One thing to keep in mind is that if you don't handle the bird every day, it will stop being tame.
I think umbrella cockatoo is best. they get along with other animals and thhey talk and sing and do a head dance.
I have Zebra Finches currently and have experience with different animals that need lots of attention, and I've even cared for my friend's Conure, but I really love the affection the bigger birds (mostly) give. I don't exactly have much space in the room I plan to have the Cockatoo in, therefore, I'm looking into the smaller species, but anything's possible, I guess. There are some days in which I am not really able to interact with my pets much (let alone people I know). So, if possible, can you list the bird you feel is right for me and its attention and cage requirements and possibly a general price range for the bird itself? And maybe some experiences?
I went to a bird store with my friend once that lets you pet and interact with the birds they are selling, and I fell in love with an Umbrella that climbed onto my arm. That was a while ago, so I'm hoping they still do that when I go back to browse...
Thanks!
