Something like 12 of the 15 species of cranes around the world are endangered. Sandhill cranes are not endangered: there are perhaps half a million of them. They have recovered from low population numbers and are only endangered in some areas. They did go through quite a narrow evolutionary bottleneck, reducing their genetic variability and their future viability. But according to governments, it is OK to hunt them. But they are big, slow fliers. Shooting them is like shooting fish in a barrel.
