Carlos is very happy to follow me around the house when I have him indoors.
If he did fly off he would return home and the end of the day providing he didn't get lost.
I do keep his wings (and very sharp nails) trimmed so that if he gets spooked he doesn't fly off and get lost.
When he isn't indoors he has a 8x6x4 foot cage with lots of toys and fresh palm leaves and lots of other things to keep him amused. He lets me know when he wants to come in and when he wants to go out.
Here is a better pic of him and you can see his outdoor home in the background.
