Assuming you mean unlabeled turtle?
I'd guess it's probably Roti Island Snake-necked Turtle, but someone more familiar with Bronx can probably confirm the species.
@Great Argus Fixed it, I always seem to do that at least once when uploading a batch of photos, no idea why! Thanks for the species guess. I was surprised, and disappointed, by the number of unlabeled animals I saw.
I'm not sure what this is but it's likely a Roti Island. The zoo didn't even display this species until a couple years ago and now they're all over the place.
