Winter migrant to the island where it can be occurred as several races while Grey-headed wagtail (M.f. thunbergi) is the commonest of them which can be seen throughout the country in grasslands and marshes.  There are few other races (M.f. bema [Syke’s Yellow wagtail], M.f lutea [Yellow-headed Wagtail], M.f. melanogrisea [Black-headed Yellow wagtail], M.f. simillima [Siberian Yellow Wagtail], M.f. feldegg) those are rare to very rare migrants and vagrants to the dry lowlands. During its stay in Sri Lanka Grey-headed wagtail  feeds as scattered flocks on grasslands, dry tank beds, paddy fields, etc often accompanying with cattle.  It roosts communally in reed-bed or swamp scrub during the night. Grey-headed wagtail  breeds from North-eastern Europe to North-western Siberia
