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.

I would really appreciate help processing this.

The bird is sick, bird dies, bear eats bird, bear dies.

It shows that this particular influenza strain can infect both bears and birds.

Wash your hands, stay home if you're sick, don't eat birds that have died from influenza.

Ok, but... polar bears eat birds?

[–] Kalkaline@leminal.space 28 points 2 years ago (1 children)

Polar bears aren't picky where their calories come from and they need a lot of them.

[–] girlfreddy@lemmy.ca 8 points 2 years ago

Also we should take into account the lack of sea ice which means the bears can't hunt marine food sources.

Yes, pretty much anything that is available.

Polar bears have evolved to prey on seals. But they are curious and will eat other foods when available — including geese, bird eggs, whales that wash up on the beach, and even the occasional small mammal.

If only AI summaries were half as good as this.

And if you're a bot... fucking bravo.

Not necessarily; while ripping the bird apart to eat it, if blood and whatever other residues get on/in soft tissues like nose or around eyes, infection spreads easily that way.

[–] Z3k3@lemmy.world 8 points 2 years ago (3 children)

Polar bears are birds.

In seriousness I don't know if this is fucked up or just something that happens sometimes.

[–] Jaderick@lemmy.world 9 points 2 years ago

Viruses can jump between species , especially if their target proteins are non-specific. It’s not necessarily rare, but nonetheless destructive.

[–] OpenStars@discuss.online 2 points 2 years ago (2 children)

Lol, polar bears aren't real. :-P

[–] Z3k3@lemmy.world 6 points 2 years ago

Wait I thought birds wer.... ohhhh

[–] I_Miss_Daniel@lemmy.world 4 points 2 years ago (1 children)

That might be true in the future.

[–] OpenStars@discuss.online 5 points 2 years ago

Gulp, like anyone I do enjoy being right, but dayum in this case I very much hope that I am wrong!?!? :-P

[–] quindraco@lemm.ee 4 points 2 years ago (1 children)

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".

[–] FlyingSquid@lemmy.world 2 points 2 years ago

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.
