It's really amazing the difference in personality in my 2 birds, I have 2 boys a 19 month old El, and a 7 month old Eddie. My older bird has been the perfect pet since the day he hatched, he's sweet , lovable and very calm. He doesn't try to stomp anything, likes the other animals, he comes when he's called and he puts himself to bed in the horse barn as soon as the sun begins to set so all I have to do is slide the door closed. He would like to spend the whole day in my lap eating grapes, he's my best bud. And then there's Eddie, I got Ed when he was about 3 months old, Ed is wild, he runs and jumps all day everyday, he stomps everything, he has deflated his rubber balls, he kicks his food bowls, any leaf that falls he hisses at and stomps, just about drove himself crazy this fall, he chases birds, dragonflies, frogs, everything. He is never calm. He will not go to bed at night, every night it's a big fight to get him in the barn, once he's in he has a snack and goes to bed next to El. I try to make sure he gets lots of petting everyday ,but even when he's in my lap being cuddled he's intense about it, he gets as tight to me as he can, closes his eyes tight and buries his face in my clothes. He's just an uptight character. I hope he mellows as he gets older for all our sake,lol
