They forage for berries and insects on the ground, or clambering through bushes and undergrowth. Dragonfruit stems are scandent (climbing habit), creeping, sprawling or clambering, and branch profusely. Pecks rapidly and probes dense vegetation, clambering along and hanging from small twigs. They prefer clambering through thickets in bushveld, marshes, riparian fringes or coastal bush. Most live in scrubland and frequently hunt food by clambering through thick tangled growth.
