‘Sex reversal’ is surprisingly common in birds, new study suggests
Survey of five Australian avians finds numerous discordant individuals, including a genetically male bird that had laid an egg

An analysis of 35 hours of footage from 15 birds 🐦, published on August 18 in the journal Current Biology 📖, shows that Streaked Shearwaters (Calonectris leucomelas) were pooping 💩 every four to 10 minutes, an average of five times per hour, losing perhaps 5 percent of their body mass.

Primates’ same-sex sexual behaviour ‘may reinforce bonds amid environmental stress’ 🌍💞. Behaviour among non-human species could help keep groups together in face of social challenges, says study. Same-sex sexual behaviour was found in 59 non-human primate…
🐒 Same-sex sexual behaviour in primates is widespread, seen in 59 species like chimpanzees and gorillas, suggesting ancient evolutionary roots or multiple independent origins.
🌿 It's more common in species facing environmental stress, such as drier climates with scarce resources and higher predator risk.
🤝 This behaviour appears to strengthen bonds, reduce tension, and help societies navigate challenges.
🐒 The study suggests early human ancestors may have also exhibited similar behaviour due to comparable societal pressures.

A global screen for magnetically induced neuronal activity in the pigeon brain
How animals detect Earth’s magnetic field remains a mystery in sensory biology. Despite extensive behavioral evidence, the neural circuitry and molecular mechanisms responsible for magnetic sensing remain elusive. Adopting an unbiased approach, we used ...

Elephants communicate through ground vibrations thanks to large middle ear bones and a special muscle Read Full Article #ElephantCommunication #Infrasound #AnimalAcoustics
🐘 Elephants possess a unique auditory advantage: larger middle ear bones and a special muscle that significantly enhance their ability to communicate through ground vibrations, extending their reach up to 10 kilometers.
👂 This enhanced bone-conduction hearing allows elephants to perceive low-frequency vibrations more effectively than humans, thanks to middle ear bones that are nine times heavier and eardrums seven times larger.
🎧 The ability to voluntarily close their ear canals may boost their low-frequency hearing by up to 30 times, a capability humans lack, potentially improving their reception of infrasonic frequencies.
