"Welcome to the Be Bear Aware home page. North America is home to three different species of bears, some say actually four. In this site you will learn what makes each species uniquely different. You will learn how bear habitat varies across North America.
"This web site places special emphasis on keeping bears wild...."

A tip of the hat to irish_brigid, on Twitter, for the heads-up on this.
