Final answer:
The behavior of birds, specifically their streamlined shape and formation flying, has been studied to improve wind power harnessing due to their efficiency in flight.
Step-by-step explanation:
The animal behavior that has been studied to help create more efficient harnessing of wind power is that of birds. When it comes to how drag has influenced evolution, we can look at how birds are streamlined for efficient flight. Migratory species, which fly large distances, have particular features such as long necks to reduce drag.
Notably, when birds fly in flocks, they often arrange themselves in a spearhead formation, which creates a streamlined pattern that minimizes air resistance and saves energy. This behavior has inspired engineers and researchers to design wind turbines that can harness wind power more efficiently by mimicking the aerodynamic properties of birds.
