Snowy Owl (Bubo scandiacus)
Dartford Warbler (Curruca undata)
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.

Small and slender Sylvia about the size of Lesser Whitethroat. The short wings, steep forehead and striking long tail alone is often enough for positive id. Upperparts dark slate grey, and underparts of male vinous red with finely white spotted throat. Female less brightly coloured with more brownish tones and less red underparts. Immature duller still, with brownish underparts rather than red. Yellow base of lower mandible in all ages and sex. Lacks the white moustache-stripe of Subalpine Warbler. Tail frequently held raised. Skulking behaviour. Prefers scrubs/Gorse and is usually only glimpsed when moving low from bush to bush, or when singing from more exposed perch.
Sound:Contact call a diagnostic, very nasal "chirr", quite different from other Sylvia, and used freely. Warning call a har "tuc". Song similar to Sardinian Warbler, but usually identifiable by frequently interspersed contact calls. Phrases are quite short, and pauses are as long or longer than the actual phrases. Each phrase typicall starts and ends with a more tonal segment than the regular chattering.
