Fun facts

  • alimentaciónIt is one of the smallest falcons in Europe, taking small birds in flight in fast, agile low-level chases.
  • It builds no nest: it takes over abandoned nests of crows and other raptors, or scrapes a simple hollow in the heather.
  • On its autumn migration it can cover more than 5,000 km from northern Europe to the south of the continent.
  • First-year birds, especially males, sometimes act as "nest helpers" to an adult pair.
