Welcome Swallow

Overview

The Welcome Swallow is the common swallow of Australia and, since natural colonisation in the twentieth century, New Zealand as well. It is closely related to the Northern Hemisphere's Barn Swallow and shares its graceful, agile flight and mud-cup nesting habits.

• Family: Hirundinidae (swallows and martins)
• Distribution: Australia, New Zealand, and nearby islands
• Notable trait: constant fast, swooping flight low over open ground

Feather Identification

Upperpart feathers are glossy blue-black with a metallic sheen, while the forehead and throat are rufous-chestnut, fading to a pale buff or grey-white on the rest of the underparts. The tail is deeply forked with elongated outer feathers and small white spots visible on the underside in flight, similar in structure to the Barn Swallow's tail.

• Overall pattern: glossy dark upperparts, rufous face, pale belly
• Key mark: deeply forked tail with white spots near the tips
• Compare with: Barn Swallow (very similar structure; Welcome Swallow typically shows a plainer breast band and duller underparts)

Plumage

Sexes look similar, though males often have slightly longer tail streamers. Juveniles are duller with shorter tail forks and a paler, less rufous face, gaining full adult plumage and tail length after their first moult. There is no distinct seasonal plumage beyond normal feather wear and renewal.

Habitat & Range

Welcome Swallows favour open farmland, wetland edges, coastlines, and urban areas, frequently nesting on buildings, bridges, and other structures. Southern populations are partially migratory, moving north in the non-breeding season, while others are resident year-round.

Behavior & Field Notes

This species feeds almost entirely on flying insects caught on the wing during fast, low, swooping flight, often over water or open fields. It nests in mud cups built under eaves, bridges, or ledges, and frequently gathers in large flocks on wires outside the breeding season. Calls include soft twittering notes given in flight.

• Diet: flying insects caught in the air
• Voice: soft, continuous twittering
• Field note: frequently seen skimming low over grass or water in pursuit of insects
