By Keeping the Beat, Sea Lion Sheds New Light on Animals' Movements to Sound




Researchers document sea lion’s synchronized head bobbing to ‘Boogie Wonderland’

Move over dancing bears, Ronan the sea lion really does know how to boogie to the beat.

A California sea lion who bobs her head in time with music has given scientists the first empirical evidence of an animal that is not capable of vocal mimicry but can keep the beat, according to new research published by the American Psychological Association.

The study’s authors suggest that their findings challenge current scientific theories that an animal’s ability to synchronize its movements with sound are associated with the same brain mechanisms that allow for vocal mimicry in humans and some birds such as cockatoos, parrots and budgerigars. The findings were published online April 1 in APA’s Journal of Comparative Psychology®.
