  4. a The Irish Mute Swan population has been elevated to biogeographic population [21], and the threshold is thus the same as that for all-Ireland.
  5. bAdditional birds from feral population - c. 2,000 individuals.
  6. cThe relevant population on which to base the 1% threshold for Common Eider has been taken as the NW European total which comprises the four populations in this region (Britain/Ireland 73,000, Baltic/Wadden Sea 850,000-1,200,000, Norway/NW Russia 300,000-550,000 and White Sea 20,000-30,000).
  7. dThe relevant populations for Common Redshank include two populations, robusta (breed in Iceland and the Faeroes, winter Britain, Ireland, NW France) and brittanica (breed in Britain and Ireland, winter Britain, Ireland, NW France).
