Scientists investigate the cause behind dying pelicans in California

A mysterious die-off of brown pelicans along California's coast has scientists puzzled and searching for answers as hundreds of the birds have died or required rescue.

Dino Grandoni reports for The Washington Post.

In short:

Nearly 900 brown pelicans have been found dead or debilitated along California’s coast, raising concerns among biologists.
Initial tests ruled out avian influenza and domoic acid poisoning, with starvation emerging as a potential cause.
Scientists are exploring theories like deeper fish due to warmer waters but caution that more research is needed.

“I tend to think of the old canary in the coal mine. It’s now the seabird in the ocean.”

Why this matters:

The unexplained deaths of these pelicans could indicate broader environmental issues in California’s coastal waters. Understanding the cause is vital for protecting both the pelican population and the health of marine ecosystems.
