Overview
- University of Canterbury scientists studied Bruce at Willowbank Wildlife Reserve and published the results in Current Biology.
- The team logged 227 social interactions in the group and recorded 36 male fights involving Bruce, who won every bout.
- Lacking an upper beak, he drives his lower beak forward in quick thrusts that often stop opponents on the spot.
- Rivals retreated in 73% of encounters, and his dominance brought first access to food, grooming from other males, and the lowest stress markers.
- The authors say this single case shows behavioral innovation can offset disability and could inform decisions on prosthetics for injured wildlife.
