Mergule nain, "Alle alle", Terre de Liverpool, Groenland Est. Ce petit oiseau est un bon indicateur du climat car en prise directe avec la variabilité environnementale. D'un poids de 150 grammes environ, il se nourrit de copépodes, un crustacé planctonique. Plus la mer est froide, plus ces copépodes sont gros, riches en lipides et faciles à attraper. En conséquence, si les eaux se réchauffent, le mergule aura plus de mal à se nourrir lui et ses poussins.
