大科摩羅角鴞

<em>Otus pauliani</em>, the Comoro scops owl, is a critically small nocturnal raptor in the family Strigidae, endemic to Mount Karthala on Grande Comore island in the Comoros archipelago. This species is one of the world's most geographically restricted owls, confined to a single volcano's upper montane forests above approximately 1,000 metres elevation. It belongs to the diverse Otus scops owl complex widespread across Africa and Asia, with island forms often evolving in isolation. The Comoro scops owl inhabits dense montane forest and heath zones dominated by native tree species. Its cryptic plumage provides excellent camouflage among bark and foliage. The IUCN lists it as Endangered due to its extremely small range, estimated tiny population, and ongoing loss of montane forest habitat from agricultural encroachment and periodic eruptions from Karthala. Like other scops owls, it is presumed to be insectivorous, hunting invertebrates nocturnally, though specific dietary data remain limited. Biological traits including body mass, lifespan, and detailed morphometrics remain poorly documented for this species. Conservation is particularly challenging given the species' restriction to a single active volcanic mountain, making the entire population vulnerable to a single catastrophic event. Protecting the remaining montane forest belt on Grande Comore is the primary conservation priority for this owl.
