Both scientists and average Joes have long known about (and enjoyed) the beautiful songs produced by dozens of species of male songbirds across the globe. New research, however, shows that a few songbirds can both sing and dance as they can do a little jig so fast it can’t be followed by the human eye. Even more surprisingly, in at least one species, both males and females put on a complex song and dance mating routine.
It has been known for some time that both male and female cordon-bleu birds bob up and down when they sing to their mates. New research using using high-speed video cameras has now spotted a remarkable quick-step dance that the birds perform mid-hop during their courting display.
It's no secret that this year has been a volatile one for the markets. The S&P 500 is down 18% year to date, while the Nasdaq Composite is off by 27% year to date. Meanwhile, the VIX, a key measure of volatility, is up 49% year to date at 24.72. However, it has spiked as Read More
The study by a team of ornithologists from Japan and Germany was published this week in the open access journal Nature Scientific Reports.
Because each bird’s dance became more vigorous if its mate was on the same perch, the team thinks the vibrations might be adding a tactile element to the courtship ritual.
Statements from researchers
“It’s a really rare phenomenon that songbirds produce non-vocal sounds,” explained senior author Masayo Soma of Hokkaido University in Japan. “Some species produce non-vocal sounds with their wings, but they usually don’t use their feet.”
“It wasn’t very easy to record the behaviours because these birds are very choosy, and they only perform courtship displays to the individuals they like,” Dr Soma noted in a recent interview
“It is very astonishing,” commented Manfred Gahr, co-author of the study, from the Max Planck Institute for Ornithology close to Munich. “Maybe more birds are doing it, but it just has not been seen.”
