Researchers have identified a new owl species—improbably, more than 100 years after it was first discovered, reports Wired. The Rinjani scops owl, from the Indonesian island of Lombok, was thought to be a member of Otus magicus since 1896, when a British naturalist collected several specimens. But a visiting taxonomist who heard the Rinjani's call in 2003 realized it sounded totally different than the O. magicus. "It is a wake-up call for ornithologists: there is still much to learn," says a co-author of the study that identified the species.
Further investigation revealed subtle differences in color between the species, and a DNA sequencing confirmed the Rinjani scops owl was a different species—which has since been named Otus jolandae. “We’re realizing there’s a lot more diversity in plants and animals than we might have expected, just based on their physical appearance,” said one ornithologist.
