The whooping crane is an endangered crane species, native to North America, named for its “whooping” calls. Along with the sandhill crane, it is one of only two crane species native to North America, and it is also the tallest North American bird species. The whooping crane's lifespan is estimated to be 22-24 years in the wild. After being pushed to the brink of extinction, due to unregulated hunting and loss of habitat, and just 21 wild cranes remaining by 1941, conservation efforts would lead to a partial recovery. The total number of cranes in the surviving migratory population, plus three reintroduced flocks and in-captivity, only slightly exceeds 800 birds as of 2020.
