Mine and Bob’s first trip to St Just, Cornwall, and it didn’t disappoint.
Highly recommend for any bird enthusiasts!

#Rewilding is new & it can be hard to find funding for it, especially if you are exploring a new idea or approach. You have just over a month to apply to Rewilding Britain's innovation fund for up to £15,000 to progress your rewilding project.

Cool paper from the Askew Lab.
jexpbiol.bsky.social Journal of Experimental Biology @jexpbiol.bsky.social · Dec 20
Read this month's Editors' Choice 'The contractile efficiency of the mantle muscle of European common cuttlefish (Sepia officinalis) during cyclical contractions' by Nick Gladman and Graham Askew journals.biologists.com/jeb/article/...
Cartoon of a cuttlefish thinking, ' My mantle muscle is fantastically efficient, but I'm cumbersome, so I require a lot of power to move around'.

These little fellas on Lindisfarne approached me like I owed them money. Learned a valuable lesson today after patiently waiting - northerners don’t share pies.

My first PhD chapter just got published in @jexpbiol.bsky.social ! We proposed a new framework to estimate foraging energetics ⚡ of Adélie 🐧 using TDRs. Our framework provided results similar to accelerometers and could likely be applicable on other diving predators 🐋🦈
