In a viral video on social media on the weekends, bear cubs walk through snowy steep slopes toward their mother. The bear climbs a few steps and slides down and tries again until it is finally over. It's a video that inspires thousands of people who share it. To wildlife experts, it is irresponsible acrobatics that put bears at risk.
This post was patrolling on Facebook when Ziya Tong, a science communicator, first posted on Twitter on Saturday on Twitter.
Since then Tong's post has been retweeted over 165,000 times through criticism of Twitter by wildlife biologists and other experts .
Can you solve the problem of wildlife welfare due to drones and harassment here? I'm glad to see wildlife tweets, but it seems important to deliver the right message. Clayton T. Lamb (@ClaytonTLamb) November 5, 2018
In a trained eye the video shows a terrified mother bear It shows. She may be panicked by a steep trek along the ridge. Mark Ditmer, a postdoctoral fellow at Boise State University, says, "The bears, apparent to me according to the way they are moving, are significantly hindered by unmanned aerial vehicles that capture video.
Backlash uses unmanned aircraft around wildlife Tong has posted a best practice for shooting wildlife unmanned aerial photography, but decided not to delete her tweets: "Without video, viral people will not talk about the topic at all, Tong says in his direct message on Twitter
We do not know that the video was taken by an unmanned airplane. Tong tracked the video to the YouTube account ViralHog. The representative stated in the email, "It is an unmanned aircraft video "The clip emphasizes the continuing tension between the landscape of unprecedented wildlife provided by unmanned aircraft and the fact that the unmanned aerial vehicle may be at risk. These are the animals that they shoot." This is how the unmanned aircraft "
A few years ago, Ditmer saw how a bear responded to an unmanned aircraft The bears were equipped with a heart-rate monitor so that they could monitor their heart rate as they traversed the road, or the quad-cop ran overhead, as the unmanned aircraft flew. A couple of masked bears ran out.
Why a large and powerful bear is scared of drone aircraft.
The big bear is intimidated by the unmanned airplane. Do you eat? Ditmer suspects that a loud drone, which is nowhere to be seen, has lured the bear underneath. Fear can explain the dangerous pathways that a mother and cub have taken a viral video. "I think I must have chosen this way, or if it is not too close to the foreign thing to buzz, I will take that route much more carefully and slowly," he says.
But Drones is inherently a problem, he says. "In all these cases, it's about responsible use rather than being wrong," he says. To this end, the ecologists at the University of Adelaide, Jarrod Hodgson and Lian Pin Koh, have set out best practices for scientists who fly drones near wildlife. These are published in the journal Current Biology in 2016 . However, relevant unmanned aircraft operators, especially those who use unmanned aircraft in scientific research, provide summary information such as:
- Unmanned aircraft Near an animal if you do not know how the animal responds. These reactions are unique to each species. They are complicated. It may change over time.
- Follow the agency's ethical guidelines and civil aviation rules.
- Please use the best possible equipment. That is, choosing quiet, unobtrusive, unmanned aircraft. You can also fly high above the animal using the most sensitive sensor.
- Start and recover a drone away from an animal. Steer unmanned aircraft and stay away from animals.
- If you are harassing animals, stop flying unmanned aircraft.
- Please report exactly what you did in the publication.
"There is always a conflict between how useful you are to collect useful data and how far away you are," Ditmer says. Calculation is simpler for recreational drone users. Follow the rules and do not harass wildlife. So for obvious scientific purposes, there is a clear choice between getting a good video of two bears or putting the bears alone. Do not bother the bear.
