I was just wondering; catching, anaesthetizing and implanting the heart monitors in the bears must have been extremely stressful experiences for them.
Is it possible those experiences were preceded by the noise of a helicopter carrying the research team? And so what's causing the bears' heart rate to spike is the reminder of that, when they hear a drone?We 'embraced' the missing Bob Harrod case as requested but 6 years on, are still waiting for further guidance
