Bird's nest in grass. Nesting behavior refers to an instinct in animals during reproduction to prepare a place with optimal conditions for offspring. [1] The nesting place provides protection against predators and competitors that mean to exploit or kill offspring. [2] It also provides protection against the physical environment. [1]

Nest building is habitual behaviour, [14] and nest-counts and faecal analysis at each nest site can be used to estimate hominid ape population counts and composition. [15] In the case of orangutans and chimpanzees, social influences are probably essential for the animals to develop successful nesting-behaviour.
Very precocial birds can be ready to leave the nest in a short period of time following hatching (e.g. 24 hours). Many precocial chicks are not independent in thermoregulation (the ability to regulate their body temperatures), and they depend on the attending parent(s) to brood them with body heat for a short time.
Like many ground-nesting birds, if an egg becomes displaced from the nest, the greylag rolls it back to the nest with its beak. [5] [11] [13] The sight of the displaced egg is the sign stimulus and elicits the egg-retrieval behavior. [5] First, the goose fixates its sight on the egg. [5] Next, it extends its neck over the egg. [5]
The females leave the nest after finishing laying to let the males incubate the eggs and take care of the young. [4] Male emus ( Dromaius novaehollandiae ) become broody after their mates start laying, and begin to incubate the eggs before the laying period is complete.
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements.The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus.
