Moorhens — sometimes called marsh hens — are medium-sized water birds that are members of the rail family, (Rallidae). Most species are placed in the genus Gallinula, Latin for "little hen". They are close relatives of coots, and because of their apparently nervous behaviour (frequently twitching tail, neck and grinding their backs) are sometimes called "skitty coots". They are often referred to as (black) gallinules.
Two species from the Australian region, sometimes separated in Tribonyx, are called "nativehens". The nativehens differ visually by shorter, thicker and stubbier toes and bills, and longer tails that lack the white signal pattern of typical moorhens.
