Black bittern

The juvenile is like the adult , but dark brown rather than black. 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. Breeding. Their breeding habitat is reed beds. They nest on platforms of reeds in shrubs, or sometimes in trees. Three to five eggs are laid. Diet. Black bitterns feed on insects, fish, and amphibians.
