What are some animals that start with y in South America?

You're right, there aren't many common animals that start with "y" in South America. In fact, it's pretty tricky!

However, we can find a few options, though they might not be the first things that come to mind:

* Yacare Caiman (Caiman yacare): This is a type of caiman found in wetlands of South America. It's not as large as the Black Caiman and has a distinct "Y"-shaped snout.

* Yellow-headed Caracara (Caracara plancus): While not starting with "y," these birds are commonly called "Yacare Caracaras" in some regions of South America because they often hang around caimans, picking up scraps.
