The largest species of bird in the world is the ostrich (Struthio camelus). Native to Africa, ostriches can grow up to 9 feet tall and weigh between 220 to 350 pounds. Known for their long legs and ability to run at speeds up to 45 miles per hour, they are flightless birds that rely on their speed for survival. Ostriches also possess large, powerful legs capable of delivering formidable kicks to predators. Their unique characteristics make them an iconic species, and they are also farmed for their feathers, skin, and eggs.
