The white-browed wagtail or large pied wagtail (Motacilla maderaspatensis) is a medium-sized bird and is the largest member of the wagtail family. They are conspicuously patterned with black above and white below, a prominent white brow, shoulder stripe and outer tail feathers. White-browed wagtails are native to South Asia, common near small water bodies and have adapted to urban environments where they often nest on roof tops. The specific name is derived from the Indian city of Madras (now Chennai). The white-browed wagtail is the largest species of wagtail at 21 cm length. It is a slender bird, with the characteristic long, constantly wagging tail of its genus. It has black upperparts, head and breast, with a white supercilium and large white wingbar. Unlike white wagtails it never has white on the forehead. The rest of the underparts are white. The female has the black less intense than in the male. Juveniles are like the females brown-grey where the adult is black.
