Four Decades of Change:
An Arctic seabird responds to a warming Arctic
Mandt’s Black Guillemot (Cepphus grylle mandtii) is a true Arctic seabird, utilizing the marginal ice zone throughout the year and leaving the Arctic Basin only when ice cover is nearly complete in winter. Since 1975 the phenology, breeding success, diet and adult survival of the species has been studied annually at Cooper Island, in Arctic Alaska. Annual temperatures in the region have increased by >3°C during the study and the Cooper Island research has been able to document the response of an Arctic marine upper trophic level predator to the unprecedented changes occurring in snow and ice habitats in a warming Arctic.
