Birds

Species Conservation designation(s) of species Location at which found Conservation designation(s) of location Date of discovery at this location Formerly found elsewhere
Common crane (Grus grus) (see note 1) RDB The
Norfolk Broads
 1979 Yes
Notes
  1. Common crane, although occurring in fluctuating numbers as a scarce spring and autumn migrant through Britain, with occasional individuals or pairs wintering or summering, has only established a single breeding population, in the Norfolk Broads (see
    Cranes in Britain for more details); the species was thought to be quite widespread in the Middle Ages, but the term 'crane' was also often applied to grey heron
    , making a reliable determination of historical status difficult.
