200 to 1,500 — Officially Not Endangered
The ae'o, or Hawaiian stilt, dwindled to roughly 200 birds in the 1940s. After more than 50 years of wetland restoration and predator control, its population has climbed past 1,500 — and the U.S. Fish and Wildlife Service just made it official, reclassifying the species from endangered to

In the 1940s, there were roughly two hundred of these birds left on Earth. Today there are more than fifteen hundred, and the U.S. government just made it official: this bird is no longer endangered.
Meet the ae'o, the Hawaiian stilt: a tall, black-and-white wading bird on impossibly long pink legs, found on nearly every main Hawaiian island. And its comeback took more than fifty years to earn.
The ae'o's decline wasn't caused by any one thing. Decades of overhunting, wetlands drained for farms and development, and predators that were never supposed to be in Hawaii, mongooses, cats, and rats, all chipped away at the population until, by the 1940s, only around two hundred birds remained. The federal government listed the ae'o as endangered in the early 1970s. On paper, that's the moment the story could have ended quietly, one more species slipping toward extinction, its name added to a long list nobody wants to grow.
Instead, researchers at the University of Hawaii spent the next five decades tracking it, literally. They analyzed more than two thousand nests across nine wetlands on Oahu, from 1963 all the way to 2020, working alongside the U.S. Fish and Wildlife Service, the state of Hawaii, private landowners, and local community groups who managed and restored the wetlands the ae'o depends on. Slowly, the data started showing something rare in conservation: nesting success going up, chick survival going up, year after year, not by accident, but because the work was actually working.
This July, the U.S. Fish and Wildlife Service made the recovery official, reclassifying the ae'o from endangered to threatened, a status change that took effect this past August. Alongside it came a new rule specifically designed to keep the momentum going, one that makes it easier for landowners and conservation groups to keep doing the habitat management and wetland restoration work that got the bird here in the first place. As one of the researchers behind the study put it, this isn't a story about a species that's finished recovering. It's a story about proof that the recovery is working, and that the community-and-conservationist partnership behind it is worth continuing.
That distinction matters. The ae'o isn't off every watch list. Sea level rise, habitat loss, and invasive predators are still real threats, and researchers are calling it a conservation success story still in progress, not a finished one. But going from two hundred birds to over fifteen hundred, using nothing but decades of unglamorous, patient wetland restoration, is exactly the kind of good news that doesn't happen by accident. It happens because people kept showing up for a bird most of the world has never heard of.
