Grus americana
Whooping cranes are snow-white, five-foot-tall birds that were reduced to 21 wild individuals in 1941 after wetland drainage and hunting. Decades of protection, captive breeding, and daring ultralight-led migrations have rebuilt a wild population of a few hundred, still fragile. Their trumpeting calls carry over a kilometre, and pairs dance and duet to strengthen lifelong bonds. Habitat protection along the Gulf coast remains essential.
