Male Java sparrows may coordinate their bill-clicking sounds with the notes of their song. Birds may communicate using both vocalizations and movement, as for instance occurs during courtship displays, but scientists’ understanding of how they coordinate their movements with the sounds they produce is limited. To further investigate birds’ communicative and musical abilities, the authors of this study looked into the vocalizations and bill sounds associated with singing in the Java sparrow, a song bird.
