Glad to hear its normal. Sometimes when you take in a rehomed bird you never know what kind of habits or issues they have. He lived with a man before so he has picked up some pretty disgusting "man" noises. He sounds like he is burping, farting and maybe the worse one is he makes a noise like he is hocking a lugy(sp?) and spitting it out. Pretty funny but gross at the same time He also sounds like he has been watching a lot of Sci-Fi movies! Lots of ray gun and space ship sounds! I have to laugh at him because he is so cute. He is very smart and has already learned a few new things just in the past couple of weeks. I'll get a few pictures of him posted for all to enjoy. Thanks!
