An overview of the methods, findings, and theoretical approaches used in the study of animal behaviour, with emphasis on the diversity of behaviour and its causative mechanisms. Psychological processes active during play, imprinting, mating and mate choice, parental behaviour, defense, and communication receive special attention first in lectures and then in student seminars. The course focuses on both adaptive (evolutionary) functions of behaviour and on proximal (psychological, neurobiological) mechanisms.
