
events. Four Acorn-crested Woodpeckers in this oak.
Sept. 21. En route from Berkeley to Benton, Mono Co., Calif. I left the
campus about 1:10 pm in my Ford accompanied by Richard F Johnston.
We drove via Sacramento and Placerville over Echo Pass and Spooner
Summit (dusk). Thence south on Hwy 395 through Gardnerville and
Reevining. We turned E on Calif. Hwy 120 and drove toward
Benton. Several times the car flushed birds which I think were
Poorwills from the roadside. The headlights gave us a glimpse
of one of these birds fluttering with rapid wingbeats almost
hovering in one place. We ran into a Black-tailed Jackrabbit
which may have been blinded by headlights. At midnight we arrived at
a locality which I had visited on June, 1950.
Sept 22. 3½ mi. S and 3½ mi. W Benton, ± 7000 ft, Mono Co., Calif.
During early morning hours, I heard call of Horned Owl
repeated several times. Our camp was situated at the
mouth of a narrow canyon which was at the base of a gentle talus
slope which extended downward into a valley whose long axis lay
in a N-S direction. The pinyons here were rather scattered and
the Benton Range lay to the east.
ranged to 25 feet in height. Higher on the rocky slopes, they were
18-20 ft for most part. Artemisia Tridentata was prominent
in the shrub-layer, Purshia and Ephedra being conspicuous, however,
