Psychoanalysts who study animal behavior are far too exclusively interested in the 'neuroses' of animals and they rely too much on studies of domesticated animals. Observations of normal animals in their habitat shed more light on some of the problems of psychoanalytic theory, especially the Triebtheorie. Lampl aptly defends these theses of his by reporting and discussing stimulating facts which are presented in a book by Konrad Lorenz: Der Kumpan in der Umwelt des Vogels (The Partner in the Environment of Birds). The facts selected refer to the 'fixation' of the newborn bird to its mother, the feeding pattern, the reaction to loss of the partner, 'activity' in mating and communications among birds.
