This document discusses the field of animal behavior and its importance and applications. It notes that animal behavior is the study of how animals interact with each other and their environment, and serves as a bridge between physiology and the environment. It then outlines several ways in which the study of animal behavior contributes to and influences other fields, such as neuroscience, environmental management, human behavior studies, and conservation. Specific examples are given of insights gained into areas like communication, emotional expression, migration patterns, and pest control from animal behavior research. The document also discusses how animal behavior courses can increase scientific literacy and interest in biology.
