The seriemas are the sole living members of the small bird family Cariamidae, which is also the only surviving lineage of the order Cariamae. Once believed to be related to cranes, they have been placed near the falcons, parrots and passerines, as well as the extinct terror birds. The seriemas are large, long-legged territorial birds that range from 70 to 90 cm. They live in grasslands, savanna, dry woodland and open forests of Brazil, Bolivia, Argentina, Paraguay and Uruguay. There are two species of seriemas, the red-legged seriema (Cariama cristata) and the black-legged seriema (Chunga burmeisteri). Names for these birds in the Tupian languages are variously spelled as siriema, sariama, and çariama, and mean "crested".
Both species are around 90 cm (35 in) long (the red-legged seriema is slightly bigger than the black-legged, with 90 and 70–85 cm respectively). They forage on foot and run from danger rather than fly (though they can fly for short distances, and they roost in trees). They have long legs, necks, and tails, but only short wings, reflecting their way of life. They are among the largest ground-dwelling birds endemic of the Neotropics (only behind rheas).
They are brownish birds with short bills and erectile crests, found on fairly dry open country, the red-legged seriema preferring grasslands and the black-legged seriema preferring scrub and open woodland. They give loud, yelping calls and are often heard before they are seen. They have sharp claws, with an extensible and very curved second toe claw.
