Millennia of Human Relocation Shaped Caribbean Parrot Diversity

A recent study on Caribbean parrots has revealed that these birds were once more prevalent and varied than previously thought, with species believed to be unique to specific islands. Over half of the Caribbean parrot species are now extinct, making them the most endangered bird group globally. The study sheds light on the historical distribution of parrots and the human role in their relocation. Genetic sequencing has helped identify fossil species and establish connections between extinct Caribbean birds and those in Africa and New Zealand. Understanding the past distribution of species is crucial for conservation efforts.
