I did a search and learned that they were originally from South America and either migrated here or were brought here by people as pets and are considered an invasive species here in FL. I had no idea! ---
"Muscovy ducks can be found in high densities in Florida. Muscovies found here are often a result of illegal release, often for ornamental purposes or as escaped pets.
There are some strict laws in Florida surrounding Muscovy ducks. While it is legal to own Muscovies, it is a federal crime to release them into any wild space."
So basically, if these 31 ducklings decide to make my backyard area their home, I couldn't take them and relocate them somewhere else in the wild. I can however shoot them to be rid of them lol....but of course I would never ever do such a thing! But I do find it odd that you can't relocate them to somewhere else but you're allowed to snuff their lives out. Strange law.
