Limpkins (Aramus guarauna) are more commonly heard than seen. Most often heard at dawn, dusk, and during the night, limpkins typically vocalize with a loud and rattling wail or scream. However, in places where they do not fear people, such as in parks and wildlife refuges, limpkins may be active during the day, although they don't typically stray far from cover.
The limpkin is the only member of its taxonomic family, Aramidae. Although they resemble herons and ibises in general form, limpkins are generally considered to be more closely related to rails and cranes. Brown with white spots and streaks, limpkins have long necks, bills, and legs. Immature limpkins are similar in appearance to adults but have fewer white markings.
