The welcome swallow (Hirundo neoxena) is a small passerine bird in the swallow family Hirundinidae that is native to Australia and nearby islands.

This species breeds in southern and eastern Australia in a variety of habitats, mostly in open areas, man-made clearings or urban environments, but not desert or dense forest. Eastern populations are largely migratory, wintering in northern Australia. Western birds and those in New Zealand are mainly sedentary.

GBIF citizen-science records
It is estimated from how often the Welcome Swallow is recorded against all the birds logged in Perth (4,259 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.
