DescriptionThe Anjouan scops owl occurs in grey and rufous colour phases and has very small ear tufts compared to other scops owls. The grey form is sooty grey with fine buff bars on the head and neck, a dark brown face with fine streaks and brown underparts with very fine brown streaks and vermiculations. The tail and flight feathers are sooty grey. The rufous form is browner and the marking contrast more with the plumage. Body length is {{convert|15|cm|in|abbr=on}} and the wingspan is {{convert|45|cm|in|abbr=on}}.[1] VoiceThe call of the Anjouan scops owl is a distinctive drawn-out whistle, which is repeated often with by short interludes,[2] which has been likened to the "pee-oo" call of the grey plover. Distribution and habitatThe Anjouan scops owl is found only on the island of Anjouan, Ndzuani in the local language, where it occurs in the remaining fragments of native upland forest, degraded forest and plantations. It appears to be dependent on large trees situated on steep slopes with cavities for nesting and roosting.[3] HabitsLittle known but probably nests and roosts in tree cavities and feeds mainly on insects.[1] Conservation and statusThis species was rediscovered in June 1992, after an absence of records dating back to 1886. It has an estimated population of less than 400. It is classified as "Critically Endangered" because its range is restricted to such a small area, which is being rapidly deforested. However, later analyses have since downlisted it to Endangered.[3] Bristol Conservation and The Science Foundation have currently conducted surveys on the island to determine how many owls remain.[4] References1. ^1 {{cite book | last1 = Kemp | first1 = Alan | last2 = Kemp | first2 = Meg | year = 1998 | title = SASOL Birds of Prey of Africa and its Islands | pages = 322–323 | publisher = New Holland | isbn = 1 85974 100 2}} 2. ^{{cite web | url = http://www.birdlife.org/datazone/speciesfactsheet.php?id=2183 | title = Anjouan Scops-owl Otus capnodes | accessdate = 30 October 2016 | publisher = Birdlife International}} 3. ^1 2 {{cite journal | author = BirdLife International | year = 2017 | title = Otus capnodes | journal = The IUCN Red List of Threatened Species | volume = 2017 | page = e.T22688686A119090936| doi = 10.2305/IUCN.UK.2017-3.RLTS.T22688686A119090936.en }} 4. ^{{cite web|url=http://news.mongabay.com/2009/1203-hance_anjouanscopsowl.html |title=Forgotten Species: the haunting whistle of the Anjouan scops-owl |work=Jeremy Hance |publisher=Mongabay.com |accessdate=2010-02-14 |archiveurl=https://web.archive.org/web/20100127092059/http://news.mongabay.com/2009/1203-hance_anjouanscopsowl.html |archivedate=27 January 2010 |deadurl=no }} External links
