What is Seriema?

A seriema is a South American bird belonging to the family Cariamidae. These birds are primarily found in the grasslands and wooded regions of southern-central South America.1

There are two distinct species:

  • Red-legged (crested) seriema (Cariama cristata): This bird stands about 60 cm (2 feet) tall and features long legs and a long neck. It has red legs and a red beak, with brownish plumage and bluish skin around the eyes.1
  • Black-legged (Burmeister’s) seriema (Chunga burmeisteri): Also known as the gray seriema, this species inhabits wooded areas and is characterized by a darker, grayer appearance, a shorter crest, and shorter legs.1

Seriemas are known for their varied diet, which includes insects, snails, reptiles, and berries. While they inhabit grasslands, they typically build their nests in bushes or trees.1

What makes the red-legged seriema’s call unique?

Sorry, the Britannica knowledge base does not contain information regarding the specific characteristics or uniqueness of the red-legged seriema’s call.

Seriemas, which belong to the family Cariamidae within the order Gruiformes, are generally considered to be related to cranes and bustards. While they are distinct, long-legged South American birds, their classification has historically been debated, with some earlier taxonomies even grouping them with birds of prey.

The provided search results do not establish a direct evolutionary link between modern seriemas and specific prehistoric bird species like Archaeopteryx or Hesperornis. While the fossil record documents the evolution of birds from the Jurassic Period through the Cretaceous Period, the specific ancestral lineage of the Cariamidae family is not detailed in the available data.
