Australia recently committed through the Kunming-Montreal Global Biodiversity Framework (GBF) to halt human-induced extinction of known threatened species and reduce risk significantly by 2030. We review recent trends in Australian birds provide context for current future conservation efforts. calculate Red List Index (RLI) all as well subsets based on geography, habitat taxonomy. Over period 2010 2020, number taxa reassigned lower categories (n = 20; 1.5% included) was greatly outweighed...
Abstract Comparative extinction risk analysis—which predicts species from correlation with traits or geographical characteristics—has gained research attention as a promising tool to support assessment in the IUCN Red List of Threatened Species. However, its uptake has been very limited so far, possibly because existing models only predict species' category, without indicating which criteria may be triggered. This prevents such approaches integrated into assessments. We overcome this...
Over 750 native bird species reside in or regularly migrate to Australia, many of which have experienced rapid changes habitat extent over the past two centuries. By 2020, eight taxa were considered Extinct and 10% threatened with extinction. Understanding underlying extrinsic intrinsic factors that increase extinction risk can allow prioritisation conservation management research. Here, we use state-of-the-art phylogenetic comparative models reveal most important biological traits...
Banda Myzomela boiei (S. Müller 1843) is a small honeyeater distributed in two subspecies across three island groups Maluku Province, Indonesia: M. b. on the Islands, and c.350 km to south, annabellae Tanimbar Islands Babar. We compare data from 28 museum specimens 21 sound recordings, report results of 152 playback experiments, investigate taxonomy these populations. Compared annabellae, has c.10% longer wing, bill tarsus, more extensive black breast-band, duskier posterior underparts,...
The genus Syma Lesson, 1827 is unanimously considered to comprise two very similar, altitudinally-segregated species in the New Guinea bioregion: Yellow-billed Kingfisher S. torotoro and Mountain megarhyncha. One taxon, t. ochracea of D’Entrecasteaux Archipelago off eastern Guinea, has recently been suggested as an independent species, but evidence so far remained unassembled. Here, I combine morphometric plumage data 127 museum specimens (including 34 ochracea), bioacoustic from 52 sound...
Most biodiversity monitoring globally tends to concentrate on trends in species' populations and ranges rather than threats their management. Here we review the estimated impact of extent which management is understood implemented for all Australian threatened bird taxa. The assessment reports situation 2020 how this differs from 2010. most marked finding was that climate change has increased greatly over last decade, now surpasses invasive species as threat imposing heaviest load. Climate...
Reducing extinction risk is a common aim of threatened species management. However, over the period 1990 to 2020, was recently assessed as having declined in only 25 out 199 Australian bird taxa eligible for assessment. Here we analyse patterns that emerge from these taxa. Some improvements may be temporary; three increased after it had initially declined. Invasive predator control on islands conservation intervention with greatest impact, benefitting 13 (with nine Macquarie Island). For...
We used photo-documented citizen science data held in publicly accessible databases to better elucidate the diet of one smallest Neotropical Accipitridae, Tiny Hawk (Accipiter superciliosus). Previous are exclusively anecdotal, but a suggestion that this species is some extent specialized predator on hummingbirds (Trochilidae) widely reported literature, despite being based few observations. Using total more than 680 photographs Hawks, we identified 33 items avian prey from 15 families and...
The Kangean islands are a biologically poorly known archipelago situated in the Java Sea, Indonesia, approximately 120 km directly north of Bali. These host an avifauna comprising at least 13 endemic subspecies, two which have by some sources recently been considered species. We combine historical published literature with our own surveys 2007–2008, 2010 and 2023 to produce complete list islands’ birds (n=140 species) their distribution across islands. evaluate more detail conservation...
The subspecies of Barbary Partridge Alectoris barbara confined to northeast Libya and adjacent Egypt, A. b. barbata, has recently been posited merit species rank, with the additional suggestion that it might be among Western Palearctic's most threatened avian taxa. As a first step assessing its conservation status, we review distribution habitat barbata by collating all records information available us, including published literature, unpublished observations museum holdings, adding evidence...
Abstract Wild birds have experienced unprecedented, near‐global mass mortalities since 2021, driven by outbreaks of high‐pathogenicity avian influenza virus (HPAIV) H5N1 lineage 2.3.4.4b. Managing this panzootic requires identification transmission pathways. We investigated potential HPAIV via kleptoparasitism (food theft) examining the distribution, behaviors, and movements two globally widespread commonly kleptoparasitic seabird families: Fregatidae (frigatebirds) Stercorariidae (skuas)....
In the current biodiversity crisis, conservation efforts are often focused on extinction prevention. However, it can be difficult to determine if a species is extinct, especially has an extensive range, including being transcontinental migrant, or poorly known. The breeding range of migratory Critically Endangered Slender‐billed Curlew Numenius tenuirostris uncertain, and non‐breeding that spans central Asia, eastern Europe, Middle East, Mediterranean basin northwest African coast. There...
Abstract Compilation and scrutiny of all accessible specimen observer records the long-tailed woodnymph Thalurania watertonii , a hummingbird currently listed as ‘Endangered’ on IUCN Red List, eliminates Guyana, Pará, Maranhão, Ceará, Rio Grande do Norte Paraíba from its range sets aside both Sergipe Bahia unproven, leaving 29 certain localities, 15 in Pernambuco 14 Alagoas, north-east Brazil, them Atlantic Forest not Cerrado or Caatinga. Among are ten category I‒IV protected areas (seven...
Ruby-throated Bulbul Rubigula dispar, currently Vulnerable on the IUCN Red List owing to trade pressure, is considered monotypic across its range three Sundaic islands in Indonesia: Sumatra, Java and Bali. However, examination of photographs museum specimen labels measurement 37 Sumatran 50 Javan specimens indicate that birds from Sumatra differ those (type locality) Bali exhibiting a variably red (not pale yellow) iris slightly longer bill wing. Consequently, we propose subspecies rank for...
Rusty-cheeked Scimitar Babbler Erythrogenys erythrogenys (Vigors, 1832) comprises two subspecies in the Himalaya (nominate and ferrugilata) more, disjunctly (with Spot-breasted E. mcclellandi interposing), Myanmar Thailand (imberbis celata). Prompted by observation that these populations appear to exhibit differences eye colour, we use citizen science data (343 online photographs >100 sound-recordings) 66 museum specimens evaluate potential bare-part plumage morphometrics vocalisations. We...

Abstract Chotoy spinetail Schoeniophylax phryganophilus is widely distributed in southern and eastern South America. What was believed to be a geographically disjunct population described, as S. p. petersi , from Brazil, the valley of Rio São Francisco, northern Minas Gerais western Bahia, based on comparatively minor plumage characters (chiefly colour strength streaking). Its range subsequently extend northeast Brazilian state Piauí. We analysed total 91 specimens (74 17 ) for external...
White-eyed River Martin Pseudochelidon sirintarae was described in 1968 and there have been no confirmed sightings since the 1970s. It is known only from Bueng Boraphet central Thailand. Here, we compile most comprehensive summary of museum specimens, photographic records (including two previously unpublished images) for this poorly species. Specimens are held mainly Thailand Natural History Museum near Bangkok, with others at (Tring), American (New York) National History, Smithsonian...
