Definition: Tendency of an individual to return to, or remain in, its birthplace to reproduce. It happens on both, aquatic and terrestrial animals.Edit
Also known as natal homing.Edit
This type of behavior is most commonly seen in a variety of bird and turtle species. This type of behavior is thought to be naturally selected because it takes more energy and fitness to create a new nesting site each year (Lee et al., 2007). Other advantages are cooperation with family members and avoidance of social barriers between non-member groups when migrating.
The disadvantages are the vulnerability to catastrophes and the reduction of gene flow. The genetic diversity is distributed among populations, rather than within these breeding colonies (Stiebens, et al. 2013).Studies show that females have a higher probability of returning to their nesting sight than males ( Greenwood and Harvey, 1982 & Lee et al., 2007).
