- Kea, a parrot species native to New Zealand, was observed moving traffic cones strategically near a tunnel to stop cars and obtain food from humans.
- Researchers measure bird intelligence through various tests like the mirror test for self-awareness, Aesop's Fable test for problem-solving, delayed gratification for self-control, vocal mimicry for communication, and spatial memory tasks.
- Bird brains, especially in parrots and songbirds, have high neuron density, enabling cognitive abilities rivaling primates despite smaller brain size.
- Corvids (e.g., crows, ravens) excel in tool use and planning, while parrots (e.g., African greys, kea) lead in communication and social cognition.
- The kakapo, another New Zealand parrot, is considered among the dumbest birds due to ineffective survival strategies, contrasting with the intelligence of kea.
