The Bare throated tiger heron (Tigrisoma mexicanum) is found in more open habitats such as lake banks and river from Mexico to north-western Colombia. It has yellow-green facial skin and orange iris, and differs from other species of the genus by its bare yellow throat. The bare throat of this species was recognized for years as being highly distinctive. It is now placed in the same genus as the other two South American tiger herons - the Rufescent Tiger Heron and Fasciated Tiger Heron. The Bare-throated Tiger Heron is a bird of tropical swamps. Along the coast, it is typically a mangrove species. It is found, however, in a variety of coastal and freshwater situations, typically characterized as forest edged aquatic habitats. It feeds in coastal lagoons, mangrove swamps, fresh water marshes, swamps, gallery forests along rivers and streams, and wet meadows.
