Habitat

The Seychelles scops-owl inhabits forests of native and introduced tree species, on upper slopes and in valleys, often shrouded in mist and usually close to a water source. It may once have occurred to sea level, and is still sometimes reported from lowland regions with suitable habitat, but generally occurs above 200 meters

Reproduction

Nests are found within wooded areas, which are made up mainly of exotic vegetation. Eight nests have been found by scientists, all in the cavities of two relatively uncommon tree species. Nests are usually found in live trees located amongst dense vegetation. A single egg is laid; congeners normally lay two, but Seychelles land birds characteristically lay a single egg. Observations at two nests revealed that incubation lasted for 3-4 weeks and the fledging period was 4-6 weeks. The species can probably breed year-round with peaks in nesting around May and October. Pairs can initiate re-nesting soon after nest failure. Breeding success is recorded as low at c.0.5 fledglings/territory/year, although this may be high enough to maintain population stability.

Feeding habits

They prey on lizards, insects, and possibly tree-frogs, which are common in their habitat. They also consume some vegetation. It forages on foliage and tree trunks, not just on the ground.

Conservation

This species is listed as Endangered because it has an extremely small population, which is probably stable. Its population size and very small range on one island make it susceptible to stochastic events, such as extreme weather events and the introduction of alien taxa.
