Is this common or do I have a do-do bird?

That would be so great if he never realized he could fly so I didnt have to have him trimmed. Ofcourse, when we go anywhere now I dont allow him outside. He could get a wild hair up his butt, realize he has flight and poof... lord have mercy! Perish the thought!
Ever heard of a flighted bird that didnt fly because they didnt realize they could?

All he remains doing is fluttering to the floor/object as he always has... just way smoother and lands exactly where he wishes now, rather than sometimes falling short and having to walk the rest of the way.
He does, however, grab things with his talons and flaps his wings alot for exercise so Im not *to* worried. Just seems odd, a bird that doesnt realize he can fly.
