White Wagtails are very lively small birds. Their flight is wavy and on the ground the graceful tail wags up and down continually. They are also fairly aggressive and sometimes ‘fight’ with their own reflection, for instance in a shiny hub cap of a car. In the winter they migrate Southward, but many birds in Northern and Eastern Europe migrate only to the West, to benefit from the relatively warm sea-climate. In the winter the bird generally lives in small swarms that are often seen on farmland.
