This presentation provides a comprehensive overview of "behavioural patterns in animals", including their classification into "innate, learned, social, and rhythmic behaviours". It explains the characteristics, mechanisms, and biological significance of each behavioural type with classical examples from animal studies. The presentation also discusses the "internal and external factors influencing behaviour", highlights the "applications of animal behaviour" in ecology, conservation, wildlife management, and animal welfare, and includes important concepts of "classical conditioning", such as Pavlov's dog experiment and the Little Albert experiment. The content has been compiled from standard zoology and animal behaviour references, making it suitable for undergraduate and postgraduate students.
