Silverback Out for a Stroll

More camera trap magic: This is a silverback Cross River gorilla (Gorilla gorilla diehli), caught with a camera trap in Nigeria’ s Afi Mountain Wildlife Sanctuary. Cross River gorillas are the rarest of the four gorilla subspecies – numbering fewer than 300 individuals and found only in the forested, mountainous border region of Nigeria and Cameroon.
