Carnaby’s Black Cockatoo is an endangered species which has undergone a dramatic decline in range and abundance southwestern Australia. Between October 2009 March 2010 the was subjected to possible outbreak of disease one its major breeding areas exposed extremely hot day severe localized hail storm. In addition, collisions with motor vehicles are becoming increasing threat species. All these stochastic events resulted many fatalities. Species such as form large flocks particularly...

Efforts to euthanise stranded cetaceans remain highly variable in their outcomes, with few field tested operational procedures available. This study sought validate the efficacy of using modern firearms technology small (<6m length) cetaceans. Post-mortem evidence was gathered from standardised shooting cetacean cadavers (n = 10), representing six species, .30 caliber (7.62mm) and blunt solid copper-alloy non-deforming projectiles, southwestern Australia. The species studied were Risso’s...

Context Extinction rates for Australian species are a major concern that requires new approaches to conserving species. Sustainable collecting, which is taking individuals of from the wild without affecting overall population numbers, has emerged as one method placing value on endangered species, can help protect them extinction. Aims We evaluated case study sustainably collect an cockatoo Carnaby’s (Zanda latirostris). Methods A 3-year program was conducted where eggs or nestlings were...

SummaryThe size and health of hollow-bearing eucalypts successfully used by four species parrot one cockatoo in the south-west Western Australia are described. The estimated age these nest trees based on known growth rates is given ranged from 73 years to over 1300 years. lowest average recorded for any was 275 years, 446 species. In view current timber production strategies management policies remnants native vegetation there a real possibility that hollows may be limited supply some areas...

A method for the safe and effective euthanasia of large beached humpback whales using explosives is described. Five recent case studies involving live stranded measuring 9.1–12.7m are described to show how was applied, capacity deal with varying conditions encountered when dealing baleen whales. Issues relating wider application this other species whale odontocete discussed along key safety implications use method.

Captive breeding is an important tool for amphibian conservation despite high economic costs and deleterious genetic effects of sustained captivity unavoidably small colony sizes. Integration biobanking assisted reproductive technologies (ARTs) could provide solutions to these challenges, but rarely used due lack recognition the potential benefits clear policy direction. Here we present compelling arguments integrate ARTs into captive programs using modelled populations two Australian...

Of the five species of black cockatoo in genus Calyptorhynchus, those with red tail bands (Red-tailed Black Cockatoo and Glossy Cockatoo) lay clutches only one egg white or yellow (Carnaby's Cockatoo, Baudin's Yellow-tailed usually two. The breeding endangered Carnaby's has been studied from 1969 to 2012 at a number localities throughout its range south-western Australia within region largely cleared for agriculture. When raising nestlings feeds on seeds native vegetation, there was strong...

Context Carnaby’s Cockatoo is an endangered species and the subject of a recovery plan. Aims Our study examined movements adult fledgling Cockatoos from 11 breeding populations in southwestern Australia to establish where cockatoos spent non-breeding season (February–May) sub-adult life-stage. Methods Data were collected on point-to-point re-sightings recoveries individually marked with patagial tags or leg bands. Sites mostly located wheatbelt Western Australia. Distribution patterns...

Abstract Aim We examined how the threatened and endemic white‐tailed black cockatoos of Western Australia have responded genetically to recent comprehensive habitat loss with ultimate aim identifying units for conservation. assessed population structure, connectivity genetic diversity at spatial temporal scales Calyptorhynchus baudinii C. latirostris , which undergone dramatic declines. Genetic comparisons pre‐ post‐population decline were carried out by including historical samples dating...

The conservation of highly mobile species presents challenges to managers for assessment threats survival, given the difficulties in locating and observing such species. Here we evaluate satellite telemetry, DNA faecal metabarcoding traditional field observations as three complementary techniques acquire critical management information an endangered species, Carnaby's Cockatoo Calyptorhynchus latirostris . Satellite telemetry 23 birds resulted 6026 location fixes accurate within 500 m,...

This study examined the metabolic ecology of six cockatoo taxa endemic to south-west Western Australia. As availability food is one factor that may influence abundance and distribution these cockatoos, we document here their baseline energy requirements feeding patterns. Evaporative waterloss was also measured as this correlate with aridity species’ environment. Basal rate significantly lower at 0.62 ± 0.13 mL O2 g–1 h–1 for inland red-tailed black than 1.11 0.16 forest cockatoo, but there...

The management of overabundant urban fauna is a contentious issue worldwide, particularly for populations white-tailed deer (Odocoileus virginianus) in North America and kangaroos (Macropus spp.) Australia. To be successful, programs such settings must cost-effective, humane, publicly acceptable. Here, we describe the fenced, population western grey (M. fuliginosus) southwestern Australia, with an estimated density 189 kangaroos/km2. After period >12 months solicited public involvement by...

Human-wildlife conflicts around the loss and use of habitat are common reasons for species being listed as threatened. In order to reduce such it is important have a clear understanding resource requirements threatened environmental factors that influence availability continued supply those resources. The Banksia cones temporal patterns their by Carnaby ‘s Black-Cockatoo (Calyptorhynchus latirostris), was measured bi-monthly in proteaceous woodlands Swan Coastal Plain, south-western...

Abstract It is sometimes necessary to restrain kangaroos ( Macropus spp) for veterinary treatment or in the course of scientific research, but associated stresses may induce capture myopathy wild kangaroos. Judicious use injectable sedatives can reduce risk myopathy. Zoletil®, a proprietary mixture tiletamine and zolazepam, reported have wide safety margin, small dose volume, be quick acting range animals. We investigated dose-response relationship Zoletil® 26 western grey (Macropus...

ABSTRACT The collection of baseline health data is an essential component endangered species conservation program. As for many wildlife species, there are minimal available wild populations the Carnaby’s cockatoo (Zanda latirostris). In this study, 426 nestlings were sampled from nine breeding sites throughout range over 11-year period. addition to a physical examination, samples collected test hematologic and biochemical parameters, psittacine beak feather disease virus (BFDV), avian...

Australian marsupials are thought to be particularly vulnerable pathologic impacts of Toxoplasma gondii, and they may similarly affected by Neospora caninum. Pathology due either organism could expressed as reduced female reproductive performance. We studied adult western grey kangaroos (Macropus fuliginosus ocydromus) from suburban Perth, Western Australia, between May 2006 October 2008. used indirect fluorescent antibody tests look for evidence exposure T. gondii N. caninum in M. ocydromus...
