A Coyote, sporting a gorgeous winter coat in Yellowstone National Park a couple of weeks ago, is on the alert, mousing for its next meal. Voles, or whatever it was hunting in the thick grasses, could conceal themselves pretty well so this Coyote had to be very attentive. It pricked its ears to listen for telltale rustling that would point out the location of the voles. We watched it pounce a couple of times but it came up with nothing. Hopefully, it was successful after we left.
