Maríuerla Motacilla alba

Distinctive but variable: all plumages are some bold combination of black, white, and gray. Shows considerable variation in plumage across the world, but never has a clear, thin and contrasting eye-brow like White-browed or Japanese Wagtail. Occurs in varied open habitats, from wild grassy areas and wetlands to paved car parks and grassy lawns. Usually seen as singles, pairs, or small groups walking and running around, pumping the long, white-sided tail up and down. Identified easily in flight by its loud, thick and distinctive “tsee-tsee’ call.
