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

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.
