Vocal learning occurs when young animals develop vocalizations by listening to sounds produced by adults. Vocal learning is a rare behavior, known in only eight groups of animals, including humans and songbirds. In this video, Dan Mennill summarizes the findings of a 6-year playback experiment that used loudspeakers to simulate vocal tutors in a free-living population of Savannah Sparrows (Passerculus sandwichensis). Together with his coauthors, Dan Mennill provides the first direct experimental evidence that wild birds learn to sing based on sounds heard early in life, that wild birds pass these songs on to subsequent generations, and that wild birds preferentially learn songs heard during two critical stages of development.
