The lemniscate motion occurs naturally in the flapping of birds' wings. The bird's vertical lift and wing sweep create the distinctive figure-eight pattern. The patterns vary with the different wing profiles. Compare the two possible lemniscate patterns by graphing them on the same polar graph: r² = cos 2θ and r² = cos (2θ + 1).
