Using programmable infusion pump in avian species – a validation methodology in geese
Wildlife Biology, EarlyView.Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Assessing sustainable lethal take for great blue heron in the northeastern United States
Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.We used Prescribed Take Level (PTL) models to estimate sustainable take limits for great blue heron and aid depredation permitting decisions by the USFWS in the northeastern United States. The PTL models suggested that current lethal take levels are sustainable and that cumulative authorized regional take should not exceed 2,650 individuals per year ...

A theoretical model of flock formation to understand trade‐offs between cooperation and competition
Ecosphere, Volume 17, Issue 2, February 2026.Abstract Migratory birds often form flocks during spring migration and compete for territories once they arrive at breeding sites. Understanding the emergence and structure of these flocks has important implications for avian ecology and conservation, as flocking can influence migration success, resource distribution, and population resilience. In this

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.Uncrewed aerial systems (UAS) equipped with thermal cameras are increasingly being used in wildlife research. Here, we explore the use of UAS paired with distance sampling to detect and estimate densities of waterfowl pairs and broods in Wisconsin.

BirT: A Novel Primer Pair for Avian Environmental DNA Metabarcoding
Environmental DNA, Volume 8, Issue 1, January–February 2026.The BirT primers target the mitochondrial 12S rRNA gene and are designed for avian eDNA metabarcoding. They safeguard against the amplification of mammal, fish and amphibian DNA and were successfully used to detect bird species from eDNA samples obtained in Southern Ontario. Detections were cross‐checked with eBird observations.

People and Nature, Volume 8, Issue 1, Page 4-20, January 2026.Abstract The hyperabundance of herbivores—a result of altered human relationality with the land and the extirpation of predators—is leading to large‐scale degradation of keystone ecosystems across the globe. Designing and implementing socially acceptable and cost‐effective strategies that meaningfully reduce herbivore populations while allowing for the

Journal of Anatomy, Volume 248, Issue 1, Page 82-93, January 2026.The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Falcons reduce pre‐harvest food safety risks and crop damage from wild birds
Journal of Applied Ecology, Volume 62, Issue 12, Page 3327-3340, December 2025.In the absence of American kestrels, there are more birds in orchards. This leads to increased crop damage and more bird faecal contamination. Abstract Foodborne illness outbreaks have heightened pressures on growers to improve food safety, including mitigating possible threats from wildlife. Among wildlife, birds are particularly challenging to deter,

Environmental DNA, Volume 7, Issue 6, November–December 2025.In this study, we provide the first comparison of airborne eDNA with observer‐based surveys and passive acoustic monitoring, alongside camera traps, to monitor birds and mammals in a Dutch agroforestry system. Airborne eDNA showed the highest potential species diversity, detected many unique species–including invasive mammals–and complemented ...

The Journal of Wildlife Management, Volume 89, Issue 8, November 2025.We incorporated landscape suitability into a trumpeter swan range expansion model. We estimated a 4.4% (95% CI: 2.0–6.9%) annual range expansion rate from 2023 to 2033, with expansion occurring in the Prairie Pothole Region of the Dakotas and the Boreal Shield and James Bay Lowlands of Canada. Abstract The Interior Population of trumpeter swans (Cygnus
