Ethology

n. study of behavioral patterns of animals in their natural environments

Ethology (from Greek: ήθος, ethos, "custom"; and λόγος, logos, "knowledge") is the scientific study of animal behavior, and a branch of zoology.Although many naturalists have studied aspects of animal behavior through the centuries, the modern science of ethology is usually considered to have arisen as a discrete discipline with the work in the 1920s of biologists Nikolaas Tinbergen of The Netherlands and Konrad Lorenz of Austria. Ethology is a combination of laboratory and field science, with strong ties to certain other disciplines — e.g., neuroanatomy, ecology, evolution. The ethologist, a scientist who practices ethology, is interested in the behavioral process rather than in a particular animal group and often studies one type of behavior (e.g., aggression) in a number of unrelated animals.
