California Condors used to range from California to Florida and from Canada all the way down to Mexico. But last century, their population crashed. The federal government listed them as endangered in 1967, and in 1982, only 23 condors survived worldwide. Now, there are more than 600 alive, but they aren't doing as well as scientists expect it. New research explains the mystery of why, despite many protections, the birds are still struggling.
