The welcome swallow (Hirundo neoxena) is a small passerine bird in the swallow family Hirundinidae that is native to Australia and nearby islands. It has self-introduced into New Zealand in the middle of the twentieth century. It is very similar to the Pacific swallow with which it is often considered conspecific.
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.
The welcome swallow was first described in 1842 by John Gould in his The Birds of Australia as a member of the genus Hirundo, but the first publication is often incorrectly given as in the Proceedings of the Zoological Society of London.

The welcome swallow is a small fast-flying bird. Its flying style is circular in pattern with swift darting motions. It has graceful shape and flight, moreover it often flies... Wikipedia →
Possible
About 20% of wildlife watchers report a Welcome Swallow sighting in Hobart on a given day, based on 279 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 79 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.
January and November
In those months about 40% of wildlife watchers report a Welcome Swallow in Hobart on a given day, against under 5% in March to August, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Welcome Swallow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 cities where we can rate Welcome Swallow sightings, Hobart ranks 6th at about 20%. The best odds are in Auckland (New Zealand, about 70%), Brisbane (Australia, about 70%) and Melbourne (Australia, about 70%).
GBIF citizen-science records
It is estimated from how often the Welcome Swallow is recorded against all the birds logged in Hobart (279 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.
