Little Penguin - Distribution and Habitat

Distribution and Habitat

See also: List of Little Penguin colonies

The Little Penguin breeds along the entire coastline of New Zealand, the Chatham Islands, and southern Australia (including roughly 20,000 pairs on Babel Island).

Little penguins have also been reported from Chile (where they are known as Pingüino pequeño or Pingüino azul) (Isla Chañaral 1996, Playa de Santo Domingo, San Antonio, 16 March 1997) and South Africa, but it is unclear whether these birds were vagrants.

Rough estimates (as new colonies continue to be discovered) of the world population are around 350,000-600,000 animals. The species is not considered endangered, except for the White-Flippered subspecies found only on Banks Peninsula and nearby Motunau Island in New Zealand. Since the 1960s, the mainland population has declined by 60-70%; though there has been a small increase on Motunau Island. But overall Little Penguin populations have been decreasing as well, with some colonies having been wiped out and other populations continuing to be at risk. However, new colonies have been established in urban areas.

The greatest threat to Little Penguin populations has been predation (including nest predation) from cats, foxes, large reptiles, ferrets and stoats. Due to their diminutive size and the introduction of new predators, some colonies have been reduced in size by as much as 98% in just a few years, such as the small colony on Middle Island, near Warrnambool, Victoria, which was reduced from 5000 penguins to 100. Because of this threat of colony collapse, conservationists pioneered an experimental technique using Maremma Sheepdogs to protect the colony and fend off would-be predators.

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)

    “Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.”
    —John Dewey (1859–1952)
