Yeah, I consider it silly/destructive to exclude apes from monkeys:

Apes emerged within monkeys as sister of the Cercopithecidae in the Catarrhini, so cladistically they are monkeys as well. However, there has been resistance to directly designate apes (and thus humans) as monkeys

A.k.a. "humans are not animals" with extra steps, which has always been used for dodging moral questions.

And it's just a shot from top-down at an angle, so you can't see the rest of his body or neck.

It looks like a chimpanzee to me, so this would be the diet:

The chimpanzee is an omnivorous frugivore. It prefers fruit above all other food, but it also eats leaves, leaf buds, seeds, blossoms, stems, pith, bark, and resin.
