Arnold 1937 Primitive Area, S.C., Berkeley Calif. Oct. 10, A vireo (Prob. Hutton) was perched in the top of the oak just above my head. 5:30 P.M. Junco seen on brushy slope just north of orch. - Much evidence of mouse digging on this side hill. Earth of gravelly texture probably good for Trogognathus Dung 622 More feces found on trail in north side of canyon - presented for "identification". Quite a bit of gopher sign and in one place some diggings that could have easily been ground squirrel was seen on the top of Monument Hill. A flock of 8 Valley Quail were seen in the corner near the double fence closest to the botanical garden. On the whole the most interesting and probably the most significant feature today was the abundance of Cooper Hawks. From my scanty observations thus far I would say that those Cooper hawk probably nested in this area and some of those seen are young of the year (as told by plumage color)
