Foxes and coyotes are very apt to dig into the ground where they detect the presence of a mole. In the pictured scene, the digging of a coyote was evident from the disturbed snow and earth and the abundance of coyote tracks. Two excavated holes led directly into an underground tunnel.
While many sources state that moles are part of a coyote’s diet, there are many instances, including the one pictured, where the mole (hairy-tailed) is left untouched after being unearthed by a coyote. Unlike northern short-tailed shrews, moles are not toxic and one wonders what occasionally prevents a coyote from consuming its prey.
