Watched mice from tower in Orinda pasture at 7:15 p.m. Cloudy but calm, saw numerous meisters, no fights or squeaking. Have seen no mice there for several weeks. Horned owls always there evenings. Tonight, even at late dusk, two red-tails circling high and screeching and diving at each other. Sept. 7 Picked up scats in Tilden. Saw several meisters, many lizards (Geckos) both large and tiny, two red-tails one of which caught a mouse and ate it while I watched, one sparrow hawk, one large gopher snake, large corey of grain, and two cats on my area (one white, grey, red tan; other grey striped). Also smelled skunks. May have failed to mention squashed striped skunk on road along north edge of my area about 3 weeks ago. Covered about half of Tilden this collection. Sept. 12 about 1/2 inch grain. Sept. 19 Picked up scats in Tilden at 4 p.m.. Saw lots of mice and small lizards, 2 red-tails, 1 wood mouse. Saw cats.

Watched from Orinda tower at 7:15 p.m. Saw only
