R. J. Raith 1956 Journal January 27 Martinez Canyon, Santa Rosa Mts., Riverside Co., Calit. east-west draw which contained all of the plants named immediately above. We descended the few feet down into this draw and started up a tributary north- south draw which contained a thicker stand of the chaparral species. A short distance up this draw and two scrub jays 300-400 ft higher, Dr. Miller shot a Titmouse, we each went up a side of this draw up toward another east-west divide. The wind was blowing very strongly from the west from this time until we got to camp rendering the location of birds by sight or sound quite difficult. I saw nothing while ascending this slope and heard but could not locate a Titmouse just on the other side. On this other side (on a north slope of the head of an east-west canyon) we ate lunch at about 11:15 AM at an elevation of about 4000 ft. Then we worked upslope toward the south through quite thick chaparral of scrub oak, manzanita, Ceanothus lemonade Berry, and pinyon pine. We heard a Titmouse and were heading toward it when Dr. Miller heard a Wren-tit. After one shot by each of us he finally bagged one with a possibility of another one escaping us. While looking for a possible dead Wren-tit we saw a nest of a Woodrat around the base of a lemonade Berry bush. It consisted of a conical pile of twigs, and many pinyon pine cones were scattered around it. The location of this chaparral slope where the Wren-tit was taken was 3 miles NW
