binomial_authority = (Gould, 1842)The Welcome Swallow ("Hirundo neoxena") is a smallpasserine bird in theswallow family.It is a species native to
Australia and nearby islands, but not until recently toNew Zealand , which has been colonised in the last half century. It is very similar to thePacific Swallow with which it is often considered conspecific.This species breeds in southern and eastern Australia in a variety of habitats, 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 by
John Gould in "The birds of Australia"cite journal|last=Gould |first=John |coauthors= |month= December |year= 1842|title= Untitled [Mr. Gould exhibited and characterized the following thirty new species of Australian birds ...] |journal= The birds of Australia |volume= ix |issue= |pages= | ] 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".cite journal|last=Gould |first=John |coauthors= |month= February |year= 1843|title= Untitled [Hirundo neoxena sp. nov.] |journal= Proceedings of the Zoological Society of London |volume=10 |issue= |pages=131 ] cite journal|last= Mcallan |first= Ian A.W. |coauthors= |month= |year= 2004|title= [http://www.notornis.org.nz/free_issues/Notornis_51-2004/Notornis_51_3_125.pdf Corrections to the original citations and type localities of some birds described by John Gould and recorded from New Zealand] |journal= Notornis
volume= 51|issue= |pages=125–130 ]The Welcome Swallow is metallic blue-black above, light grey below on the breast and belly, and rusty on the forehead, throat and upper breast. It has a long forked tail, with a row of white spots on the individual feathers. These birds are about 15 cm long, including the outer tail feathers which are slightly shorter in the female. The call is a mixture of twittering and soft warbling notes, and a sharp whistle in alarm.
Young Welcome Swallows are buffy white, instead of rufous, on the forehead and throat, and have shorter tail streamers.
The winter range in northern Australia overlaps with that of wintering
Barn Swallow ("Hirundo rustica"), but the latter is readily separable by its blue breast band.cite book |title=Swallows & martins: an identification guide and handbook |last=Turner |first=Angela K |coauthors= Rose, Chris |publisher=Houghton Mifflin |year=1989 |id=ISBN 0-395-51174-7 ] Welcome Swallows readily breed close to human habitation. The nest is an open cup of mud and grass, made by both sexes, and is attached to a suitable structure, such as a vertical rock wall or building. It is lined with feathers and fur, and three to five eggs are laid. Two broods are often raised in a season.The female alone incubates the eggs, which hatch after two to three weeks. The young are fed by both parents, and leave the nest after a further two to three weeks.
These birds are extremely agile fliers, which feed on
insect s while in flight. They often fly fast and low to the ground on open fields in large circles orfigure 8 patterns. They will often swoop around animals or people in the open.Gallery
