Science has treated same-sex sexual behavior as an “evolutionary conundrum” because it (generally) doesn’t help animals to reproduce, thus ensuring that their genes get passed down and their species ...

Detail that zoochosis can come from a variety of factors, including social isolation, small enclosures, noisy visitors, and lack of enrichment. Explore how zoos are working to reduce zoochosis through ...

Quick Take Scientists have documented same-sex behavior in hundreds of animal species, though it is not considered a required function for specific ecosystem roles. Some researchers suggest that ...

Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to new research. Shrinking animal populations make the study of ...

Researchers model and map how neurons across the tiny brain of a C. elegans worm encode its behaviors, revealing many new insights about the robustness and flexibility of its nervous system. To ...

Never underestimate the mind of a crow. Members of a family of birds that includes ravens, rooks, magpies, and jays, crows have been known to bend wire into hooks to retrieve food; drop nuts in a road ...

A total solar eclipse will be visible in North America today. Animals may start acting weirdly as the moon blocks out the sun. Scientists aren't completely sure how eclipses affect animal behavior.

It's time to stop bickering, accept what science tells us, acknowledge the widespread occurrence of intentional behavioral flexibility, and pay attention to why it has evolved.

WASHINGTON (AP) — When a total solar eclipse transforms day into night, will tortoises start acting romantic? Will giraffes gallop? Will apes sing odd notes? Researchers will be standing by to observe ...

A tiger walks the same worn groove along the edge of its exhibit, like a broken record. A parrot methodically plucks out its own feathers until bare skin shows through. To a casual visitor, these can ...
