Wooded banks of slow flowing streams and rivers, marsches, swamps or mangroves.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Present in all the regions of Brazil, guianas,Southeast Mexico, Honduras, Argentina and Uruguay. It inhabits the banks and shores of rivers and lakes with densely grown edges. This species lives generally solitary, becoming more active at dawn and during twilight. Catches its prey by walking slowly or standing completly still, in shallow waters or puddles in the interior of the forest. When disturbed, it remains immovable until flying, up to a higher save place in the trees. The nest is a platform mostly built soilitary. Not much scientific data are available on this species in the wild.
Rufescent Tiger Heron status Least Concern

Migration

Sedentary in all of its range.
