翻石鷸 Ruddy Turnstone (キョウジョシギ)

學名: Arenaria interpres

英名: Ruddy Turnstone

Family : Scolopacidae (鷸科) Length: 24cm




The Ruddy Turnstone (Arenaria interpres) is a small wading bird, one of two species of turnstone in the genus Arenaria. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. The dark, wedge-shaped bill is 2–2.5 centimetres (0.79–0.98 in) long and slightly upturned. The legs are fairly short at 3.5 centimetres (1.4 in) and are bright orange. At all seasons, the plumage is dominated by a harlequin-like pattern of black and white. Breeding birds have reddish-brown upper parts with black markings. The head is mainly white with black streaks on the crown and a black pattern on the face. The breast is mainly black apart from a white patch on the sides. The rest of the underparts are white. In flight it reveals a white wingbar, white patch near the base of the wing and white lower back, rump and tail with dark bands on the uppertail-coverts and near the tip of the tail. The female is slightly duller than the male and has a browner head with more streaking.
