Cariamidae

The seriemas are the sole living members of the small bird family Cariamidae, which is also the only surviving lineage of the order Cariamiformes. Once believed to be related to cranes, they have been placed near the falcons, parrots and passerines, as well as the extinct Phorusrhacidae (terror birds). The seriemas are large, long-legged territorial birds that range from in length. 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". Description Both species are around long (the red-legged seriema is slightly bigger than the black-legged, with 90 and 70–85 cm respectively). The seriemas 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. Also, they are among the largest ground-dwelling birds endemic to the Neotropics (only behind rheas). They are brownish birds with short bills and erectile crests, found in fairly dry open country, the red-legged seriema preferring grasslands and the black-legged seriema preferring scrub and open woodland. Also, they give loud, yelping calls and are often heard before they are seen. Furthermore, they have sharp claws, with an extensible and very curved second toe claw. Classification
