The report and much of the data in it were collected and largely funded by volunteers. This is an extraordinary expression of concern for Australia’s birds and their habitats. Without such commitment, how are we to understand the state of our birds: which species and bird communities are truly in trouble, where to focus conservation efforts, whether conservation interventions are working?

  • Beak and Feather Disease Viru
    Fact sheet Beak and feather disease virus (BFDV) is the causative agent of psittacine beak and feather disease (PBFD), an endemic disease in Australia’s wild parrot populations. Descriptions of parrots with feather loss consistent with the disease date back to the late 1800s (Ashby 1907). The virus is believed to have originated in Australia sometime following the separation of the continent from Gondwanaland, with spread to other parts of the world with modern movement of parrots as pet and aviary species . It has the potential to impact on several endangered Australian and non-Australian parrot populations and is listed as a key threatening process by the Australian government. Of late, the virus also has been identified in various non-psittacine species . Beak and feather disease virus is a 14 to 16 nm non-enveloped icosahedral DNA virus belonging to the family Circoviridae. Formerly, it was believed that the circoviruses recovered from a diverse range of psittacines were all antigenically similar. Doubt was cast on this theory when a virus that appeared to be serologically and genetically different was isolated from cockatiels (Nymphicus hollandicus) (Shearer et al. 2008). More recent research appears to indicate that psittacine circoviruses can be divided into two species and multiple viral strains. Based on work by Varsani et al. (2011), BFDV contains 14 strains, while budgerigar circovirus (BCV), a newly defined species to date only found in budgerigars (Melopsittacus undulates), contains three strains. However, it is likely that this number will continue to increase as shown by the discovery of two new distinct BFDV lineages in orange-bellied parrots (Neophema chrysogaster) (Peters et al.

  • DIET of the EASTERN BRISTLEBIRD Dasyornis Brachypterus in NEW SOUTH WALES
    Corella, 2004, 28(3): 79-81 DIET OF THE EASTERN BRISTLEBIRD Dasyornis brachypterus IN NEW SOUTH WALES LINDA GIBSON1 and JACK BAKER2 'Australian Museum, 6 College Street, Sydney, New South Wales 2010 'Institute of Conservation Biology. Department of Biological Sciences, University of Wollongong, New South Wales 2522 Received: I October 2003 7 The diet of the Eastern Bristlebird Oasyomis brachypterus in New South Wales was determined from observations and an analysis of faeces, stomach and gut contents of 18 birds caught in or obtained from Booderee National Park, Jervis Bay and Barren Grounds Nature Reserve, New South Wales. The study showed these birds largely take mobile terrestrial invertebrate species, the majority of which are ants and beetles. There is some indication that plant material, especially seeds, are also part of the diet. Observations suggest that the diet is opportunistic and based on foraging behaviour of 'peck it and see'. INTRODUCTION STUDY AREA AND METHODS Dasyornis brachypterus The specimens used in this study were obtained from two sites. The rare Eastern Bristlebird ° ° (Passeriformes: Pardalotidae), is a small, semi-flightless, Booderee National Park, (35 08'S, l 50 45'E) a Commonwealth of Australia owned area that occupies most of the Bherwerre brownish bird inhabiting low, dense vegetation in coastal Peninsula, on the southern side of Jervis Bay, on the south coast and near coastal south-eastern Australia. It once occurred of New South Wales and Barren Grounds Nature Reserve (34°40'S, in an almost continuous distribution from southern l 50 °42'E) on the lllawarra plateau, west of Kiama, New South Queensland to western Victoria (Baker 1997).

  • 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.

    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).

S.DEBUS Division of Zoology, University of New England, Armidale, New South Wales 2351 E-mail: [email protected] Received:I3 January 2006 The breeding biology and behaviour of the Scarlet Robin Petroica multicolor and Eastern Yellow Robin Eopsaltria australis were studied at lmbota Nature Reserve, on the New England Tableland of New South Wales,in 200G-2002by colour-bandingand nest-monitoring.Yellow Robins nested low in shelteredpositions, in plants with small stem diameters(mostly saplings,live trees and shrubs),whereas Scarlet Robins nested high in exposed positions, in plants with large stem diameters (mostly live trees, dead branches or dead trees).Yellow Robin clutch size was two or three eggs (mean 2.2; n = 19). Incubationand nestling periods were 15-17 days and 11-12 days respectively(n = 6) for the Yellow Robin, and 16-18 days (n = 3) and 16 days (n = 1) respectivelyfor the ScarletRobin. Both specieswere multi-brooded,although only YellowRobins successfully raised a second brood. The post-fledging dependence period lasted eight weeks for Yellow Robins, and six weeks for Scarlet Robins. The two robins appear to differ in their susceptibilityto nest predation, with corresponding differences in anti-predator strategies.
