Under an around-the-clock summer sun, a young Arctic fox set out in July 2019 from Bylot Island in Nunavut, Canada.He wandered over the tundra for 299 days, probably alone, trotting an astonishing 6,400 kilometers before reaching a new home.A tracking collar confirmed the record-breaking journey.We knew Arctic foxes could go far, says University of Quebec ecologist Dominique Berteaux, who has led an Arctic foxtracking project for 20 years.
