duck, duck, …magnetic duck

“Mallards in tight formation tends to face either north or south when landing. Because vision alone cannot prevent collision between these high-speed flyers, the ducks use sensors in their eyes, beaks and ears to align themselves to Earth’s magnetic field.” Nature, vol. 531, 31 March 2016
