Mass marine animal deaths along Peru's coast linked to early El Niño effects
Thousands of seabirds and numerous sea lions have been found dead on Peru's northern beaches and offshore islands, with investigators attributing the die-off to starvation caused by the emerging coastal El Niño.
Television broadcasts from mid-July displayed thousands of dead seabirds—including pelicans, cormorants, guanay cormorants and Humboldt penguins—strewn across Peru's northern coast and offshore islands. Further south, within the Paracas natural reserve, a large number of sea lions were found dead, appearing severely underweight. The Ministry of Environment promptly ordered a comprehensive investigation, dismissing avian influenza as a factor.
Autopsies revealed empty stomachs containing plant matter not normally part of the animals' diet, leading scientists to conclude that starvation was responsible. Lady Amaro, a marine wildlife specialist, explained that the unprecedented die-off along the country's extensive coastline is among the first observable consequences of a coastal El Niño, a climatic phenomenon that has been forming in the equatorial Pacific. The World Meteorological Organization has warned that this El Niño could reach an exceptional intensity by the end of 2026.
Why it matters
The die-off signals severe ecological disruption from El Niño, threatening Peru's marine biodiversity and fisheries.
