Cool study suggesting acoustic similarity ≠ perceived meaning! Most studies cluster vocalizations by acoustic features. This one tested toddler vocalizations (distress, contact, begging) finding acoustic space and perceptual space don’t always align. www.cell.com/current-biol...

The challenge of decoding animal communication using AI
Animal communication studies often classify signals by their physical similarity, assuming it reflects how animals perceive meaning. Using vocalizations of pre-linguistic toddlers, Taub et al. show that acoustic similarity does not necessarily correlate with the receiver’s perceptual space, highlighting a key challenge in interpreting animal communication systems.

Bafflingly there are still people out there in the world who think being passionate about nature is “kind of weird”. or “a niche interest”. These people have it all wrong. Nature isn’t some quirky sideline to the main business. It IS the main business.

South American Indians developed a technique of color modification of the feathers on living birds, called tapirage 🤯 They took young parrots, plucked their feathers, and smeared the bald spots with frog blood to which "certain other substances were added." The new feathers grew in yellow.

Scientifically speaking: birds are weird little dudes. Let's talk about "anting" & why all the cool birds at school are doing it. The history goes back to ornithologist John James Audubon, who documented young wild turkeys "wallowing" in anthills in 1831.
