Summary:
- The article discusses the plight of the common murre, a seabird species that experienced a catastrophic die-off event in 2015-2016 along the Pacific coast of North America.
- Scientists say the common murre population has not recovered from this "worst single species mortality event in modern history," with the population remaining at a fraction of its pre-2015 levels.
- The die-off was linked to a combination of factors, including ocean warming, harmful algal blooms, and a lack of available prey, highlighting the vulnerability of seabird populations to the impacts of climate change and environmental disruptions.
