Nansei Islands Biological Diversity Evaluation Project Report 1 Chapter 1
Introduction WWF Japan’s involvement with the Nansei Islands can be traced back to a request in 1982 by Prince Phillip, Duke of Edinburgh. The “World Conservation Strategy”, which was drafted at the time through a collaborative effort by the WWF’s network, the International Union for Conservation of Nature (IUCN), and the United Nations Environment Programme (UNEP), posed the notion that the problems affecting environments were problems that had global implications. Furthermore, the findings presented offered information on precious environments extant throughout the globe and where they were distributed, thereby providing an impetus for people to think about issues relevant to humankind’s harmonious existence with the rest of nature. One of the precious natural environments for Japan given in the “World Conservation Strategy” was the Nansei Islands. The Duke of Edinburgh, who was the President of the WWF at the time (now President Emeritus), naturally sought to promote acts of conservation by those who could see them through most effectively, i.e. pertinent conservation parties in the area, a mandate which naturally fell on the shoulders of WWF Japan with regard to nature conservation activities concerning the Nansei Islands. This marked the beginning of the Nansei Islands initiative of WWF Japan, and ever since, WWF Japan has not only consistently performed globally-relevant environmental studies of particular areas within the Nansei Islands during the 1980’s and 1990’s, but has put pressure on the national and local governments to use the findings of those studies in public policy. Unfortunately, like many other places throughout the world, the deterioration of the natural environments in the Nansei Islands has yet to stop. -
A Classification of the Rallidae
A CLASSIFICATION OF THE RALLIDAE STARRY L. OLSON HE family Rallidae, containing over 150 living or recently extinct species T and having one of the widest distributions of any family of terrestrial vertebrates, has, in proportion to its size and interest, received less study than perhaps any other major group of birds. The only two attempts at a classifi- cation of all of the recent rallid genera are those of Sharpe (1894) and Peters (1934). Although each of these lists has some merit, neither is satisfactory in reflecting relationships between the genera and both often separate closely related groups. In the past, no attempt has been made to identify the more primitive members of the Rallidae or to illuminate evolutionary trends in the family. Lists almost invariably begin with the genus Rdus which is actually one of the most specialized genera of the family and does not represent an ancestral or primitive stock. One of the difficulties of rallid taxonomy arises from the relative homo- geneity of the family, rails for the most part being rather generalized birds with few groups having morphological modifications that clearly define them. As a consequence, particularly well-marked genera have been elevated to subfamily rank on the basis of characters that in more diverse families would not be considered as significant. Another weakness of former classifications of the family arose from what Mayr (194933) referred to as the “instability of the morphology of rails.” This “instability of morphology,” while seeming to belie what I have just said about homogeneity, refers only to the characteristics associated with flightlessness-a condition that appears with great regularity in island rails and which has evolved many times. -

Box 1120, Alice Springs, NT, 0871 Australia 2 Office of Environment and Heritage, P.O. Box 1967, Hurstville, NSW, 2220 Australia ORNITHOLOGICAL Abstract The Lord Howe Woodhen (Hypotaenidia sylvestris) is endemic to Lord Howe Island off the mid-east coast of Australia and came perilously close to extinc- SCIENCE tion as a result of hunting pressure and introduced predators. A recovery program was © The Ornithological Society implemented in the 1970s to reverse the decline of the species through eradicating of Japan 2019 introduced predators (pigs, cats and goats) and augmenting the population through an in situ captive-breeding program. In 1980, three wild breeding pairs were taken into captivity from Mount Gower. Over the four years of the captive-breeding program, 76 chicks were produced from the original founders and their progeny and an additional four chicks were artificially reared from eggs collected from a wild pair. Almost all woodhens were liberated across four release sites, but only 13% of released birds were resighted and numbers increased at only one of these sites and then declined. A captive-bred female that was released into the lowlands paired with a wild male (which had been temporarily held in captivity) and bred prolifically, leading to rapid population growth in the lowlands. The subpopulation on Mount Gower increased fivefold in the decade following the captive-breeding program, despite the removal of the three breeding pairs (which were released elsewhere) and receiving no aug- mentation from the captive-breeding program. -
Okinawa Custom Tour 14Th – 17Th April, 2016
Okinawa Custom tour 14th – 17th April, 2016 Tour leader: Charley Hesse Report and photos by Charley Hesse. (All photos were taken on this tour) The endangered endemic Okinawa Rail is a ‘must see’ on the island (Charley Hesse) This short custom extension was run prior to the Taiwan set departure tour. We just visited the main island of Okinawa where we concentrated on the forested north of the island with the local name ‘Yambaru’. Our main targets were the endemic Okinawa Woodpecker & Okinawa Rail, the latter only described as recently as 1981. We saw both easily, but we were also happy to see the endemic Ryukyu Robin & Ryukyu Minivet and several Ryukyu endemic subspecies, including Japanese & Ryukyu Scops-Owls, Whistling Green-Pigeon and Japanese Wood-Pigeon. We enjoyed fantastic birding and some great night excursions on which we saw several owl species, woodcock, the rare Ryukyu long-furred rat and beautiful Akamata snake. Our lodge was perfectly located in the native forests with all the targets on our doorstep. We were lucky to have the lodge to ourselves and the very friendly and helpful staff cooked us some wonderful Japanese food. After cleaning up in the north, we birded our way back to the capital Naha, hitting several areas of rice paddies and mudflats on the way back. We saw several interesting species such as Ruddy-breasted Crake, Yellow Bittern plus the endangered East Asian endemic Black-faced Spoonbill. Tropical Birding www.tropicalbirding.com 1 14th April – Naha to Yambaru On arrival in Okinawa, we began our drive north. We left the concrete sprawl of Naha and drove along beautiful coasts towards the forested hills near Kunigami village, or its local name ‘Yambaru’. -

Three endemic bird species have been recovering since the 2007 within the species, Okinawa rail (Hypotaenidia okinawae), Oki- small Indian mongoose (Urva auropunctata) con- nawa woodpecker (Dendrocopos noguchii), and Oki- trolled area. The GAMM results showed that these nawa robin (Larvivora namiyei), are found only in the bird species were abundant in areas with fewer small Yambaru region of the northern part of Okinawa Indian mongooses and larger areas of hardwood Island. In order to conserve endemic species, it is forests. Thus, the mongoose had a negative impact important to determine the effect of alien species on not only on the flightless rails but also on the endemic species. We conducted playback surveys four woodpeckers and the robins. In recent years, most of times every three years from 2007 to 2016 to evaluate the old-growth forests have been designated as the recent distribution of these three forest-dwelling protected forests, and large-scale logging is no longer bird species during the breeding season. Then, the taking place in Yambaru. Eradication of the mongoose association between the numbers of detections of these is particularly important for the conservation of these three species with the invasive mongoose density and three endemic bird species. -

Evidence for Aviculture: Identifying Research Needs to Advance the Role of Ex Situ Bird Populations in Conservation Initiatives and Collection Planning
Review Evidence for Aviculture: Identifying Research Needs to Advance the Role of Ex Situ Bird Populations in Conservation Initiatives and Collection Planning Paul Rose 1,2 1 Centre for Research in Animal Behaviour, Psychology, University of Exeter, Perry Road, Exeter, Devon EX4 4QG, UK; [email protected] or [email protected] 2 WWT, Slimbridge Wetland Centre, Slimbridge, Gloucestershire GL2 7BT, UK Simple Summary: Birds of a whole range of species are housed in zoological collections globally; they are some of the most frequently seen of species in animal populations kept under human care. Research output on birds can provide valuable information on how to advance husbandry and care for particular species, which may further feed into conservation planning. Linking birds housed in human care to those in the wild adds value to these zoo-housed populations; this paper provides areas of research that could be conducted to add value to these zoo-housed birds and suggests increasing the conservation focus and conservation relevance of birds housed by humans. Abstract: Birds are the most speciose of all taxonomic groups currently housed in zoos, but this species diversity is not always matched by their inclusion in research output in the peer-reviewed literature. This large and diverse captive population is an excellent tool for research investigation, the findings of which can be relevant to conservation and population sustainability aims. The One Plan Approach to conservation aims to foster tangible conservation relevance of ex situ populations to those animals living in situ.

Protection and Recovery Program for the Okinawa Rail (Gallirallus Okinawae)
Protection and Recovery Program for the Okinawa Rail (Gallirallus okinawae) November 19, 2004 Ministry of Education, Culture, Sports, Science and Technology Ministry of Agriculture, Forestry and Fisheries Ministry of Land, Infrastructure, Transport and Tourism Ministry of the Environment I. Objectives of the Program The Okinawa rail (Gallirallus okinawae) is a bird in the family Rallidae, first described as a new species in 1981. It is found only in the northern part of Okinawa Island. Current threats to its survival include predation by feral cats; rapid shrinking of the species range, likely due to the mongoose invasion; shrinking habitat due to land development; death or injury caused by motor vehicles; and adverse effects associated with improvident human interactions with the species, whether for observations or photographing of individuals. The objectives of this program is to ensure the stable survival of the bird in a natural state by clarifying the status of the species; maintaining and improving the environments necessary for the species; mitigating and removing factors that pose threats to the species; establishing artificial breeding techniques to safeguard against rapid declines in wild population; and exploring methods for reintroducing captive-bred animals. II. Program areas Okinawa Island in Okinawa Prefecture and captive breeding areas described in Item 3 of Section III below. III. Overview of the Program 1. Understanding the status of the species The following surveys will be undertaken to appropriately and effectively implement the program and to gather information on the species and its current situation. (1) Surveying and monitoring the status of the species The program will conduct surveys and undertake regular monitoring to gather information on the status of the population, including distributional range and habitat density.
