              here, the owl’s hearing range is not
              all that different from a human’s – it is
              their precision that sets them apart. They
              can discern the position of their prey by
              deducing what ear the sound they’re hearing

              reaches first, and how long it takes for that
              sound to reach the other ear. They measure
              this time with extreme precision, down to
              30 millionths of a second. Based on this
              calculation, they turn their head                                                   Lynx in Slovakia
