About the Eurasian Bittern

The Eurasian bittern or great bittern is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race breeding in parts of Europe and across the Palearctic, as well as on the northern coast of Africa, while the southern race is endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects.

How to identify it

Bitterns are thickset herons with bright, pale, buffy-brown plumage covered with dark streaks and bars. As its alternative name suggests, this species is the largest of the bitterns, with males being rather larger than females. The Eurasian or great bittern is 69–81 cm (27–32 in) in length, with a 100–130 cm (40–50 in) wingspan and a body mass of 0.87–1.94 kg (1 lb 14+1⁄2 oz – 4 lb 4+1⁄2 oz). The crown and nape are black, with the individual feathers rather long and loosely arranged, tipped with buff narrowly barred with black. Voice: The mating call or contact call of the male is a deep, sighing fog-horn or bull-like boom with a quick rise and an only slightly longer fall, easily audible from a distance of five kilometres (three miles) on a calm night. The call is mainly given between January and April during the mating season.
