The Limpkin’s favorite food is the Florida Apple Snail. These snails are quite large and, of course, have slippery shells. One of my books mentions that the Limpkin’s bill has a slight gap between the mandibles, near the tip of the bill. It’s just enough of a curve to help them grip the snails. You can see the gap in this photo, taken at Three Lakes WMA, also near Kissimmee.
