The White-browed Wagtail

The White-browed Wagtail or Large Pied Wagtail (Motacilla maderaspatensis) 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. They are common in 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) in South India. (From http://en.wikipedia.org/wiki/White-browed_Wagtail)
