The fasciated tiger heron (Tigrisoma fasciatum) is a species of heron in the family Ardeidae. It is present in southern Central America and parts of northern and central South America, where its natural habitat is rivers.
In 1988 the fasciated tiger heron was categorized by the IUCN as Near Threatened but as of 2004 they have been recategorized as Least Concern. First described as Ardea fasciata by George Such in 1825 from a specimen collected in Serro do Imbé, Brazil, the fasciated tiger heron is now one of three species assigned to the genus Tigrisoma. In the past, it has sometimes been considered as a subspecies of the rufescent tiger heron. It has three subspecies:

With luck
About 10% of wildlife watchers report a Fasciated Tiger Heron sighting in Arenal Volcano National Park on a given day, based on 849 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 187th most-seen of the 503 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
January–April, July and September
In those months about 10% of wildlife watchers report a Fasciated Tiger Heron in Arenal Volcano National Park on a given day, against under 5% in May–June, August and October–December, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Fasciated 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.
Among the best
Of the 24 parks where we can rate Fasciated Tiger Heron sightings, Arenal Volcano National Park ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Manu National Park (Peru, about 10%), Sierra de la Macarena National Park (Colombia, about 10%) and Darién National Park (Panama, about 10%).
GBIF citizen-science records
It is estimated from how often the Fasciated Tiger Heron is recorded against all the birds logged in Arenal Volcano National Park (849 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.
