Seabirds ring the alarm

The ongoing decrease in seabird breeding success signals the need for management actions to protect the marine ecosystems and reduce the effect of climate change.

Workshop on plastic in seabirds

Large amounts of plastic are adrift in the sea. Most of it is microplastic, some of which often ends up in seabird stomachs. A group of researchers met in Tromsø recently to discuss how to best monitor the amounts of plastic in birds. According to their report from the workshop, samples of regurgitation and faeces will be of interest if such monitoring were to be implemented.

Will scare seabirds from drowning

A new study reveals that between 4 000 and 8 000 seabirds probably drown each year in connection with the coastal gillnet-fisheries in Norway. Researchers suggest scaring the birds as a possible measure for reducing the number of deaths.

SEATRACK moves into a second phase

SEATRACK plans to include new colonies and to deploy GLS-loggers on juvenile birds to deliver data of even higher accuracy and quality.

The concentration of contaminants in great skuas is determined mainly by choice of prey

New research reveals that diet specialization in Arctic seabirds is more important for exposure to contaminants than wintering area or long-range transport.

Climate change threatens the kittiwake – extreme weather and altered prey availability reduce recruitment

Bad weather is bad news, also for the red-listed kittiwake. New research reveals that wind conditions combined with the availability of different prey species are determinants of chick production in this seabird.

Flexibility in the foraging behaviour of the kittiwake may buffer the effect of marine environmental changes

Through its ability to adapt, the kittiwake may be robust to changes in the marine environment, but sufficient foraging grounds near the colonies are a necessity.
