The northern white-faced owl (Ptilopsis leucotis) is a species of owl in the family Strigidae. 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, 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
This owl has a rather notable defense mechanism. When faced with a similar-sized predator (like another owl slightly larger than it), the bird flares its wings to appear larger. When faced with something much larger than itself (such as an eagle), 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,[3][4] and it shares the ability with relatives like the African scops owl.[5]
Many different types of owls have some ability to adopt a "concealing posture", also known by the German word Tarnstellung,[6] 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.[7] Such behavior has also been documented in Eastern screech owls in a natural setting reacting to threats.[8]
In popular culture
A member of this species named "Popo-chan" was the subject of a Japanese television show, during which the species' concealing posture was demonstrated.[9][10]
The Arknights character Ptilopsis is named and based on the Northern white-faced owl, with some of her art and animations referring to the species.

In the "Here are the highlights" section of the translated version there is a line translated as "famous in Japan in the mimicry Owl Giant African Scops of Popo Chan", and the "Giant African Scops" link takes readers to a page on Ptilopsis leucotis, the scientific name for the Northern White-faced Owl.
