Master Hunter of the North: Crested Kingfisher

Synopsis
Much of the Chitose River in Hokkaido consists of spring water. This water rarely freezes, even in the middle of winter. Crested kingfishers make this river their permanent home. These kingfishers are about the size of pigeons. A high-speed camera was used to document how they hunt, capturing their dynamic underwater movements as they dive into the river to catch fish. The team also studied how the crested kingfishers raise their young on high cliffs between spring and summer. The juveniles that are lucky enough to survive, despite being targeted by predators, practice hunting using dead leaves and twigs before becoming expert hunters themselves.
