A bit late to the #ISBE2026 posting brigade, I had to recover from the inspiring talks, old and new friends, parties… I presented the latest results from @jpartecke.bsky.social’s cross-continent migration experiment on 🐦‍⬛. Curious? Stay tuned.. 👀 @isbe2026.bsky.social @animaltracking.bsky.social

How 'inseparable' are partners? 📍🐦 Using fine-scale automated radiotracking we found that chirruping wedgebill breeding partners stick extremely close — they occupy almost identical spaces and follow each other continuously during AND after breeding. Check it out ➡️ doi.org/10.1093/behe...

Just got back from Ny-Ålesund, the northernmost town in the world, to catch and track Arctic terns for @seatrackscience.bsky.social in collaboration with @maartenloonen.bsky.social. I love coming to this place, and I love the terns. They probably did not like me so much though...

🔊🔊 What's important in a duet? In a new paper, we tested whether duet coordination in pairs has a function in their territoriality, using fine-scale and coarse measures of duet coordination in response to playback in chirruping wedgebills. See 👉 doi.org/10.1111/eth.... @marcnaguib.bsky.social

Broken families can have huge effects on children, even later in life. But is that the case in species other than humans? Read my latest article in the ‪@aunz.theconversation.com‬ on mate switching effects in offspring of the ‪@seychelleswarbler.bsky.social‬ 👇 theconversation.com/the-chicks-a...

Parental separation in humans can deeply affect children. But in another monogamous pair-bonding species, it has no such effect.

We humbly interrupt your scroll to bring you the news that Wisdom—the world's oldest known wild bird—is breeding again, age 74. Go on girl. 😍
A screenshot of a social media post from USFWSPacific that reads:

"SHE DID IT AGAIN!  

Wisdom, the world’s oldest known wild bird, is back with a new partner and just laid yet another egg.  

At an approximate age of 74, the queen of seabirds returned to Midway Atoll National Wildlife Refuge last week and began interacting with a male."  

This tweet is paired with an image of two Laysan Albatrosses at Midway Atoll National Wildlife Refuge. Wisdom, the oldest known wild bird, is shown alongside her new partner, demonstrating her enduring legacy as a remarkable seabird.
