Ostriches are the largest birds in the world, known for their long necks and powerful legs. They can run at speeds of up to 45 miles per hour, making them the fastest-running birds. Unlike most birds, ostriches cannot fly, but their strong legs help them escape predators quickly. They are native to Africa and live in open grasslands and savannas. These fascinating creatures can grow up to 9 feet tall and weigh over 300 pounds. Ostriches have large eyes that provide excellent vision, allowing them to spot danger from afar. They are also known for their unique mating dances and can lay the largest eggs of any bird, measuring about 6 inches in diameter.
