Thai National Parks

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.

Subspecies

The northern boobook is currently split into a sedentary and migratory subspecies: N.j. totogo (distributed in Taiwan and Ryukyu Islands with type locality in Lanyu) and N.j. japonica (which is 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.
