What is the biggest bird?

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

Here's some information about it:

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

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

• Diet: Ostriches are omnivores, feeding on a variety of plants, seeds, fruits, and insects. They'll also occasionally eat small reptiles and rodents.

• Distinctive Features: Ostriches are easily recognized by their long necks and legs, powerful legs with two toes, and relatively small heads. They have long, strong necks and feathers that are generally black and white in males, and brown and gray in females. Their powerful legs enable them to kick with tremendous force, a vital defense mechanism.

• Flightlessness: Despite their size, ostriches are flightless birds. Their large size and powerful legs are adaptations for running at high speeds, which they use to escape predators. They can reach speeds up to 45 mph (72 km/h) in short bursts.

• Social Behavior: Ostriches generally live in groups called flocks, although the size and composition of these flocks can vary depending on factors like food availability and the breeding season.

• Eggs: Ostriches lay the largest eggs of any bird species; a single egg can weigh about 3 pounds (1.4 kg).

It's important to note that while the ostrich is the largest by weight and height, other birds might have larger wingspans, such as the wandering albatross. But in terms of overall mass and stature, the ostrich reigns supreme.
