The key-site report from SEAPOP summarises the monitoring results from the 2019 breeding season and presents detailed insights into population trends, breeding success and adult survival rates of each monitored species on every key-site in Norway.

Poor production

A large number of Norwegian seabird populations struggle with poor and variable breeding success. The pelagic species fared better than the coastal species in 2019, but overall the 2019 breeding season was poorer than that in 2018. Herring gulls and common eiders stood out with the poorest reproduction in most of the monitored colonies. Northern gannet and glaucous gull, which are only monitored at two sites each, were the only species to perform exclusively well in 2019.

Disconcerting population changes

Many of the monitored populations decreased from 2018 to 2019, with particularly worrying declines among common eiders, black-legged kittiwakes and razorbills. The long-term population development is also alarming, with most of the Norwegian seabird populations having declined over the last decade. The species with the most positive trend is the great skua.

Most of the black-legged kittiwake populations declined in 2019. On Spitsbergen, the breeding population was reduced by 30% since 2018.
