Nestling birds recognize their local song ‘dialect’

A recent study has shown that juvenile songbirds react to hearing the songs they will eventually produce as adults, even when they are as young as 12 days old. Experiments conducted on nestling pied flycatchers across Europe demonstrate that they preferentially respond to songs from their own species and, remarkably, their own population.A recent study has shown that juvenile songbirds react to hearing the songs they will eventually produce as adults, even when they are as young as 12 days old.
