What is the biggest bird in the world?

The biggest bird in the world, by weight, is the ostrich ( Struthio camelus).

Here's some information about it:

• Size: Adult males can reach heights of up to 9 feet (2.7 meters) and weigh up to 345 pounds (156 kg). Females are generally smaller.

• Habitat: Ostriches are native to Africa, inhabiting savannas, grasslands, and sparsely wooded areas.

• Diet: They are omnivores, feeding on seeds, plants, fruits, insects, and occasionally small animals. Their diet is largely dependent on the season and availability of food.

• Characteristics: They are flightless birds with long legs and necks, powerful legs for running, and two toes on each foot. Their large eyes are the largest of any land animal. They have excellent eyesight and hearing.

• Speed: Ostriches are the fastest-running birds, capable of speeds up to 70 km/h (43 mph) in short bursts.

• Social Behavior: They typically live in groups called flocks, but the size and composition of these flocks can vary depending on the season and the availability of resources.

• Reproduction: Ostriches are polygynous, meaning one male mates with several females. The females lay their eggs in a communal nest.

• Conservation Status: While not currently endangered, ostrich populations are under pressure from habitat loss and hunting.

While the Andean condor has a larger wingspan, the ostrich significantly outweighs it, making it the heaviest bird in the world.
