I'm actually thinking a black headed spider monkey.

I could've sworn I took that at the gorilla enclosure, but looking at other baby gorilla photos, this little bugger doesn't look like one. Definitely not a baby chimp either...

Going to need some zoologist help on this one!

This was taken at Standley Lake in Westminster, CO. I didn’t have bug spray that evening and got chewed up by the mosquitoes - still worth it!
