Java sparrows fall in love on the dance floor
Today’s Video of the Day comes from a new study from Hokkaido University that shows how java sparrows fall in love on the dance floor.
According to the research, java sparrows are more likely to mate after they have danced together. This contradicts previous theories that suggested that singing songs together was the main indicator of copulation.
Most songbirds sing duets before mating. But in java sparrows, only the male sings as a means of courtship before both the male and female dance together. The study found that the combination of the male singing and the collaborative dancing were linked to higher rates of mating success.
