The Yellow-billed Teal is probably one of the cutest ducks Mother Nature has ever come up with. Even when fully grown, they still look like chubby little ducklings, making them perpetually adorable. Another curious and, to me, adorable thing about them is one particular behavior that is unique to them: after mating, they always take a swim alongside their partner. This teal comes from the south of South America, from countries like Argentina, Chile, Peru, Uruguay, Bolivia and Brazil. If you decide to travel to any of these places, you will see plenty of them, so they are under no risk of extinction for now. Still, since it is quite a long trip towards the end of the Southern Hemisphere, you can always visit the Animal Kingdom to see them! They are located at the Oasis area of the park, around the main entrance.
