A parrot with no upper beak has invented its own fighting style and has become the leader of the flock

It's about a kea named Bruce from New Zealand.

Details

Bruce is a kea, a rare New Zealand parrot that is completely missing the top part of its beak. He has previously caught the attention of scientists by using pebbles to groom himself.

Now researchers have discovered that Bruce has also invented his own fighting technique.

Instead of the usual techniques used by other kea, he uses sharp lunges with the lower part of the beak - something like "beak fencing". This method was so effective that other birds were unable to replicate it.

During the observations, the scientists recorded 227 conflict interactions in the group. Of the 36 confrontations in which Bruce participated, he won all of them.

The researchers also noticed that:

• his fighting technique immediately forced his opponents to retreat 73 per cent of the time
• he was the first to access the food
• he had the lowest stress hormone levels of any male
• other males even cleaned his feathers and beak

All of this confirmed Bruce's dominance in the group.

Why it matters

Bruce's story shows that animals can compensate for physical limitations through ingenuity and flexible behaviour.

Scientists believe this case is important for several reasons at once. It helps to better understand the intelligence and adaptability of kea and also raises the question of whether animals with disabilities always need human intervention.

Sometimes, as Bruce's example shows, the animal itself finds a way not just to survive, but to take a strong position in the group.

Background

Keas are considered some of the smartest parrots in the world. They are known for their curiosity, problem-solving skills and unconventional behaviour.

Bruce has already become a research hero as the first known kea to use a grooming tool.
