Researchers have documented the remarkable adaptive behaviors of Bruce, a kea parrot in New Zealand who lost the upper half of his beak. Despite this injury, Bruce has become the dominant male in his group by developing a unique fighting style called "beak jousting," which utilizes his lower beak to defeat rivals. This behavioral innovation not only secures his alpha status but also leads to benefits such as preferential feeding and grooming from other males, resulting in lower stress levels than typically observed in dominant animals.
