This is a three-toed Bradypus species of sloth (but which one?)
as portrayed in tiles on the stairway of the NYC subway stop (A-B-C)
at 81st and Central Park West. (ISO, no zoom, no flash).

It's harder to tell when you can't count the toes!
Hi! I found your blog through nature blog. I really love it!
It's definitely a three-toed (Bradypus). Identifying the species is a bit harder.
