Arctic Fox walks from Norway to Canada

[Catherine]

This is an incredible journey. A young female Arctic Fox left Norway on March 26, 2018 and walked across the ice and arrived in Northern Canada on July 1, 2018.
She was fitted with a tracking collar so they were able to track her journey.  Being a fox she did not walk in a straight line and in all her journey was over 3,500 km.

First let me say welcome to Canada, little fox. I hope life is good to you here.
I did not know that foxes migrated in any way. This is a major migration.
I am wondering what she ate and where she sheltered. How did she know where to go.
If they hadn't been tracking the fox we would have had no idea of her journey. She would have looked like one more local fox. I hope they study this more. I wonder if other foxes make similar journeys.
