Rheiformes is an order that contains the family Rheidae (rheas).[3] It is in the infraclass Paleognathae, which contains all ratites. Extant members are found in South America. While the IOC World Bird List and the Clements Checklist categorise Rheiformes as its own order,[3][4] the BirdLife Data Zone includes rheas, along with ostriches, tinamous, cassowaries, emu, and kiwis, in the order Struthioniformes.[5] Of the two extant species of rheas recognized by the IUCN Red List, (As of 2022), Rhea americana is listed as near threatened,[6] while Rhea pennata is listed as least concern.[7] From 2014 to 2022, the IUCN recognised Rhea tarapacensis as a separate species, and listed it as near threatened in its last assessment in 2020;[8] in 2022, it was again recognised as a subspecies of R. pennata.[7](Taxonomy)
