Appearance:

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.

Appearance:

Differs from Barn Swallow in all plumages by pale throat and black under tail coverts, which are visible at greater distance than the red rump. Rufous cheeks and collar. Underparts finely streaked, giving the bird a slightly "dirty" look from a distance, with less contrast to the upperparts than in Barn Swallow. Immature birds with short streamers and buff cheeks and rump. Build more compact than Barn Swallow, with shorter bill, rounded wings and slightly shorter streamers. Flight slower and with more frequent gliding.

Sound:

Less vocal than Barn Swallow. Song slower, and less energetic. Each phrase starts with a few staccato notes, leading to a short, twittering sequence of a few seconds length, with some drawn notes. Timbre is metallic and "broken", and quite diagnostic.
