Rotford, Rolf 1974 Journal 10 Dec. 20k E, 1 mi. S Tecate, Baja California del Norte, Mexico ~1000 m. which had been gnawed off, apparently with 3 or 4 bites. We found several Neotoma nests and figured they had done most of the chewing. None of the scats looked like Microtus sign. Rabbit pellets and woodrat scats were abundant. We talked to a local farmer who had just put in a well and found out from him that the water table was about 40 ft. down. We went back toward the highway, then went east about 2 1/2 miles along a dirt road which ran parallel to the highway. Then we turned north and went another couple miles, passing a farm with goats, pigs, cattle, horses, and a very open field. We set up camp just north of the fenced field and started setting out traps at about 1530. We set out over a hundred large folding Sherman's, 8 small Tomahawks, a couple dozen gopher traps. There were quite a few holes about 3 cm. in diam., some apparent woodrat nests in the rocks, and some gopher mounds. The habitat was similar to the place a couple miles west - brush with sparse grass, large boulders in spots, a few scattered oaks. The temp. at 2000 hrs was 26 deg F and the sky was clear. The day had been clear, wind light but increasing at dusk. We saw a dark brown bobcat and Dr. Lidicker saw a coyote from a distance. Also red-tailed hawks, scrub jays, Calif. quail, western kingbird, bushtit, Lawrence's goldfinch, red-shafted flicker.
