Nest-site attendance and foraging ecology of the Northern Fulmar (Fulmarus glacialis) on the Faroe Islands. Is the Northern Fulmar a useful indicator of ecosystem productivity and pollution?
The Northern Fulmar (Fulmarus glacialis) is one of the most abundant seabirds in the Northern Hemisphere and the most abundant seabird on the Faroe Islands. Except from a few sporadic observations up until the 1950´s no study has focused on this species on the Faroe Islands. Being considered a signi...

The Northern Fulmar (Fulmarus glacialis) is one of the most abundant seabirds in the Northern Hemisphere and the most abundant seabird on the Faroe Islands.
