Parrotlets are so much fun! So full of life and very entertaining to watch.
They are pretty messy, but thankfully they are small, so it's easy to clean up. My guy likes to chuck his less than favorite pieces of food to the bottom of his cage, but he can't throw them very far.
Quirks...they are called mini Amazons. They can be moody, aggressive, etc. However, their pros outweigh those possible cons. My guy can speak very well and is just hilarious! He also loves his scritches and wants to be on me all the time. He plays well with his toys and is not loud. A lot of people say they don't make good first time parrots, but mine was my first "parrot" (I had a budgie before, but she is not tame and sweet as pie), and we are doing just fine together.
