White-browed Treecreepers are birds of the inland - in particular they prefer she-oak woodlands (Casuarina) but they are also widespread in mulga scrub and very occasionally in native pine (Callitris). Their closest relative is the Red-browed Treecreeper, a seemingly unlikely alliance because their life histories are quite different. Rather than communal, White-browed Treecreepers are rather solitary individuals. They occur in pairs in quite large territories and usually forage alone, but always within hearing of one another.
