I enjoy watching the squirrels in our yard. They chase each other up and down trees, jump from limb to limb and have a quirky manner about them that's just funny.
But, did you know these industrious little rodents are not native to California? From my Internet research, it looks like our squirrels are Fox Squirrels and were introduced here from the east.
Fox Squirrels liked it in southern California -- nice weather, year 'round food, lots of neighborhood trees, no natural enemies. Kind of squirrel heaven.
These squirrels seem to much a natural part of the environment in Pasadena, it is strange to think they're really an introduced species and that there was a time, not so far away, when they didn't live here at all.
