Contrary to the expectations of some scientists, the moa-nalo were not related to the large geese ( Anserinae ), such as the surviving nēnē , but instead to the ...

Most were heavy-bodied, with powerfully developed legs and greatly reduced wings. The last bones of the toes resembled small hooves, rather than claws as in most birds.
