🔊 This the season! Looking or two MSc students to tackle
1. vocal efficiency across pipit species
and, surpsingly,
2. vocal tract anatomy of the great cormorant (bonus: I also have the heads to model hearing!)

Drop me a line! I love people! :)

Finally, I presented a poster on “Vocal divergence and incipient speciation in the Reunion Grey White-eye” during the last poster session of the conference. It was my first time presenting this part of the project, and what a pleasure it was!

🎤 I also had the chance to present part of my PhD work “The role of song in population divergence: Insights from the La Palma’s Canary Islands Chaffinch” 🐦
Great to share these results and get feedback!

It was a real pleasure to co-organize this symposium with Maëva Gabrielli and José Cerca @naturalselection.bsky.social 🙌

Yesterday we had our symposium “Evolution in Small Populations” at #ESEB2025 🎉
It was a fantastic session, and we’re very grateful to our invited speakers, Hernán Morales ‪@hernmoral.bsky.social ‬ and Eva Ringler, for their amazing talks 👏

Do birds tune their songs to their hearing?

Is there tight coevolution between avian vocal signals and hearing-or do signallers and perceivers evolve more loosely?

It turns out perfect tuning is not required...

Acoustic monitoring is everywhere this days. But how far can we really detect a bird acoustic within a tropical forest? 🧐🎙️
To answer this questions we built sound attenuation models for two Neotropical birds and estimated they detection ranges.
