You can hear the harmony. No two wolves will howl on the same note. If two do start to howl on the same note, one or both will change to a different note. No one knows why they do this, but they do. When the wolves return from a hunt, the wolves that stayed behind will rush to greet them and many times a round of howling breaks out.
Wolves are very social animals and form strong bonds between other members of the pack.
THEY LIKE TO Wolves like to howl. While resting, a single wolf may start howling. The next thing you know, every wolf in the place is howling up a storm. When wolves howl, they do not always standup and raise their heads. Many times wolves will just lay on the ground and howl.
