Behavioral adaptation refers to a behavior that an animal has developed or changed over time in order to increase its chances of survival. Unlike structural adaptations, which are physical features of an organism, behavioral adaptations are the things organisms do to survive. Examples of behavioral adaptations include migration, hibernation, learned behavior, alteration in the mode of reproduction, altered feeding habits, and distinct modes of communication. Behavioral adaptations are mostly learned, not inherited, and organisms adapt and change to make their lives more comfortable, especially when faced with new circumstances and surroundings.
