Chipping sparrow song (AUDIO)

University of Massachusetts Amherst

Caption

Song by a chipping sparrow. Though it’s hard to perceive because chipping sparrows trill so fast, louder, lower notes are interspersed with softer, higher notes, denoting a negative relationship between amplitude and frequency as found for about one quarter of our species.
