I'm Tana and I have two birds. My cockatiel Mister loves his cereal. Like PEOPLE cereal. He would fly down to me and land in my bowl of Cheerio's and eat them The only thing about Mister is that he HATES being touched. Barney, on the other hand, loves attention and being around me. Barney is very vocal and has a vocabulary of 10 words. His previous owner has not taught him much since Barney is 30 years old, but Barney is pretty funny. He loves to whistle and say "Hello, Barney" and sometimes says, "Hello, Baby". Barney can also laugh when someone else laughs or when he sees a video of himself.
That's cool. Just be careful with Cheerio's. They were the first solid food I gave my grey, but now they are saying the the large amount of zinc in the can harm birds who eat too many.
Not only the zinc but the HUGE amount of iron in them! Some of them have up to 45 0/0 and birds cannot consume more than 2 or they develop hemochromatosis -which has NO cure and it's fatal. Please, no human cereals whatsoever! Human nutritional needs are completely different from avian.
