Birds of Europe - Bustards, Cranes and Rails

Name all species of waterfowl that have been recorded in Europe, including escapees and vagrants. As a hint, taxonomic groups (not necessarily families) are given. In some cases, the name is displayed. I arbitrarily split the rails into two groups based only on size and not taxonomic realtions. (I) = invasive, escapee (A) = vagrant (E) = european endemic
