Amold 1937 Primitive Area, Strawberry Canyon Berkeley, Calif. Oct. 10, fence on trail "A." Saved as specimens p.n. Creek Trail A. Dung col g - Species unknown - saved for exam. Two Wren-tits heard from brush on north slope of canyon (South side of Monument hill. Another heard from scattered brush and grass just west of small canyon on south side of Monument Hill. - Vegetation and section maps very necessary for plotting exact spots of birds and features. Field glasses will be very necessary. While walking along trail I heard a commotion in willow thicket in bottom of creek. On freezing I detected a Cooper Hawk on the ground about 20 feet below me. I gave its peculiar click-call when I threw a rock into the thicket and then flew from the ground into the depth of the thicket. Perhaps it has something in its talons not as yet I have not seen. As I stand here it is making a commotion in the bottom of the thicket but I can not see it. Every time I throw rocks it goes crashing through the brush.
