"Scientists speculate that wolves howl for many reasons. In addition to the sheer joy of a community singalong, they howl to communicate with neighboring packs, to establish dominance over their own hunting range, and to inhibit trespassing by hostile wolves. They often howl immediately before a hunt and sometimes communicate with each other when departed during a long chase. Dispersing loner wolves howl to attract a mate, and packs recently howl during the breeding season." ~ Helen Thayer, Three Among Wolves
As of April 2015, 3,600 wolves have been killed in only six states. In 1970s they were on the brink of extinction. In 2016, They are a species still struggling to survive. Only 3 wolves remain on isle Royal and scientist suspect there will be none left after this winter. Stop the slaughter.
