Birds exhibit nesting behavior by sitting on their eggs to keep them warm. This helps in maintaining a consistent temperature for the eggs, which prevents them from cooling too quickly.

When birds lay eggs they usually sit on them and keep them warm. Just like when a human is pregnant, our baby stays warm inside our body. If we freeze to death outside, our baby would die.
