A yellow-headed Amazon (Amazona oratrix), which I learned from iNaturalist is classified as endangered. AFAIK it's just the quiet and the food that keeps the birds there.

A wood stork walks past two agoutis (a kind of rodent) at the Xaman Ha Aviary at Playa del Carmen, QR, Mexico. All but one small area was completely open so I suppose the birds and agoutis could come and go.

Look ma, no hands (or feet)!

Opposable digits on the hands and feet AND a tail that is strong enough to support the body weight. I was surprised at how much time the monkeys spent upside down.

A baby spider monkey at Punta Laguna reserve, Yuacatan, Mexico. My guide, Francisco, reckoned it was ~2 months old. It was foraging independently but sometimes hitching a ride on an adult.

I was observing this spider monkey in the trees at Punta Laguna reserve, Yucatรกn, Mexico with a guide when it decided to come down to the ground right in front of us to gather some fruit. Metadata says 2.83-3.3m away.
