It’s even more impressive when you consider she was rubbing her shoulder on the ground the entire 2,700 miles trying to get the transponder to come off.

Surely you mean that she checked several social media feeds on the smartphone she was outfitted with every half mile. And that at least five ad companies and twenty trackers followed her journey, none of which correctly deduced that she was a fox.

Wow, I assumed that there was so much water surrounding Greenland that it would be impossible for a fox to swim or get there by themselves. Any idea how much of the path to Greenland from the poles and Canada is covered by ice and how far is pure water?

I don't understand why articles like this cant have a map? id argue almost every news article should have a map, giving it context locally, regionally and globally. But especially when you're talking about a crazy trek, even if it was just two points on a map - context is king.

ah, my apologies, maybe I missed that the first time. Thanks for sharing!

Here's the sea ice extent this year: http://nsidc.org/arcticseaicenews/files/2019/04/Figure1.png

Compare the fox's journey of 2,176 miles in 76 days to the average Pacific Crest Trail through hiker's 2,660 miles in 152 days. That's 29 vs 18 miles per day. The PCT record is about 50 miles per day. So an athletic human could have kept up with this canine. Of course the humans don't have to scavenge their meals along the way and the fox doesn't have to carry supplies. Typically dog companions don't do well on such…

Walking a trail isn’t the same as walking cross country. Humans aren’t very good at off trail navigation.

Most aren't. Some are.

How much sleep does the fox need vs. a human?

Earlier quoted context omitted.

Which a primate can fashion out of multiple foxes.

Have to catch them first...

Well but that's the thing - we can out walk a vast majority of animals on this planet. Early human hunters were successful partially because they could chase their prey for days if needed until it collapsed from exhaustion. We might have not have the same speed as some of the animals, but human endurance is unparalleled in the animal world.
