largest living member of the Rallidae family.</p> <p>The remaining species are the remnant of the South Island population resulting from speciation.  The North Island species <em>Porphyrio mantelli</em> which was taller and thinner boned is extinct. It is only known from skeleton remains.</p> <p>An adult takahe is stocky, weighing up to 3 kg (6.5 lbs), standing up to 50 cm (20 inches) tall, and reaching 63 cm in length, about the size of a chicken.   Females are slightly smaller than the male.  As typical of most of the flightless birds, it has short stout but strong, red legs.</p> <p>Every part of the takahe is solid, except its' small wings of course, that are only used for display.  Its' impressive red beak is so solid it looks strong enough to cut number eight fencing wire.</p> <p>Takahe are similar in appearance and coloration to the smaller pukeko <em>Porphyrio porphyrio</em>, which is another native rail, but common worldwide.</p> <p>Pukeko still fly, but poorly for short distances in escape in the open.  They have been seen on rare occasions roosting in small trees. Their favoured habitat is a lake edge, but they are also grazing birds, successfully adapting to pasture, and are found on low-lying farmland and near roads where drains attract them.</p> <p>In the Fiordland native habitat, curled, mid-ribbed, and broad-leaved snow tussock grasses provide food and shelter for takahe.  Nesting pairs build a raised ground nest of snow tussock grasses in October after the snow has melted.</p> <p>Eighty percent of the one to three eggs laid each year hatch after 30 days of incubation, which is shared by the male and the female.  Chicks are fed by both parents for three months.  Only one chick will normally survive the first winter.</p> <p>Takahe translocated from remote alpine habitat have easily adapted, feeling quite at home in the environment of predator-free offshore islands, and unafraid of humans.</p></td> </tr> <tr> <td height="6"> </td> </tr> <tr> <td><img src="lineDot250.gif" width="258"></td> </tr> <tr> <td height="9"> </td> </tr> <tr> <td><p style="font-size:9px"><strong>Below: A South Island takahe feeding its' chick.  Copyright © Geoff Moon.</strong></p></td> </tr> <tr> <td height="11"> </td> </tr> </table> </td> </tr> </table> </td> <td valign="top" width="225"> <img src="takahe.jpg" border="0" width="225" alt="Takahe"> <table cellspacing="0" cellpadding="14" width="225"> <tbody> <tr> <td bgcolor="dae8de" valign="top"><h2>Missing for more than half a century - life in an edge ecology .....</h2> <p>Takahe provide another intriguing story of life on the edge for New Zealand's endangered avifauna. They were once found every-where on both mainland islands.</p> <p>The first specimen recorded by Dr Gideon Mantell was caught alive on Resolution Island in 1849 by a seal hunter's dog.  Another three takahe were found the same way, but this was all that was known about the bird in 1900 so it was assumed to be extinct.</p> <p>This in no way deterred Dr Geoffrey Orbell, an amateur naturalist from Invercargill, from an intensive search in a wet, remote region of the Murchison Mountains in Fiordland.  It is a place where 250 inches of rain fall in a year and many areas are still untrodden by humans.</p> <p>On his first visit footprints were found, however, on a second visit in 1948, two takahe were rediscovered near the shores of Lake Orbell, causing a sensation amongst ornithologists throughout the world. In that year 400 birds were found in alpine tussock grassland of the Murchison Mountains and two adjoining ranges.</p><br><br /></td> </tr> </tbody> </table> </td> </tr> <tr> <td valign="top" colspan="2"><img src="takaheChickMoon.jpg" width="503"></td> </tr> <tr> <td colspan="0" height="16"> </td> </tr> </table> </td> <td valign="top" width="293"> <table cellpadding="0" cellspacing="0" border="1" bordercolor="#679797" width="293"> <tr> <td align="center" width="210" bgcolor="#ffffff"><br><a href="TNFdonation.htm"><img src="takaheDonate210.gif" border="0" width="210"></a><br> <table cellpadding="0" cellspacing="0" border="0" width="230"> <tr> <td width="12"> </td> <td><p style="font-size:10px"><font color="#679797"> The total amount of each takahe donation made to <strong>Terra Nature Fund</strong> will be used for predator control, nest monitoring, bird transfers, egg incubation and hand-raising by <strong>New Zealand Department of Conservation</strong> biologists.</font></p> <p style="font-size:10px"><font color="#679797">See more on the <a href="#" onClick="MyWindow=window.open('http://doc.govt.nz/Conservation/001~Plants-and-Animals/001~Native-Animals/Takahe.asp','MyWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=560,height=600'); return false;"> <strong>Takahe Recovery Programme</strong></a>, which is managed by the <a href="#" onClick="MyWindow=window.open('http://www.doc.govt.nz/Conservation/001~Plants-and-Animals/Threatened-Species-Trust-Programme.asp','MyWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=555,height=600'); return false;"> <strong>Threatened Species Trust</strong></a>.</font></p> <p style="font-size:10px"><font color="#679797">Contributions made to Terra Nature Fund are tax deductible in the United States ..... donations made directly to the Takahe Recovery Programme are not.</font></p><br><br></td> </tr> </table> </td> </tr> </table> <table cellpadding="20" cellspacing="0" width="293" bgcolor="#dae8de"> <tr> <td><h3><font color="#ff1111">2006 IUCN Red List of Threatened Species</font></h3> <p style="font-size:10px"><font color="#ff0000">North Island takahe <em>Porphyrio mantelli</em> Extinct</font></p> <p style="font-size:10px"><font color="#ff0000">Takahe <em>Porphyrio hochstetteri</em> Endangered</font></p> <h3><font color="#222222">2012 New Zealand Threat Classification System</font></h3> <p style="font-size:10px">North Island takahe <em>Porphyrio mantelli</em> Extinct</p> <p style="font-size:10px">South Island takahe <em>Porphyrio hochstetteri</em><br> Nationally critical</p> <p style="font-size:9px"><strong>Photo left: Takahe <em>Porphyrio hochstetteri</em>.  Crown copyright © Department of Conservation.</strong></p></td> </tr> </table> <table cellspacing="0" cellpadding="0" width="291" border="1" bordercolor="#679797" bgcolor="#dae8de"> <tr> <td> <table cellspacing="0" cellpadding="0" width="289"> <tr> <td height="30"> </td> </tr> <tr> <td align="center"><a href="#" onClick="MyWindow=window.open('takaheNotornisExpedition_NZonScreen.htm','MyWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=580,height=587'); return false;"><img src="NZonScreenLogo_aquaBg266.gif" width="173" border="0"></a></td> </tr> <tr> <td align="center"><a href="#" onClick="MyWindow=window.open('takaheNotornisExpedition_NZonScreen.htm','MyWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=580,height=587'); return false;"><img src="takaheNotornisExpedition_NZonScreen289.gif" width="289" border="0"></a></td> </tr> <tr> <td height="3"> </td> </tr> </table> </td> </tr> </table> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td height="9"> </td> </tr> <tr> <td><h2>Takahe protection ......</h2> <p>Like the moa, takahe numbers shrank from Maori hunting, as shown from bones found in middens.  But unlike the moa, a few takahe survived in the harsh, wet environment of the Murchison and Stuart Mountains, safe from human killing.</p> <p>While isolation saved them, survival was still threatened from heavy grazing of their tussock grass habitat by introduced deer, and nest and chick predation by stoats.</p> <p>Takahe are now protected in the wilderness of Fiordland National Park, which is New Zealand's largest national park, and a World Heritage area.</p> <p>However, takahe have not made a comeback in the natural habitat in which they were found in 1948.</p> <p>The population dwindled from 400 to 118 birds in 1982.
