Swainson, 1827

The genus was erected by the English naturalist William Swainson in 1827 with the rufescent tiger heron (Tigrisoma lineatum) as the type species.[1][2] The genus name combines the Ancient Greek tigris, meaning "tiger" and somā, meaning "body".[3]


Three species are placed in the genus:[4]

Image Name Common name Distribution
  Tigrisoma mexicanum Bare-throated tiger heron from Mexico to northwestern Colombia, with one recorded sighting from the United States in Hidalgo County, Texas
  Tigrisoma fasciatum Fasciated tiger heron from Costa Rica through northwestern Argentina, southeastern Brazil, and Guyana; it has been recorded as a vagrant in Nicaragua
  Tigrisoma lineatum Rufescent tiger heron Central America through much of South America

Beautiful in flight, great markings on the feathers. Nest that mostly resembles jumble pile of twigs with openings large enough to allow eggs to fall through. Calls sounds like sick cow. A contrast in elegance and coarseness.
