The Grey Fox is not a rare canid inhabiting much of the US and Central America. People know the Red Fox (imported from Europe for Virginia fox hunters before the Revolution) and the Coyote (which has invaded the Eastern US with the extirpation of the wolf), but few people know or ever see the crepuscular/nocturnal Grey Fox, a native canid.
I suspect that sometimes Grey Fox is mistaken for Coyote.
A cool fact about Grey Fox is their tree-climbing ability.
