Animal Behavior

Animal behavior, a fundamental discipline within zoology and biology, is the scientific study of the vast array of actions and responses exhibited by animals. It investigates how and why animals interact with each other and their environment, encompassing everything from foraging and migration strategies to complex social structures, courtship rituals, and communication. Researchers in this field explore both the proximate causes of behavior—such as the underlying genetic, hormonal, and neurological mechanisms—and the ultimate causes, which relate to the evolutionary pressures and adaptive advantages that have shaped these actions for survival and reproductive success.
