Distribution and Habitat
The Snares Penguin is named after the place in which it breeds—the Snares Islands. The Snares Islands are a small group of islands off the coast of southern New Zealand. Although little is known of their range and migration outside of the breeding season, it is not thought that they migrate far in the winters. Occasional sitings have occurred on the coasts of Tasmania, southern Australia, the Chatham Islands, Stewart Island, and the southern New Zealand mainland. There are approximately 25,000 living pairs of Snares Penguins.
Snares Penguins nest in dense colonies under the tree cover of the Olearia forests or on coastal rocks. To build a nest, the penguins dig up shallow holes in the ground and layer the bottom with grass, leaves, twigs, peat, or pebbles. A small rim of mud is added to the rim of the nest to raise it above ground level. Vegetation at nesting sites dies dues to the dense nesting activities, and the colony moves to a new nesting site. Colonies nesting near streams may have some advantage, as the stream provides water for drinking and bathing. However, it is not essential that nesting colonies are located near a stream since many are far from any streams.

Famous quotes containing the words distribution and/or habitat:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
—William James (1842–1910)
