Thousands of dead puffins wash ashore
In recent weeks, thousands of dead puffins have washed ashore on European shores. The birds are killed in storms at sea. A biologist believes that the Icelandic breeding population is likely to decline.
A tagged puffin that had been breeding in the Vestmannaeyjar Islands recently washed up dead on a beach in Portugal. It is one of thousands that have washed up on shore in Europe in recent weeks.
Tens of thousands of bird carcasses have washed ashore in Portugal, France, Spain and the UK since January, the majority of which are puffins. This has been reported by the BBC , among others.
"This is not that uncommon, it happens all the time. But what people are really worried about is that the frequency of storms, and especially how long they last, is increasing in the wake of warming," says Erpur Snær Hansen, a biologist who has studied puffins for decades.
The birds die in prolonged storms at sea. "What people think happens is that in the turbulence that occurs in these storms, the food sinks from the surface and then it is more difficult for these divers to reach the food. They have to work harder to reach the food and end up not getting enough to stay alive, the poor thing," says Erpur Snær.
The birds they tagged have mostly been found breeding in Scotland, but Erpur says he has received a report of one bird from the Icelandic breeding population.
"It just so happened that I received a recovery report that one bird that was tagged here in Stórhöfði in the Vestmannaeyjar Islands washed ashore in Portugal. So some marginal percentage of our birds are there in this area."
Erpur says the Icelandic breeding population, which is larger than the Scottish one, remains further west and in a larger area of water than the birds that have been washing ashore in Europe.

"The bulk of our bird's distribution is in a much larger area and more oceanic west of Europe. On the other hand, we don't know the size of these carcasses because they are so far out to sea that these carcasses never reach land, as is currently happening in Europe."
Are you worried that this could be a blow to the Icelandic stock?
"Yes, this could very well be the case. One is particularly concerned now that the frequency of these storms is clearly increasing."
😭😱
Many are surprised that I talk about natural climate change – yes, it exists ... as a "pure" one and as a very large consequence of, at some points very small, man-made things.
Here is one of these consequences
