This is how I typically flight train my parrots in the morning so that they can get some exercise. Instead of just putting their breakfast meal in their bowl, I have them fly to receive it bit by bit. This is much more healthy and natural for parrots than to just pig out from a bowl.
To have room for the camera, I put the perches a bit closer. Normally we make use of the longest distance possible to get more out of it.
