The Annobón scops owl (Otus feae) is a critically endangered owl endemic to the Equatorial Guinean island of Annobón. The current population is estimated to be around 50-249 individuals, with the population declining due to habitat alteration and destruction.[1] When describing the species in 1903, Tommaso Salvadori noted that the birds were abundant in wooded areas at altitudes of 400–500 metres on the island.[3] Few sightings of the bird have been reported since then.[4]

Little is known about the Annobón scops owl. It is morphologically similar to the African scops owl (Otus senegalensis), but is distinguished by a smaller wing length (about 120–135 mm),[5] shorter tarsi,[6] a longer tail,[6] and paler underwing barring.[6] The call of the Annobón scops owl is of a higher pitch than that of O. senegalensis with longer notes and more frequent oscillations.[6]

The Annobón scops owl is currently treated as a distinct species from the African scops owl, however genetic analysis performed in 2019 found little divergence between the two species.[7]
