   Despite weighing less than a paperclip, monarchs migrate up to 4,800 km from Canada to mountain forests in central Mexico.

   House sparrows have followed humans to every continent except Antarctica — one pair even nested deep inside an English coal mine.

   Red foxes may use Earth's magnetic field to aim their famous pouncing dives — they prefer striking toward the northeast.
