Nest |
"bungobittah", "lar", "malunna", "jindi" [bundjalung] = nest [Aboriginal] |
Type: Tunnel | Material: Soft soil; grass, rootlet, feather lining | Height above ground: N/A |
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.

Behaviour |
Social behaviour: Communal | Mobility: Sedentary | Elementary unit: Flock |
We have repeatedly found White-backed Swallows hawking for insects above (dry) creek beds and gullies.

calls were
recorded on 16 October 2014, hawking for insects; this photo

White-backed Swallows seen hawking for insects above (dry)
creek beds
are also regularly observed by us in low flight above nearby
paddocks,
sometimes together with other species of swallows and/or martins
