Cinnamon Bittern

Small heron of wet and open grassy areas such as flooded meadows and paddy fields. Uniformly bright rufous upperparts of adult male unmistakable. Female and juvenile have pale streaked belly, dark streaks and spots scattered on the wings and back, and are dark brown with some rufous tones above. Females often have light spotting on the wings, potentially causing confusion with female Schrenck's Bittern, which has brighter and more solid white spots and a prominent dark crown lacking in Cinnamon. Gives dry croaking clicks.

In Sri Lanka, the Cinnamon Bittern primarily inhabits wetland areas like flooded rice paddies, grassy marshes, reed beds, drainage ditches in coconut plantations, and coastal mangroves; often found near human settlements, particularly in lowland regions where these habitats are prevalent.

The Cinnamon Bittern in Sri Lanka eats fish, insects, and amphibians. They are often found in wetlands and marshes.
