J Davis 1950 Red's Meadow, 7500 feet, Sierra Nat'l Forest, Madera Co., Calif. Aug. 29, 1950 - Sept. 9, 1950 Red's Meadow. My impression is that a large and a small individual were seen on diffe- rent occasions, possibly at mated pair. At any rate, a weasel (or weasels) is now apparently established in exactly the same territory which shot a pair (???) in 1948. In 1949, no weasel were seen in this territory. The birds reacted only moderately to the presence of the weasel. In 1948, when the birds were breeding, the mobbing and calling was terrific. Citellus lateralis. Adults + young were present on all the meadows visited, although most abundant at Soda Springs Meadow where about 20 were counted within a circle of 10 yards radius. Citellus lateralis. Common. At least 6 different individuals in camp. Two young, four adult. Citations of. Very common. Seven in camp at one time. Tamiasciurus douglasii. Very common. Young and adults seen and heard constantly at Red's Meadow and Agnew Meadow. Cone-gathering acti- vity high. This species has been inconspicuous on our three previous visits to Red's Meadow. Thomomys sp. Gopher workings seen at Agnew Meadow.
