The rufescent tiger heron (Tigrisoma lineatum) is a species of heron, birds in the family Ardeidae. It is found in wetlands from Central America through much of South America. The rufescent tiger heron was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected in Cayenne, French Guiana. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Ardea lineata in his catalogue of the Planches Enluminées. The rufescent tiger heron is now placed in the genus Tigrisoma that was erected by the English naturalist William Swainson in 1827. The genus name Tigrisoma combines the Ancient Greek tigris, meaning "tiger" and somā, meaning "body"; the specific epithet lineatum is from the Latin lineatus meaning "marked with lines".

Rare
Under 5% of wildlife watchers report a Rufescent Tiger Heron sighting in El Palmar National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 126th most-seen of the 151 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Rufescent Tiger Heron in El Palmar National Park on a given day, against under 5% in September to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Rufescent Tiger Heron sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 23
Of the 23 parks where we can rate Rufescent Tiger Heron sightings, El Palmar National Park ranks 14th at under 5%. The best odds are in Parque Estadual Encontro das Águas (Brazil, about 80%), Cuyabeno Wildlife Reserve (Ecuador, about 40%) and Iberá National Park (Argentina, about 40%). All parks ranked.
Same family: Ardeidae
The closest relatives of the Rufescent Tiger Heron that you can see in El Palmar National Park (family Ardeidae, Herons, Egrets, and Bitterns) are Whistling Heron (about 20%), Cocoi Heron (about 10%) and Great Egret (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rufescent Tiger Heron is recorded against all the birds logged in El Palmar National Park (23 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
