LAURA SULLIVAN, HOST:

It's been a tough few years in South Florida for wading birds like egrets, herons and ibises. All of them depend on the area's wetlands. The problem is the wetlands are shrinking and the last few years have been dry ones in Florida.

Despite that, the federal government says one wading bird, the wood stork, may be doing all right. It's doing well enough in other parts of the country, at least, that it soon may be removed from the endangered species list. NPR's Greg Allen has that story from Miami.

GREG ALLEN, BYLINE: In Southwest Florida, it's a bird-watcher's paradise, 13,000 acres of wetlands and old-growth cypress trees, the Corkscrew Swamp Sanctuary.

JASON LAURITSEN: It's a barred owl. Corkscrew actually is probably - it's the best place I know of in the country to view wild barred owls during the day.

ALLEN: Jason Lauritsen is standing on a boardwalk looking up at an imposing bird, a foot tall barred owl. Lauritsen is the director at the sanctuary named for the old Corkscrew River that begins in the swamps and marshes here. The National Audubon Society acquired the land to preserve the sanctuary in the 1950s, in part because of its importance as a rookery for wood storks. In 1913, renowned ornithologist Thomas Gilbert Pearson visited Corkscrew and, Lauritsen says, was awed by what he found.

LAURITSEN: Thomas Gilbert Pearson identified what he estimated to be 100,000 wood storks in the nesting colony right here. A hundred thousand.

ALLEN: Right here, yeah.

LAURITSEN: Right here. He wrote in his book that this was the most important wading bird colony in Florida.

ALLEN: When visitors see a wood stork, it grabs their attention. Over three feet high with bald heads and black-and-white plumage, their wingspans can reach over six feet. By the 1970s, though, because of habitat loss and drought, Florida's wood stork population fell to just a couple of thousand. The population has bounced back. But at Corkscrew, even today, wood storks are in short supply.

LAURITSEN: Well, right now, we're on a section of the boardwalk that we have the capacity to close off. When the wood storks nest over the boardwalk, this is one of their favorite spots.

ALLEN: Lauritsen says in the past, he's counted as many as 60 wood stork nests in a single cypress tree. It's been 14 years, though, since wood storks have nested in this spot. Lauritsen and others involved in wood stork conservation are concerned. While they've traditionally liked to nest here in Corkscrew, wood storks may fly 50 miles in a day, looking for shallow pools where they forage for food.

In this part of Southwest Florida, between fast-growing Naples and Fort Myers, many of the wetlands have been drained and filled, especially one habitat that's critical for wood storks: shallow areas called wet prairies.

LAURITSEN: We've actually lost 82 percent of our wet prairies within the core foraging area for Corkscrew's wood storks. So that's - really, that's what's behind their decline.

ALLEN: A recent survey shows that throughout South Florida, wading bird populations, including wood storks, have declined dramatically over the last 10 years. Last year, according to the survey, every single wood stork nest in the region, 820 in all, either failed or was abandoned. But as bleak as the picture is in South Florida, elsewhere in the state, and in Georgia and South Carolina, wood storks aren't doing badly.

CHUCK UNDERWOOD: Well, what we've seen is this particular species of bird has rebounded significantly.

ALLEN: Chuck Underwood is with the U.S. Fish and Wildlife Service in Florida. While South Florida historically has been the center of the wood stork's breeding population, development and dry conditions have forced the birds to feed and nest elsewhere.

UNDERWOOD: Over the past several years, the bird has expanded further north and is breeding in larger and larger numbers in colonies all the way up into the various southern, southeastern portion of North Carolina. So that is one of the reasons, we think, we're at a point where the species is no longer dependent upon that specific location in South Florida.

ALLEN: U.S. Fish and Wildlife recently announced they plan to upgrade the wood stork status, moving it from endangered to threatened. Practically speaking, the rule, if it becomes final, won't remove any protections from the wood stork.

But Alan DeSerio says it's a step toward eventually removing the bird from the endangered species list. DeSerio is an attorney with the Pacific Legal Foundation, a property rights advocacy group that petitioned the government to make the change.

ALAN DESERIO: We're happy, and I would assume most environmental groups would be very happy with the progress that the wood stork has made. It's really just no longer entitled to that designation of endangered.

ALLEN: Audubon and other conservation groups are happy that the wood stork population has increased in recent years. But Audubon officials believe wood storks should stay on the endangered list. They say until Florida improves its protection of wetlands and finishes restoring the Everglades, the long-term survival of the wood stork is still very much up in the air.
