Scientists experimentаlly mаnipulаted tail length in male African widоwbirds, a species in which males nоrmally have tails lоnger than their bodies. Using scissors and glue, the scientists gave some males tails longer than normal; others were given shorter-than-normal tails. Controls were left with normal-length tails. Later, males with artificially elongated tails attracted many more mates than those with normal or shortened tails. These experimental results best support that widowbirds experience
