MOORE HAVEN, Fla. — In Florida’s Everglades, few species are extra carefully tied to the habitat’s well being than an endangered chook, the snail kite. The Everglade snail kite is a raptor, just like a hawk, that eats only one factor: snails.
Over the past century, as a lot of the Everglades was drained, the chook’s inhabitants declined precipitously. However the kite has bounced again not too long ago due to an unique snail. It is a uncommon case of an invasive species having a optimistic impression.
Robert Fletcher, a College of Florida professor who directs a snail kite monitoring program, says the invasive species was first noticed in 2004. Inside just a few years, it had expanded by a lot of the Everglades. “And it was round that point,” he says, “that we began to see snail kite quantity improve.”

Few folks pay nearer consideration to the snail kite than Tyler Beck. He manages Florida’s the endangered chook’s inhabitants for Florida’s Fish and Wildlife Conservation Fee. On the western fringe of Lake Okeechobee, Tyler Beck makes use of an airboat to motor by marshes searching for kites. He sees one hovering over a clump of timber and cuts the boat’s engine. “Hear that decision?” he asks. “That is solely once they’re irritated.”
Overhead, the alarmed kite makes a fast clicking name because it hovers and swoops over the airboat. College of Florida researcher Brian Jeffrey wades by thigh-deep water towards the world he thinks the nest may be. Jeffrey directs a area group that screens Florida’s snail kite inhabitants. He finds the nest, however it’s 20 toes up, too excessive to depend the eggs or see if any have hatched. Different members of his group shall be again quickly with a ladder to verify on the nest.

Jeffrey has three area groups that cowl hundreds of sq. miles counting and monitoring Florida’s snail kites. The kites—and the sphere teams–range from Everglades Nationwide Park on the southern tip of Florida all the way in which as much as Paynes Prairie Protect State Park, close to Gainesville. He says, “We’ve lots of floor to cowl.”
Snail kites aren’t flashy. Males are a slate grey, females a splotchy brown. They get their title from their potential to seemingly float within the air. They had been one of many final chook species found within the U.S. due to the place they dwell, typically hidden within the Everglades.
Beck says the species is uniquely tailored to subsist virtually fully on a useful resource normally ample within the freshwater marshes: apple snails. “They’ve these actually lengthy talons that hook across the shell and get a superb grip on it to elevate it out of the water and carry it away,” he says. And, they’ve a protracted, hooked invoice they use to pry the snails from their shells.

Over the previous century, as a lot of their habitat was drained and water stopped flowing by elements of the Everglades, the snail kite inhabitants plummeted. It was one of many first birds placed on the endangered species listing within the 1960’s. Droughts contributed to the snail kite’s decline and by 2007, there have been fewer than 800 remaining. “Proper shortly after that although, this invasive snail got here in, and simply began flourishing, entering into each wetland, having these large inhabitants booms,” Beck says. “Since then, the snail kite inhabitants has been slowly rebounding.”
By final yr’s depend, there at the moment are greater than 3,000 snail kites. And, though it is early within the season, area groups are discovering a number of nests with eggs and chicks.
Beck eases the airboat up subsequent to a willow tree the place he is noticed a nest. Standing within the boat, this one is at eye stage. He says, “We have got two little nestling snail kites. These are most likely about ten days outdated. The mother and father, you may hear them over us, they’re upset that we’re at their nest.” Beck and Jeffrey mark the placement, water ranges, peak of the nest after which motor away. The mother and father quickly return, carrying snails.

Nobody’s certain about how the unique snails had been launched into the Everglades. They’re associated to Florida’s apple snails and are generally utilized in house aquariums. The invader, the Island apple snail, is present in comparable habitat in South America and is bigger than its Florida cousin. It lays eggs within the hundreds in pink clusters seen on the stalks of lots of the marsh crops.
Efforts to revive Florida’s Everglades have helped the snail kite, bringing again native vegetation and restoring the move of water to once-parched marshes. It has been within the works for greater than 30 years with a value of greater than $20 billion. However progress is incremental and onerous to measure. Within the meantime, scientists say the invasive snail might have saved the snail kite.
However College of Florida scientist Robert Fletcher is anxious in regards to the potential impression the species can have on the Everglades over the long-term. He says, “What we ought to be enthusiastic about is how can we restore native snails to get these advantages moderately than counting on this non-native species that may have detrimental impacts on the ecosystem.”
The South American snails might already be taking a toll on some native marsh crops, an indication hassle could also be looming. Within the meantime, they’ve helped pull Florida’s endangered snail kite again from the specter of extinction.
