The occurrence of parasitism observed may be related to environmental features at landscape or nest-site scales. Such relationships have been assessed for the Brown-headed Cowbird (Molothrus ater) in the large forests of the northern hemisphere. Here, we present a study conducted on the Shiny Cowbird (M. bonariensis) in native forests of the southern hemisphere in Argentina. These forests are characterised as semi-open woodlands, with forest fragments of variable sizes immersed in native grasslands. We aimed to evaluate the effect of Shiny Cowbird brood parasitism on the breeding success of a native passerine, the Masked Gnatcatcher (Polioptila dumicola), and to assess the relationship of its occurrence with environmental features at landscape and nest-site scales. During three breeding seasons (2015–2018) we monitored 207 gnatcatcher nests of which 70 were parasitised. Brood parasitism was the cause of nest failure in 60% of the parasitised nests. In addition, breeding success measured by apparent nest success, egg survival, hatching success and nestling survival were significantly lower for parasitised nests than for non-parasitised nests. Brood parasitism occurrence was negatively associated with forest cover, where nests located in sites with less forest cover experienced a higher occurrence of parasitism than those with greater cover. As these native semi-open forests face a continuous decline, our results add to the evidence of negative impacts of deforestation.KEYWORDS: Argentinanesting biologyPolioptilidaereproductive parameterssouth temperate foresttalares AcknowledgmentsWe would like to thanks María Luisa Shaw for allowing us to conduct this study at the ‘Luis Chico’ ranch.

We aimed to evaluate whether urban intensification promotes ecomorphological changes in birds from a large city in Central Brazil. Analyses were performed on a set of 1314 individuals of 35 species, captured along a gradient of urban intensification. We found significant morphological changes associated with urban intensification by evaluating ten ecomorphological traits and body mass of the species assemblage. Beak length showed the most dramatic changes, and was significantly shorter as a function of urban intensification, mainly in individuals of insectivorous and omnivorous species. These results reinforce the notion that environmental changes caused by human activities in dense urban environments promote new selective pressures in resident bird species.KEYWORDS: Ecomorphologyurban areaurban animalsurban sprawlurban biodiversityurbanisation intensity AcknowledgmentsWe thank the Rufford Foundation for the grant support that made this study possible (Project 36888-1), the Brazilian education agency ‘Coordenação de Aperfeiçoamento de Pessoal de Nível Superior’ (CAPES) for a PhD fellowship to EGS, and CNPq for a researcher fellowship to MÂM.

Flamingos are unique and distinctive species that live exclusively in these environments and are highly impacted by any changes in their breeding or non-breeding wetlands. To address and measure the direct impact that future climatic changes could have on the distribution of the six extant species of flamingos, I used citizen science data and climatic variables to construct habitat suitability models. These models were used to predict the future gain or loss of climatic suitability areas in the short, medium, and long term, under four different Shared Socioeconomic Pathways and eight Global Circulation Models. The results predicted that five out of the six species of flamingos will experience continued loss of habitat over the next few decades in all scenarios. Dramatic changes in distribution are expected for all species. The data also indicate a higher impact of climate change on more habitat restrictive species and on wetlands along the borders of their distributions. Finally, the research highlights the importance of combined efforts from public communities, scientists, and policymakers to create mitigation and conservation plans that could avoid the intensification of climate change effects on wetlands and prevent the future reduction of flamingo populations.KEYWORDS: Climate changeconservationflamingoshabitat suitability modelsPhoenicopteriformes AcknowledgmentsI am grateful to Federal University of Rio Grande do Sul for putting the facilities of the laboratory at my disposal.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data used to support the study were collected on freely available online research databases; further details on the models are available in the Supplementary Materials.Supplementary dataSupplemental data for this article can be accessed at https://doi.org/10.1080/01584197.2023.2257757.Additional informationFundingThe author is supported by a Doctoral fellowship, from the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), Brazil.","PeriodicalId":50532,"journal":{"name":"Emu-Austral Ornithology","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136307498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Noise was recorded at each point in all areas and related to the abundance of antthrushes. Across habitat types, Rufous-capped Antthrushes were least abundant at the highway-edge, intermediate at the pasture-edge, and highest at the interior of the forest. Within habitat types, species abundance was highest in points 600 m away from the pasture but only in points 800 m away from the highway. The abundance of antthrushes was inversely correlated to noise, irrespective of habitat type (highway or pasture). These results suggest that the presence of the highway and the noise it produces are important threats to the Rufous-capped Antthrush, decreasing its abundance and possibly constraining movements across the highway. For a regionally threatened bird, these impacts could be significant for species viability.","PeriodicalId":50532,"journal":{"name":"Emu-Austral Ornithology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reported presence of this species in the fossil deposits of Naracoorte Caves suggests that it once inhabited a wooded environment. It was therefore important to assess whether the fossils are indeed conspecific with P. torquatus before inferences on the past palaeoecological preferences of the species are made. This study reassessed the identity of fossils identified as P. torquatus using both qualitative observations and morphometric analyses to test for proportional differences of fossil specimens which might indicate taxonomic distinction. Measurements were collected from fossils attributed to Pedionomus from Blanche Cave (45–15 ka) and Victoria Fossil Cave (>400–220 ka), and compared with modern skeletal specimens through univariate and principal component analyses. Fossil elements were significantly larger than the modern specimens, although marked overlap was consistently observed, precluding unambiguous differentiation on size. No qualitative traits distinguishing the two groups could be identified. The Naracoorte fossil Pedionomus are therefore considered to represent a population of P. torquatus, wherein birds were slightly larger than extant ones. The Naracoorte deposits sampled a forest and woodland-dominated environment over the last 400,000 years, one which would be deemed unsuitable for modern Plains-wanderers, indicating that P. torquatus may have formerly occupied a much broader range of habitats than its present distribution suggests. It is inferred that the Plains-wanderer underwent a marked contraction in occupied habitat during the Holocene.","PeriodicalId":50532,"journal":{"name":"Emu-Austral Ornithology","volume":"5 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88256025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endangered Yellow-eyed Penguins (Megadyptes antipodes) are declining on South Island, New Zealand, where modelling published in 2017 predicted their extirpation by 2043. Four management plans dating back to 1989 have been implemented in attempts to mitigate threats. The first three plans overlooked rehabilitation whereas the most recent, published in 2020, regarded rehabilitation as essential to save the South Island population. We assess the outcome of four decades of management of Yellow-eyed Penguins at Moeraki, southeast South Island, by Penguin Rescue, a volunteer conservation organisation. Here, nest numbers have fluctuated but overall increased at a long-term annual average of 5%. Their proportion of the southeast South Island total rose from 1% (six of about 453 nests) in 1982 to 26% (43 of about 166 nests) in 2021. Since 1986 our management has included rehabilitation of all juvenile or adult Yellow-eyed Penguins we encountered locally with life-threatening injuries, emaciation or sickness, with 590 of these marked before release from our rehabilitation facility. We accounted for the effect of rehabilitation on nest numbers by subtracting the number of rehabilitated female breeders and their female descendants from the total number of female breeders. Without rehabilitation nest numbers at Moeraki in 2021 probably would have remained similar to the initial six nests in 1982 instead of the seven-fold increase through four decades. We conclude that rehabilitation is an effective management technique for this species.","PeriodicalId":50532,"journal":{"name":"Emu-Austral Ornithology","volume":"5 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88863044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduced predators and land-use change are key drivers of population decline in this group. Where multiple threats may compound the impacts on species, the implementation of complementary approaches to threat assessment can be especially valuable. Using Norfolk Island (NI) in the south-west Pacific as an exemplar, we assessed daily nest survival rates for five endemic songbirds (NI Robin Petroica multicolor, NI Gerygone Gerygone modesta, Slender-billed White-eye Zosterops tenuirostris, NI Whistler Pachycephala pectoralis xanthoprocta and NI Fantail Rhipidura albiscapa pelzelni), monitoring 135 nests over four breeding seasons. To understand the factors associated with suitable breeding habitat, we also conducted ecological niche modelling in Maxent for all species. Depredation was the primary driver of nest failure across all species (80% of failed nests), with invasive rats (Rattus sp.) being the most common predator (61% of depredated nests) and a key predictor of nest survival. Gerygones and Fantails exhibited the highest nest survival and were also categorised as habitat generalists using ecological niche modelling. Conversely, the three species that exhibited lower nest survival (Robin, White-eye and Whistler) had specialised habitat requirements, highlighting the potential for cumulative impacts. Our data suggest that invasive rodent control within intact forested sites is a critical management action for this system, followed by strategic habitat restoration and increased connectivity. Our study provides essential ecological information for five poorly understood island songbirds and identifies key management strategies for a regional avian hotspot.","PeriodicalId":50532,"journal":{"name":"Emu-Austral Ornithology","volume":"34 1","pages":"217 - 231"},"PeriodicalIF":1.3,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85731534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since then, he has conducted ground-breaking research on some of our most challenging and endangered avian species, including Swift Parrots, Orange-bellied Parrots, Palm Cockatoos, Eclectus Parrots, Forty-spotted Pardalotes, Norfolk Island Green Parrots and Regent Honeyeaters. He has published 200 papers and two books with profound impact in academic and conservation spheres, including publications in the highest ranking academic journals (eg Science). Professor Heinsohn’s landmark research in bird behaviour includes his discovery of kidnapping in white-winged choughs, the causes of extreme sexual dichromatism in Eclectus parrots, analysis of tool use and rhythmic drumming in Palm Cockatoos, and the impacts of introduced predators on the mating system and sex allocation of Swift Parrots. His research has established Australian birds as textbook examples of behavioural and evolutionary processes (eg Davies et al. 2012 An Introduction to Behavioural Ecology, Wiley-Blackwell; Lovette & Fitzpatrick 2016 Handbook of Bird Biology, Wiley). His co-edited book Boom and Bust: Bird Stories for a Dry Country explored the adaptations of Australian birds to erratic weather and won Australia’s most prestigious award for zoological publications, the 2009 Whitley Medal (Royal Zoological Society, NSW). He served as Associate Editor for Emu Austral Ornithology for over a decade, and co-edited a special issue on parrots in 2019. Professor Heinsohn’s research has had immense impact on the conservation of Australian birds in four key ways. First, he and his team have discovered a range of previously unknown threats and devised numerous innovative solutions. Examples include his group’s development of hi-tech nest boxes to protect Swift Parrots from catastrophic predation, providing feathers treated with insecticide to Fortyspotted Pardalotes, thereby enabling them to self-fumigate their nests against parasitic flies, and teaching captive reared Regent Honeyeaters to sing the correct song upon release. Second, Professor Heinsohn has used his analytical skills for optimal conservation planning. For example, working with BirdLife and the Regent Honeyeater recovery team in 2021, he led a population viability analysis to identify the levels of nest protection and captive breeding necessary for population recovery. This analysis is an essential part of the blueprint for reviving the fortunes of Regent Honeyeaters over the next 20 years.
