Reunion Owl

Open encyclopedia reference

The Réunion scops owl (Otus grucheti) also known as the Réunion owl or Réunion lizard owl, is an extinct species of small owl that occurred on the Mascarene island of Réunion, but became extinct before any living birds were described; it is only known from subfossil bones. One of the three Mascarene owls, it was formerly classified in the genus Mascarenotus, and most likely was similar to a long-eared owl in size and appearance, but with nearly naked legs. However, according to recent studies, it and its relatives belong to the genus Otus, and is likely descended from the Otus sunia lineage. Compared to the Mauritius scops owl and the Rodrigues scops owl, it was the most terrestrial species of the genus, with long legs and possibly somewhat reduced flight capability; more probably though it was simply smaller than the Mauritius bird – between that species and the one from Rodrigues in size – but had equally long legs: the only suitable food available in quantity on Réunion were small birds.
