Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support.

Bat Thermal Video

Imagery from temperature-sensing cameras showing bats in hibernation. This new footage suggests that bats who warm up from hibernation together throughout the winter may be better at surviving white nose syndrome, a disease caused by a cold-loving fungus ravaging insect-eating bat populations in the United States and Canada.

Animal Interactions at Wind Energy Facilities – Gray Fox

There were two documented gray fox visits at the burrows, making them the third most documented predator. Gray foxes are implicated predators of various life stages of desert tortoises, but it is difficult to catch them in the act. In this case, a gray fox approaches a burrow, and thoroughly investigates the burrow mouth. The fox develops an arch in its tail (slight

Animal Interactions at Wind Energy Facilities – Western Spotted Skunk

There was one documented skunk event captured on camera - the least documented predator. Here, a western spotted skunk is thoroughly investigating the burrow of one of the marked female tortoises in the study population. Western spotted skunks are known predators of turtle eggs. The skunk investigated the area within the burrow for a full minute before it appears outside

Animal Interactions at Wind Energy Facilities – Bobcat

In this video, a bobcat approached a desert tortoise (a marked female in the study population) that was sleeping on the apron of her burrow. Bobcats are known predators of various life stages of the desert tortoise. In this case, the bobcat bent down to sniff the tortoise, and then touched its paw to the top of the tortoise's shell. The tortoise then moved into an "all-

Animal Interactions at Wind Energy Facilities – American Black Bear

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

Animal Interactions at Wind Energy Facilities – Coyotes

Coyotes were the second most frequently observed mammalian predator on the trail cameras. Coyotes are considered one of the primary predators of desert tortoises. In this instance, a coyote is passing by a burrow when it suddenly has a change in attention as it is passing by. It then approaches the burrow and sniffs all around the burrow entrance (including the apron and
