The Réunion scops owl 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.
Region
Southwest Indian Ocean
Typical Environment
Endemic to Réunion Island, where it likely occupied native forests and wooded ravines from lowlands into the uplands. It probably hunted along forest edges and in semi-open habitats where reptiles and large insects were abundant. Daytime roosts were likely in dense foliage or tree cavities, as in many scops owls. The species disappeared before detailed ecological notes could be recorded, so its precise habitat preferences remain inferred.

The Réunion scops owl, also called the Réunion lizard owl, was an island endemic known only from subfossil remains and historical accounts. It likely preyed heavily on lizards and large insects and had unusually bare legs compared with many scops owls. Formerly placed in the genus Mascarenotus, it is now regarded as part of Otus, probably derived from the Otus sunia lineage. It vanished after human settlement of Réunion, likely due to habitat loss and introduced predators.
Temperament
solitary and territorial
Flight Pattern
silent, buoyant flight with short bursts between perches
Social Behavior
Like other scops owls, it was probably solitary outside the breeding season and formed pairs to nest. Nests were likely placed in tree cavities or sheltered crevices. Parental care would have been shared, with adults provisioning young at night.
Migratory Pattern
Resident
Song Description
Presumed to have given simple, repeated hoots or whistles typical of Otus species. Vocalizations were likely low-pitched and spaced, used for territory advertisement and mate contact at night.
