The ostrich is the largest living bird, native to Africa. It can grow up to 9 feet tall and weigh between 220 to 350 pounds. Unlike most birds, ostriches cannot fly, but they are excellent runners, capable of reaching speeds up to 45 miles per hour. Their long legs and large feet help them cover ground quickly. Ostriches have distinctive features, including a long neck and large eyes, which provide them with good vision. They are omnivores, primarily eating plants, seeds, and insects. Ostriches are also known for their unique mating rituals, which involve elaborate displays and vocalizations to attract partners.
