The common murre, a large black-and-white seabird native to northern waters, has become far less common in Alaska over the past decade due to the impacts of climate change.- Climate winners and losers - The marine heat wave didn't just impact common murres.

Marine heat waves have halved Alaska’s common murre population. A study links these declines to food shortages.

About four million common murres were killed by a domino effect of ecosystem changes, and the population is showing no signs of recovery, according to new research.

Researchers say the common murre die-off was “the largest documented wildlife mortality event in the modern era.”

Murres, a common seabird, look a little like flying penguins. These stout, tuxedo-styled birds dive and swim in the ocean to eat small fish and then fly back to islands or coastal cliffs where they nest in large colonies.

In what is considered the largest documented wildlife mortality event in the modern era, a heating ocean wiped out half of Alaska’s common murre seabird population, a new study found. Scientists have noticed an increase in marine heatwaves,
