The bird that was already extinct
For most of the twentieth century, Japan believed the tancho was gone: hunted out, its wetlands drained. Then a handful were found alive in the one place too boggy to farm: the Kushiro marsh. In the killing winter of 1952, villagers began scattering corn. The cranes stayed. The village eventually renamed itself Tsurui ("where the cranes live"), and the population climbed from dozens to well over a thousand.
That's the history. What you fly here for is the dance: two red-crowned cranes facing each other in falling snow, wings wide, heads thrown back, in a courtship display that hasn't changed since the Pleistocene. Photographers count Tsurui among the great wildlife sites on Earth.
