A recently born whooping crane chick, a critically endangered species, walks in an enclosure at the Audubon Nature Institute's Species Survival Center in New Orleans, Thursday, June 21, 2018. Their numbers dwindled to 21 in the 1940s, including a handful in Louisiana. That’s grown to 670 today – about 510 in the wild, the rest in captivity. (Photo by Gerald Herbert/AP Photo)
