Bittern (Botaurus stellaris)
Slavonian Grebe (Podiceps auritus)
Bulky, 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).
Song (note; recording not audible on small mobile devices):

CCSmall and compact grebe. May be confused with Red-necked Grebe or Black-necked Grebe. In all plumages; short bill and flat crown. Thicker neck than Black-necked Grebe and lacks steep forehead. Dark bill with pale tip, often surprisingly visible. Summer; chestnut neck, black head and golden crests. Sexes alike, but male slightly brighter coloured. Winter; black upperparts and white underparts (differs from Little Grebe). Pure white cheeks in adults (grey in Red-necked Grebe). Juveniles may show faintly streaked cheeks, but still giving a white impression.
Sound:Varied. Vibrating, wailing, dry and cackling sequences. A mewing, falling and far-reaching "kiaa" and various rattling sounds.
