On our walk around Prince's Island today, we stopped to give one of our squirrel friends some fresh peanuts. This one was very adept at taking two at a time. Despite it's name, Eastern Grey squirrels are not always grey. Some are grey, some are black and some are cinnamon. The Eastern Grey Squirrel is not native to Calgary. According to one source (weaslehead.org), Tom Baines, then director of the Calgary Zoo, obtained seven squirrels on a visit to Ontario in 1938, for display purposes. The squirrels soon multiplied, and, as an experiment, six pairs were released beside the Elbow River in the Elbow Park area of Calgary.
City life seems to suit these squirrels, mostly because there are few natural enemies here (hawks, Great Horned Owls, coyotes and weasels). The automobile is their biggest predator. Eastern Grey Squirrels do not hibernate. During stormy weather, they stay in their shelters, perhaps eating some food from their cache.
