The southern white-faced owl (''P. granti'') was formerly included in this species and the two were known as the white-faced scops-owl. It is found in a band across Africa between the Sahara and the Equator. It occurs in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ivory Coast, Djibouti, Eritrea, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Somalia, Sudan, Togo and Uganda. == Fight-or-flight response == The owl has a rather notable defense mechanism. When faced with another owl slightly larger than it, the bird flares its wings to appear larger. When faced with something much larger than itself, it pulls its feathers inwards, elongates its body, and narrows its eyes to thin slits. It is thought that it uses this ability to camouflage itself,〔Discussed in the "Habits" section of Northern White-faced Owl's entry in ''Owls of the World'' by Claus König and Friedhelm Weick (2008).

Johnsgard (1988), (p. 63 )〕 in which they squeeze and thin their body to look like a broken tree branch, and some types may also narrow their eyes to slits and fold a wing sideways across their chest in a Dracula-like manner to hide the lighter-colored feathers on their underparts.〔''Owls'' by Cynthia Berger (2005), (p. 42-43 ).〕 Such behavior has also been documented in eastern screech owls in a natural setting reacting to threats 〔See YouTube video (Wild Transformer Owls - New and Natural! ) for same behavior exhibited by eastern screech owls〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Northern white-faced owl」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
