History
Archeological work has revealed that Xenicus lyalli was widespread on the main islands of New Zealand in earlier times. Its disappearance from there was probably due to predation by the kiore (Polynesian Rat, Rattus exulans), which may have been introduced by the Māori. The presence of a flightless bird on an island separated from the mainland by 3.2 km may seem puzzling, along with the presence of Hamilton's frog (which is killed by exposure to salt water). One possibility is that rafts of vegetable matter allowed them to cross, although the absence of kiore would then be surprising. Stephens Island, along with the other islands in the Marlborough Sounds, was joined to the mainland during the last ice age due to the lower sea level, so the native animals may have arrived then.

Famous quotes containing the word history:
“In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.”
—Henry David Thoreau (1817–1862)
“America is, therefore the land of the future, where, in the ages that lie before us, the burden of the World’s history shall reveal itself. It is a land of desire for all those who are weary of the historical lumber-room of Old Europe.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“While the Republic has already acquired a history world-wide, America is still unsettled and unexplored. Like the English in New Holland, we live only on the shores of a continent even yet, and hardly know where the rivers come from which float our navy.”
—Henry David Thoreau (1817–1862)
