Singing Zebra Finch Much like human babies, juvenile songbirds babble before they master complex vocalizations of their adult tutors. The Fee lab found that zebra finches use two distinct neural pathways for generating songs -- one for babbling early in life and one for singing in adulthood. This photo shows an adult zebra finch with two 4-week-old juveniles. To hear the babbling and the mature singing, go to this website and click on the buttons: http://web.mit.edu/~aronov/www/babbling/
