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

Wildlife 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

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

Wildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Benefit or ecological trap? Monitoring the effects of small clear‐cuts on capercaillie Tetrao urogallus and its mammalian predators

Wildlife Biology, EarlyView.
The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

Wildlife Biology, EarlyView.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.
