|Ninox scutulata japonica|
The Northern Boobook (Ninox japonica) is a species of bird in the true owl family. It was split from the Brown Hawk-Owl (Ninox scutulata). It is found in eastern Russia (Ussuriland), North Korea, South Korea, northern and central China, and Japan.
The Northern Boobook is currently split into a sedentary and migratory subspecies- N.j. totogo (described to be distributed in Taiwan and Ryukyu Islands with type locality in Lanyu) and N.j. japonica (which is described to be distributed throughout the rest of its range), respectively. However, new research suggests that a revision must be made, as it has been determined that there is low genetic differentiation between migratory and sedentary populations of this species.
