I was about 50 feet from this coyote at Yellowstone National Park when this one let out a sound that is still ringing in my ears . I just wish I was recording the sound. I don’t think the coyote knew I was so close.
“Howling is a basic communication behavior in coyotes,” says Gary San Julian, a Penn State University professor of wildlife resources. “It has several functions. One is to call the pack—really a family group—back together again after a period of individual hunting. A second reason that coyotes howl is to advertise their presence to other packs, essentially warning those other family groups against trespassing across territorial boundaries.”
