Content overview: “Caribbean Islands Were Once a Hotspot for Barn Owl Diversity, Fossil Study Reveals”. A new study published in the Proceedings of the National Academy of Sciences reveals that the Caribbean islands were once a center of diversity for barn owls, with at least five unique species inhabiting the region before human arrival. The research, led by Jessica Oswald, a paleontologist at the Florida Museum of Natural History, analyzed fossil remains from across the Bahamas, Cuba, Jamaica, and other islands, uncovering a rich evolutionary history that had been largely overlooked.
The findings show that these island owls were not just visitors but long-term residents that evolved distinct traits, including some species that were flightless or nearly so. The study matters because it highlights how island ecosystems can foster unique biodiversity, and how human activity—such as habitat destruction and the introduction of invasive species—likely contributed to the extinction of these birds.
