Wags its long tail up and down without pause, standing or walking; recognisable at a distance
Only black, white and grey with no yellow at all, separating it from yellow wagtail
White face and forehead with a black throat-and-breast bib that shrinks to a crescent in winter
Runs in quick steps across tarmac and car parks, stopping abruptly to snatch insects, never hopping
Deeply undulating flight with a sharp 'chiz-zik' call at each bound
Sharp two-syllable flight call; song is a loose string of the same notes
