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 ...

Diversity in olfactory bulb size in birds reflects allometry, ecology, and phylogeny [PDF]

, 2015
The relative size of olfactory bulbs (OBs) is correlated with olfactory capabilities across vertebrates and is widely used to assess the relative importance of olfaction to a species’ ecology.

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 ...

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 (

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 ...

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.

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.
