Red-eyed Vireo: Anomalous Song

This unusual song was recorded in May, PA. I had no idea what it was until I tracked down the source. It turned out to be a Red-eyed Vireo. What is the cause of aberrant song? Perhaps an anatomical abnormality of the syrinx, or a hearing deficit, or something that adversely affected the learning process.
