💁🏻‍♀️ TIL: Researchers traveled to remote #Boé National Park in #GuineaBissau to study accumulative stone throwing, a rare behavior where male western #chimpanzees repeatedly hurl #rocks at specific #trees while calling out and drumming. 🌳

The team used camera traps to gather #data on what these chimpanzees might be communicating, and whether the behavior is a form of #animal #culture. Some sites have been used for over a decade. 🐒

💁🏻‍♀️ TIL: A Japanese biologist noticed in 1997 that #humans are the only #primates with clearly visible white sclera. 👁️

Researchers have since shown this trait helps us follow each other’s gaze – a key building block for collaboration, #language development, and social bonding. 🤝

New research shows chimpanzees learn survival skills via social culture—observing, copying, and passing knowledge across generations. Culture may not be as uniquely human as once believed.

🐋🪞 In a new study, two #beluga #whales at a #NewYork #aquarium showed possible self-recognition in a mirror – one even pressing a mark behind her ear against the reflective surface.

The results place belugas alongside #chimpanzees, #dolphins, #elephants, and maybe #magpies on a short list of species that pass. But scientists disagree on what the test actually proves, and the debate itself raises deeper questions about animal #consciousness.

Social learning in wild #chimpanzees 'wild chimpanzees use peering, i.e. the close-range observation of a conspecific, for targeted social information seeking. We then show that chimpanzees peer at a wide range of everyday skills, such as feeding and grooming, and direct peering toward various conspecifics from an early age'

Spring is here and the Cincinnati Zoo is full of new life, from frolicking bear cubs, to clingy primates, and oh, the not-so-huge manatee!
