One threat to parrot arises from their attractiveness as "talking" companions to humans, leading to a high demand for trade that involves hundreds of thousands of birds annually on a global basis, and gives parrots a high monetary value. There is an urgent need to change the attitudes of both the many millions who keep parrots, and those who make billions of dollars in trading them. Neither group accepts responsibility for survival of parrots in the wild, and governments find it difficult to establish sustainable use regimes.
