"I've sometimes been accused of degrading mankind, or insulting human dignity, of making man beastly"
"This surprised me because I like animals and I feel proud to call myself one. I've never looked down upon them, so to call human beings animals is not, to me, degrading."

Nice end to a fun PhD 🎉
SPAR supermarkets are promoting a broom and stick set in Austria with Veronika.
It reads:
“Einstein among the cows: Spar sells Vroni's back scratcher set”
Vroni is the diminutive form of Veronika, of course.
Thanks to Özge Nasa for the tip!

Had our official launch of the Avian Research Association of Austria (ARAA) yesterday, and I’m so pleased it went well! This is the planned culmination of the regular research pub socials I started back in 2023, it’s hard to believe it’s finally happened 🥰 I have such a great team!
1/2 Veronika in winter continues to leave us speechless.
Now there are no annoying horseflies or bites to scratch, but it's time to get rid of the winter coat, and there's nothing better than a good stick with sharp edges.

After a rough year, I’ve just had the best two days of my life. I successfully defended my PhD, got a job as a postdoc, and received a signed copy of a book (and an acknowledgment) by one of my favourite authors @aptshadow.bsky.social 😍🙌🥳
Application review begins in one week (Mar 16)!
(Review will continue until all spots are filled.)
So incredibly happy that the work on Tanimbar will continue - it’s such an amazing lab. 🥹
Huge congrats to everyone, well deserved!
Honoured to be among such great colleagues @barbaraklump.bsky.social @christophvoelter.bsky.social @auersperga.bsky.social and Justus Piater, to study fundamental drivers of innovation. And hugely grateful to the @fwf-at.bsky.social to be able to continue the fieldwork on the Tanimbar Islands 🌴🕊️🤠
Fantastic!!! Congratulations!!!

Ze Frank is the best, and "the Goffin's cockatoos make the New Caledonian crows look like Old Caledonian crows" (this it's an actual comment on YouTube!)
Don't miss this video about our work at the Goffin Lab (and the Tanimbar Lab!)

Is dogs’ tendency to follow human misleading communicative cues influenced by humans’ auditory perspective?

Cow cognition might have been underestimated, but check out this exciting study by @biotay.bsky.social and @auersperga.bsky.social. Perhaps they do deserve more credit in the field of animal cognition than they have been given 🧹🐮
✨New paper✨
How do juvenile ravens find social groups?
We describe how juvenile common ravens, who have left their natal territories seeking to join non-breeder flocks, use space with respect to other birds, and discuss what this means for social integration.

An amazing feat of work! Can't wait to follow up on this ;) Big congrats! 👏🏻👏🏻
I had the honour of working to bring @auersperga.bsky.social’s baby to life. It’s a VERY heavy baby - over 200 references (and yes I read them all) - but necessary to do justice to our new hypothesis of combinatory tool use origins 📝👶🛠️
