Variegated Squirrel

You may even add Sciurus variegatoides dorsalis.

And yes, now that I think about it, he did have some black on the back.

Well he sure does look like the squirrels in the link. I believe I can label him as a Variegated Squirrel now!

This one might have had some black on the back, could you remember? And I just detected an erratum in my mammal book. I am pretty sure this one is the Sciurus variegatoides dorsalis. But some of the IDs are not correct on the web.

Indeed I think he maybe...did a little searching a white seems fairly common for them...here's one of the links I came across...http://www.gaianicaragua.org/sciurusvariegatoides.html

Yes, I suppose so. Perhaps he's a color morph of a Variegated Squirrel. Thank you :)

He may be a white color morph or albino of a common squirrel.
