Distribution and habitat
This owl's natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests where it is relatively widespread and the population is probably several hundred birds.
This species of owl is the only one on the island, except for the common barn owl. Its diet consists of insects, grasshoppers, beetles, moths, and small lizards. This type of owl is nocturnal (like most owls) and is not shy toward humans. It roosts close to tree trunks or within them. Females of the species are somewhat larger than males. The adult face and upper body are mostly brown, with white chin and eyebrows. It sometimes call during the day.
Conservation and status
The continued survival of the São Tomé scops owl depends upon stopping habitat loss in the remaining lowland rainforest of São Tomé, as does the survival of three other birds: the São Tomé ibis, São Tomé olive pigeon, and São Tomé oriole.
