Coastal divers

This group consists of diving sea birds that are bound to coastal waters all year round. The species in this group show similar behaviour to the pelagic diving seabirds and also have high vulnerability.

Species within this group:

  • Black Guillemot (Teist)
  • Black Scoter (Svartand)
  • Black-throated Loon (storlom)
  • Common Eider (Ærfugl)
  • Common Loon (Islom)
  • Common Merganser (Laksand)
  • European Shag (Toppskarv)
  • Goldeneye (Kvinand)
  • Great Cormorant (Storskarv)
  • Great crested grebe (Toppdykker)
  • Heron (Gråhegre)
  • Horned Grebe (Horndykker)
  • King Eider (Praktærfugl)
  • Little Grebe (Dvergdykker)
  • Long-tailed Duck (Havelle)
  • Red-breasted Merganser (Siland)
  • Red-necked Grebe (Gråstrupedykker)
  • Red-throated Loon (Smålom)
  • Steller´s Eider (Stellerand)
  • Tufted duck (Toppand)
  • White-winged Scoter (Sjøorre)
  • Yellow-billed Loon (Gulnebblom)





















Highly sensitive to oil pollution. Losses may be difficult to assess, as birds that are oiled at sea may sink. 

Oil on the feathers leads to loss of insulation, flotation and water proofing properties of the plumage. The high vulnerability of the diving species is due to a lot of time on the sea surface and thereby being dependent on intact plumage.
