How Do Birds Learn How to Sing?

Birdsong is a fascinating blend of genetic predisposition and social learning, showcasing the diverse strategies birds employ to communicate. Some bird species inherit a predisposition to specific songs through their DNA, essentially being born with an innate template of what their song should sound like. This genetic blueprint ensures that their songs remain consistent across generations, even in isolation. For instance, certain sparrow species exhibit this innate learning, where their song remains remarkably similar regardless of their environment or exposure to other birds. Conversely, many bird species learn their songs through social interactions, acquiring their vocal repertoire by listening to and mimicking the songs of adult peers. However, despite studying birds for hundreds of years, we still have very little idea about how their language works and what (if anything) they are trying to communicate.
