Red-capped Robins are common across much of the drier parts of Australia. In Girraween, they are more likely to be found on the western side of the park.

Red-capped Robins eat insects and other invertebrates. The birds often sit on a low branch or stump and swoop down to the ground to catch their prey. They sometimes can be found feeding with other birds such as Pachycephala rufiventris Rufous Whistlers and Rhipidura leucophrys Willie Wagtails.

The breeding season is from June to January (Winter through Spring to Summer.) Male Red-capped Robins establish and defend a territory from other robins and the female builds a cup-shaped nest in the fork of a tree. The nest is made of grass, bark and other plant material and it is bound together with spider webs. It is often camoflaged with pieces of lichen and moss. The female lays two to four eggs and the incubation period is about two weeks. During that time, the male will look after her - protecting their territory and bringing her food. After the eggs hatch, he helps to feed the young. Juveniles can remain in their parents' territories for up to one and a half months after they have fledged.
