Raptors provide critical ecosystem services, yet there is currently no systematic, global synthesis of their conservation status or threats. We review the International Union for Conservation Nature's Red List to examine status, distributions, threats, and recommendations all 557 raptor species. further assess significance Important Bird Biodiversity Areas (IBAs) conservation. also determine which countries contain most species listed under Memorandum Understanding on Migratory Birds Prey in...
Abstract Aim Raptors serve critical ecological functions, are particularly extinction‐prone and often used as environmental indicators flagship species. Yet, there is no global framework to prioritize research conservation actions on them. We identify for the first time factors driving extinction risk scientific attention raptors develop a novel priority index (RCPI) priorities. Location Global. Methods use random forest models based traits extrinsic data drivers of in all raptors. then map...
Abstract Understanding the distribution of biodiversity across Earth is one most challenging questions in biology. Much research has been directed at explaining species latitudinal pattern showing that communities are richer tropical areas; however, despite decades research, a general consensus not yet emerged. In addition, global patterns being rapidly altered by human activities. Here, we aim to describe large‐scale richness and diversity terrestrial vertebrate scavenger...
Abstract The prosperity and well‐being of human societies relies on healthy ecosystems the services they provide. However, biodiversity crisis is undermining functions. Vultures are among most imperiled taxonomic groups Earth, yet have a fundamental ecosystem function. These obligate scavengers rapidly consume large amounts carrion waste, service that may aid in both disease prevention control mammalian scavengers, including feral dogs, which turn threaten humans. We combined information...
Abstract Long‐distance migrations are among the most physically demanding feats animals perform. Understanding potential costs and benefits of such behaviour is a fundamental question in ecology evolution. A hypothetical cost migration should be outweighed by higher productivity and/or annual survival, but few studies on migratory species have been able to directly quantify patterns survival throughout full cycle across majority species’ range. Here, we use telemetry data from 220 Egyptian...
Human-induced direct mortality affects huge numbers of birds each year, threatening hundreds species worldwide. Tracking technologies can be an important tool to investigate temporal and spatial patterns bird as well their drivers. We compiled 1704 records from tracking studies across the African-Eurasian flyway for 45 species, including raptors, storks, cranes, covering period 2003 2021. Our results show a higher frequency human-induced causes than natural taxonomic groups, geographical...
Disentangling individual- and population-level variation in migratory movements is necessary for understanding migration at the species level. However, very few studies have analyzed these patterns across large portions of species' distributions. We compiled a telemetry dataset on globally endangered Egyptian Vulture Neophron percnopterus (94 individuals, 188 completed journeys), tracked ~70% global range, to analyze spatial temporal variability within among individuals populations. found...
Abstract Aim Animal movement is an important determinant of individual survival, population dynamics and ecosystem structure function. Nonetheless, it still unclear how local movements are related to resource availability the spatial arrangement resources. Using resident bird species migratory outside period, we examined distribution resources affects patterns both large terrestrial birds (e.g., raptors, bustards hornbills) waterbirds cranes, storks, ducks, geese flamingos). Location Global....
The organization of ecological assemblages has important implications for ecosystem functioning, but little is known about how scavenger communities organize at the global scale. Here, we test four hypotheses on factors affecting network structure terrestrial vertebrate and its functioning. We expect to be more nested (i.e. structured): 1) in species‐rich productive regions, as nestedness been linked high competition carrion resources, 2) regions with low human impact, because most efficient...
Abstract Species assemblages often have a non‐random nested organization, which in vertebrate scavenger (carrion‐consuming) is thought to be driven by facilitation competitive environments. However, not all species play the same role maintaining assemblage structure, as some are obligate scavengers (i.e., vultures) and others facultative, scavenging opportunistically. We used database with 177 from 53 22 countries across five continents identify functional traits of key network structure....
Proactive approaches are typically more cost-effective than reactive ones, and this is clearly the case for biodiversity conservation. Research conservation actions Old World vultures followed large population declines, particularly in Asia Africa. These clear examples of intensive management. We here contend that there signs a potential upcoming continental vulture crisis New World. Word share many threats have decimated their counterparts, such as toxicosis from poisoning lead. At same...
Migrant birds face a number of threats throughout their annual cycle, including persecution, collision with energy infrastructure, and habitat climate change. A key challenge for the conservation migrants is identification important habitat, migratory concentration areas, because species survival rates may be determined by events in geographically very limited areas. Remote‐tracking technology facilitating such critical although strategic sites incorporation knowledge planning remains...
Most raptor populations are declining and nearly a fifth threatened with extinction; thus there is need to increase collaboration ensure efficient effective research, management, conservation. Here, we introduce the Global Raptor Impact Network (GRIN; www.globalraptors.org), tool enhance conservation impact of research community. We provide an overview history current state GRIN, including plans for expansion. Predecessors GRIN include The African DataBank, which was launched in 2012...
In the midst of sixth mass extinction, limited resources are forcing conservationists to prioritize which species and places will receive conservation action. Evolutionary distinctiveness measures isolation a on its phylogenetic tree. Combining species' evolutionary with globally endangered status creates an EDGE score. We use scores that should be managed conserve bird history. analyzed all birds in countries important areas. examined parrots, raptors, seabirds depth because these groups...
Wetland-dependent migratory songbirds represent one of the most vulnerable groups birds on planet, with >67% wetland-obligate species threatened extinction. One major hurdles for conservation efforts is determining migration routes, stopover sites, and wintering sites these species. We describe an annual cycle revealed by geolocator tracking Great Reed-Warblers (Acrocephalus arundinaceus) breeding in Aras River wetlands eastern Turkey. Because its relatively large size ground fidelity,...
Summary Vulture populations are in severe decline across Africa and prioritization of geographic areas for their conservation is urgently needed. To do so, we compiled three independent datasets on vulture occurrence from road-surveys, GPS-tracking, citizen science (eBird), used maximum entropy to build ensemble species distribution models (SDMs). We then identified spatial priorities Ethiopia, a stronghold vultures Africa, while accounting uncertainty our predictions. were able robust five...
The Global South harbors a large share of imperiled biodiversity. Effective research and conservation in the are negatively affected by weak or turbulent socio-political contexts, such as poor governance and/or high violence levels. There is need to understand how priorities for relate different levels governance, order highlight opportunities challenges biodiversity conservation. We explore spatial overlap between density raptor priorities, unveil effect considering when prioritizing areas...
Tracking studies are often used to inform conservation plans and actions. However, species have frequently only been tracked in one or a few localities, whereas space use can be remarkably flexible, especially long‐lived with advanced learning abilities. We assessed variability the Critically Endangered Hooded Vulture Necrosyrtes monachus by pooling movement data from three populations across species’ sub‐Saharan range (in South Africa, Botswana, Ethiopia, Kenya, The Gambia Mozambique)....
