Jonny also worked on filming millions of snow geese that fly from the southern United States to the high Arctic. When the geese arrive there, Artic foxes are waiting to prey upon them.

After spending time filming in the area, the foxes began to trust the crew. "What's fantastic is to begin with, they run away from you—the foxes—and then over a few weeks, they get really used to you, and they eventually sit at your feet and sleep, and you know then that they really trust you," Jonny says.
