Much like human babies, juvenile songbirds babble before they master complex vocalizations of their adult tutors. We find that zebra finches use two distinct neural pathways for generating songs -- one for babbling early in life and one for singing in adulthood.

Photo below shows an adult zebra finch with two 4-week-old juveniles. Click on the buttons to hear the babbling and the mature singing.
