Covering over 3,500 kilometers (2,200 miles) on polar ice sheets in only 76 days, an arctic fox has reached Canada after setting off from Norway in an unprecedented feat of endurance.
The journey is not only a testament to the fox’s stamina but also highlights the important role ice sheets serve for the migration of Arctic wildlife and the threat global warming poses to the ecological balance.
Arnaud Tarroux, one of the researchers behind the study recording the fox’s trek published by the Norwegian Polar Institute, warned that “less ice will mean fewer opportunities for this type of migration.”
The arctic fox was equipped with a satellite tracker in July 2017 and set off from the island of Spitsbergen in the Norwegian Svalbard archipelago, about 1,000 kilometers from the North Pole, on March 26, 2018.
On June 10, 76 days after leaving Norway, the fox reached Ellesmere Island, one of Canada’s northernmost communities, completing a journey of 3,506 kilometers.
“This species is more enduring and faster than what has been observed in the past,” Arnaud Tarroux told AFP on Wednesday, July 3. “It is a young female, less than a year old, therefore relatively inexperienced, literally going out to discover the world and surviving the Arctic crossing on her first attempt.”
Adding to the impressive feat is that the young vixen covered the first 1,512 kilometers to reach Greenland in just 21 days.
“This is the first observation that shows in detail that an arctic fox has migrated between different continents and ecosystems in the Arctic, and one of the longest migrations ever recorded for an arctic fox in such a short period of time,” the Norwegian Polar Institute noted in a statement.
The fox withstood the arid polar environments and moved at an average daily rate of 46.3 kilometers, with a daily record of 155 recorded while crossing Greenland.
Why the fox opted to leave for Canada is unclear.
“It is quite possible that it is simply a series of coincidences that led her to find herself in an area of the Canadian Arctic at the right time to find enough resources to be able to settle there,” Tarroux said.
The fox’s current whereabouts are unknown since the tracking system stopped working in February 2019. HM/JB
