Blue-capped cordon bleu finches tap dance so fast it can’t be seen by the naked eye.
When it comes to wooing each other, blue-capped cordon bleu finches (Uraeginthus cyanocephalus) sing and head bob, but they also dance ŠSomething we didn? know about because we couldn? see it.
“You cannot see this with the naked eye because it? so rapid,?study co-author Masayo Soma of Hokkaido University in Japan told National Geographic.
“During the display, both birds would dance about three steps in less time than it takes us to blink,?writes Nat Geo.
The study is called “Tap dancing birds: the multimodal mutual courtship display of males and females in a socially monogamous songbird.?It was published in Nature.
No other birds seem to do this tap dancing behavior either, according to the study. Most of the time, the female is very picky in who she chooses for a mate. It? different for blue-capped cordon bleus however; both males and females are choosy. This is because they are monogamous.
The researchers filmed the birds courting each other, which was when they discovered the birds?tap dancing. The finding was “novel,?according to the scientists, and “suggests that the evolution of multimodal courtship display as an intersexual communication should be considered.?lt;/span>
So why do both birds dance? Scientists aren? sure, but no doubt they?l try to figure out the significance.
Read the study? introduction below:
“Elaborate courtship displays are assumed to have evolved under strong sexual selection pressure in males Males of polygynous species (e.g., spiders, frogs, fishes, and birds) use multimodal courtship displays to increase the efficacy of signaling. Thus, by coordinating visual and acoustic displays without interference between display components, polygynous male birds can better convey sexual signals.
Much research has focused on male?emale directed courtship displays performed by polygynous male birds, while the occurrence of both male?emale and female?ale directed courtship displays performed by socially monogamous birds has often been overlooked. Elaborate mutual dance displays between sexes are known to be performed by socially monogamous non-passerine birds, which are non-vocal learners, such as grebes. In socially monogamous non-passerine birds, dance duets may serve similar functions as vocal duets do in songbirds: contributing to pair formation, pair bonding, or mate guarding. The evolution and mechanisms of dance duets have received far less attention than have vocal duets. Furthermore, why a few songbird species use both song and dance displays as intersexual communication is a puzzling question.?lt;/span>
