Drones Stress Out Bears

If humans can be annoyed by unwanted drones flying overhead, so do bears, according to a recent study made by researchers from the University of Minnesota who found that drones can stress out bears.

In its report, the Los Angeles Times said:

Drones flying near American black bears in Minnesota caused the animals’ heart rates to soar, even though few bears showed any outward symptoms of stress, according to a new study led by University of Minnesota researchers.

The findings, published in the journal Current Biology, could help researchers learn to better deploy drones to study animals without adversely affecting them, and help provide insight into how drones’ rising presence could affect sensitive or endangered populations.

The discovery suggests that drones will need to be much quieter, and less intrusive overall, if they’re going to monitor animal populations. Even the latest drones typically emit a loud buzz, which is only helpful if you’re trying to scare critters out of a given area. – Read more at:

Mark Ditmer, of the University of Minnesota, St Paul, said: “Some of the spikes in the heart rate of the bears were far beyond what we expected. We had one bear increase her heart rate by approximately 400% – from 41 beats per minute to 162 beats per minute. Keep in mind this was the strongest response we saw, but it was shocking nonetheless.” – Read more:
