Large nocturnal roosting aggregations and mass movements of Whiskered Terns in Liuwa Plain National Park, Zambia Open
The Whiskered Tern (Chlidonias hybrida) is little studied in southern Africa. In Zambia, it is primarily found in the south and west of the country, where the Barotse Floodplain and Kafue Flats are known to contain substantial numbers of t…
Ecosystem services and disservices associated with vultures: A systematic review and evidence assessment Open
Nature's contribution to people (i.e. ecosystem services) is becoming integral to conservation science and policy, yet our knowledge is restricted to only a few services and taxa. Vultures (family: Accipitridae and Cathartidae), most of wh…

Flight Altitudes of Raptors in Southern Africa Highlight Vulnerability of Threatened Species to Wind Turbines Open
Energy infrastructure, particularly for wind power, is rapidly expanding in Africa, creating the potential for conflict with at-risk wildlife populations. Raptor populations are especially susceptible to negative impacts of fatalities from…

Commentary: the Past, Present, and Future of the Global Raptor Impact Network Open
Most raptor populations are declining and nearly a fifth are threatened with extinction; thus there is a need to increase collaboration to ensure efficient and effective research, management, and conservation. Here, we introduce the Global…
A conservation criminology-based desk assessment of vulture poisoning in the Great Limpopo Transfrontier Conservation Area Open
Vulture declines are uniquely problematic for socio-ecological systems because they are nature’s most important scavengers. Intentional and unintentional poisoning, human-wildlife conflict, energy infrastructure, belief-based use, and ille…
Presumed killers? Vultures, stakeholders, misperceptions, and fake news Open
Vultures and condors are among the most threatened avian species in the world due to the impacts of human activities. Negative perceptions can contribute to these threats as some vulture species have been historically blamed for killing li…

Habitat preferences of Southern Ground-hornbills in the Kruger National Park: implications for future conservation measures Open
Understanding how a species utilises its habitat, and the processes that give rise to its movements and patterns of space use, is critical for its conservation. Southern Ground-hornbills Bucorvus leadbeateri are listed as Endangered in Sou…
A practical guide to methods for attaching research devices to vultures and condors Open
Most species of Old and New World Vultures are globally threatened and accurate scientific studies related to their conservation are therefore essential. The range of available tracking and telemetry devices is becoming wider and they are …
Movement patterns of lesser flamingos <i>Phoeniconaias minor</i> : nomadism or partial migration? Open
Waterbirds in stochastic environments exhibit nomadism in order to cater for the unpredictable availability of water resources. Lesser flamingos Phoeniconaias minor have long been thought to be nomadic waterbirds. In southern Africa, conse…
Importance of complementary approaches for efficient vulture conservation: reply to Efrat et al. Open
Efrat et al. (2020) comment on our paper, Santangeli et al. (2019), in which we identified priority areas for Old World vulture conservation. We performed spatial conservation prioritization analyses based on modeled distributions of 15 vu…
