In recent years islands and sandbars along the Wisconsin River have hosted ever-growing numbers of Greater Sandhill Cranes as they prepare to depart for their wintering areas. In Fall 2015, flocks that swelled to upwards of 10,000 birds converged on the stretch of the river above and below Aldo Leopold’s Shack. That’s a large proportion of the cranes that now nest in Wisconsin. Why has there been such an impressive resurgence in the crane population since Aldo Leopold worried about its impending extirpation 80 years ago, and what attracts all these birds to the vicinity of the Shack?

A lot of people worked hard to save habitat, so when the population would recover from over hunting there would be a place for this beautiful bird.
