Appearance:

A beautiful, very pale owl with a diagnostic, heart-shaped face and black eyes. Underparts white to buff. Buff-bellied individuals most likely to be confused with other owls, but note lack of barring and streaking. Instead the underparts may be covered in small spots. Underwing almost white. The white bellied birds may recall the much larger Snowy Owl, but has much slender wings, slender body, longer legs and protruding head. Posture upright, both on ground and when perched. Flight-pattern variable, but often hunts from low above ground in slow and buoyant flight.

Sound:

Large repertoire of mainly hissing and screeching sounds. Song consists of a single, drawn screech, lasting about a second and is often performed in flight. Starting in a very hoarse tone, then progressing with a rising pitch into a more burbling sound, before suddenly ending.

Appearance:

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.
