When male superb lyrebirds sing, they often move their bodies to the music in a choreographed way, say researchers who report their findings in the Cell Press journal Current Biology on June 6. The findings add to 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," said Anastasia Dalziell of Australian National University. "Just as we 'waltz' to waltz music but 'salsa' to salsa music, so lyrebirds step sideways with their tail spread out like a veil to one song -- which sounds like a 1980s video-arcade game -- while they jump and flap their wings with their tail in a mohawk position while singing a quiet 'plinkety-plinkety-plinkety.'"
The lyrebirds' dance movements are a voluntary embellishment to their singing; in other words, they can and do sing without dancing. Sometimes they also make mistakes in their dancing, an observation that suggests to Dalziell and her colleagues that dancing is challenging for the birds, just as it is for us humans (some more than others).
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.
"Sometimes after what seems to me to be a perfectly wonderful display by a male, I watch a female leave and check out his neighbor," Dalziell said.
