The White-breasted Robin is endemic to south-western Australia. It often perches sideways on a trunk, then darts to catch prey from the ground or air.
It is about 15 cm long. The head and upper back are grey, the wings and tail are darker grey, and the underparts are white. In flight, a white bar shows at the base of the tail.
It uses karri forest, streamside thickets within forest, and coastal heath. During courtship the male feeds the female; she builds a cup nest in a small tree fork. The guide also records young from earlier years helping parents feed nestlings.
