Rails and coots are mostly weak fliers but strong runners. Some of the island species have become completely flightless, and consequently have been decimated by introduced predators. Species in this bird family are usually aquatic, and inhabit all kinds of wetland areas usually in and around dense vegetation. Members of this family are found all over the globe, except in the driest deserts and on the ice caps. Moorhens, crakes and gallinules are also included in this family.
