SOUTH ISLAND SADDLEBACK RECOVERY PLAN (Philesturnus Carunculatus Carunculatus )
THREATENED SPECIES RECOVERY PLAN SERIES NO.11 SOUTH ISLAND SADDLEBACK RECOVERY PLAN (Philesturnus carunculatus carunculatus ) Prepared by Andy Roberts (Southland Conservancy) for the Threatened Species Unit Threatened Species Unit Department of Conservation P.O. Box 10-420 Wellington New Zealand © 1994 ISSN 1170-3806 ISBN 0-478-01481-9 Key words: South Island saddleback, Philesturnus carunculatus carunculatus, recovery plan ABSTRACT South Island saddlebacks (tieke) were widely distributed over the South and Stewart Islands in the 19th century. Their rapid decline was documented during the latter 19th century. Following a rodent invasion on their sole remaining island habitat South Island saddlebacks were under threat of immediate extinction. This was thwarted by prompt translocations of remaining birds to nearby predator-free islands. This plan outlines conservation goals and suggests options for continuing the recovery of this subspecies. Recovery is to be achieved through a programme of island habitat restoration and saddleback translocations. Eradication of rodents and weka is promoted by this plan, in some instances this plan suggests that discussions be held with the local Iwi to determine the appropriateness of these eradications. Saddlebacks are to be introduced or re-introduced to a number of islands around the South Island coast. When recovery has been achieved South Island saddleback populations may be established on up to 26 islands with a total of about 4000 individuals. At this population level they will not be ranked as threatened, but be classified as rare and no longer requiring a programme of on-going intensive conservation management. Recovery management proposed in this plan will be undertaken jointly by Department of Conservation staff, Iwi representatives and members of the public. -

Dodo' Award Title for Record Period with No New Named Endangered Species by Shirley Gregory
http://www.associatedcontent.com/article/358072/conservation_group_awards_interior.html Conservation Group Awards Interior Secretary 'Dodo' Award Title for Record Period with No New Named Endangered Species by Shirley Gregory By not placing a single plant or animal on the federal list of endangered species since his confirmation, U.S. Secretary of Interior Dirk Kempthorne has earned the first-ever "Rubber Dodo Award," according to news from the Center for Biological Diversity. Kempthorne has not listed a single species as endangered during the 472 days he has served as secretary, the center said, thereby passing the previous record held by former Interior Secretary James Watt, who placed no plants or animals on the endangered species list for 376 days during his term between 1981 and 1982. "Kempthorne is eminently deserving of the first annual Rubber Dodo award," said Kieran Suckling, policy director for the center, which established the award. "His refusal to protect a single imperiled species in more than 15 months gives him the worst record of any interior secretary in the history of the Endangered Species Act. His policies should go the way of the dodo as soon as possible." The award is named for the dodo bird, a three-foot-tall, flightless bird discovered on the uninhabited island of Mauritius by Dutch sailors in 1598. Within less than a century, the bird had been wiped out -- hunted by humans and other animals it had before never encountered nor developed a natural fear of. "Political appointees like Kempthorne come and go, but extinction is forever," Suckling said. "No politician has the right to destroy the future of an endangered species." As of July, according to a report by the Washington Post, only 60 species have been added to the Endangered Species list during the George W. -

The Distribution and Current Status of New Zealand Saddleback Philesturnus Carunculatus
Bird Conservation International (2003) 13:79–95. BirdLife International 2003 DOI: 10.1017/S0959270903003083 Printed in the United Kingdom The distribution and current status of New Zealand Saddleback Philesturnus carunculatus SCOTT HOOSON and IAN G. JAMIESON Department of Zoology, University of Otago, P.O. Box 56, Dunedin, New Zealand Summary This paper reviews and updates the distribution and status of two geographically distinct subspecies of New Zealand Saddleback Philesturnus carunculatus, a New Zealand forest passerine that is highly susceptible to predation by introduced mammals such as stoats and rats. The recovery of the North Island and South Island saddleback populations has been rapid since translocations to offshore islands free of exotic predators began in 1964, when both subspecies were on the brink of extinction. South Island saddlebacks have gone from a remnant population of 36 birds on one island to over 1,200 birds spread among 15 island populations, with the present capacity to increase to a maximum of 2,500 birds. We recommend that South Island saddleback be listed under the IUCN category of Near Threatened, although vigilance on islands for invading predators and their subsequent rapid eradication is still required. North Island saddlebacks have gone from a remnant population of 500 birds on one island to over 6,000 on 12 islands with the capacity to increase to over 19,000 individuals. We recommend that this subspecies be downgraded to the IUCN category of Least Concern. The factors that limited the early recovery of saddlebacks are now of less significance with recent advances in predator eradication techniques allowing translocations to large islands that were formerly unsuitable. -

According to Dictionary
Extinction: The Parrots We’ve Lost By Desi Milpacher The definition of extinction is “the act or process of becoming extinct; a coming to an end or dying out: the extinction of a species.” Once extinction has been determined, there is usually no chance of a species recurring in a given ecosystem. In mankind’s active history of exploration, exploitation and settlement of new worlds, there has been much loss of natural resources. Parrots have suffered tremendously in this, with over twenty species having been permanently lost. And there are many more that are teetering on the edge, towards the interminable abyss. In this article we find out what happened to these lost treasures, learn which ones are currently being lost, and why this is important to our world. The Old and New Worlds and Their Lost Parrots Little is known of the natural history of most of the world’s extinct parrots, mainly because they disappeared before in-depth studies were conducted on them. It is generally believed, save the Central American macaws which were least known, that most fed on diets similar to today’s parrots (leaves, blossoms, seeds, nuts and fruits), frequented heavy forested areas and nested mainly in tree cavities. A number could not fly well, or were exceptionally tame, leading to their easy capture. Nearly all of these natural treasures vanished between the 18th and early 20th centuries, and the main reason for their loss was overhunting. Some lesser causes included egg collecting (popular with naturalists in the 19th century), diseases (introduced or endemic), drought, natural disasters, predation by introduced species, and habitat alternation. -
A Synopsis of the Pre-Human Avifauna of the Mascarene Islands
– 195 – Paleornithological Research 2013 Proceed. 8th Inter nat. Meeting Society of Avian Paleontology and Evolution Ursula B. Göhlich & Andreas Kroh (Eds) A synopsis of the pre-human avifauna of the Mascarene Islands JULIAN P. HUME Bird Group, Department of Life Sciences, The Natural History Museum, Tring, UK Abstract — The isolated Mascarene Islands of Mauritius, Réunion and Rodrigues are situated in the south- western Indian Ocean. All are volcanic in origin and have never been connected to each other or any other land mass. Despite their comparatively close proximity to each other, each island differs topographically and the islands have generally distinct avifaunas. The Mascarenes remained pristine until recently, resulting in some documentation of their ecology being made before they rapidly suffered severe degradation by humans. The first major fossil discoveries were made in 1865 on Mauritius and on Rodrigues and in the late 20th century on Réunion. However, for both Mauritius and Rodrigues, the documented fossil record initially was biased toward larger, non-passerine bird species, especially the dodo Raphus cucullatus and solitaire Pezophaps solitaria. This paper provides a synopsis of the fossil Mascarene avifauna, which demonstrates that it was more diverse than previously realised. Therefore, as the islands have suffered severe anthropogenic changes and the fossil record is far from complete, any conclusions based on present avian biogeography must be viewed with caution.

Distributions of New Zealand Birds on Real and Virtual Islands
JARED M. DIAMOND 37 Department of Physiology, University of California Medical School, Los Angeles, California 90024, USA DISTRIBUTIONS OF NEW ZEALAND BIRDS ON REAL AND VIRTUAL ISLANDS Summary: This paper considers how habitat geometry affects New Zealand bird distributions on land-bridge islands, oceanic islands, and forest patches. The data base consists of distributions of 60 native land and freshwater bird species on 31 islands. A theoretical section examines how species incidences should vary with factors such as population density, island area, and dispersal ability, in two cases: immigration possible or impossible. New Zealand bird species are divided into water-crossers and non-crossers on the basis of six types of evidence. Overwater colonists of New Zealand from Australia tend to evolve into non-crossers through becoming flightless or else acquiring a fear of flying over water. The number of land-bridge islands occupied per species increases with abundance and is greater for water-crossers than for non-crossers, as expected theoretically. Non-crossers are virtually restricted to large land-bridge islands. The ability to occupy small islands correlates with abundance. Some absences of species from particular islands are due to man- caused extinctions, unfulfilled habitat requirements, or lack of foster hosts. However, many absences have no such explanation and simply represent extinctions that could not be (or have not yet been) reversed by immigrations. Extinctions of native forest species due to forest fragmentation on Banks Peninsula have especially befallen non-crossers, uncommon species, and species with large area requirements. In forest fragments throughout New Zealand the distributions and area requirements of species reflect their population density and dispersal ability. -
