A new study from McMaster University challenged Charles Darwin's long-standing theory of female choice. Rather than females being drawn to males that have the most vibrant tail feathers or best dance moves, researchers suggest that, once aroused, courtship displays have no bearing on a female's mate preference.
Blue-capped cordonbleu songbirds appear to use a lightning speed tap dance and ribbon baton-like performances to accompany their songs during routine courtship displays.
For nightingales, nothing is hotter than good fathering skills. That's at least what bird experts now think after extensively studying the songs of male nightingales. Traditionally, it was thought that these songs simply told listening females about a male's health and other desirable traits. Now, they think the 'lyrics' are actually about how good a dad he'd be.
Male birds in poor physical condition may cheat unknown females and give a false impression by faking their song, suggests a new study.
