New paper! My PhD student Ali Moayedi explored how geese use geomagnetic, wind, and solar cues to navigate & revealed flexible multi-sensory strategies in real conditions. With @jedalong.bsky.social, @fbenitez.bsky.social, Andrea Koelzsch and Helmut Kruckenberg. www.sciencedirect.com/science/arti...

All the puffins on the Isle of May today. So many puffins -apparently there are 52000 breeding pairs on this small island!

#FensterFreitag is a thing on Mastodon, but I think we should start it here too. Every Friday post a photo of a window or windows or a view/things you see through a window.

And I think this arc that goes through Orion is a SAR arc, is it, @vincentledvina.bsky.social? This was to the south, while the main aurora was to the north. It persisted for at least 30 min after the main aurora faded. I've never seen one of these before, so no idea if I am right?

Here it is in St Andrews. Very big, stretching to and over the zenith, but not very bright, only visible as pinkish and white haze.

Aurora in St Andrews, as green and pink slow arch, but colours only visible to the camera. To the eye it looked like white mist. #aurora

Amazing #aurora, first in the south, then as an umbrella and a corona overhead. Green, pink, purple and blue colours visible to the naked eye. St Andrews, Scotland, 56N. Photos don't capture not even a little part of this, the sky has erupted and you feel so small under the amazing light courtains.

Since everyone is doing this, here is my Google Scholar wordcloud. Pretty spot on, but slighltly skewed by one collaborator's work 🤣.
