Coastal diving seabirds
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 have the same high vulnerability.
- Cormorants/Shags (skarv)
- Black Guillemot (Teist)
- Common Eider (ærfugl)
- Some duck species (noen andearter)
- Divers, Loons (Dykkere/Lommer)
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.
