About Sherman's Fox Squirrel (Sciurus niger shermani)
As noted by iNat user severnus: "The non-white venter means this is S. n. shermani, which has little genetic support and ought to be lumped with S. n. niger. Until that's done, and while shermani is listed here as a valid ssp, this is what it might be identified as. It can always be left at species level too."
