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...
The last data chapter of my PhD is out now! 🤩 A highly collaborative effort with Chris Tyson, @marcnaguib.bsky.social, and Simon Griffith.

Congratulations to Dr @friggspeelman.bsky.social who was awarded a PhD yesterday 🎉 @rug.nl on 'Socially monogamous partnerships in birds: Causes, consequences, and pair-bond strength' research.rug.nl/en/publicati... A fantastic achievement!

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.

Broken families can have huge effects on children, even later in life. But is that the case in species other than humans?

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

Most Relatable Paper Title 2025?

Stewart & Kelley find in chestnut-backed antbirds that acoustic features + duet coordination correlate w/body & territory size

Duetting do what now?

@friggspeelman.bsky.social etc al. (incl. @marcnaguib.bsky.social) ask in chirruping wedgebills.

Authors measure response to playbacks of duets, coordinated or un-

Results do not support role for precise coordination

Why do we age? And can a “natural experiment” during the Great Finnish Famine with long-term data help provide some answers?

Why These Little Birds Divorce Despite The Risks
Ditching your partner doesn’t seem to work all that well for Seychelles warblers, even if they keep the house, which may be why not many do it.

🌧️💔🐦 Climate impacts on bird relationships

A new @animalecology.bsky.social study shows high & low rainfall impacts divorce rates in monogamous Seychelles warblers.

Could this signal broader ecological impacts due to #ClimateChange?

Rainfall is associated with divorce in the socially monogamous Seychelles warbler
To the best of our knowledge, our study is the first to show that extreme rainfall increases the prevalence of divorce in a socially monogamous population. Our findings add to the growing literature ...
