The largest bird in terms of wingspan is the wandering albatross (Diomedea exulans). It has the longest wingspan of any living bird, reaching an impressive average of around 8 to 11 feet (2.5 to 3.4 meters). Some individuals have been recorded with wingspans of up to 12 feet (3.7 meters). Wandering albatrosses are seabirds that spend the majority of their lives flying over the Southern Ocean. They have a characteristic white plumage and are known for their remarkable ability to soar and glide for long distances.
If we consider the largest bird by height or overall size, the title goes to the ostrich (Struthio camelus). Ostriches are flightless birds native to Africa and are the tallest and heaviest living bird species. Adult male ostriches can reach a height of about 6.9 to 9.2 feet (2.1 to 2.8 meters) and weigh around 220 to 330 pounds (100 to 150 kilograms). They have long legs, powerful bodies, and distinctive feather patterns.
