More than 100 coots have moved into Danhe Wetland Park in Zezhou County, north China's Shanxi Province. They glide, dive and chase each other across the water, sending ripples everywhere. Known for their dark plumage and bright white frontal shields, they add a bit of chaos – and a lot of life – to the scene. Ongoing conservation work is improving the wetland. And the coots, it seems, have noticed.
