The Sierra Nevada red fox is an endangered species living solely in the Golden state and with less than 100 individuals living in the wild, according to the California Department of Fish and Wildlife.

Last winter, he set one of his cameras out on a ledge in Lassen Volcano National Park—one of the animal's last strongholds.

Red fox kits are born with gray fur and blue eyes. When red foxes (Vulpes vulpes) are born, the melanin in their cells is not fully developed, resulting a darker coats and light eyes.

A rare red fox is clinging to life in Washington State, up in the Cascade Mountains. It’s smaller than its lowland cousins, its feet are furrier, and it primarily eats pocket gophers.

Red foxes weigh nine to 12 pounds, about the same as a cat; less common gray foxes, around eight pounds. Grays have a distinctive black stripe on their tails.

Randy Robbins, a California-based wildlife photographer, said his camera captured rare footage of the "highly threatened" Sierra Nevada Red Fox.
