The are absolut funny birds.. We once addopted one, his previous owner passed away.. And it needed a home for a few months, so a relative living in an other country could come and pick him up. We knew it was named Coco but not how old he realy was. But alledged over 30 years old. And he was a very vicious but true comedian at heart, he accepted nothing and nobody near his cage. Feeding him was a challenge not to loose a finger. But he could talk and sing like a champion and learned realy fast. He wistlled complete tunes such as the Radetzky March from Johann Strauss. Back then we also had a dog and he always was bullying the dog with making noises to draw her attention and call her name and say "Come!?" with a very affectionate tone. Than the studip dog came close to look and snif and when it was close enough the darn parrot squealed and banged his beak into the cage to startle the dog. He did this at least once a week.
One night i came home from a night drinking with friends.. And Coco went completely bonkers and saying "Coco sweet" and maded kissing sounds and wanted out of the cage. I was tipsy enough to take my changes, he won me over and opened it. He immediately came to me climbed onto my shoulder and sat for over an hour talking like mad nibbling my ears, nose and hairs and acted realy happy. All of a sudden the sweetest and best parrot one could imagine. Next morning after me taking a shower and having breakfast he was back to visious again.
After asking around it seemed his previous owner was an Alcoholic.. It was the smell of beer the bird associated with his best friend. That made the difference for him, drink a beer and he was your best friend ever and eat out of your mouth.
No beer smell and he would try to kill you.
