Distribution maps and minimum abundance estimates for wintering auks in the Bay of Biscay, based on aerial surveys
National audience The “Erika” oil spill has killed more seabirds than any before in Europe: nearly 70 000 guillemots (Uria aalge) were found dead or alive on beaches, and many more are thought to have been killed. This unexpectedly high number highlighted how poor our knowledge was on spatial and te...
