Health
In spring 2004, a previously undescribed disease killed off 60% of Yellow-eyed Penguin chicks on the Otago peninsula and in North Otago. The disease has been linked to an infection of Corynebacterium, a genus of bacteria that also causes diphtheria in humans. It has recently been described as diphtheritic stomatitis. However, it seems as if this is just a secondary infection. The primary pathogen remains unknown. A similar problem has affected the Stewart Island population.

Famous quotes containing the word health:
“It is always singular, but encouraging, to meet with common sense in very old books, as the Heetopades of Veeshnoo Sarma; a playful wisdom which has eyes behind as well as before, and oversees itself. It asserts their health and independence of the experience of later times. This pledge of sanity cannot be spared in a book, that it sometimes pleasantly reflect upon itself.”
—Henry David Thoreau (1817–1862)
“I still need more healthy rest in order to work at my best. My health is the main capital I have and I want to administer it intelligently.”
—Ernest Hemingway (1899–1961)
“Woman ... cannot be content with health and agility: she must make exorbitant efforts to appear something that never could exist without a diligent perversion of nature. Is it too much to ask that women be spared the daily struggle for superhuman beauty in order to offer it to the caresses of a subhumanly ugly mate?”
—Germaine Greer (b. 1939)
