Seriemas are large, long-legged birds that live in South America.

They are the only living members of their bird family. These birds live in many places like Brazil, Bolivia, Argentina, Paraguay, and Uruguay. You can find them in grasslands, savannas, and dry woodlands. They are among the largest ground birds in the Neotropics. Only the rhea is larger than them in that area.

Their name comes from Tupian languages and means "crested."

These birds have a very interesting way of moving and eating. They have long necks, long tails, and long legs. However, they have short wings because they prefer to run on the ground. They only fly for short distances or to escape from danger. When they find small reptiles, they use a special way to eat them. They beat the prey against the ground or a hard surface. This helps break the bones and makes the food easier to eat.

They also have sharp claws, including a very curved second toe claw.

Scientists have studied how seriemas are related to other birds. They used to think seriemas were related to cranes. Now, researchers place them near falcons, parrots, and passerines. They are also thought to be the closest living relatives to the "terror birds." These were huge, meat-eating birds called phorusrhacids that lived long ago.

These extinct birds could grow as tall as a person. The seriemas belong to the order Cariamiformes, which is the only surviving lineage of that group.

There are two specific species of seriema living today. The red-legged seriema is the larger of the two. It grows to about 90 cm in length. It lives in eastern Brazil and central Argentina. The second species is the black-legged seriema. It is slightly smaller, measuring between 70 and 85 cm.

This bird lives in northwest Argentina and Paraguay. It prefers to live in scrub and open woodland.

Seriemas play an important role in their environment. They eat insects, snakes, lizards, frogs, and even small rodents. By eating these animals, they help the soil get more nutrients. They also often hang out near grazing livestock. They likely do this to find insects that the animals stir up.

When they feel threatened, they spread their wings to face the danger. They usually walk in pairs or in small groups. At night, they fly up to find shelter in the treetops.
