Detailed explanation-1: -Habituation is a simple learned behavior in which an animal gradually stops responding to a repeated stimulus. Imprinting is a specialized form of learning that occurs during a brief period in young animals-e.g., ducks imprinting on their mother.

Detailed explanation-2: -Many animals undergo habituation. For example, a microscopic freshwater organism, the hydra, contracts when disturbed by a slight touch. However, if it is disturbed repeatedly by such a stimulus, the hydra stops responding.

Detailed explanation-3: -Animals may respond to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather (stimulus) some animals will hibernate. Hibernation is a state of greatly reduced body activity, used to conserve food stored in the body.

Detailed explanation-4: -Birds can become stressed very quickly. Therefore, one of the first steps involves eliminating anything that might be causing either/or physical and emotional stress. Examples of things to try include: Provide the bird with a balanced and nutritional diet.
