The kingfisher is widespread as are the meadow pipit and pied wagtail. Other birdlife present are the sacred ibis, crested coua, kingfishers and Madagascar wagtail. Fast-flowing rivers attract specialist species, notably grey wagtail, dipper, common sandpiper, mandarin duck and goosander. White wagtail and black-capped kingfisher are rare migrants. There are currently two recognised subspecies of the African pied wagtail. The willie wagtail is insectivorous and spends much time chasing prey in open habitat. The pied wagtail is common in the town in the winter months. The white wagtail is an insectivorous bird of open country, often near habitation and water. The white wagtail ("Motacilla alba", ) is Latvia's national bird. The grey wagtail ("Motacilla cinerea") also uses the rich food supplies of the mountain brooks. This slim wagtail has a narrow white supercilium and a broken eye ring. It was often classified as a subspecies of the Western yellow wagtail. The willie wagtail is unrelated to the Eurasian wagtails of the family Motacillidae. The willie wagtail was a feature in Australian Aboriginal folklore. The larger willie wagtail is capable of tackling small skinks, but this is exceptional.
