Behavioural response of moose Alces alces and brown bears Ursus arctos to direct helicopter approach by researchers
Abstract Helicopters are used for numerous wildlife management and research purposes, but can alter wildlife behaviour and influence baseline data collection. We investigated reactions of GPS‐collared moose Alces alces and brown bears Ursus arctos to short‐term helicopter approaches by researchers....

Abstract Helicopters are used for numerous wildlife management and research purposes, but can alter wildlife behaviour and influence baseline data collection.

Brown bears decreased their speed and remained within similar habitat types and terrain. The movements were influenced only about two hours and did not influence the size of the activity areas.
