These Birds’ Backflips Are Fueled by Sugar

Researchers have found that a dietary shift to a high-sugar diet in ancient times enabled the manakin bird to develop its distinctive courtship display, which includes impressive backflips. This change in diet is believed to have provided the necessary energy for the bird's flashy and physically demanding mating rituals. The study suggests that the manakin's ability to exploit sugary food sources was a key factor in the evolution of its unique courtship behavior. As a result, the bird's high-energy displays are now a crucial part of its mating and breeding process.
