All wild birds of the same species sing the same song. How do the birds learn their species song?

Wild birds of the same species learn their songs primarily through a combination of innate behavior and social learning. Young birds listen to adult males singing and memorize the sounds during a critical learning period, often referred to as the "sensitive phase." They then practice and refine their songs through vocal imitation, gradually developing the species-specific song. Environmental factors and interactions with other birds also play a role in shaping their song, ensuring that it remains consistent within the species.
