Pied Wagtail Motacilla alba yarrellii is not generally considered an accomplished songster. Its song was described by Witherby et al., (1938) as, ‘a simple, but lively warbling twitter, consisting largely of slurred repetitions of call-notes with variants and modulations’. The song can, however, be surprisingly prolonged (e.g. https://xeno-canto.org/596084).
