Status of the endangered ivory gull, Pagophila eburnea, in Greenland.
International audience The ivory gull, a rare high-Arctic species whose main habitat throughout the year is sea ice, is currently listed in Greenland as ‘Vulnerable', and as ‘Endangered' in Canada, where the population declined by 80% in 20 years. Despite this great concern, the status of...

International audience The ivory gull, a rare high-Arctic species whose main habitat throughout the year is sea ice, is currently listed in Greenland as ‘Vulnerable', and as ‘Endangered' in Canada, where the population declined by 80% in 20 years.
