Wings are probably clipped, so it can halfway power itself up to roof, but now can’t really fly elsewhere. It probably could get down to the ground or to a nearby tree, but think of it in the same manner as a cat. Technically the cat could get down from the tree, but it would have to act in a manner inconsistent with its entire past life (climbing backwards so the claws get grip). So, technically the parrot could get down, but it hasn’t ever been able to fly, so the action (flapping while on a downwards course) needed to get down just doesn’t seem an option to it. I would bet it’s the same feeling a person gets if they can climb/hike to a high point on a cliff, but then can’t jump down from it to the water.

Too many shrooms. Just let him ride it out

Yeah it was not trapped.

Stuck on a roof aka the owner wants it back
