What is the largest bird in the world?

The largest bird in the world by mass is the ostrich (Struthio camelus).

Here's some information about them:

• Size: Ostriches are flightless birds, and their size is a key distinguishing feature. Males can reach heights of up to 9 feet (2.7 meters) and weigh up to 345 pounds (156 kilograms). Females are typically smaller.

• Habitat: They are native to Africa, inhabiting savannas, grasslands, and woodlands.

• Diet: Ostriches are omnivores, feeding on a variety of plants, seeds, fruits, insects, and occasionally small reptiles or mammals.

• Speed: Known for their incredible speed, ostriches can run up to 45 mph (72 km/h) in short bursts, making them one of the fastest-running birds. They use their long legs and powerful muscles to achieve this speed.

• Adaptations: Their long necks and legs allow them to spot predators from afar. Their strong legs and powerful kicks serve as an effective defense mechanism. Their large eyes are also notable, being the largest of any land animal.

• Social Structure: Ostriches are usually found in small groups or flocks, and breeding pairs are fiercely territorial.

• Conservation Status: While their population is considered stable overall, certain subspecies are vulnerable or endangered due to habitat loss and hunting.

It's important to note that while the ostrich is the largest by mass, some birds, like the Andean condor, might have a larger wingspan. However, overall body mass is generally the accepted metric for determining the largest bird.
