Purple Heron (Ardea purpurea)
Bittern (Botaurus stellaris)
Most similar to Grey Heron but leaves a much darker impression, has a slimmer body, neck and wings. The bill is markedly thinner and is almost level with the flat forehead. Adult birds have black longitudinal stripes along the rufous sides of the neck, and a black crown. Immature birds have more diffuse streaking, and are sandy brown instead of grey. Coverts are also brownish, and partially remains in first summer birds. In flight the dark underwings of adult birds are obvious. The folded neck creates a bigger and more angular bulge and the very long toes are often sprawled. More secretive behaviour than Grey Heron.
Sound:Quite similar to Grey Heron, but not so vocal. Pitch slightly higher and remains stable throughout the short call. Volume muffled and timbre drier.

CCBulky, golden-brown heron with thick neck and short legs. Largely unmistakable but skulky behaviour makes it difficult to observe, as it generally forages hidden in reed-beds. Plumage mottled above, with coarse stripes below. Primaries and most secondaries with dark barring, in contrast to paler coverts. May recall Eagle Owl in flight with broad, rounded wings and retracted neck, but wings are bowed and legs trail behind tail. Crown and moustache stripe black in adult and brown in immature birds. Betrays its presence by it's far reaching song.
Sound:Flight call a deep croaking "graat". Song unmistakable and far reaching (up to 5 km). Pitch very deep, with timbre similar to blowing on a big empty bottle. At close range an "inbreath" is also audible (1-3 dampened, higher pitched introductory notes).
