The capped heron normally inhabits swamps and ditches in wet grasslands or rainforests. Sometimes it can venture into deeper ponds and rivers. They prefer to forage on the shore or in floating vegetation,  but have also been observed in trenches of coffee plantations and flooded rice fields. Capped herons hunt mainly for fish, but also aquatic insects and larvae, tadpoles, and frogs.
The insects are hunted in the nearby vegetation along the river or pond, and the fish in the shallow waters. In a typical hunting sequence the heron will stand erectly searching for potential prey; after locating it they will crouch slowly and extend their neck; finally they will introduce their beak into the water at a great speed to catch the prey. They can also use the same sequence while walking in the shallows. They usually walk slowly, covering the same area repeatedly pausing for a few seconds, then slowly moving one foot to take a new step.
Capped herons move frequently between feeding sites, sometimes flying up to m. They may be crepuscular ,  but have been observed foraging during broad daylight, unlike the night-herons. Capped herons are strongly territorial; the same bird may be seen at a foraging site for weeks at a time. The capped heron is normally solitary, although there are cases where they have been found in couples or groups.
There is very little known about the reproduction of this species. Based on birds with a similar biology, it is likely that they maintain family groups and care for young even after the young have reached the fledgling stage. There may be a two-cycle breeding pattern, with northern and southern populations breeding at different times of the year. This species has an extremely large range, and hence does not approach the thresholds for a Vulnerable rating under the range-size criterion.
The population size has not been quantified, and the trend is not known, but it is not believed to approach the thresholds for Vulnerable under the population size or trend criteria. For these reasons the species is evaluated as Least Concern. The capped heron appears to be adaptable and may be expanding its use of man-made habitats. From Wikipedia, the free encyclopedia.
