Snowy Owl (Bubo scandiacus)
Sardinian Warbler (Curruca melanocephala)
Largely unmistakable. Male almost pure white with black dots. Female and juveniles white with heavy black barring, and may seem grey at a distance. Juveniles more finely barred than adult females, giving them a greyer appearance, with white neck and face. Body barrel-shaped, head small and rounded. Wing-tips more pointed than in other owls. Flight action both buzzard and owl-like, with surprising agility. Note that several species of owls may seem completely white to the untrained eye when suddenly appearing in car headlights etc.
Sound:Song consists of single utterances or series of "aooo", recalling Great Black-backed Gull, and is far carrying. Male warning call a deep and harsh "groat grat grat", with accented endings of each syllable. Female warning call higher pitched. Also various other high pitched calls.

CCCC-sound:Niels Krabbe, Licence,Link.
Slender warbler with long tail, short wings and pointed bill. Restless and alert with frequently raised crown feathers and dark eye framed in red. Male with black head, white throat, greyish upperparts and off-white underparts. Female less striking, with grey head grey-brown upperparts, distinct buff flanks and paler belly. Both sexes with white sides and corners to tail. Rarely sits exposed, and usually betrays itself by it's frequently used scolding call. Often just glimpsed when it dives into a bush, spreading it's tail and showing the white markings.
Sound:Epitome of mediterranean sylvias, and learning the songs of the genus should start with extensive listening to this species (use xeno-canto link below). Scolding call a machinegun-like, short and harsh rattle. Usually consisting of 2-5 notes with some variation in timbre and delivery. Song a stream of varied, short notes, constantly interspersed with variations of the scolding call. Phrases 2-5 sec. long. Easily confused with several other sylvias, especially in the eastern part of the Mediterranean. Rattling sound (in both song and call) differs from most other congeners by being considerably harder and more "smacking". Dartford Warbler most similar, but usually betrays itself by it's characteristic and frequently used contact call (also interspersed when singing).
