Overview
The South Island Takahē (Porphyrio hochstetteri) represents one of the greatest resurrection tales in modern conservation biology. The largest living rail in the world, this flightless, hen-sized alpine herbivore was officially declared extinct in the late 19th century after European settlement introduced invasive mammalian predators. In 1948, after fifty years of presumed oblivion, physician Geoffrey Orbell stunned the scientific world by rediscovering a tiny relic wild population deep within a secluded glacial valley of Fiordland’s rugged Murchison Mountains.
Biology and Physical Characteristics
Weighing up to nine pounds, the takahē possesses a stocky, rounded body cloaked in iridescent olive-green and turquoise-blue plumage, supported by sturdy, thick coral-pink legs. Its most formidable anatomical feature is an enormous, triangular crimson-red beak backed by a swollen frontal shield that covers its forehead. The massive beak delivers intense crushing power, engineered specifically to strip fibrous alpine tussock grass stems and slice away the tough outer sheaths to access the tender, starch-rich inner succulent core.
Behavior and Ecology
Takahē are strictly terrestrial, flightless birds that form lifelong monogamous pairs defending expansive alpine territories of up to 40 hectares. Because snow tussock grass is low in nutrient density, adult takahē must forage almost continuously, spending up to 19 hours a day clipping and chewing grass stems, producing several meters of fibrous green droppings daily. During harsh winter months when heavy blizzards bury alpine meadows, pairs migrate down into sheltered subalpine beech forests to forage on fern rhizomes and mosses.
Conservation and Human Impact
Once pushed to the very brink of extinction by competition from introduced red deer and predation by stoats (Mustela erminea), the takahē has undergone one of the world’s most intensive recovery programs spearheaded by New Zealand’s Department of Conservation (DOC). Using captive breeding, artificial chick rearing, intensive predator trapping, and translocations to pest-free offshore islands, the total population recently surpassed 500 individuals, paving the way for historic releases back into traditional tribal tribal lands in Greenstone Valley.
Interesting Factoid
A single adult takahē can consume up to several hundred tussock grass stems every single day, carefully plucking each blade with its foot and shearing it like hedge-clippers to eat only the sweet bottom two centimeters.
