     Howling(吼叫) is a behavior commonly observed among a wolf pack(狼群). As pack animals,
wolves work together to hunt and rely on howling as an important means of communication among
each other. There're different explanations of a wolf's howl and it appears that there may be more to
discover．
     One theory is that wolves howl to bond better together. It's almost as if howling together helps
the pack stay together. Perhaps something similar to people feeling a sense of involvement with each
other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a

a social bond or just a way to reconfirm status (地位) among its members? Why do wolves howl
for sure?
     What is clear, however, is that howling is often used among packmates to locate each other.
Hunting grounds are distant and it happens that wolves may separate from one another at times. When
this happens, howling appears to be an excellent means of gathering.
      Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others
will follow. This is often seen to occur in the morning, as if wolves were doing some sort of "roll call"
where wolves all howl together to report their presence.
