Mayhew 1961 Journal 14. Mar. 18 UCR campus, Riverside Ca., Calif. This morning the field zoology class had a campus trip. We looked for birds primarily - at least during the first half of the trip. Then lizards began to get active. We caught a total of 35 lizards of 3 species, as follows: 9 Sceloporus occidentalis 6 Uta stansburiana 20 Cnemidophorus hyperythrus This was the first time I had ever moosed a C. hyperythrus. They were extremely abundant on the slopes containing Encelia farinosa. As this is the driest year on record for Riverside to date (2.49") no grass has come up & Encelia hasn't leafed out. Consequently, these animals don't have the cover to protect them that they normally do during their active periods. Thus, they were relatively easy to capture. They seem to refuse to go into a hole, but keep moving about on the surface. None of them were seen after 1310 until we quit looking at 1335. They seemed to be much more abundant than Uta stansburiana in that habitat, a total of 28 species of animals were seen on this trip, which lasted from 0820 to 1340. Very few animals were still active when we quit for the day.
