The ability of certain
animals to
navigate by
instinct to specific sites, apparently without using any
landmarks. Examples are
salmon returning to the same
rivers where they were born,
birds returning to the same
nesting sites after annual
migrations, or
Florida green tortoises finding the same beaches upon which to lay their
eggs.
