The Little Bittern (Ixobrychus minutus) is a wading bird in the heron family Ardeidae, native to the Old World, breeding in Africa, central and southern Europe, western and southern Asia, and Madagascar. Birds from temperate regions in Europe and western Asia are migratory, wintering in Africa and further south in Asia, while those nesting in the tropics are sedentary. It is rare north of its breeding range.
It is a very small bittern; at 27–36 cm in length, 40–58 cm wingspan and 60-150 g weight. The smallest specimens are perhaps the smallest herons on earth. It has a short neck, longish bill and buff underparts. The male’s back and crown are black, and the wings are black with a large white patch on each wing. The female has a browner back and a buff-brown wing patch.
The Little Bittern’s breeding habitat is reedbeds. It nests on platforms of reeds in shrubs, and 4-8 eggs are laid. It can be difficult to see, given its skulking lifestyle and reedbed habitat.
These bitterns feed on fish, insects and amphibians.
Very common bird in the Danube Delta during april- september.
