FUN FACTS
- Vancouver Island Marmots are one of the rarest mammals in North America, with a population that has fluctuated dramatically over the years
- They are also known for their unique vocalizations, which include whistles and chirps used for communication within their colonies.|These marmots hibernate for about 7-8 months of the year, during which they rely on fat reserves accumulated during the summer
- Their hibernation behavior is crucial for survival in the harsh alpine environment where they live
