I have always had Maxi Pionus here and usually they are very chill easy going birds who are mostly quiet and self sufficient.
They love to hang out with you and check out what you're doing and get scritches and treats.
Lurch was a used parrot who was mad at the world for taking his person away and then being treated badly by the rest of the family who was stuck with him.
He was quick to bite without warning and just not a happy camper. It took me 5 years to earn his trust and love but we got there and he was quite fond of me and didn't try to bite as fast or hard because he learned I would heed his warnings and not bother him till he was in the mood to hang out with me.
He would fly after me all over the house once we had a understanding with each other and loved Taco Bell and toast.
Nerd bird was my first Maxi and was skinny and shy but he loved and trusted me completely and only bit when hurt or scared.
He loved to finger wrestle and would scream and pretend to bite me like he wanted to kill me and bury me in the back yard, but if I went ouch he'd stop and be mortified that he hurt me.
We had sll kinds of games we'd play like come in the door from work and run at his cage screaming touching bird and try to tap his wings. He scamper across the top of his cage and slide down the back and then chortle to himself and look like you missed me again.
He would be very put out if we didn't do it every work day.
He knew what my car sounded like and would get excited when I was at least two blocks away and knew what time I normally got home.
We grew up together from 78 to 2009.
Now I have Dobby and he's the gentlest Maxi I've ever known. He bluffs a good game but refuses to bite, is very outgoing, and the best acrobatics flyer I've ever had.
He is in love with my sister and rides with her everywhere when he's out. He doesn't hate me and will step up when ever I ask but she's the only one allowed to scritch him or wrestle with him, the same as Nerd used to do.
Nerd was wild caught but didn't fly well and was happy with his lot in life. He spoke wild Pionus and I spoke it back, we understood each other perfectly. He made flock calls and noises no other Maxi I've known make and had a jungle penetrating flock call BUUUWEEP!
Lurch talked and kept learning new words, Dobby has his favorites he announces when he's walking or excited. Dobby, Dobby good boy etc.
I think from what I've seen the Blue head are very similar in attitudes and size to the Maxi and the Maxi is the biggest one.
White heads are smaller and maybe a bit more shy but I know Maximilians and love them.
As you can see each one is their own soul with a unique personality with similarities to each other.
