Detailed Description

This American black bear and cub duo was seen simply investigating a tortoise burrow, and although it is surprising to see a black bear so low in elevation, it isn't impossible. The study site, Mesa, sits at the intersection of multiple ecosystems (Sonoran Desert, Mojave Desert, montane, and coastal sage scrub). Therefore, the bears could have come down from the montane area. 

Infrastructure associated with wind energy facilities can influence the behavior of animal predators and their prey, according to a recent study by University of California – Davis and the USGS.

Motion-sensor cameras were placed facing the entrances of 46 active desert tortoise burrows in a wind energy facility near Palm Springs, California. Recordings showed that visits to burrows from four predators increased closer to dirt roads, and decreased closer to wind turbines.
