Coyotes are not finicky and will hunt prey both large and small, from elk to insects and everything in between. This adaptability helps the coyote make its home in both remote regions and near urban areas.

Image description: The Pacific Fisher.

Fishers have long, slender bodies with muscular, short legs similar to their cousins — weasel, mink, marten, and otter. Their thick, grayish-brown to brownish-black glossy fur tends to be darker on females. White-tipped hairs on the older fisher give a grizzled appearance. This forest carnivore has strong claws for climbing and a long, bushy, black, tapered tail. The also have five toes on each foot and semi-retractable claws which contribute to their ability to climb trees. Males average 4-12 pounds, about twice the size of females.
