Ethology
The scientific study of animal behavior in the natural habitat is known as ethology. Though initially thought to be restricted to non-human beings primarily due to the works of Tinbergen and Lorenz from the 1920s, it can be quite inclusive of humans as well, some of whom tend behave more 'like animals' than any animal ever has. Removing the animal-human barrier is one of the most intelligent actions any human can take, for doing so permits the recognition and merging of the best qualities of all species.
