Learned behavior in animals can occur through various forms of conditioning, as well as observation and reasoning. Animals are able to learn behaviors that help them adapt to their environments and ensure survival. Learning allows animals to be more flexible than if they relied solely on innate behaviors determined by their genetics. The types of learning include habituation, classical and operant conditioning, observation, food hoarding, imprinting, and insight learning. An animal can only learn behaviors that its physical form allows, as a dolphin cannot ride a bicycle due to its lack of legs and fingers.
