My

has recently discovered mirrors. Our house is full of them and now that his wings are grown in he can fly pretty well and we've just began flight training. He has not discovered that it is him in the mirror and he does mating displays at his reflection for basically as long as I allow him to. At least i think its mating and not aggression. So my question is, do i just let him have the mirrors as his guilty pleasure and hope in time he discovers they aren't other birds? or should i immediately remove him from the mirrors when he flies to them?
thanks
