Vancouver Island Marmots

The main reason behind our Canada Day long weekend getaway (besides to escape Vancouver after 5 months of quarantine) was to spot and photograph the Vancouver Island Marmot. A large ground squirrel, this particular subspecies has a distinctive chocolatey coat and measures about 65cm or so in length.

Living high up in alpine meadows, they hibernate from mid-September to early May in burrows below the frost line. In the few months a year they are awake, they graze on sedges and grasses for a few hours daily and then rest in the sun the rest of the time.

We took several hikes searching for them and eventually managed to spot the one below:
With a little patient creeping forward and a telephoto lens, we were able to get several nice photographs of this individual (#150 judging from the ear tag). Of the 15 species of marmots in the world, these are among the most endangered mammals in the world, due to their concentration entirely on Vancouver Island and several years of over predation (on the one hand, this is a species that we didn't actually hunt or directly wipe out for once, on the other hand, the over predation was doubtless a result of habitat destruction and/or impact on primary prey stocks that WAS a result of human activity.)

The recorded population plunged to as few as 30 animals in 2004 but they are currently a success story, with annual counts of 190-250 in the last few years, due to increased conservation efforts and breeding programs.
Mount Washington is not only one of the primary colonies to these animals, it is also a safe haven where young animals are given a "training year" of living in the wild before potentially being captured and relocated to a more remote area.

The popularity of Mount Washington as a downhill biking destination means that traditional marmot predators such as cougars, wolves, and golden eagles are driven away by steady human presence. This gives fresh releases an opportunity to get the hang of living in the wild without undue risk but still makes it possible to spread the population over several colonies to prevent unexpected problems from wiping the species out.
A higher concentration meant we were able to see a second marmot from the chair lift on the way down on a subsequent hike. This one was a less poised individual, huddle at the side of a bike trail and sitting on his own tail.
