1937 Primitive Area, S.C.Berkeley, Cal. Oct.10, Cooper Hawk seen perched on fence post about 50 yards north of creek at east fence. It was preening its feathers when first seen. When I whistled it flew west into the area and disappeared over the hill. Spotted Towhee and wren-fit seen near creek at this spot. Flicker heard on hill to the south. Stellar Jay heard west in creek bed. Tit 2:25 I heard a Calif. Thresher on the slope just south of the creek that is covered with poison oak & prunus. I observed a large adult Weatume about five feet from its nest going through the poison oak toward the nest. The nest is located just 30 ft. north of the large Quercus californius about 75 yds. west of the east fence. The nest is a small one built around the base of an fallen old oak that has had its heart burnt out. While writing this two flickers lit in the oak overhead - after flying around for several moments after each other with much caw & flapping of wings. There are two Stellar Jays in the far side of the tree tapping on the branches with their bills.
