Why are the Wolves Howling?

This time of year our wolf pack is pretty vocal, but especially when the tornado sirens go off the first Tuesday of each month! Scientists believe that canines like wolves, coyotes, and domestic dogs howl along with sirens because they think it's another animal. The sound doesn't hurt their ears, they're just protecting their territory!
