Marine Heatwave Linked to Dead Seabirds Along California Coast
Marine Heatwave Linked to Dead Seabirds Along California Coast
US · Published May 19, 2026
A significant increase in dead and emaciated seabirds has been observed along California's coastline, with experts attributing the phenomenon to a marine heatwave.
According to the Los Angeles Times, ocean temperatures have risen 4 to 8 degrees above average in some areas, disrupting the marine food web.
Species such as Brandt’s cormorants, loons, common murres, and grebes are among the most affected.

Why It's Important?

The ongoing marine heatwave poses severe risks to seabird populations along the California coast. Juvenile birds are particularly vulnerable, with starvation identified as a primary cause of death. The disruption in the food web has cascading effects, leading to increased competition for limited resources. Wildlife rescue centers have reported a surge in injured and malnourished birds, some suffering from fungal infections due to weakened immune systems. The ecological imbalance could have long-term consequences for marine biodiversity and the health of coastal ecosystems.
