Rusting rivers and huge rainfall have complicated pollution control at Northwest Alaska’s massive Red Dog zinc mine. (via Northern Journal) www.adn.com/alaska-news/...
Thawing permafrost is causing trouble for the Red Dog mine. Solutions could be costly.

Today's #BirdOfTheDay theme is #BirdsOnTwigs. My contribution may be disqualified as the judges could rule this Bohemian Waxwing is under the twig. They are back again for the winter so I'll try to do better. Anchorage #Alaska 🪶

Off coastal #Argentina Kelp Gulls have developed the habit of eating the skin off the backs of Southern Right Whales. I wonder if whales resting on their backs (like this one) or in the yoga pose of yesterday's post is a response by the whales to reduce the bites? 🦑🦊🪶

We don’t see them every winter, but in an irruption year, they come down from the Arctic and spend some winter time with us!

No Shakespeare but some drama. An important tree to these American Three-toed Woodpeckers. It seemed to mark the boundary between their patches of the burn. Wing flashing and sky pointing ensued when they came near. Anchorage #Alaska #WoodpeckerWednesday 🪶

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

Manx Shearwater recently arrived in the South Atlantic and already well into molt. Seems most places I go the common shearwater is in the opposite hemisphere from which it breeds and not looking their best. 🪶 Off #Argentina #seabirdSaturday

As it's breeding time for giant petrels on Bird Island, meet the oldest female giant petrel on the island ⬇️
She hatched there in 1989, making her an impressive 36 years old.
This season, she decided to build her nest next to the path, where the team greet her every day as they go past 🪶

After being declared extinct twice(!), it was on this day in 1948 that the Takahē (Porphyrio hochstetteri) was rediscovered again. Thanks to intensive conservation work there are now more than 500. www.doc.govt.nz/our-work/tak...
The incredible takahē story
Thought to be extinct not once but twice, the takahē's remarkable story of survival and rediscovery is a testament to the resilience of nature.

Black-backed Woodpecker. This woodpecker really likes burns and colonizes them remarkably fast once the flames die out. We haven't had a suitable fire for a few years so now it takes a lot of looking to find this fine bird. Anchorage #Alaska #WoodpeckerWednesday 🪶
