MOORE HAVEN, Fla. — In Florida's Everglades, few species are more closely tied to the habitat's health than an endangered bird, the snail kite. The Everglade snail kite is a raptor, similar to a hawk, that eats just one thing: snails.
Over the last century, as much of the Everglades was drained, the bird's population declined precipitously. But the kite has bounced back recently thanks to an exotic snail. It's a rare case of an invasive species having a positive impact.
