Preliminary effects of UAS angle of approach on escape responses of a large-bodied raptor

Drone Systems and Applications
Animal responses to unoccupied aircraft systems (UAS) can be exploited to reduce human-wildlife conflicts. We investigated how same-level UAS approaches (0°) would be perceived by Turkey Vultures (Cathartes aura; “vultures”) compared to stoop approaches (

Global patterns and gaps in the study of terrestrial birds and mammals' use of freshwater sources: a mapping review

Wildlife Biology, Volume 2025, Issue 5, September 2025.
Water availability strongly influences the ecology of terrestrial birds and mammals. It will likely play an increasing role as a limiting factor as climate change and human demand make water availability scarcer. However, we lack a knowledge synthesis describing our current understanding of the use of water sources, particularly for wildlife hydration.

Using multiple data sources to investigate foraging niche partitioning in sympatric obligate avian scavengers

Ecosphere, 2019
As carrion feeders competing for a limited and ephemeral resource, avian scavengers are ideal model organisms to study mechanisms of niche partitioning.

Nestling carcasses from colonially breeding wading birds: patterns of access and energetic relevance for a vertebrate scavenger community

Scientific Reports, 2019
Energy transfer is fundamental to ecosystem processes, affecting productivity and community structure. Large aggregations of colonially breeding birds are known as nutrient sources through deposition of feces, but also may deposit large quantities of ...

Effects of wind farms on raptors: A systematic review of the current knowledge and the potential solutions to mitigate negative impacts

Animal Conservation, Volume 28, Issue 3, Page 334-352, June 2025.
Our review of 195 studies highlights the consensus on raptors’ avoidance behavior and population decline post‐wind farm installation, emphasizing the significant risks posed by mountaintop wind farms to soaring raptors. Adult raptor mortality, particularly among endangered species, and the elevated collision risks faced by young individuals underscore ...

Maintenance of syntenic groups between Cathartidae and Gallus gallus indicates symplesiomorphic karyotypes in new world vultures

Genetics and Molecular Biology, 2011
Similarities between New World and Old World vultures have been interpreted to reflect a close relationship and to suggest the inclusion of both in Accipitridae (Falconiformes).

Evidence of niche differentiation for two sympatric vulture species in the Southeastern United States

Movement Ecology, 2019
Background As obligate scavengers utilizing similar habitats, interspecific competition undoubtedly occurs between resident black (Coragyps atratus) and turkey (Cathartes aura) vultures.

Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance

Ecology and Evolution, Volume 15, Issue 5, May 2025.
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

Diversidad de aves rapaces diurnas en la Reserva de la Biosfera Selva El Ocote, Chiapas, México Diversity of diurnal raptors in the Biosphere Reserve Selva El Ocote, Chiapas, Mexico

Revista Mexicana de Biodiversidad, 2009
La pérdida y degradación de ambientes naturales está afectando a grupos funcionales de gran relevancia, como las aves rapaces diurnas. En este estudio evaluamos la variación espacial de la diversidad de este grupo en la zona núcleo y de amortiguamiento ...

FOGS: A SNPSTR Marker Database to Combat Wildlife Trafficking and a Cell Culture Bank for Ex‐Situ Conservation

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.
