Black bittern:

The black bittern (Ixobrychus flavicollis) is a bittern of Old World origin, breeding in tropical Asia from Bangladesh, Pakistan, India, and Sri Lanka east to China, Indonesia, and Australia. It is mainly resident, but some northern birds migrate short distances.


In flight in Kolkata, West Bengal, India

This is a fairly large species at 58 cm (23 in) in length, being by some margin the largest bittern in the Ixobrychus genus. Compared to related species, it has a longish neck and long yellow bill. The adult is uniformly black above, with yellow neck sides. It is whitish below, heavily streaked with brown. The juvenile is like the adult, but dark brown rather than black.

Their breeding habitat is reed beds. They nest on platforms of reeds in shrubs, or sometimes in trees. Three to five eggs are laid. They can be difficult to see, given their skulking lifestyle and reed bed habitat, but tend to fly fairly frequently when the all black upperparts makes them unmistakable.

Black bitterns feed on insects, fish, and amphibians.

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 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.
