The little bittern has a length of 33–38 centimetres (13–15 in) and a wing span of 52–58 centimetres (20–23 in). It is the smallest of the breeding herons of Europe and is characterised by its tiny size, long and sharp bill and thick neck.

The bittern has sometimes been regarded as a subspecies of the little bittern (Botaurus minutus), or of the New Zealand bittern (Botaurus novaezelandiae).However, molecular evidence has shown it to be more closely related to the yellow bittern (Botaurus sinensis) than to the African and Palaearctic forms of the little bittern, and it is now recognised as a full species.
Bittern. The impetus for creating the Ham Wall reserve was the plight of the bittern, with only 11 males present in the UK in the 1997 breeding season. Much of its reed bed habitat was deteriorating, and key coastal sites in eastern England were at risk of saltwater flooding, so an opportunity to create a new inland site was attractive to the RSPB.
The roost is in National wildlife reserves such as Westhay Moor, Ham Wall and Shapwick Heath. The area also contains one third of the UK breeding population of Bitterns and the first known UK breeding populations of Great White Egret, Little Bittern, and Night Heron. [2]
