The American woodcock has a peculiar way to rustle up earthworms - it rocks back and forth as it walks!
People think that the American woodcock's peculiar bobbing walk is a form of worm grunting, as vibration of the soil encourage worms to surface (presumably because the vibrations are similar to those produced by digging moles that eat them - so the worms are trying to escape their feared predator).
