It's the Coriolis force that depends on velocity wrt the rotating frame. In the case of a bird not moving with the ring and remaining fixed relative to a star, it still "feels" the centrifugal force. The only difference is that the Coriolis force acts even stronger in the opposite direction and pulls the bird into what looks like a circular trajectory from the rotating frame. | |
