Wolves generally mate for life and typically only the alpha pair will mate in the pack.  Packs can range in size from 2 to 35 members.  Packs with more members feed on larger prey including moose, caribou and other “mega-vertebrates.”  Smaller packs feed on mice, rabbits, deer and similar-sized prey.  Howling is used to communicate with other wolves and can be heard for many miles on a calm night.
