Natal homing, or natal philopatry, is the homing process by which some adult animals that have migrated away from their juvenile habitats return to their birthplace to reproduce. This process is primarily used by aquatic animals such as sea turtles and salmon, although some migratory birds and mammals also practice similar reproductive behaviors.
Natal homing is found in all species of sea turtles and in other animals such as salmon. How these turtles are able to return to their birthplace is an interesting phenomenon. Many researchers believe that sea turtles use a process called imprinting, which is a special type of learning that occurs when turtles first hatch that allows them to ...
Natal homing behavior is well described in sea turtles, and genetic testing of turtle populations at different nesting sites has shown that magnetic field is a more reliable indicator of genetic similarity than physical distance between sites. [70]
The homing characteristics of the ridley sea turtles make them more prone to mass casualty. The voyage to the natal nesting beaches is the dooming factor for them. Since Gahirmatha coast serves as the natal nesting beach for millions of turtles, it has immense importance on turtle conservation.
The 'Homing' characteristics of the ridley sea turtles make them more prone to mass casualty. The voyage to the natal nesting beaches is the dooming factor for the sea turtles. Since Gahirmatha coast serves as the natal nesting beach for millions of turtles, it has immense importance on turtle conservation. [2]
Sea turtle migration is the long-distance movements of sea turtles (superfamily Chelonioidea) notably the long-distance movement of adults to their breeding beaches, but also the offshore migration of hatchings. Sea turtle hatchings emerge from underground nests and crawl across the beach towards the sea. They then maintain an offshore heading ...
Homing (biology) A homing pigeon. These have been selectively bred to home over long distances. Homing is the inherent ability of an animal to navigate towards an original location through unfamiliar areas. This location may be a home territory or a breeding spot.
This "natal homing" has appeared remarkable to biologists, though there is now plentiful evidence for it, including from genetics. [82] How sea turtles navigate to their breeding beaches remains unknown.
