12 Journal Jan. 29 3 mi. NW Rabbit Peak area, Riverside Co., Calif. Titmice and one Wren-tit. About one pm I began to descend the south-facing slope of the same canyon starting from the upper basin at about 4000 ft. At about 3900 ft. near the base of a prominent marble hogback I collected a Citellus leucurus, which was sitting in a Ceanothus bush. From this point until I reached the floor of the canyon at the 3700-foot level I saw no birds. When I did reach the moist spot at 3700 feet a small flock of Juncos came to the floor from above and pecked at the sandy floor. A Bewick Wren was heard here. Down at the 3600-foot level on the way out I saw two Ruby-crowned Kinglets. After I left the canyon and headed north over low ridges I heard a Raven and what sounded like a hummingbird. Dr. Miller worked the top part of the south slope of the same canyon and then dropped to the west into the north- south canyon that we ascended Jan. 27 & that enters Martinez Canyon at the 1500 foot level a short distance above our camp. He collected Titmice & Bush-tits at the upper level (about 5, 000 feet) and saw there a Nuttall Woodpecker and a White-breasted Nuthatch. He collected a Brown Towhee and several Hyla arancolor in the canyon at the 2500-foot level. The weather was calm & clear all morning but clouds over in the P.H.
