Dinornis
The giant moa (''Dinornis'') is an extinct genus of ratite birds belonging to the moa family. Like all ratites it was a member of the order Struthioniformes. The Struthioniformes are flightless birds with a sternum without a keel. They also have a distinctive palate. It was endemic to New Zealand. Two species of ''Dinornis'' are considered valid, ''D. novaezealandiae'' of the North Island, and ''D. robustus'' of the South. In addition, two further species (new lineage A and lineage B) have been suggested based on distinct DNA lineages.
==Description==
''Dinornis'' may have been the tallest bird that ever lived, with the females of the largest species standing tall,〔Wood, Gerald (1983)〕 and one of the most massive, weighing 〔Amadon, D. (1947)〕 or 〔Campbell Jr., K. & Marcus, L. (1992)〕 in various estimates. Feather remains are reddish brown and hair-like, and apparently covered most of the body except the lower legs and most of the head (plus a small portion of the neck below the head). The feet were large and powerful, and the birds had a long neck that allowed them to reach tall vegetation. In relation to its body, the head was small, with a pointed, short, flat and somewhat curved beak.
