Nesting instinct

Nesting behavior refers to an instinct in animals during reproduction to prepare a place with optimal conditions for offspring. The nesting place provides protection against predators and competitors that mean to exploit or kill offspring. It also provides protection against the physical environment.

Nest building is important in family structure and is therefore influenced by different mating behaviours and social settings. It is found in a variety of animals such as birds, fish, mammals, amphibians, and reptiles.
