KDixon 1950 Journal 44. 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.

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,
