Arenaria interpres
Adults unmistakable. White head with bold black markings and orangy brown back. Even more striking in flight, with white wedge on back, large white patches at base of wings, white wing-bars and black and white tail. Juvenile and winter plumage birds with similar white patches, but with darker head and greyish, dark brown back. Underside always pure white. Leaves a robust and compact impression, with heavy bill and square head.
Characteristic call: An explosive, hard, resonant and short "koi" or "kott" with a peculiar timbre, usually given in rapid or accelerating series. Alarm call/song more "wader-like", a staccato "kuvi-kuvi-vit-vit-vitua".
