Behaviour

Social behaviour: Territorial?/ roaming? Mobility: Sedentary Elementary unit: Family clan

(Next to Yellow-rumped Thornbills,) Buff-rumped Thornbills are one of only two species of thornbill observed by us to regularly forage on the ground. We have seen them hunting for insects on our lawn and paddock. Having caught something, they fly to a nearby tree with dense foliage before eating the insect.

Birds in general, not only Buff-rumped Thornbills, will try to be hidden from view while studying a human observer. The photo taken below does not just show a chance configuration, but this type of behaviour is observed by us regularly. Small, shy bird species, such as e.g. Chestnut-rumped Heathwrens, are particularly good at this.

Food, Diet

To the best of our knowledge all thornbills feed primarily on small insects, but we have also seen some taking nectar.
