Abstract:
AbstractSeveral waterbird species prey on fishes, and usually use only one sensory mode to detect this prey: herons hunt visually guided, whereas ibises mostly search tactilely guided. I report herein events in which a heron and an ibis caught and released a poisonous fish at a mudflat in southeastern Australia. A Great Egret (Ardea alba) that targeted small gerreid fishes caught and immediately released the very toxic pufferfish Tetractenos hamiltoni, with bill washing and discomfort movements afterwards. Two Australian White Ibises (Threskiornis molucca) that probed for bottom-dwelling fishes and crabs caught and handled these pufferfishes for about 60 s, before releasing them. Next, the birds dipped the bill in the water and resumed hunting. Pufferfishes are rarely preyed on by birds, but an Australian bird that feeds on this fish type is the Silver Gull (Chroicocephalus novaehollandiae), which eats the pufferfish Torquigener pleurogramma when it is nontoxic or less harmful.

Abstract:
There are 93 species of Australian waterbirds, predominantly dependent on freshwater, inland saline or estuarine ecosystems. They include diverse species predominantly from six major groups: grebes (Podicipediformes); ducks, geese and swans (Anseriformes); pelicans and cormorants (Pelecaniformes); egrets, ibises, spoonbills (Ciconniiformes); cranes, rails and crakes (Gruiiformes) and shorebirds (Charadriiformes). I analysed the content of 382 publications on Australian waterbirds in relation to life history and threats. There were 4.08 publications per species, with most publications biased towards the Anseriformes (6.95 publications per species). There were relatively few publications on Gruiformes (1.13 per species) or Podicipediformes (0.33 per species). There is reasonably good knowledge of distribution, abundance, diet and foraging and habitat use, but there were generally few examples of integration of these data into population modelling, a particularly useful tool for conservation of species. Significant gaps exist in the understanding of basic life history and movement patterns, critical for conservation; these are particularly accentuated for cryptic species. Opportunities exist to collection basic information, directed towards modelling population dynamics. As with most of the world’s organisms, habitat loss and degradation remain the major threat to waterbirds in Australia. The ongoing pressure on water resources and developments of estuaries continue to cause decline of waterbirds, exacerbated by secondary threats including climate change, disease, hunting, pollution and disturbance. Hunting continues to have an impact, but it is relatively poorly modelled, requiring more investment by governments charged with its management. Effective conservation of Australian waterbirds and their wetland habitats depends on mitigating habitat loss and degradation, primarily dependent on political will not knowledge.

Abstract:
The Australian White Ibis (Ibis) ( Threskiornis molucca) is one of three endemic Ibis species in Australia. In a short time frame beginning in the 1970s, this species has moved from inland waterways to urban centres along the eastern and southeastern seaboards, Darwin and the Western Australian southwest. Today Ibis are at home in cities across the country, where they thrive on the food waste, water resources and nesting sites supplied by humans. In this article, the authors focus on Sydney to argue that the physical and cultural inroads of Ibis, and the birds’ urban homeliness, are resignifying urban surfaces and the multispecies ecologies in which contemporary Australians operate. They explore how the very physical and sensory presence of Ibis disrupts the assumptions of many urban Australians, and visitors from overseas, that cities are human-centric or human-dominant, non-hybrid assemblages. They also introduce to this discussion of disrupted human expectations a cultural parallel, namely, the recent rise of Ibis in popular culture as an icon-in-the-making of the nation and as a totem of the modern Australian city itself. This trend exemplifies an avian-led revisualization of urban spaces, and is notable for its visual appeals to Ibis kitsch, and to working class or ‘bogan’ sensibilities that assert their place alongside cosmopolitan visions of being Australian. Sometimes kitsch Ibis imagery erupts across the urban landscape, as occurs with many Ibis murals. At other times it infiltrates daily life on clothing, on football club, university and business logos, as tattoos on people’s skin, and as words in daily idiom, confirmed by terms such as ‘picnic pirates’, ‘tip turkeys’ and ‘bin chickens’. The article uses a visual vignette methodology to chart Ibis moves into Sydney and the realms of representation alike, and thus to reveal how new zoöpolitical entanglements are being made in the 21st century.

Abstract:
Chlamydia psittaci is traditionally regarded as a globally distributed avian pathogen that can cause zoonotic spill-over. Molecular research has identified an extended global host range and significant genetic diversity. However, Australia has reported a reduced host range (avian, horse, and human) with a dominance of clonal strains, denoted ST24. To better understand the widespread of this strain type in Australia, multilocus sequence typing (MLST) and ompA genotyping were applied on samples from a range of hosts (avian, equine, marsupial, and bovine) from Australia. MLST confirms that clonal ST24 strains dominate infections of Australian psittacine and equine hosts (82/88; 93.18%). However, this study also found novel hosts (Australian white ibis, King parrots, racing pigeon, bovine, and a wallaby) and demonstrated that strain diversity does exist in Australia. The discovery of a C. psittaci novel strain (ST306) in a novel host, the Western brush wallaby, is the first detection in a marsupial. Analysis of the results of this study applied a multidisciplinary approach regarding Chlamydia infections, equine infectious disease, ecology, and One Health. Recommendations include an update for the descriptive framework of C. psittaci disease and cell biology work to inform pathogenicity and complement molecular epidemiology.

Abstract:
The Australian white ibis (Threskiornis molucca) is considered to be an urban pest along the east coast of Australia. The non-specific diet and broad habitat requirements of ibis have facilitated their successful exploitation of the urban environment. Ibis are considered a pest because they pose a threat to aircraft safety, scavenge food at waste-management sites, cafés and parks, and compete with other native species for food and habitat. This study assesses a new ibis-management technique, the application of ‘egg-oil’ to suppress hatching. On other species, egg-oiling has been shown to be environmentally safe and socially preferable to culling adult birds. Approximately 5 mL of food-grade canola oil was sprayed upon each egg, and both incubator and field trials were used to investigate the efficacy of this technique on ibis and to determine the optimal application time and frequency of egg-oil. Treatment eggs were given an application of oil during the 23-day incubation period either once per week, or once early (<7 days), mid (~14 days) or late (>18 days) incubation. All four treatments were observed to be 100% effective at preventing ibis eggs from hatching during the laboratory trial and more than 98% effective during the field trial. These results indicate that applying canola oil to ibis eggs once, at any time, during the 23-day incubation period is sufficient to prevent ibis eggs from hatching. The field trial also showed that 30% of ibis, across the four oiling treatments, continued to incubate the unviable eggs for up to 54 days longer than the normal incubation period. Given that ibis are multibrooded, raising up to three successful clutches in a breeding season, the increased time devoted to incubating oil-treated eggs could reduce the opportunity for multiple broods, compared with conventional egg destruction. The egg-oil technique offers an additional tool for land managers to conduct ibis reproduction control, which should reduce the amount of time required to conduct ibis management, consequently reducing the cost to land managers.

We observed a probable juvenile Australian White Ibis Threskiornis moluccus × Straw-necked Ibis T. spinicollis hybrid on the Lachlan River catchment, New South Wales, in November 2016. Photographs, combined with observations, demonstrate phenotypic characteristics of both these ibis species. The bird had a pattern on the wing similar to the Australian White Ibis but coloration on the body similar to the Straw-necked Ibis. To our knowledge, this is only the second report of a probable hybrid between these two species in the wild, and the first report documented with photographs

Abstract:
The genera of Australian Membracidae (Hemiptera) are revised. Thirty seven genera are recognised. A key to the genera and illustrations of representatives of most genera provide aids to identification. All known genera are described using morphological characters, some of which have not been employed previously for the Membracidae. The following genera and species are described as new: Bunyella, gen. nov., Matumuia, gen. nov., Matumuia laura, sp. nov., Neocanthuchus, gen. nov., Neocanthuchus barringtonensis, sp. nov., Neocanthuchus tropicus, sp. nov., Neosextius, gen. nov., Neosextius longinotum, sp. nov., Neosextius yanda, sp. nov., Protinotus, gen. nov., Rentzia, gen. nov., Rentzia gabana, sp. nov., Rentzia yarla, sp. nov., Rigula, gen. nov., Rigula calperum, sp. nov., Rigula naumanni, sp. nov., Rigula yalkula, sp. nov., Strzeleckia, gen. nov., Strzeleckia montanus, sp. nov., Undarella, gen. nov., Undarella pulleni, sp. nov., Undarella storeyi, sp. nov. and Yangupia, gen. nov. The previously described species Centrotypus occidentalis Goding is transferred to Yangupia, gen. nov.; Acanthuchus dromedarius Kirkaldy is transferred to Bunyella, gen. nov.; Otinotus doddi Distant is transferred to Protinotus, gen. nov. Evidence is now strong that the single species of the following genera: Xiphistes Stål, Centrotypus Stål, Ibiceps Buckton, and Leptocentrus Stål, reported to have come from Australia, were, in fact, collected in countries overseas. These genera should no longer be included in the Australian fauna. The origins, biology and distribution of the indigenous membracids are briefly discussed in the light of the current understanding of the group.

Abstract:
Context. In the Sydney region, the population of Australian white ibis has dramatically increased from rare observations in the 1950s to a breeding season peak of 8900 in 2008, resulting with human–wildlife conflicts. Within natural habitats across the eastern states, the ibis population has declined, yet within urban environments ibis have been lethally managed for over 30 years. However, limited ecological and no regional population data are available for the Sydney region. Aims. The present study of ibis in the Sydney region aims to (1) establish the abundance of the population during the breeding and non-breeding seasons, (2) determine whether the population is increasing, and (3) identify the importance of different foraging and roosting sites. Methods. Across the Sydney region, we surveyed 54 discrete sites for 2.5 years. At each site, we recorded the number of adult, juvenile and nestling ibis as well as the number of active nests. The 54 sites were grouped into 15 areas consisting of five landfills and 10 suburbs, which were assessed with ANOVA. Key results. The ibis population of the Sydney region doubled from a peak of 4200 in 2006 to 8900 in 2008. Seasonal fluctuations saw adults migrating in to the region to breed, and adults and juveniles dispersing following breeding. On average, 44% of the population was located foraging within landfills, whereas 80% of nesting activity occurred within ‘urban-natural’ habitats. Conclusions. Seasonal fluctuations indicated that the ibis population of Sydney is connected with the broader state and national population. Landfills provided an abundant foraging resource that supported extended breeding, including consistent nesting for a 19-month period. Implications. The present study indicated that any localised population management has consequences beyond the immediate or regional population and, consequently, regional management plans or actions need to consider the long-term status of the eastern states’ population. Urban conflicts need to be resolved with human education and a conservation agenda, preferably with the provision of refuge habitat where birds are not disturbed.
