Striated Herons are also found in mangroves but are smaller (up to 49 cm) and are lighter grey with a black cap.
Black Bitterns are seen in daylight more often than other bitterns.
The Black Bittern is a sooty black or dark brown bittern with a yellow patch on the sides of the neck, extending from the throat to the wing. The feathers on the crown and lower neck are almost plumes. The legs are dark.
Black Bitterns roost and nest in trees, and are found in tree-lined wetlands and in mangroves. They forage in both daylight and darkness, mainly from shady trees over water, but may be seen during the day in open areas of short marshy vegetation and along creeks in shrubby vegetation.
Black Bitterns are found in coastal south-western, northern and eastern Australia south to far eastern Victoria.
Black Bitterns are sedentary throughout the year.
Feeding and diet
Black Bitterns feed on a wide range of small animals, but mainly fish and amphibians. They stalk prey slowly or stand and wait for prey to emerge, but may sometimes plunge at it from a perch, before stabbing it with their sharp bills.
Loud repeated cooing.
Black Bitterns nest in trees over water. The nest is a loose platform with a shallow depression in the centre.
- Breeding season: September to April
- Clutch size: Up to five, usually three
Loss of wetlands by draining reduces the range of habitats available to the Black Bittern.
