Which outcome characterizes brown pelican soaring flight when encountering an updraft?

💡 Explanation

Pelicans utilize dynamic soaring by extracting energy from wind gradients through altitude changes causing decreased energetic demands via aerial thermalling, because the lift to drag ratio increases; therefore they conserve muscular energy, rather than flapping continuously.
