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.
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.

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.
Though the risk to humans is low, scientists warn that outbreaks among farmed birds increase the potential for the virus to mutate and pose a threat to humans.
Since July 1, more than 460 dead seals have washed up on beaches and islands in Maine, New Hampshire, and northern Massachusetts. Another 137 have stranded themselves, overwhelming marine animal rescuers.
As the number of dead or stranded live seals washing up along the coast from northern Massachusetts to southern Maine continues to increase dramatically, marine mammal experts are considering influenza or environmental pollution as potential explanations.
