Composition of chick meals from one of the main little auk (Alle alle) breeding colonies in Northwest Greenland
During the last decade, increasing information on little auk (Alle alle) biology, ecology and behaviour has been reported. However, only a few of these studies have focused on the breeding population in the Avanersuaq (Thule) district of Northwest Greenland, where 80 % of the global little auk popul...

During the last decade, increasing information on little auk (Alle alle) biology, ecology and behaviour has been reported.
