Along the Chitose River in Hokkaido, Japan, lives a bird that the world knows little about. The kingfisher, a small, mysterious bird, is a high-precision hunter that plucks tiny fish out of the river at breakneck speeds. Photographing them requires great equipment, great patience, and often, great luck. Wildlife photographer Tadashi Shimada observes three species of kingfishers over the course of a year, tracking their hunting, courting and rearing skills. He takes us underwater and into their cave-like nests to show these flying jewels as they've never been seen before.
Below-zero temperatures and a shortage of fish won't stop the kingfishers from hunting in the freezing river.
