I'm kind of in the opposite position. I have had birds for nearly 13 years now, and recently, my 2 year old nephew came to live with me, along with his parents.
My nephew, Hugh, does ok with dogs. Cats on the other hand? Well, not so well. It takes a very tolerant cat to ignore him. The cats he grew up with tolerate him far better than my cats do, and it's been just over 2 months since he's known my cats. Hugh likes to lay on his cats, strangle them, shove them, poke them in they eye. My cats can barely stand Hugh touching them. I know Hugh probably doesn't do those things to be mean, he just doesn't understand yet that you can't behave that way with animals.
I am reluctant to allow him to interact with the birds, although only one might allow it (most aren't tame). He enjoys seeing them and watching them, but until he learns to behave better with the cats, I take more caution with the birds.
That said, he does seem to take after his aunt (me) a lot! Even though an ocean separated us for most of his two years, he seems to behave more like I did as a toddler than my sister! LOL
