The species avoids saline waters but is equally abundant in fresh or brackish habitats (e.g. in estuarine or delta marshes), and may occasionally nest in stands of rushes (Scirpus or Papyrus spp.) if reeds are unavailable.

-

'''Status:''' Least Concern. Global Population: 110,000-340,000. The species is threatened mainly by the loss of reed marshes owing to habitat alteration through drainage, direct destruction, changes in traditional management (e.g. changes to reed harvesting regimes), sea level rise and salt water intrusion, the effects of wave action from boat traffic at the edge of open water, and pollution. Disturbance from humans during the nesting period is also a threat (e.g. disturbance from reed cutting, noisy recreation and water-sports, motor vehicles and hunting). The hunting of adults and collecting of eggs and chicks still occurs in some areas, and the species may suffer high mortalities in very cold winters (especially in sedentary populations). It is protected by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

'''Diet:''' Fish, frogs, small mammals and insects.

If a bittern senses that it has been seen, it becomes motionless, with its bill pointed upward, causing it to blend into the reeds. It is most active at dawn and dusk.
