Ok I am kinda new here but I am going to jump right in on this one.
We purchased our B&G at the bird fair in Tallahassee Fl about a month ago, he is so sweet but yes he requires much more attention than our african grey and yellow amazon. He is in his cage during the day when we are at work, but as soon as one of the kids get home they let him out, if they didn't you would have a very upset fella on your hands and he lets you know too.
Simba is 1 year old and yes he will let you touch his tail
.
He wants to be where ever the rest of the flock is and that includes at the dinner table.. He wants to eat what ever you are eating.
He is not a screamer but when I run the vacuum he gets pretty loud..
Just be prepaired to spends lots of time with any macaw you get
