Ecology and Conservation of Blakiston’s Fish Owl in Japan

Chapter
Part of the Ecological Research Monographs book series (ECOLOGICAL)

Abstract

The island subspecies of Blakiston’s fish owl, Bubo blakistoni blakistoni, was once close to extinction (from the late 1980s to the middle 1990s) due to habitat destruction. However, after the threat to the population was recognized, the status of the species in Japan was designated critically endangered (CR), and aggressive conservation efforts were implemented. As a result, the population, fortunately, began to recover, starting in the mid-2000s, but because of the highly protected status of this species, information about its ecology in Japan has rarely been released to the public. Here, a summary of ongoing field research into the ecology and habitat requirements of Blakiston’s fish owl, such as nest characteristics, breeding ecology, diet, home range, and the density of fish in the habitat, as well its conservation is presented.
