Penguins are excellent walkers

The Southern Hemisphere's cold-climate seacoasts are home to flightless birds, which burn a lot more calories while walking or running than other animal species of the same weight. Even while penguins' efforts to migrate may appear useless and tiresome, a recent study by the University of California, Berkeley experts revealed how waddling aids the penguins in energy conservation. According to the researchers, the waddling study has ramifications not only for penguins but also for expectant mothers and other people who have trouble moving around owing to illnesses, neurological conditions, or obesity.

The researchers compare the energy-saving waddling of penguins to the back-and-forth motion of an inverted pendulum. The energy of side-to-side motion is conserved after each swing when the penguin is quiet and ready for the next swing. This energy is transformed into motion on the return swing when the penguin rocks back to its upright position. As the penguin stops at the other extremity, the energy is once more stored. The ability to recuperate up to 80% of the energy used by penguins while they sway makes them 20% more efficient than humans. Because of how they move waddle penguins can roam and hunt even after abstaining from food for extended periods.
