Woehler, compiler Editorial This is the second Tasmanian Bird Report in which we publish a report on ‘The state of Tasmania’s birds’. This, the 2015–16 edition, updates the status of terrestrial birds, as well as including three case studies and giving an overview of the status of a group of twenty waterfowl. It has been a time-consuming undertaking by all involved, Mike Newman and Nick Ramshaw in particular. To make regular reports that track populations of the State’s birds, reliable population records are needed. Anyone who can begin surveys can participate through Birdata (http://birdata.birdlife.org.au/) where new data is entered and feedback is given. Warren and Sue Jones have written an article that gives a snapshot of the birdlife of the Peter Murrell Reserves at Kingston, Tasmania, while Mike Newman has contributed two papers dealing with the health of woodlands and ways to evaluate the health of remnant woodland. Other contributions come from around the state: the north-west, north and east, as well as the south. This material appears as short essays and as segments in ‘Oddities of behaviour and occurrence’. Time pressure has precluded compilation of tables for the summer and winter wader counts for 2017. These will appear in the next edition of the Tasmanian Bird Report. The Bird Report is a vehicle for publication of papers by researchers and amateur bird- watchers from around the state, as well as for releasing reports that have been completed for various interests: governmental, NGO and commercial. We strongly encourage members and researchers to submit papers. Wynne Webber Editor Tasmanian Bird Report State of Tasmania’s birds, 2015–16 Mike Newman, Nick Ramshaw, Sue Drake, Eric J.

Checklist of the birds of New Zealand, Norfolk and Macquarie Islands, and the Ross Dependency, Antarctica. 4th edition. Wellington, Te Papa Press and Ornithological Society of New Zealand. Pages 275, 279, 301-302 & 305-306. Order PASSERIFORMES: Passerine (Perching) Birds See Christidis & Boles (2008) for a review of recent studies relevant to the higher-level systematics of the passerine birds. Suborder PASSERES (or POLYMYODI): Oscines (Songbirds) The arrangement of songbirds in the 1970 Checklist (Checklist Committee 1970) was based on the premise that the species endemic to the Australasian region were derived directly from Eurasian groups and belonged in Old World families (e.g. Gerygone and Petroica in Muscicapidae). The 1990 Checklist (Checklist Committee 1990) followed the Australian lead in allocating various native songbirds to their own Australasian families (e.g. Gerygone to Acanthizidae, and Petroica to Eopsaltriidae), but the sequence was still based largely on the old Peters-Mayr arrangement. Since the late 1980s, when the 1990 Checklist was finalised, evidence from molecular biology, especially DNA studies, has shown that most of the Australian and New Zealand endemic songbirds are the product of a major Australasian radiation parallel to the radiation of songbirds in Eurasia and elsewhere. Many superficial morphological and ecological similarities between Australasian and Eurasian songbirds are the result of convergent evolution. Sibley & Ahlquist (1985, 1990) and Sibley et al. (1988) recognised a division of the songbirds into two groups which were called Corvida and Passerida (Sibley & Ahlquist 1990).

  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

The general slope is to the south especially of the eastern half, which corresponds to the drainage being effected by south flowing streams. The western boundary is represented by the West Coast Range which presents a steep face to the west.

    Field Guides Tour Report Australia Part 2 2019 Oct 22, 2019 to Nov 11, 2019 John Coons & Doug Gochfeld For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. Water is a precious resource in the Australian deserts, so watering holes like this one near Georgetown are incredible places for concentrating wildlife. Two of our most bird diverse excursions were on our mornings in this region. Photo by guide Doug Gochfeld. Australia. A voyage to the land of Oz is guaranteed to be filled with novelty and wonder, regardless of whether we’ve been to the country previously. This was true for our group this year, with everyone coming away awed and excited by any number of a litany of great experiences, whether they had already been in the country for three weeks or were beginning their Aussie journey in Darwin. Given the far-flung locales we visit, this itinerary often provides the full spectrum of weather, and this year that was true to the extreme. The drought which had gripped much of Australia for months on end was still in full effect upon our arrival at Darwin in the steamy Top End, and Georgetown was equally hot, though about as dry as Darwin was humid. The warmth persisted along the Queensland coast in Cairns, while weather on the Atherton Tablelands and at Lamington National Park was mild and quite pleasant, a prelude to the pendulum swinging the other way. During our final hours below O’Reilly’s, a system came through bringing with it strong winds (and a brush fire warning that unfortunately turned out all too prescient).

    Impact of sea level rise on coastal natural values in Tasmania JUNE 2016 Department of Primary Industries, Parks, Water and Environment Acknowledgements Thanks to the support we received in particular from Clarissa Murphy who gave six months as a volunteer in the first phase of the sea level rise risk assessment work. We also had considerable technical input from a range of people on various aspects of the work, including Hans and Annie Wapstra, Richard Schahinger, Tim Rudman, John Church, and Anni McCuaig. We acknowledge the hard work over a number of years from the Sea Level Rise Impacts Working Group: Oberon Carter, Louise Gilfedder, Felicity Faulkner, Lynne Sparrow (DPIPWE), Eric Woehler (BirdLife Tasmania) and Chris Sharples (University of Tasmania). This report was compiled by Oberon Carter, Felicity Faulkner, Louise Gilfedder and Peter Voller from the Natural Values Conservation Branch.
