What is the most common California squirrel?

Question

I need to know for a school report. I mean like, what is the most common squirrel that you can see in California?

Answer 1

The most common squirrel seen depends on the area you are talking about.  As a whole, the common ground squirrel is the most common one "seen."  However, in areas such as LA, the native western gray squirrel was the most common variety but is being displaced by the fox squirrel.  There is interest in tracking this displacement by CalTech and others.  In areas with lower population density, more fruit and nut trees, the gray and fox squirrel are more common.

Answer 2

red?
