Cockatoos, seem to need lots of attention, as they are sweet when you give th em enough attention, but then if you don't give them as much as needed, theyw ill get upset, and birds can't really say I'm mad, the way they say it is by biting them. I know one bird that bites so mu ch that it will warn you, because of people sayin ow each time he b ites, he says ow before he bites, it's quite fu nny, he has yet to bite me. I guess it's because, ummmmmm, I'm not afraid of getting bit. I go to bird stores all the time, and hold the birds, and they will say "watch out he will bite" all they do too me, except a quaker, will k iss, the quaker, is the first one that I found that just can't stand me. Soi I don't mess with him, unless it's to give him a bath, then he's all lovey dovey.
