Physical description Click here for a physical description White-backed Swallows are similar in size to other swallows found in Australia, while martins are smaller. They have a mottled grey cap above white eyebrows and a wide dark-grey eye stripe that merges into a brown band acros the nape of the neck. Part of the front (throat, breast and underwing coverts) is white, while the rest (belly, vent, undertail and flight feathers) is all dark-grey. The back is white, while the rest of the upperparts (mantle, rump, upperwings and uppertail) is also all dark-grey. The tail is deeply forked. The eyes have dark irises. The very short bill is black; the legs and feet are grey. Juveniles have shorter tails and duller colours. Their cap, and possibly also the chin, is buff-coloured.

Taxonomy, classification See White-backed Swallow at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the White-backed Swallow is available HERE . NB: Reports on ebird of birds submitted by birdwatchers from the Australian Outback tend to be clustered along roads and public areas such as camp grounds; in such cases their distribution is not a good representation of the overall distribution of the species. White-backed Swallows are endemic to Australia. They populate roughly the southern part of the Australian continent, up to about the tropic of Capricorn (only in WA they go farther North, into the Gascoyne). There are two major populations, one in WA and one in the south-east of the continent. Their range in WA encompasses about the western three-quarters of the state, up to about Eighty Mile Beach in the North and the Gibson Desert NR in the East. They are not found on the south-western tip of WA and rarely in the Perth area. The range of the second large population extends from the southern NT via most of SA, northern VIC and all of NSW into southern QLD, including the Simpson Desert. They are not found along the South coast of VIC and up to about Woollongong, NSW, and only rarely further up North along the NSW coast. Occasionally, especially after substantial inland rainfall, White-backed Swallows can extend their range to encompass basially the entire southern continent (including the major sandy deserts), up to a line connecting about Eighty Mile Beach, WA, with Mt. Isa, QLD and Rockhampton, QLD. White-backed Swallows are mostly found in open, sandy country, often above open grassland and low shrubs. During the breeding season they have a strong preference for habitats around (often dry) creek beds (they nest in nest tunnels dug into steep banks).

Sightings Click here for sighting information White-backed Swallows used the summer months to hunt insects above the paddocks where we lived in 2003-2006, 20 km South of Narrabri, NSW. They came in flocks of around 50 birds, but did not settle to allow us taking a photo. This is the only time we have seen them in a flock. Since then, White-backed Swallows have since been seen semi-regularly, usually as pairs, in Eulah Creek, NSW, where they are usually found hawking for insects above paddocks, a farm dam and sometimes also around a house. Two White-backed Swallows were spotted by C. Hayne 35 km East of Moree, NSW, in September 2011. A pair of White-backed Swallows was spotted by us on the outskirts of Tibooburra, NSW, in September 2012, while M. Eaton found the species at Kilcowera Station, between Thargomindah and Hungerford, QLD, in June 2020. Four birds were spotted hawking for insects above the at the time dry bed of Maules Creek, 20 km South-East of the community of Maules Creek, NSW, in May 2013. In October/November 2014 we spotted White-backed Swallows 15 km East of Narrabri, NSW. They were seen there over an extended period, once chasing away one of their kind and once seen exploring a steep creek bank, possibly exploring the area for a suitable site for their tunnel nest. Numbers varied from only a pair to about 25-30. White-backed Swallows were spotted by us at the same location again in September 2015, when one bird was seen carrying nest material. In October 2015 we found a nest tunnel at the same location. Two White-backed Swallows were spotted in the same location in subsequent breeding seasons (2016 - 2018). Starting in August 2023, a pair was found at a site with a similar undercut creek bank, just 2 km downstream of the old nest site. In May 2022 we found 4 juvenile White-backed Swallows near water in woodland close to Kenebri, NSW. M. Eaton reports finding White-backed Swallows along the Strzelecki Track, e.g. at the Montecollina Bore, SA, in June 2022.

White-backed Swallows are the only Australian swallows or martins to use a tunnel for nesting. We found a pair nesting in close proximity to several other tunnel-nesting species, such as Rainbow Bee-eaters, Red-backed Kingfishers and Striated Pardalotes.

Our limited experience so far suggests that, at least in their nesting behaviour, White-backed Swallows are the complete opposite of Welcome Swallows. They are very shy around their nest and do not tolerate the proximity of humans. They watch the surroundings of their nest from the air and don't approach the nest tunnel when suspecting a potential threat. The approach, after flying in circles above the general area of the nest site, is quick and furtive.
