‘You’re Invisible, But I’ll Eat You Anyway.’ Secrets Of Snow-Diving Foxes

Here’s a link to Ed Yong’s piece this is based on.

It’s hard to really critique analysis based on a popular summary of research, but to me the explanation of using the earth’s magnetic field as a “rangefinder” seems lacking, since the foxes aren’t jumping a fixed distance to nab their prey. Still, however they are doing this it’s neat.

There’s an additional bit on kottke, showing acoustic location instruments (“war tubas”) which were used until radar took over. Cool.
