Bird+Flight

My history is about the effect of geometry on the flight of birds. Depending on the shape they put their wings or tail in, that shape will pick up a gust of air and use it to push the bird into different maneuvers. For example, if a bird tilts its right wing up and its left wing down it will do a roll to the right, if reversed, it will do a roll to the left. Here's a link to more on it. Bird Flight
