As we now know, birds are the last surviving dinosaurs.
What we don’t know is whether dinosaurs already produced such elaborate songs as our birds do today.
If they did, they might have sounded like this — similar to birdsong, only lower and slower; after all, they were much larger.

We hear a recording made on May 13, 2025, just before sunrise, here in the forest on the grounds of Symposion Lindabrunn.
By slowing it down to 12% of its original speed, the “dino-birds” sound as if they were underwater, immersing us in a world of strange beauty — a world that invites us to linger.
After a while, an airplane passing — even that doesn’t disturb much.
