What is a behavior that an animal does not need to learn?

A behavior that an animal does not need to learn is instinctive behavior, such as a sea turtle hatchling's instinct to move toward the ocean immediately after emerging from its eggs. This behavior is hardwired in their genetics and is essential for their survival, as it helps them escape predators and find their marine habitat. Other examples include a bird's instinct to build a nest or a salmon's instinct to return to its birthplace to spawn. These actions are performed without prior experience or learning.
