Wolf tracks are similar to coyote and dog tracks. They are much larger than those made by coyotes but some dog tracks that are larger than what a wolf makes. Mountain lion tracks are often mistaken for wolf tracks. Howling Wolves howl, bark, whimper, and growl. Wolves have a variety of communication tools including scent marks, vocalization, visual displays, postures and rituals.
Wolves sometimes bark if their den is disturbed of if they are surprised.
The howl of a wolf is described as deep and mournful. The howl is continuous and can last up to 11 seconds. The pitch is constant or, if it varies, does so smoothly. A howling session by one lone wolf lasts about 35 seconds, and the animal will howl several times. When a pack is howling they go on a little longer.
