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 (

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.

Monitoring faunal responses to biodegradable oyster reef restoration materials with camera traps in a subtropical estuary

Restoration Ecology, Volume 33, Issue 8, November 2025.
Oyster reef restoration has become increasingly crucial due to global population declines. Intertidal oyster reefs provide essential foraging and loafing (resting) grounds to estuarine fauna. To reduce plastic pollution from traditional materials, biodegradable restoration materials have been introduced and are shown to support oyster recruitment ...

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 ...

Inclement weather forces stopovers and prevents migratory progress for obligate soaring migrants

Movement Ecology, 2021
Background Migrating birds experience weather conditions that change with time, which affect their decision to stop or resume migration. Soaring migrants are especially sensitive to changing weather conditions because they rely on the availability of ...

Functional and phylogenetic convergence of winter and breeding bird communities in the northeastern US

Ecography, Volume 2025, Issue 10, October 2025.
Around the world, ecological communities are becoming more similar to one another in a process known as biotic homogenization – an increase in similarity among communities over time. While biotic homogenization has been widely studied among spatial communities, very little attention has been paid to beta diversity between seasonal communities ...

Community‐informed and codesigned research to understand the impacts of railways on wildlife

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Past research and future directions in understanding how birds use their sense of smell

Ibis, Volume 167, Issue 4, Page 853-881, October 2025.
Our understanding of the functional importance of olfaction to birds has improved over the past 60 years, largely as the result of experimental studies testing how birds use their sense of smell in different contexts. As it is impossible to measure directly which odours birds can detect, we rely on measuring behavioural responses to scent cues or ...

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 ...

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.
