 We've got two species of cranes in North America. Both of them pass through Kansas when they're migrating. We've got sandhill cranes, which are much more common, and then the endangered whooping crane. They're actually a species that was down to only about 20 individuals around the turn of the century. Lots of overharvest, habitat loss through the destructions of wetlands and those sorts of things. But through some captive breeding programs and other conservation measurements, they've recovered.
