Messy eaters: Swabbing prey DNA from the exterior of inconspicuous predators when foraging cannot be observed

open access: yesEcology and Evolution, 2019
Complex coevolutionary relationships among competitors, predators, and prey have shaped taxa diversity, life history strategies, and even the avian migratory patterns we see today.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Activity patterns of Eleonora’s Falcons during the pre-breeding period: the role of habitat composition on the island of Antikythira

open access: yesAvocetta, 2019
Eleonora’s Falcon is well known for its delayed breeding season among European breeding raptors, however, its relatively prolonged pre-breeding period remains to date largely understudied. In this study, we compiled information on the species’ behaviour

Monitoring active osprey nests with drones is more time efficient and less disturbing than conventional methods

open access: yesWildlife Biology, EarlyView.
Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the

From dusk till dawn: ecoacoustic monitoring reveals wind energy impacts on roding Eurasian woodcock Scolopax rusticola

open access: yesWildlife Biology, EarlyView.
Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Staying sheltered: geographical variation in nestbox use by a nocturnal raptor outside the breeding season

open access: yesWildlife Biology, EarlyView.
Tree cavities and nestboxes are crucial resources for cavity‐nesting birds. While cavities are essential for reproduction, their importance outside the breeding season remains poorly understood, with most existing evidence focusing on nestbox use by small birds to reduce heat loss during winter.

Exposure to rodenticides in Northern Spotted and Barred Owls on remote forest lands in northwestern California: evidence of food web contamination

open access: yesAvian Conservation and Ecology, 2018
The documentation of anticoagulant rodenticides (AR) in nontarget species has centered around wildlife that inhabit urban or agricultural settings. However, recent studies in California have shown that AR use in remote forest settings has escalated and ...

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

open access: yesWildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Updates on Breeding Success and Conservation Challenges for White‐Rumped Vulture (Gyps bengalensis) in Rampur Valley, Nepal 尼泊尔兰普尔山谷白腰兀鹫繁殖成功研究进展及其保护挑战

open access: yesWildlife Letters, EarlyView.
This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

From Nest to Nest: High-Precision GPS-GSM Tracking Reveals Full Natal Dispersal Process in a First-Year Female Montagu’s Harrier Circus pygargus

open access: yesBirds
This report presents the first complete natal dispersal trajectory of a female Montagu’s Harrier Circus pygargus, tracked in real time from fledging to first breeding using high-resolution continuous Global Positioning System (GPS) telemetry.
