A polar bear has been killed by bird flu as the highly contagious H5N1 virus spreads into the most remote parts of the planet.
The death was confirmed in December by the Alaska Department of Environmental Conservation. “This is the first polar bear case reported, for anywhere,” Dr Bob Gerlach, Alaska’s state veterinarian, told the Alaska Beacon.
It was found near Utqiagvik, one of the northernmost communities in Alaska, two years after this latest strain was detected in North America. Gerlach said it was likely the bear was scavenging on the carcasses of infected birds.

The current outbreak of the highly infectious variant of H5N1 – which started in 2021 – is estimated to have killed millions of wild birds. Globally, thousands of mammals have also died of the virus, including black bears and brown bears. Bald eagles, foxes and kittiwakes are among the species to have died of the virus in Alaska in recent months.
If the bird flu can penetrate the Arctic it can penetrate the Antarctic. If that happens we’ll lose a lot of penguins, far more than we can “afford”.
A lot of penguins aren’t in the Antarctic, so it may already be spreading through populations in places like South Africa and the Galapagos Islands.
