Vulnerability and breeding ecology of the black guillemot in the Baltic Sea region

Aim: to assess the (future) vulnerability and the breeding ecology of the black guillemot (Cepphus grylle), a threatened seabird in the Baltic Sea region.

Project description: The black guillemot (Cepphus grylle) is a seabird species with a circumpolar distribution. One of the southernmost populations occurs in the Baltic Sea and is currently endangered. Climate change is thought to have additional negative effects on the species. The aim of this project is therefore to evaluate the future vulnerability of this locally endangered seabird by assessing the impact of climate change on its geographic distribution, globally and locally in the Baltic Sea region. The project simultaneously assesses how climate change may affect the availability of prey, using sea productivity as a proxy. A secondary aim of the project is to obtain a more comprehensive understanding of the breeding ecology of the black guillemot, using extensive field based observations, and camera traps set up in black-guillemot colonies on islands groups in the Baltic Sea. This knowledge can aid nature conservationists in identifying actions and regions that need conservation priority.

The project is conducted in close collaboration with the Ume River Delta Field Station (

Funding: King Carl XVI Gustafs 50- years fund for Science, Technology and Environment award.
