Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

open access: yesWildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Population trends of dabbling ducks wintering in the alluvial valleys of Arkansas and Mississippi

open access: yesWildlife Biology, EarlyView.
Population abundances, distributions, and compositions across a diversity of taxa are changing, partly as a consequence of human‐induced global modifications. Although linking population fluctuations to anthropogenic‐induced alterations can be challenging, it is increasingly clear that long‐term monitoring is critical to understanding changing ...

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

open access: yesWildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.
