Description wikipedia

The white-browed woodswallow (Artamus superciliosus) is a medium-sized (~19 cm) passerine bird endemic to Australia. The white-browed woodswallow has very distinctive plumage consisting of white brow over a black head with the upper body being a deep blue-grey and with a chestnut under body. The females are paler then the males. The white-browed woodswallow has a bifurcated (divided) tongue like most woodswallows. White-browed woodswallows are highly nomadic travelling in pairs to flocks from hundred to thousands of birds. They often wander irregularly around inland Australia, usually heading north for winter in the Northern Territory and central Queensland, and south in spring for nesting. White-browed woodswallows regularly associate with flocks of the masked woodswallow Artamus personatus.
