What is the largest bird in the world?

The largest bird in the world is the ostrich (Struthio camelus). It is a flightless bird that is native to Africa, and it can reach up to 9 feet (2.7 meters) in height and weigh as much as 320 pounds (145 kilograms).

Ostriches are unique in many ways. Not only are they the largest bird, but they also lay the largest eggs of any bird species. These eggs can weigh as much as 3 pounds (1.3 kilograms), and they are strong enough to support the weight of an adult human.

Despite their large size, ostriches are capable of running at speeds of up to 43 miles per hour (70 kilometers per hour), which makes them the fastest bird on land. They have long, powerful legs that enable them to cover great distances quickly, and their wings are used for balance and steering while running.
