were washed into lakes and swamps or buried in sand-dunes and river alluvium. In Glenmark Swamp, Canterbury, the remains of more than a thousand have been found, and in Southland fully four hundred skeletons were discovered within a radius of twenty-five feet.
Following the Pleistocene age the moas increased as the climate became more equable, and when the Maoris arrived they were plentiful in both islands. In vague Maori legends the moa's extinction is ascribed to fire and earthquake, but it is generally believed by authorities that the Maoris themselves exterminated the bird, probably three or four hundred years ago.
Of living birds New Zealand has a great variety. The land birds, which are far outnumbered by water and shore birds, are noted for their difference from the land birds of all other countries. Three of them—the kiwi, weka and kakapo—cannot fly, and the fern bird, now seldom seen, flies weakly.
