The white wagtail (Motacilla alba) is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws.

In total, there are between 9 and 11 subspecies of M. alba; in Ireland and Great Britain, the black-backed subspecies known as the pied wagtail (M. a. yarrellii) predominates.
The white wagtail is an insectivorous bird of open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas, it has adapted to foraging on paved areas such as car parks. It nests in crevices in stone walls and similar natural and human-made structures.
It is the national bird of Latvia and has featured on the stamps of several countries. It is listed as being 'of least concern' by IUCN.

With luck
About 10% of wildlife watchers report a White Wagtail sighting in Kolkata on a given day, based on 1,473 verified sightings from GBIF citizen-science data. It is the 44th most-seen of the 247 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
November to January
In those months about 30% of wildlife watchers report a White Wagtail in Kolkata on a given day, against under 5% in April to August, the lowest months. Those are among Kolkata's driest months, with about 15 mm of rain a month against 330 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most White Wagtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
129th of 210
Of the 210 cities where we can rate White Wagtail sightings, Kolkata ranks 129th at about 10%. The best odds are in Sendai (Japan, about 80%), Tehran (Iran, about 80%) and Antalya (Turkey, about 70%).
Same genus: Motacilla
The closest relatives of the White Wagtail that you can see in Kolkata (genus Motacilla, Wagtails) are Citrine Wagtail (about 10%) and Eastern Yellow Wagtail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White Wagtail is recorded against all the birds logged in Kolkata (1,473 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
