How to recognize it

Large, stocky heron with buff-brown plumage and dark streaks
Dark crown and back; pale buff edge to feathers
Usually hidden in reeds; freezes upright with bill pointed up
Deep spring boom, bull-like and far carrying

The Eurasian Bittern is usually hidden in reeds and other thick cover, so it is easy to miss. When it freezes with its neck stretched upright, it blends into the stems and almost disappears.

It is a shy, secretive hunter that prefers to stay still rather than show itself. In spring the male gives away its presence with a deep, far-carrying boom, most often heard at dusk, at night, or early in the morning.

It lives around standing water and slow-moving wetlands with dense reedbeds. It feeds mainly on fish, and also takes frogs, newts, aquatic insects, and other small prey; some populations stay through winter, while others move south.
