The western yellow wagtail (Motacilla flava) is a small passerine bird in the wagtail family Motacillidae, which also includes the pipits and longclaws. This species breeds in much of temperate Europe and Asia. Most populations are migratory, moving south to tropical Africa and southern Asia for the winter; the small population breeding in Egypt is however resident there.
It is a slender 15–16 cm long bird, with the characteristic long, constantly wagging tail of its genus. It is the shortest tailed of the European wagtails. The breeding adult male is basically olive above and yellow below. In other plumages, particularly in juveniles, the yellow may be diluted to whitish. The heads of breeding males come in a variety of colours and patterns depending on subspecies. The call is a high-pitched jeet. This insectivorous bird inhabits open country near water, such as wet meadows. It nests in tussocks, laying 4–8 speckled eggs.
The western yellow wagtail was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under its current binomial name Motacilla flava. In 1555 the Swiss naturalist Conrad Gessner had used the identical... Wikipedia →

Rare
Under 5% of wildlife watchers report a Western Yellow Wagtail sighting in Kollam on a given day, based on 94 verified sightings from GBIF citizen-science data. It is the 80th most-seen of the 173 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January, March and October–November
In those months about 10% of wildlife watchers report a Western Yellow Wagtail in Kollam on a given day, against under 5% in February, April–September and December, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Western Yellow Wagtail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
48th of 97
Of the 97 cities where we can rate Western Yellow Wagtail sightings, Kollam ranks 48th at under 5%. The best odds are in Agra (India, about 30%), Rajkot (India, about 30%) and Kampala (Uganda, about 20%).
GBIF citizen-science records
It is estimated from how often the Western Yellow Wagtail is recorded against all the birds logged in Kollam (94 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.
