Hand-rolled, kettle-boiled, baked to perfection. Worth every minute at the bakery.
Summary
A study on Bruce, a kea parrot missing his entire upper beak, who became the alpha male of his group through an innovative lower-beak jousting technique. Despite being the only disabled bird in his captive circus group, Bruce remained undefeated in dominance interactions. The research demonstrates how behavioral innovation can help overcome physical disability, expanding understanding of behavioral flexibility and resilience in large-brained species.
