The rufescent tiger heron (Tigrisoma lineatum ) is a species of heron in the family Ardeidae. It is found in wetlands from Central America through much of South America.

R
starts withThe rufescent tiger heron is a medium-sized heron, measuring 26–30 in (66–76 cm) in length, with a mass between 630 and 980 g (22 and 35 oz). The sexes are similarly plumaged. The adult's head, neck and chest are dark rufous, with a white stripe down the center of the foreneck. The remainder of its upperparts are brownish with fine black vermiculations, its belly and vent are buffy-brown, and its flanks are barred black and white. Its tail is black, narrowly barred with white. Its stout bill is yellowish to dusky, and its legs are dull green. Its irides, loral skin, and orbital ring are bright yellow. Unlike other tiger herons, it has no powder down feathers on its back.
The juvenile bird is rusty-buff overall, coarsely barred with black; the buff and black banding on its wings is especially pronounced. Its throat, central chest, and belly are white. It takes some five years to acquire adult plumage.
The rufescent tiger heron is found in wetlands from Central America through much of South America. It generally occurs below 500 m (1,600 ft), though it has been recorded as high as 1,600 m (5,200 ft) in Colombia.
It is largely crepuscular and generally solitary.
As might be expected of a species that spends most of its time by the water, much of the rufescent tiger heron's diet is aquatic-based, including fish, crustaceans, water beetles, and dragonfly larvae. It also takes adult dragonflies and grasshoppers. It typically hunts alone, standing hunched in shallow pools or wet areas of a forest while it waits for prey.
Although the rufescent tiger heron's population size and trend has not been quantified, its range is huge, so the International Union for Conservation of Nature lists it as a species of least concern.
