Feeding ecology and diet

Most of the acanthizids are gleaners, taking small invertebrates from the foliage, from twigs, branches and trunks, or from the ground. Weebills and the gerygones include more active modes, such as snatching and hovering. Occasionally, insects are held under the feet. Within a habitat, different species often use different microhabitats. For instance, striated thornbills (Acanthiza lineata) glean from foliage in the canopy and subcanopy, while brown thornbills (A. pusilla) forage among shrubs and buff-rumped thornbills

(A. reguloides) feed from the ground or bark. Although the food of most species is predominantly invertebrates, seeds and fruits are occasionally eaten. Whitefaces consume large quantities of seeds.
