Slavonian Grebe (Podiceps auritus)
Rook (Corvus frugilegus)
Small 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.

An all shiny black crow with diagnostic bare, pale grey base of bill, and "baggy trousers". Juveniles lacks bare bill base and are difficult to separate from Carrion Crow. Young Rooks however, has a steeper forehead and more conical bill with less curved culmen. Tail is more rounded and base of wings more narrow. Flight action includes less gliding than Carrion Crow, and individuals are more spread when a flock flies.
Sound:Makes similar caws as Carrion Crow, but is harsher, softer, flatter with less rolling r's. Also gives a varied song of soft gurgling and rattling sounds, interwoven with calls at breeding ground.
