1. Great picture thanks

You think that's a Muscovy? I've seen a lot of them, all weird. but none with that black mohawk.

2. Not sure;

was hoping someone would confirm.

First time I saw one was in Florida and had NO idea what it was!

3. Yes, it's a Muscovy Duck.

They're introduced and breed here in Florida.

They're native to Mexico, Central, and South America. Their range barely reaches Texas along the Rio Grande River.

Here's the spot where it's possible to see real wild ones, along the Rio Grande River in Salineno, Texas:
