123 Red-breasted Nuthatch R.E. Johnson 1967 March 4 Strawberry Canyon, Alameda Co., Calif. Warm sunny, oak-grassland south facing slope with patches of brush & patches of pines. Two (pair) birds in open stand of Italian (apparent or) Stone Pine. One bird has more red on upper breast than other (apparent ?). The ? pecks at hole in dead Tree (pine), perhaps widening it for nest cavity or perhaps looking for food or part of courting procedure. The ? flies up & feeds ? then flies off. She continues to peck. Later leaves & returns again. Both feed in a live pine, searching main trunk at 10+ ft. up & also around cones on branches. [? stood facing sideways & partly downward while working on hole]. Bush-tits also present, one Nuthatch gave brief chase & bush-tit flew short distance. 11:30am - 12:00 noon
