The Emu is the second largest bird in the world. Amazingly they’re the only bird species that have calf muscles and cannot walk backwards. Emus are also known for their fast sprinting and long distance running, running at speeds of 31 mph (50 km/h). Using their wings as steers, they can turn 180 degrees while running at full speed. Predators like cats will have a hard time catching these birds.
It is a fact that the male incubates the eggs, during which he does not eat, drink, or defecate, and stands only to rotate the eggs.
