The bird that can run up to 70 km/h (43 mph) is the Ostrich. Ostriches are flightless birds native to Africa and are known for their long necks and legs. They are the largest bird in the world and can weigh up to 320 pounds. Despite their size, ostriches are incredibly fast runners and use their powerful legs to outrun predators. They also have large, powerful wings that they use for balance and steering while running. Ostriches are commonly raised for their meat, eggs, and feathers and are considered a valuable resource in many parts of Africa.
