Appearance:

Unmistakable due to the extremely long, red legs. High contrast plumage with pointed, black wings (both upper and under-side) and white underparts. Tail white, with white wedge extending up back. Back of adult male sooty black, while brownish black in female and immature. Head all white or with black markings independent of sex (males more often have black markings than females though). Immature with faint, pale fringes to coverts, and white trailing edge to secondaries visible in flight.

Sound:

Most vocal at breeding ground. Various short,sharp "kyp" may resemble both Avocet, Coot and Spur-winged Lapwing (Vanellus spinosus). While a tern-like "kee-arr" is more distinct. Note that immature birds have a different contact call closely resembling Wood Sandpiper, but do not utter it in series.

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.
