Bruce the kea doesn’t just adapt — he rewrites the rules. 🤯 Missing his upper beak, he could be at a clear disadvantage. Instead, new research from UC, led by Dr Alex Grabham and Professor Ximena Nelson in collaboration with Professor Alex Taylor (INc-UAB) shows he has become the alpha male in his group. Rather than competing on the same terms as other birds, Bruce developed a completely new fighting strategy: jousting. By striking with his lower beak from different angles and with surprising force, he outperforms his peers and remains undefeated. High status gives Bruce priority access to food, lower stress levels than other birds in his group, and even grooming from those below him in the hierarchy. As Professor Ximena Nelson notes, Bruce’s story challenges what disability means for behaviourally complex species. But that isn’t the end of Bruce’s story. Thanks to a UC-led study published in Current Biology, Bruce has become an international star featured in media stories across the globe from the NY Times to National Geographic. A powerful example of how constraint can drive entirely new ways of succeeding. #Brucethekea #UCResarch UC Science | Universitat Autònoma de Barcelona | Willowbank Wildlife Reserve
