The Virginia opossum is the only marsupial found in North America. These furry creatures are also one of the oldest mammals on the planet, dating to at least 70 million years ago! Often wrongly mistaken for rodents, the Virginia opossums do not possess hair on their large ears and their tails, with the exception of its base. This makes these hairless areas a common site for frostbite! Speaking of bites, though opossums are known to fake death, hence, the saying “playing possum” in response to threats, not all are docile, for some may react aggressively to defend themselves! These animals are cunning opportunists that have a taste for plants, animals and even carrion! You might even see one digging up your garbage bins at night. #Canada150 #Biodiversity150

This year, Ontario’s ever so fluctuating winter weather has everyone eagerly looking forward to Groundhog Day. As the groundhog emerges from their burrows, citizens of Ontario are on the edge of their seats as they wait to see if the groundhog sees its shadow, indicating the early or late arrival of spring. Vancouver Island Marmots (Marmota vancouverensis) are one of only five endemic mammals to Canada and can only be found living in the high mountains of Vancouver Island. They are closely related to groundhogs, classifying under the same Genus, Marmota. It is believed the marmots originated from the mainland during a glacial period where water levels dropped creating a land bridge. This allowed them to cross over to what is now Vancouver Island and evolve separately from other marmots. Their habitat consists of subalpine and alpine meadows and they are herbivores which feed upon over 50 different species of grasses, flowers and herbs. Much like the groundhog, they live underground in burrows close to their food source and to hide from potential predators.
Vancouver Island Marmots are the most endangered mammal in Canada with their population dropping to 30 individuals in 2003. The Toronto Zoo started a recovery program in 1997, in hopes to restore the population of the marmots. So far the captive breeding program has successfully bred 167 litters and 556 pups and are working towards restoring and reintroducing their population.
