The song of male songbirds has the function of repelling rivals and attracting mates. Females often pay attention to certain features within a song, such as the “sexy syllables”, to assess the quality of the singing male. A team of researchers from the Max Planck Institute for Ornithology in Seewiesen and the University of Copenhagen, headed by Henrik Brumm, has now discovered that rock sparrows indicate their age and reproductive success with their songs and react to infidelity with a higher song volume. The scientists found that the tempo, pitch and amplitude of song reflect male reproductive success. Cuckolded males regardless of whether they were young or old, sang louder.
However, older males lost paternity more often in their own nest but could more than

When a male or female white-browed sparrow-weaver begins its song, its partner joins in at a certain time. They duet with each other by singing in turn and precisely in tune. A team led by researchers from the Max Planck Institute for Ornithology in Seewiesen used mobile transmitters to simultaneously record neural and acoustic signals from pairs of birds singing duets in their natural habitat. They found that the nerve cell activity in the brain of the singing bird changes and synchronizes with its partner when the partner begins to sing. The brains of both animals then essentially function as one, which leads to the perfect duet.
