It lives solitary or as pairs and feeds on fish, frogs, insects and such other small animals found in aquatic habitats. Chestnut bittern is a partially nocturnal shy bird, though it is not unusual of encountering them during the day time. It breeds from June to July and lays three to five eggs in a nest made out of dry grasses and hidden in reeds or tussock in a marsh.
