I don't guess we have that "red" squirrel because our "reds" (aka fox) are bigger than greys.
I googled it and it seems there is an invasive eurasian "red squirrel" somewhere in the new world. Never seen one here, only native reds.
Grey or "cat" squirrel...
Red or "fox" squirrel
I can't seem to find where eurasian reds are in the US. Is THIS what you all are calling "red" squirrel? I've never seen one, new to me.
I'm also confused because I find a link to an "American Red Squirrel" and come up with a pic of a grey squirrel or at least what looks to ME like a grey squirrel, belly is white, not red.
I learned about Red and Grey squirrel in "Introduction to Wildlife and Fisheries Management" at Texas A&M as a sophomore before I switched my option to fisheries management. What my grandpa had always called a "fox squirrel", the prof, Doctor Englis, called a "Red" and what my grandpa always called a "cat", doctor Englis called a GREY squirrel. Maybe I should have listened more in class, but there's two species in Texas...red/grey, well, I've killed both. LOL!
Oh well, what the heck, I just shoot 'em and eat 'em, ain't going to get worked up over semantics.
