Cosmo is not as friendly as my Sammi - she's a lesser sulfur crested cockatoo. I can handle Cosmo as long as my husband is not around, if Ed is within sight Cosmo will lunge at me with full intent of removing my nose or a finger!

My daughter can't go anywhere near him, as a matter of fact to give you a glimpse of his personality. Cosmo's stand is at the bottom of our steps, he will hear Alyssa starting to come down the hallway, just as she comes within sight, Cosmo lets out a scream and then Alyssa screams!

He does it on purpose! You can just about see his tail feathers quiver with laughter!
He was just 2 last September so his vocabulary is building. One thing I think is amazing is he has 2 distinct voices - mine and Ed's! He will laugh like me and he will laugh like Ed. He has words he has picked up from me that he says in a higher voice and words that he has picked up from Ed using a lower voice.
My computer stand is right by his cage, he will pick up food in one foot and try to hit me with it! Of course, he won't do this when Ed is around!
He also likes to lure the dogs over to his stand, he will then climb down a toy so he is hanging in the lowest place possible and try to bite the dogs!
He is quite a character but I would say that a scarlet is not for everyone! He is very nippy and can be very loud.
