← Nature & AnimalsWhich outcome characterizes brown pelican soaring flight when encountering an updraft?
A)Decreased muscular energy aerial thermalling✓
B)Increased wing flapping autoration descent
C)Enhanced lift reducing induced drag
D)Decreased stability increasing parasite drag
💡 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.
