Latin nameBotaurus stellaris FamilyBitterns and herons (Ardeidae) OverviewA thickset heron with all-over bright, pale, buffy-brown plumage covered with dark streaks and bars. It flies on broad, rounded, bowed wings. A secretive bird, very difficult to see, as it moves silently through reeds at water's edge, looking for fish. The males make a remarkable far-carrying, booming sound in spring. Its dependence on reedbeds and very small population make it a Red List species - one of the most threatened in the UK. Where to see themWetlands with large reedbeds, especially RSPB reserves at Minsmere, Suffolk and Leighton Moss, Lancashire. In winter it can also be watched at viewing sites in the Lea Valley, Hertfordshire. When to see themAll year round. Most visible in winter at certain sites. What they eatFish, amphibians and insects.
