Wolves are scary predators, kills mammals, geese and deer, but the footage captured by the Voyageurs National Park in Minnesota shows something unusual (and eating): hunting freshwater fish.
With Voyageurs Wolf Project, Voyageurs National Park and the University of Minnesota, for the first time, wolves have been documented as a source of seasonal food that hunted freshwater fishes. The finding has recently been published in the journal Mammalian Biology.
The research team uses GPS necklaces to collect wolves data in more than seven packages, every 20 minutes, the territory of the package and prey, especially beaver but deer meadows and moose wands.
The researchers have determined that wolves spend more than 20 minutes in all sites, probably eating something. And that was how a member of a wolves suspected of eating fish in 2017.
Tom Gable, a PhD student working on the project, GPS data has noticed that wolves from Bowman Bay have spent a lot of time on a stream. Gable explored a field to look for a dying test, and saw a wolf blow.
"He was really mad," said Gablek Minnesota Public Radio. "I reached about 8 and 10 meters and I had no idea. I was hiding shrubs on the banks of this stream."
Gables watched the wolf eat fish fragments and then discovered wolves in the creek on the banks of the creek. "Seeing the wolves could be forced to spend a lot of time … and wolves also had fish scales and fish traces."
The group quickly realized that this was not a sudden occurrence and configure remote cameras in that section of the dock. Two months after Discovery, Bowman Bay's GPS-wounded wolves wound up 43-63 percent while sucking across the creek.
This year, Gable and his colleagues created cameras and wolves caught at night.
Researchers have collected GPS data around seven packages, but Bowman Bay is the only fish that appears.
Scientists will know that coastal wilderness habits eat salmon eating wolves – observing the wolves originally eating salmon along the British Columbia and Alaska coasts. But this is, for the first time, hunting freshwater fish has documented a similar behavior.
It's a special diet, but experts say it's not surprising, because of the spectacular adaptability of wolves nutrition discovery, you must be in the right place at the right time to witness it.
"Especially in the high density areas of northern Minnesota, you should be at the right time at the right time or for GPS-collar data," said Joseph Bump, associate professor of research at the University of Minnesota. project advisor
One thing is certain, the gem of the footage has opened the interests of the Park and the Voyageurs Wolf project. On Facebook, the video has been more than 340,000 times, and other mailing lists in wolf packs have received over 4,000 comments and shares.
Gable said the MPR: "As far as we are doing, it's really about sharing what we meet with people and how we're excited about how people are doing it."
