Some birds have a remarkable talent for dancing, two studies published in Current Biology suggest.
Previously, it was thought that only humans had the ability to dance, but footage has revealed that some parrots have a near-perfect sense of rhythm.
This film of Snowball, a sulphur-crested cockatoo, shows him dancing to his favourite song - the Backstreet Boys' Everybody - played at three different tempos.
Frame-by-frame analysis revealed that he was able to keep time as the beat changed.
The findings could help to shed light on how our relationship with music and the capacity to dance came about.
