Limpkin

Florida is the only state in the U.S. where Limpkins breed. They are thought to be closely related to cranes and can be found year-round throughout Florida except for the western panhandle. When they aren’t searching for apple snails and freshwater clams, Limpkins can often be found sitting on snags or skulking in reed beds close to the water’s edge. They are locally known as the "wailing bird" or "crying bird" due to their loud mournful call, usually issued at night by territorial males. The Limpkin is listed in Florida as a species of special concern due to habitat loss.
