Male superb lyrebirds often move their bodies to the music in a choreographed way as they sing, adding evidence from human cultures around the world that music and dance are deeply intertwined activities.
"Like humans, male superb lyrebirds have different dance movements to go with different songs," Anastasia Dalziell of Australian National University, said.

The lyrebirds' dance movements are a voluntary embellishment to their singing; in other words, they can and do sing without dancing.
As much as people love to dance, the activity is even more crucial for the birds.
Before they can mate, males must impress females with their dancing skills.
They put a lot of work into their dances, with years of practice before they reach maturity.
In the breeding season, female lyrebirds will visit several different males to watch their song-and-dance routines. Exactly what those females are looking for is still anyone's guess.
The findings are published in the Cell Press journal Current Biology.
