Scientists have discovered the species of songbird performs a tap dance so fast that it can’ t be seen by the naked eyes. Researchers from Japan and Germany slow down footages of the blue capped cordon-bleu songbirds during courtship. Scientists have discovered that tap dance is in the courtship performance of both male and female cordon-bleus. The next step for the researchers is to try and pick whether the birds mate is moved by the sight, the sound or the vibrations of this fancy foot work.   Such is the agility of the songbirds show stopping quickstep that could only be fully appreciated in super slow-motion.
