Job description: In many bird species, young males learn their songs from their fathers. But, learning occurs with error, so songs can change over generations. This culturally transmitted behaviour fascinates the public and has important implications for conservation. Birds use songs to choose mates. If songs diverge among partly isolated populations, this may prevent those populations from exchanging genes and threaten species viability. Data-driven mechanistic models of the evolution of birdsong could help us understand birdsong evolution, but few such models exist. Birdsong evolution is in some ways analogous to genome evolution. Notes are like nucleotides, and mutations(i.e., errors in copying) can change one note to another. Notes or song segments can be inserte
