The feisty Vancouver Island Marmot is Canada's most endangered mammal with only an estimated 30 living in the wild in 2003. However, institutions like the Calgary and Toronto Zoos launched aggressive breeding and release programs that have since bolstered the wild population to 200 or more. These pups were born at the Calgary Zoo on June 30th and the Toronto Zoo just welcomed a litter this week!
