Red-footed Falcon (Falco vespertinus)
Snowy Owl (Bubo scandiacus)
Small falcon recalling both Kestrel and Hobby at a distance, but most likely to be confused with latter. Adult male unmistakable with ashy grey plumage and rufous red "trousers". Colour of trousers not always obvious, but silvery upperwing often visible in flashes at distance. Adult female also distinct with almost unstreaked buff underparts and under wing-coverts, buff neck and crown, dark mask and white cheeks. Immature most likely to be confused with Hobby but differs in barred upper side of tail, pale forehead, white (half)collar, contrasting dark trailing edge to wing and more striking fringes to coverts. Underparts also less heavy streaked. Flight profile similar to Hobby but tail slightly longer and more rounded. Hunts insects in flight, but in contrast to Hobby, hovers frequently and with deeper wingbeats than Kestrel.
Sound:Flight call very similar to Hobby, a wryneck-like series of "kew kew kew kew", each call falling rapidly in pitch. Sometimes given in a harsher more staccato version. Very vocal at colony with various squeaky and whimpering begging calls.

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.
