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 🪶

B.C. wolves use line to pull up crab traps in first possible tool use by species
Researchers have captured video footage of wild wolves in British Columbia pulling crab traps out of the sea by their lines to eat the bait inside, in the first evidence of possible tool use by the animals.

A familiar bird in many parts of the world, this Barn Swallow was thinking outside the box and foraging at sea off of #Argentina. Presumably a migrant heading to its second summer. 🪶

55 years ago today, the Oregon State Highway Division had a whale of a problem on its hands. How it solved it is the stuff of legends.
In other words: Happy Exploding Whale Day!

I'm recently back from an excursion to the opposite end of the world so for awhile most of my posts will be from the southern hemisphere. I'll start with the aptly named Yellow-chinned Spinetail, a lifer (@aba.org ) seen during a stopover in Buenos Aires #Argentina. 🪶

There was frost on the pumpkin when I took this shot but we had a dump of snow overnight so I'll have to try and relocate this bull to photograph him in the snow before he drops to a lower elevation. Chugach State Park #Alaska 🦊

I don't see Redheads on land very often, perhaps this guy didn't have much else to do while he finished molting. Perhaps that should be moulting as I saw this guy earlier this fall in Burlington #Ontario 🪶
