Fun facts

  • GeneralThe males perform a roller-coaster display flight of zigzagging dives.
  • It has exceptional hearing for a diurnal raptor, thanks to a facial disc like an owl's that lets it locate prey hidden in the grass.
  • Because it nests on the ground in crops, mechanised cereal harvesting kills unfledged chicks every year; in Catalonia its conservation has depended on locating the nests and leaving the area around them uncut.
  • The Spanish population marks the southern limit of its Palaearctic breeding distribution.
