I heard a story on NPR recently about how observation drones employed to observe wildlife raise the heart rates of the animals they are observing.
In the case of the story, black bears in the wild. The take-home message was that the drones interfere with the health and well-being of the critters.
The bears that the drones were being tested on had previously been caught, anesthetized, radio-tagged, and had heart rate monitors surgically implanted.
I wonder how those interventions affected their heart rate. Hmmm?
Anyway, this is what an eagle thinks of the drones.
