The limpkin (Aramus guarauna), also called carrao, courlan, and crying bird, is a large wading bird related to rails and cranes, and the only extant species in the family Aramidae. It is found mostly in wetlands in warm parts of the Americas, from Florida to northern Argentina. It feeds on molluscs, with the diet dominated by apple snails of the genus Pomacea. Its name derives from its seeming limp when it walks. This bird is easier to hear than see. Its common vocalization is a loud wild wail or scream with some rattling quality, represented as 'kwEEEeeer or klAAAar.' This call is most often given at night and at dawn and dusk. Other calls include 'wooden clicking', clucks, and in alarm, a 'piercing bihk, bihk...'. (Source: Wikipedia.org, CC BY-SA)
