This is quite a familiar black and white little bird that keeps bobbing its long tail. Found in various habitats, it appears to get quite used to people, especially in urban environments like towns and cities. I followed this lively one along a pebbly beach before it found this rock to sit on for a better view. Common and widespread throughout Britain, it mainly feeds on insects.
