Snowy Owl (Bubo scandiacus)
Sparrowhawk (Accipiter nisus)
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.
Small raptor with long tail and short, rounded wings. Quite similar to Goshawk, and female Sparrowhawks may approach male Goshawks in size (female much larger than male in both species). Upperparts grey in male, and brownish in female and juvenile. Underparts barred in buff in male, and brown barring in female and juveniles. Supercilium may be prominent in females. Less bulky than Goshawk, with more slender hips and less deep chest. The sharper corners of the tail is visible when soaring.
Sound:Series of short "ke-ke-ke-ke-ke", with rising pitch. Less resonant and less full than similar call of Goshawk, and much faster. Also a short "peeaaaa", shorter and more squeaky than Buzzard.
