The common squirrel - Almost all parts of Canada and the USA have this common rodent in their back yard. They seem to thrive in the city and in the country side. Some people think they are cute and adorable and love to feed them. Others think of them as just a pest to be exterminated. For me I like them, they are a creature of survival, fast learner, quick at adapting and fast on their feet. Yah for the common squirrel.
