The white-browed woodswallow (Artamus superciliosus) is a moderately sized passerine bird native to inland Australia. Like all woodswallows, it has a brush-tipped tongue but feeds almost exclusively on flying insects.
White-browed woodswallows are highly nomadic. Pairs, small parties, and sometimes flocks of thousands wander irregularly around inland Australia, often trending north to winter in the Northern Territory and central Queensland, and south in spring to nest. Their heartland is the area centered on the Murray-Darling Basin, but they range far beyond this area, and in drought years frequently reach coastal southeast Australia. They are uncommon in Western Australia but small numbers regularly associate with flocks of the masked woodswallows. source
