The wire-tailed swallow (Hirundo smithii) is a small passerine bird in the swallow family. It is mainly resident, but populations in Pakistan and northern India migrate further south in winter. The genus name Hirundo is the Latin word for swallow. The species name smithii commemorates Christen Smith, a Norwegian botanist and geologist.
The wire-tailed swallow is a small swallow, measuring 18 cm (7.1 in) in length. It has bright blue upperparts, bright white underparts and a chestnut cap. Immature birds lack tail wires, and have dull brown (rather than chestnut) caps. The species is named for the very long filamentous outermost tail feathers, which trail behind like two wires. The sexes are similar in appearance, but the female has shorter "wires". Juveniles have a brown crown, back and tail.
This bird is found in open country near water and human habitation. Wire-tailed swallows are fast flyers and they generally feed... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Wire-tailed Swallow is recorded against all the birds logged in Vasai-Virar (140 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.
