Squirrel Facts


I have been receiving number of emails from visitors doing research on squirrel and they are asking me to put details of every squirrel species on one page so that they can get them all at one place and compare them convenient way. And here are the Facts about all species of Squirrels. I have tried to categorize various facts about squirrels in categories like their scientific name, where they can be found, their description, habitat, Squirrel diet and their reproduction cycle.

You can click on the specific Squirrel species to get DETAILED information (click on the first column in blue). Still if you need more details or you want me to put some more content, please email me. Feedbacks/Suggestions are highly appreciable.
