Video Doorbell2 motion alerts

I am not sure if this one has been asked and answered. I searched and could not find any, so thought I would ask. My Ring Doorbell2 give me motion alerts every now and then. However, there is no one or nothing in its proximaty. I do have some plants and their leaf flaps when we have wind. Does that trigger a motion sensor because of that? If yes, is there a way to fix that? Please kindly advise.
