This can be seen today in both the rheas and ostriches. Struthioniformes contained all the ratites, such as the kiwis, emus, rheas, and cassowaries. It is a ratite and therefore related to the emu, ostriches, rheas and kiwis. Examples include cassowaries, chickens, crows and related corvids, kea, rallidae, and rheas. Hatchling greater rheas are grey with dark lengthwise stripes. Male greater rheas are very territorial during the breeding season. International trade in wild-caught greater rheas is restricted as per CITES Appendix II. Where they occur as pests, farmers tend to hunt and kill greater rheas. The inner part of the peninsula is inhabited by rheas, guanacos and maras. The ratites are large flightless birds, and include ostriches, rheas, cassowaries, kiwis and emus. They include tanagers, rheas, tinamous, curassows, antbirds, ovenbirds, and toucans. The greater rheas live in open grasslands, pampas, and chaco woodlands. However, Linnaeus (1758) placed cassowaries, emus, ostriches, and rheas together in "Struthio". The rheas are large flightless birds native to South America. The rheas in Germany are legally protected in a similar way to native species.
