Male white-crowned sparrows have distinctive songs that identify not only their species but also the general region in which they live. In the wild, male birds first begin singing a soft "sub-song" at 150 to 200 days after hatching; over time, this develops into the full song characteristic of the species and region in which they live. Experiments with lab-reared birds reveal that males can only learn the song of white-crowned sparrows
