Common Murre (Uria aalge)
Context
An extreme marine heatwave linked to climate change devastated Alaska’s common murre (Uria aalge) population, wiping out nearly four million seabirds — about half of their global numbers — over a three-year period.
About
- Common murres are long-lived diving seabirds that inhabit temperate and subarctic marine ecosystems in the Northern Hemisphere.
- They feed on small schooling fish, juvenile predatory fish and krill, diving as deep as 200 metres to forage.
- Common Murres are dapper, black-and-white seabirds that nest in raucous throngs on crowded sea cliffs.
- Often described as "flying penguins," they have a tuxedoed look but are actually relatives of auks and puffins.
- Habitat: It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands.
