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

Interesting to compare w/quoted @friggspeelman.bsky.social study

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

New preprint out with @hannahdugdale.bsky.social, @lummaalab.bsky.social, and @erikpostma.bsky.social: www.biorxiv.org/content/10.1...
Why do we age? And can a “natural experiment” during the Great Finnish Famine with long-term data help provide some answers?

This work is co-authored by @hannahdugdale.bsky.social, David Richardson, Jan Komdeur, and Terry Burke

Then, we studied divorcing using long-term data of @seychelleswarbler.bsky.social addressing all these shortcomings, and found that divorce is related to male age, pair-bond tenure, and reproductive success, but that there are no strong fitness consequences to divorce
friggspeelman.bsky.social
We addressed 5 shortcomings: (1) divorcees and widows and (2) initiators and victims of divorce are not disentangled, (3) consequences of divorce and widowhood are not studied together (4) long-term consequences and (5) age-dependency of divorce are not addressed

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.
