Animal behavior is the scientific study of the observable actions, interactions, and behavioral patterns of animals, typically investigated within ethology, behavioral ecology, and comparative psychology. It encompasses mechanisms (proximate causes such as neural, hormonal, and genetic control), development (ontogeny and learning), function (adaptive value in survival and reproductive success), and evolution (phylogenetic history and divergence among taxa). Research on animal behavior quantifies activities such as foraging, mating systems, parental care, communication, social organization, and antipredator strategies, often integrating experimental, observational, and modeling approaches to understand how behavior emerges from organism–environment interactions and contributes to fitness and ecological dynamics.
Every evening, as they move from place to place through the forest, chimpanzees stop to build a nest—most often in a tree—to sleep in. Using a selection of branches, leaves and twigs, they create comfortable and safe spaces ...

Diving is physiologically challenging for marine animals. Long and deep dives can trigger "anaerobic" (oxygen-less) metabolism in organs other than the heart and brain that causes lactic acid to accumulate. Even though diving ...

Birds sing the most about an hour before dawn, when the air is at its stillest. Theoretically, this enables sounds to travel farther, making song up to 20 times more effective than if sung at midday.

Every day, millions of people watch their pet reptiles run, dig, swim or climb up against the walls of their enclosure. Reptile keepers call this "glass surfing," but among scientists, this conduct is typically considered ...

Dogs have long been known to have smaller brains than the wolves they descended from. But when they started to shrink has been a matter of some debate. New research published in the journal Royal Society Open Science, which ...
An international team of researchers have made the surprising discovery that urban birds—such as great tits, house sparrows and blackbirds—flee sooner when approached by women compared to men. But they don't understand why. ...
