We defined robust and repeatable survey protocols for locating the night parrot that are applicable to other parts of its possible range. Our detection methods were used to discover multiple populations of night parrots in central Western Australia, and that region is now thought to be the species’ stronghold. We also confirmed the suspected presence of night parrots in Diamantina National Park in Queensland. LEFT: Night parrot roosting habitat.

  • A8 Targeted Night Parrot Fauna Assessment

One area under consideration is in the west of the Robe Valley in the vicinity of the mining areas of Mesa A and Warramboo (survey area), located approximately 50 km west of Pannawonica. Key components of the pre-feasibility and feasibility studies being undertaken are environmental surveys which are required to inform the environmental assessment process for the potential development of the survey area. Due to the recent publication of the Interim guideline for preliminary surveys of Night Parrot (Pezoporus occidentalis) (Department of Parks and Wildlife 2017) and to ensure all fauna surveys meet current guidelines, Astron was commissioned to undertake a targeted Night Parrot fauna survey in the survey area (Figure A.1, Attachment A). The possible occurrence of this Matters of National Environmental Significance species within the survey area presents a potential management issue to ground disturbance activities for the development of the Mesa A Hub. In order to improve understanding of the potential for Night Parrot occurrence, habitat utilisation and resident population estimates, a more intensive survey was required within the survey area. 2 Scope of Work The scope of work was to conduct a targeted Night Parrot fauna survey within the survey area in accordance with the scope of works provided by Rio Tinto (dated 17/07/2017), regulatory guidelines (Department of Parks and Wildlife 2017) and industry best practice.

    Interim Recovery Plan No. 4 INTERIM RECOVERY PLAN NO. 4 NIGHT PARROT (PEZOPORUS OCCIDENTALIS) INTERIM RECOVERY PLAN FOR WESTERN AUSTRALIA 1996 to 1998 by John Blyth March 1996 Department of Conservation and Land Management Western Australian Threatened Species and Communities Unit: WA Wildlife Research Centre, PO Box 51, Wanneroo, WA 6065 Interim Recovery Plan No. 4 FOREWORD Interim Recovery Plans (IRPs) are developed within the framework laid down in Department of Conservation and Land Management (CALM) Policy Statements Nos 44 and 50. Where urgency and/or lack of information mean that a full Recovery Plan can not be prepared, IRPs outline the recovery actions required urgently to address those threatening processes most affecting the ongoing survival and begin the recovery process of threatened taxa or ecological communities. CALM is committed to ensuring that Critically Endangered taxa are conserved, through the preparation and implementation of Recovery Plans or Interim Recovery Plans and ensuring that conservation action commences as soon as possible and always within one year of endorsement of that rank by the Minister. This IRP was approved by the Director of Nature Conservation on 21 March, 1996. Approved IRPs are subject to modification as dictated by new findings, changes in status of the taxon or ecological community and the completion of recovery actions. The provision of funds identified in this Interim Recovery Plan is dependent on budgetary and other constraints affecting CALM, as well as the need to address other priorities. Information in this IRP was accurate at 14 March, 1996. ii Interim Recovery Plan No. 4 CONTENTS FOREWORD ........................................................................................................................... iii SUMMARY .............................................................................................................................

  • Parrot World's Endangered Heavyweight Faces New Threat 13 June 2019
    Parrot world's endangered heavyweight faces new threat 13 June 2019 extinct. An intense, decades-long conservation effort has seen kakapo numbers slowly rise from a low of about 50 in 1990, and earlier this year there was hope the species was turning the corner. The breeding programme resulted in 249 eggs laid, fuelling expectations at least 75 chicks would survive the year, more than double the previous record. But Auckland Zoo veterinarian James Chatterton said efforts were now focussed on saving the birds infected by aspergillosis, which before this year was known to have killed just one kakapo. The setback comes just weeks after scientists hailed a bumper breeding season for the flightless, nocturnal bird, which was once thought to be extinct An unprecedented disease outbreak has pushed the critically endangered kakapo, the world's fattest parrot, closer to extinction, New Zealand scientists said Thursday. One of the last kakapo populations on remote Codfish Island has been hit with a fungal respiratory disease called aspergillosis, the Department of Conservation (DOC) said. It said 36 of the parrots were receiving treatment The kakapo - 'night parrot' in Maori - only mates every and seven had died, including two adults—a huge two to four years when New Zealand's native rimu trees are full of fruit loss for a species which has less than 150 fully grown birds left. "Aspergillosis is having a devastating impact on "It's an unprecedented threat and we're working kakapo," the DOC said in a statement Thursday. really hard to understand why it's happened this year," he told TVNZ.

Email: [email protected] Abstract. Until recently, the only descriptions of Night Parrot Pezoporus occidentalis vocalisations were anecdotal reports from observers in the late 19th and early 20th centuries. The 2013 discovery of an extant population of Night Parrots in western Queensland led to the first contemporary descriptions, and further calls were described following the 2017 discovery of Night Parrots at a site in central Western Australia. Ongoing field studies have shown that the species has a complex repertoire and, although there are some similarities in vocalisations between sites, there is much spatial and temporal variation. It is likely that call recognition will be the primary means of detection for this cryptic species, underscoring the importance of cataloguing vocalisations across the species’ range.

They daz- zle the beholder with every color in the rainbow (figure 3). They range in size from tiny pygmy parrots weighing just over 10 grams to giant macaws weighing over a kilogram. They consume a wide variety of foods, including fruit, seeds, nectar, insects, and in a few cases, flesh. They produce large repertoires of sounds, ranging from grating squawks to cheery whistles to, more rarely, long melodious songs. They inhabit a broad array of habitats, from lowland tropical rainforest to high-altitude tundra to desert scrubland to urban jungle. They range over every continent but Antarctica, and inhabit some of the most far-flung islands on the planet. They include some of the most endangered species on Earth and some of the most rapidly expanding and aggressive invaders of human-altered landscapes. Increasingly, research into the lives of wild parrots is revealing that they exhibit a corresponding variety of mating systems, communication signals, social organizations, mental capacities, and life spans.

They rely on trees, plants and other animals for food, shelter and their basic needs. An incredible range of birds is found in New Zealand: from large, flightless, ground-dwelling birds like the kākāpō and kiwi, to tiny, delicate songbirds like the grey warbler/ riroriro. Both endemic and native birds are an important part of balanced, healthy ecosystems. They pollinate plants and disperse their seeds, spread nutrients, and keep populations of insects and other living things stable. In Te Ao Māori, endemic and native birds enhance the mauri (life force/vitality) of an area and are part of whakapapa links (connections and ancestry). For more information, classroom activities and outdoor investigations about birds that can be found in your school grounds, backyard and local park or reserve, check out the ‘Experiencing birds in your green space’ resource – www.doc.govt.nz/education-experiencingbirds.
