Zurich, Switzerland (LiveScience): This article may explain a lot of human relations: male songbirds often compete for mates through singing contests. The dominant ones usually start singing before an opponent finishes his song, signaling aggression that female birds sometimes find attractive. In a study of nightingales, scientists were interested to learn why 49 percent of the males didn't have a mate during breeding season. "One possibility is that they select their future mate on the basis of the performance during a vocal interaction, because nightingales interact for hours during the night," said Hansjoerg Kunc, a researcher with University of Zurich, Switzerland.
