The male is spectacularly coloured, even more so when assessed against the backdrop of reddish soil of the interior. The cobalt blue mixed with white and brown is very distinctive. Females and immatures are less colourful, being predominantly greyish-brown with pale lores, orange-brown bill and a blue wash to the tail. Nob-breeding males resemble the female, but have a black bill. On two offshore islands (Barrow and Dirk Hartog) of Western Australia, the male’s rich blue colour is replaced with black. It widespread in driers areas lignum, saltbush and other low shrubs, where its high-pitched trill typically betrays its presence.
