Pygmy Owl (Glaucidium passerinum)
Rook (Corvus frugilegus)
Small size diagnostic. Small head in relation to body size, and distinct short white supercilia. Slightly protruding bill. Rather dark face, with only fine white markings and stern look. Juvenile lacks finely spotted crown. Bounding, woodpecker-like flight.
Sound:Calls in a clear voice, like a straight note blown on a recorder. Each note often followed by a rhythmic, trisyllabic accent a whole tone deeper than the first note.

CCAn 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.
