Blunt-nosed leopard lizards (Gambelia sila) are generally active from mid-spring to early fall, entering a period of brumation during the winter months. The California Department of Fish and Wildlife survey methods are designed around the optimum times for detection: April 15 to July 15 (adults) and August 15 to September 30 (hatchlings). After protocol surveys had been completed with negative results, McCormick Biological, Inc. staff detected a blunt-nosed leopard lizard, possibly young of the year, during site preparation work for a project. To ensure avoidance, we monitored the individual daily as it foraged in nearby habitat. Biologists noted foraging, nightly burrow selection, movements and weather between October 12 and November 22. Adults of this species have been found to be opportunistic foragers, lying in wait for insects and occasionally other lizards. In addition to consuming insects, the individual we observed pursued more lizards than we expected, consuming several over the observation period. Burrow construction and use of existing burrows were both observed. These observations are of value in understanding conservation considerations and habitat use expected of this species. | |||
