Behavioral adaptations are actions or responses that help an organism survive. This means the way a creature acts—such as migrating, hibernating, forming mating rituals, or using camouflage to avoid predators—improves its chances of living long enough to reproduce. These are not permanent physical changes to the body, nor are they genetic changes passed down across generations in the sense of evolving anatomy. Also, while some behaviors are instinctual, others can be learned, and both can contribute to survival. So the core idea is that behavior, in its various forms, helps organisms cope with their environment.
